Anyone bought one? Looks to be price wise possibly make a good starter compressor?😎😊 I'll bite and buy one but won't be able to do a review till after April 5 when I return from the Philippines
-
I hope it works out for you. I looked at them when I was in the market as well, but could not bring myself to be the guinea pig with one. My biggest concern was the cooling, or lack there of with them and not knowing how well they would hold up. Hope it goes well for you and you can review and save some guys some money in the future.

Well I guess I am going to be your guinea pig. I bought one off of aliexpress last week. $323 and change and it was the one called the Ace Eagle. One of the members on the talon forum bought one and so far has had good luck with it so I decided to try. I'm retired and live on a fixed income and it was going to cost me over $800 for the cheapest shoebox, so I cut corners. I have not had a chance to fill any tanks yet, but just used the plug and run it up a few times. Not very loud and seemed like it might be ok. Two things you do have to do are, 1. use the metal hose clamps to hold the water lines on, wire ties won't do the job. 2. Use a high grade synthetic oil like what they use in the regular scuba compressors. All my research said to do that as it keeps from building up carbon deposits that will kill it. I bought Chemlube 751 to use. I won't be filling any tank over 48 or 62ci and if I need to start out hand pumping a little on the tanks to decrease the run time I will. It's the high pressure over 2k that gets me on the hand pump. Mine is the 220 volt compressor and I had to rig up a connection as their plugs are not like our 220v. Their 220v plug is like our grounded 120v, and the little water pump that comes with it for cooling is 220v also but has just 2 prongs like our 120v. It took all of 4 days to get to my door after it shipped and that's including the 2 days it sat in customs. If you would like the link to the one I bought I can post it, it is the one listed at $170 plus shipping. They will set it for either 30mpa or 40mpa which is either 3k or 5500psi. It's listed as a 6k compressor. You just have to tell them which, I chose the 40mpa because sooner or later I will have a 4500psi tank to fill. I hope this bad weather leaves so I can get out and shoot in order to test it on filling my tank. If you have any questions I will try and answer them. Guinea pig over and out...lol

Bh1976,where did you by the oil and how much? Roger that on the hose clamps. I'm with you on the fixed income. I bought a omega super charger from aoa last year. So far no problems with it. I take my scuba tank to the dive shop have them fill empty tank then I top off with my compressor no sense in over working omega compressor even though it will fill up it to 4500 psi. This compressor look small enough to put it out on my deck to top off air cylinders on the airgun. Judging by the picture with the carry handle looks to be portable. I have a hill pump mkIII, not in bad shape. If I get this one, I'll keep the omega in my basement where I do maintenance on my airguns and keep this one one the deck and if both fail I'll use the hill pump. If the hill pump fails well heck I will just go get my break barrels and just keep shooting 😎 I read and read about the water pump. Did the water pump work or did you have to buy a 110 volt? If so i bet chinamart will have one in the pet dept or flea bay. Yes post the link, don't want you to be the only guinea pig😳😎 also post a link from the talon forum about this compressor.
-
Bh 1976... can you tell our audience how long it takes to fill a airgun cylinder, small cylinder tanks 13, 48 ci. Sure beats a hand pump😳
-
I will be the audience....
-
I've been looking at these things also. I've noticed that there are some things that differ between models. Some have just one "vent block" on the high pressure side. Some have two blocks, one between the first stage and second, and one on the HP side. Seems like having the option to purge moisture between stages might be an advantage. Some of these types are also starting to come with auto shut-off. Then there is the 110v-220v thing to keep in mind!

On fleabay or AliExpress?

I have seen the omega super charger on AliExpress but of course renamed different color made in China so that should not come as a surprise 😳
-
I will be the audience....
I suspect that there is in attendance an audience already 😎
-
I looked through the compressors that AliExpress has listed and it's one heck of a lot however towards the bottom it shows how many sold and the majority of them are (0)

Okay here is the link to the compressor that I bought. And the oil I bought was on Ebay. They sell it by the pint, quart, half gallon, or a gallon. The pump takes right about 14oz and should be changed when it gets dark in color. Since I figure they were just putting regular motor oil in it, I will change mine a little sooner to help flush it out good. They ship it emptied, as it can't go on a plane with oil. They said motor oil or hydraulic oil is ok to use but with all I have read, I will use the synthetic scuba pump oil. It's not cheap by the way. I bought a half gallon of it and was $28 for the half gallon and $15.40 shipping and handling totaling $43.40. But that will be about 3 oil changes after the first fill. Here is a link to the half gallon of oil, and I see the price has gone up since last week, now $30.50+ shipping.
I can't say about the time for filling as of yet, I hope to know a little more this weekend as the weather has been so bad. As of now all I have is my 490cc condor tank, but it won't be too much longer before that changes. I have a tank drop down adapter coming that I had made with 5/8" threads so that it will fit any paintball tank that I want to use. It will be here between the end of this month and the first couple of weeks in April, so by then I should have a tank picked out and a new condor valve ordered and on the way.
Joan, the one replying to me from CHON Electronic where I purchased the pump was good about replying back to me each time I sent a message with a question, although sometimes had to re-clarify what I was wanting to know I had no problems. For the price if all goes well, I saved enough cash to be able to get the other items I want, err, need... ;D
I hope this info helps a little and I will keep any updates posted on here as time goes by. The first link you will have to type in the site aliexpresscom with the h-t-t-p, etc since the site wont let me post a link

Oh and to answer about the little water pump, it works on 220v after I realized it used 220 volt...lol ::)
-
I have been looking at these mini compressors also. Here is another one from the Talon Tunes forum. Its supposed to be one of the more reliable brands. Would be a great alternative to pumping. I would only use it for filling my pcp rifle.

Yeah, I read that on talon also. What made me go with the one I bought was a different thread on Talon. One of the posters there had this to say:
Postby olbluecat » Sun Dec 25, 2016 12:02 pm
Ok a little up date on the compressor , so far it has a little over 55 fills on it and have not had any issues , the oil in it still is water clear and the in line filter is still dry, the humidity is very low and my shop has wood heat so it is very dry air in here will see as the summer comes and it gets very humid here in SC how well the filter works, I think one reason the filter stays dry is that the pressure hose to the gun is mounted on top of the block with pressure release valve on the bottom , not sure time will tell but one thing it sure beats the *(&^ out of hand pumping, I had to buy some new water hoses the ones that came with it had kinks it them and could not get them out but new hoses were abote 2.00
He bought the Ace Eagle and for some reason it sounded like the way to go. I will find out though. There was talk of both of those in this thread and here is the link to it.
wwwtalonairguncom/forum/viewtopic.php?f=1&t=35991&hilit=Ace+Eagle
Oh, and my hoses did not have any kinks. They were curled up nicely, but did have a bunch of styro stuck to them..

Yes there is a minimum of posts before you can post pictures and links. I think it's 10 or 20 so you are close

Thanks, I knew it had to be since there other links on here. But I did not see it written anywhere in the rules when I joined back in 2014. Shows how little I post. But then again, that was a long while back.

Ok folks I drop the dime , ordered one from AliExpress. I ordered the 110 volt. I hope the water pump is 110 volt, otherwise I will have to go to chinamart pet section and buy a pump? The compressor $160 and some change. Shipping $144 and some change. I click on buy it now and the price jumped to $179 and some change. Got the discount coupon $4 and the total shipped was $ 324 and some change. I hope the compressor is package well for the journey across the pond. I will have to wait to open the box after April 5 and test review this littleness compressor. In the mean time bh1976 I await your test results as do our audience 😎
-
Can't wait to hear more. Can't be worse than pumping.
-
kzz1kaw, which one did you buy, the tuxing or one like mine?? As far as shipping, it will be inside styrofoam in a cardboard box that is packaged inside a little wood crate. Although the wood is about maybe 1/4" or less, that is how they ship. One end of my box was partially opened when fedex delivered it. I believe customs probably did that trying to get a peek. Some people have reported damage to theirs, but don't know if same as the Ace Eagle or one of the others and by a different seller.
My M10 is supposed to be delivered tomorrow, so there is a small item to put air into... ;D ;D ;D
See what buying that pump made me do, it made me have to buy another rifle to put air into! :o

The one I bought is called yong heng air pump blue color from Darren trade. Looks like the one on fleabay. There are so many of this style compressors with different names color. Is yours pictured like the one I originally posted same color?
-
I looked at my first post and what do you know it is the same compressor about 100💵 Cheaper buying thru AliExpress. Don't know if is the same vendor. 100 💵 Is 100💵. Just means I can spend the money on airgun related stuff maybe another pcp? Lol this hobby is addicting once you go over to the darkside😳😎. Btw did your compressor come with spare parts seals, o-ring etc?
-
Yes mine came with spare seals, filters, and a test plug. I can't say what all is in the bag but a good handfull of parts. Here is the exact one I got. Just copy it and paste in your browser. All except the first little 4 characters....I can't post a link yet, but I posted a picture on my 3rd or 4th post...lol

I copy an paste. Same compressor except yours has gold anodized pump and 220 volt and the one I ordered is silver 110 volt
-
Bh1976 you said pump came with spares. What is a test plug? Is the water pump a submersible type or not? I'm hoping that the 110 volt pump includes a 110 volt water pump and not a 220 volt pump?
-
If you ordered a 120v compressor, I'm pretty sure you will get 120v water pump. And yes it is submersible that goes into the bottom of your water container. I went to wal mart and bought a 5 gallon bucket with a lid to use. The plug I am talking about is the little plug you can put in the end of the high pressure fill line to test run the compressor and make sure it builds up pressure. It's a little shrader plug. If you scroll down on the page of the one I bought, you will see all the parts it came with.
-
Roger that on the test plug. Last year had to replace my 5 hp pressure washer pump rated a 3000 psi that instruction said to use 30 wt non detergent oil? I'm going to try that for the oil and for the coolant there is a product that you can buy at the auto parts store purple/ violet color additive that you add to the coolant. My omega super charger if I remember correctly I had to add purified water or a bottle of drinking water with the included coolant. Don't remember about the oil don't have the manual to look it up. Maybe some of the members on this site can chime in if you own a omega super charger. Never did understand what the difference is between 110/120 volt thing😳
-
Me either... they both hurt like *&%$ if you put your tongue on them.
-
Never did understand what the difference is between 110/120 volt thing😳
In the U.S. the line voltages are 120 volts now, not 110v. And we have 240 volt and not 220v. I don't know exactly when or why but it did change.
I may see if I can find a higher flow rate water pump to make sure it stays as cool as possible. But of course it would be in 120 volt. I only chose to use the 240 volt because I had already run a line in my room here for some other electronics and had read that it is easier on the pump motor for not drawing as many amps.
-
From what I have seen on these compressors base on pics only and description that if the compressor gets too hot that it shuts off and it has a temp gauge by the on switch. I see pa has the hill pump for 289 shipped. Hmmm hill pump or add a little more cash and take a chance? Ahh I'll take the compressor 😎
-
There is a lot of talk on some of the forums that the G6 pump is better than the Hill pump. But I have an Airforce pump already that I bought with my condor. Talk about a while pumping up the 490cc bottle. Getting to 2k is not so bad, but 3k had to had a little leverage help. Since my health went south and the last surgery I had, I don't have enough weight to make the pump go to 3k. That's one of the reasons for the little electric pump. I know I won't be using it much, so I'm hopeful that it will work ok for me. I did hear one guy had his going to 60C and shutting down. Don't know if he found out the trouble or not. I figure when I go to air up the tank or bottle on the rifle, I will throw in a package of Blue Ice or two to chill the water down and make nice and cold. May even pick up an extra block of Blue Ice since it won't hurt to have spares.
-
The audience and I are waiting for your review
-
Here's what I'm thinking....
This thread has answered some questions and raised some questions. Ultimately questions may still remain that can only be answered here by speculation. BountyHunter has done a great job at answering what he can from his experience. I think the most important information he has given us so far is:
Quote: Joan, the one replying to me from CHON Electronic where I purchased the pump was good about replying back to me each time I sent a message with a question, although sometimes had to re-clarify what I was wanting to know I had no problems. For the price if all goes well, I saved enough cash to be able to get the other items I want, err, need... ;D
End Quote:
A well placed message should clear up any grey areas. I am doing some decision making and comparison shopping myself. My biggest issue here in the deep south is humidity. I think I can all but eliminate that issue by keeping the compressor inside the house in the controlled climate. That negates the option for a booster type compressor. I don't want 2 compressors running in my house. I would like to explore ways to have pressure controlled start up and shut off. A small reservoir air tank. Kick on at 2500 and kick off at 3000. You know.... connect my gun to the reservoir, fill up and walk away. Master shut off when I'm not at home or shooting airguns. Fire it up 30 minutes to an hour before shooting sessions. Seems like a small ninja tank would be plenty. Keep the larger tank filled and at the ready for away games.
-
I should have clarified the 2500 low side..... I don't plan on filling my gun to 3k. I may wish to bump that low side up to 2600 - 2700psi and the high side up to tank capacity.
-
And out of curiosity I sent her a note just a few ago asking if it would be ok to maybe add a desiccant filter to the input of the compressor. I have a couple I bought a while back at harbor freight that I can connect to the input where it just has that little brass filter. If it does not put too much strain trying to draw air through it might really cut down on the water that the pump has to let out. If things were really bad with humidity I'll just turn on one of my portable dehumidifiers that I have setting in a storage room. Hmm, to bad I can feed the air coming out of it directly to the pump...lol
I did a few more test runs with the plug in the line and it does heat up fairly quick, so I will probably go ahead and find a higher flow rate water pump. On amazon they have all different flow rates and pretty cheap too. Now to figure out what the flow rate is on this one that came with it and increase it by at least 50% or more. I do not want it to get hot.
And thanks for all the compliments. I will keep all I can find out posted. The more info the better.
600 l/h is the pump flow

The test is with the test plug in place? Have you tried filling a tank / gun ? I believe the test plug you are referring to is a plug to keep dirt out of the quick connect. I'm thinking the reason it is heating up fairly quick is the test plug on the quick disconnect? This is just my spectulation of course. Try it without the test plug and try filling a tank or airgun and see if it heats up?
Btw... I like your avatar 👍
-
Will get to fill a small tank tomorrow on my new Mrodair M10 when it gets here. It is a 250cc cylinder and fills to 2900psi. And they explain in their videos that it is a test plug and show using it in the vid to check to compressor as they put the plug in and run it up to 5500psi. I guess you could leave it in to keep particles out also, but it is a test plug. Been looking at other pumps and found on ebay also. The 600 l/h is 160gph and the next step up is 290gph and on ebay is $13.75 and free ship. Then a 500gph for $16.95 shipped free, both same seller. There is other on amazon in different sizes for just a little higher. All these are 120 volt and I would have to watch and not plug into my 240 volt power strip or POOF!

Don't understand what they are saying but at least you can see this compressor working. I am going to add ice in my bucket along with a clip on fan blowing on the cylinder head to help keep it cool. Heat is a killer on the compressor just my 2 cents. Draw your conclusions from the video. I'm in😎

I've had my eye on this one: http://mylondair.com/product/html/?106.html (http://mylondair.com/product/html/?106.html)]http://mylondair.com/product/html/?106.html
I'm not sure about the price yet but they claim it will fill a 6.8L bottle. For now, I only plan to fill my AT44 directly but may buy a SCBA tank in the future.

Interested in the review of the compressor as well.

kzz1kaw I am interested in getting a decent compressor eventually, both my SCBA tanks I can get filled to 4.5K at a dive shop near me however they both expire permanently in Dec 2019, and Terry (the owner of the dive shop) told me that the tanks in the condition that they are would probably last a very long time even after the expiration date. A while back I seen where some of the expiration dates of the carbon fiber tanks could be extended but when I talked with Terry he said that's for government agencies only (like the navy) and doesn't apply to the public (ain't that a raw deal). I'll be keeping an eye out for a good compressor deal myself, there's so many of the Chinese compressors out there now it's crazy and I'm a skeptic on their quality.
I noticed in your signature that you were 11bravo, I trained in Ft Polk myself, I had some wild times in Leesville Louisiana during my short stint there ;D

Wayne I hear ya about the compressors. Roll of the dice as they say😳 The way I see it is it's a $300 compressor. If I get a year out of the compressor that would be money well spent. If not well I didn't spend that much on it and chalk it up as a loss and move on. To me it is a gamble I'm willing to take. Just like in the military when we go outside the wire it's the roll of the dice and hope you don't roll snake eyes per say same with this compressor. You either get a good one or you don't. As for 11b....ooah! Btw I notice you are from Kalamazoo. Are you a member of the swmgc?

Mylond Air no longer sells on AliExpress so the MV-4L model isn't available there. I have had my eye on these two other compressors on AliExpress. One of them has auto shutoff and the other has auto shutoff and auto air release but they do cost more with those functions.

You have to specify when you place your order 110 or 220
-
Ken I'm not a member of the club, have thought about it is all.
-
None of the plugs match my US 220V outlet so I'll have to cut theirs off and replace it with the proper plug. It looks like they have the correct plug for US 120V.

Ken I'm not a member of the club, have thought about it is all.
Hope to see you out there. May is when the guys move from indoor range to the outdoor range. Fun shoot and field target. Every Saturday 10:00am. I will be there most every Saturday. I will send you my contact info via email.

Oh boy, Oh boy, Oh boy.. ;D ;D ;D...If this little comp continues like it just did I am going to be a very happy camper. I had about 8mpa in the M10 where I had put a little air in it last nite, so had to top off and bring up to 2900psi/20mpa or so. It took maybe 3 minutes or less. I know I should have timed it but was too busy watching the gauge and finger on the off switch. Then I topped off my condor tank which was down to about 2500psi from 3k and it took about the same time, NOT VERY LONG! And no workout and stress. And I am going back out to shoot the M10 some more and it does like the 28.5 Eunjins. Also the 28.6 Big boys, however it really did not do to good with the 14.3 crossmans from wally. But with 12 to 13 mpa on the gauge, it was shooting the 28.5 Eunjins at about 859fps. When down to about 8mpa I put the 14.3gr in and it hit 965fps. I was shooting at about 25 yards and I am happy with the results after getting the scope zeroed. Will keep this updated if any changes.
Edit: Topped M10 back up from about 8mpa to 20mpa and the time was only around 2 minutes or less. Did not get real accurate due to the fact I stopped it a shy bit before full and bled the air down and realized it so closed valve back off and turned back on for may be 10 seconds. It is heart attack prevention for people like me. ;D

That link is even a better deal than the one I ordered😳 I like the 12v compressor even the bigger compressor v twin cylinder $1000 ship. Hey that compressor is sold in the u.s. But rebranded costing more hmm😳😎
-
Got the $300 in my cart just waiting to sell one more gun to fund it.

Iam looking at the one listed on ebay but going thru Ali the Model number is YH02JZ , what o u think the difference is between the pump u r looking at and this one.
-
Sorry, I couldn't tell you, I can't read French or what ever language that is on that site. I do see it says 110/220. Other than that... no idea.
-

One thing I did notice when considering which one I wanted is they had one that looked the same but was a little bit cheaper. It was priced lower because the cheaper one did not come with the filter on the end of the fill line. My model number is YP02DYS and has the filter, and the model number that did not have it is YP01BDYS. So I chose to make sure I ordered the one with the filter. I think they need all the filtering you can get for them. I don't know if it will hurt but I'm going to add a desiccant filter to the air intake on mine. I say just read carefully before you hit the buy button.

It looks a lot like the Alpha Carette compressor I would agree. Whoever wrote up the information can not put a English sentence together very well, but the pictures look like it's the same unit. Maybe these are the ones that Mrodair was supposed to get and ended up pulling out because there was a dispute between them and airtanks about the quality of the Mrodair units. If you look on Mrodair's website it reads that they decided not to carry that one due to a dispute, but they were pretty hot to trot to sell them last year. Interesting find. I'm glad I went with the Omega supercharger though. I know it was much more expensive than the ones you guys are looking at here, but it performs well and it has been on the market for awhile and has great reviews from owners. I know not everyone can afford one in that price range, it was out of mine range too, but I sold a gun to make up the difference just to have the piece of mind.

Ahhh.....hmmmmm..... I too have the omega compressor. I am trying to find the clone of the omega I saw on AliExpress that I found last year. Looks identical to the omega just a different name and cheaper😳I am going to find it and post a link😡😳
-
I knew when I talked to aoa about the omega compressor than it was made in China to their specs😳Ooooook😳 After I received mine is when I went to AliExpress and found the omega compressor just rebranded😎😳. So I think most of the compressors are made in China ? No ? I don't know but what I see on AliExpress. I'm sure there are other sites to go to in China that make pcp compressors 2017 is a great year for pcp compressors from cheap to the more expensive ones😳😎 I'm buying a smaller unit in this post so I can fill my pcp airguns or my small tanks I have on my deck while shooting or in my polbarn sniping starlings chipmunks. unlike the omega I have It's not Portable, heavy. I use it to top off my scuba tanks guppy tank. The omega will fill an empty scuba tank not this portable compressor. This smaller compact compressor will make a great addition and versatility of my compressor collection to feed my pcp rifles....... welcome to the Dark Side😳 boys and girls

Price on Aliexpress are still buffed wayyy up. And yes, most compressors are made in china, just like iPhones.
-
I am certain my omega was made in china, there is Chinese writing all over the outside of the box. The main reason I went with the omega was because it was proven and the supercharger had some upgrades I wanted such as the auto drain on the water capture and an hour meter, both things that could be added with aftermarket parts, but this way I didn't have to do it. It is a heavy bugger no doubt about it, but there is a nice carry handle on the top which makes it easier to carry around, but I wouldn't want to carry it around too much :o It is definitely the best time to get into pcp airguns with all the new systems that are coming out to fill them. I certainly don't miss pumping with a hand pump.

Found a similar omega super charger minus the auto water removal on the back side minus the carbon look decals no price have to contact seller. I found a baur copy. Wonder if the British are using China to make their compressor 😳

Next time I visit the dive shop I'll ask him what brand his compressor is.

Sure does but Joe will say it's a knock off. ::) Better hurry, hurry, hurry and get one from him (IF he has any yet) 'cause according to that link it'll be $1859.00 in 10 more days! ::) Couldn't help myself, his site kills me! ;)

Bh1976...how is the compressor working out for you so far?
So far great. I just use it for now to top off my rifles and it sure is awesome to come in and fire it up and less than 2 minutes have it back up to full. I saw a quote on network54 where someone said they have been working on wearing out one of the little cheap chinese compressors and that has been for over two years now. I hope I have the luck he has. For me when it only runs less than two minutes at a time there is no strain on it. Plus right now just going up to 3k which is about half of what it can do. I think with proper care it should last a long time.

You should get the compressor roughly 9 days after you placed the order online, at least It was for me. I placed the order on 2/26 and they shipped it on 3/1 and it arrived on 3/7. Sat in customs in Memphis, Tn for two days in that time frame. Keep checking the tracking on it.

That is good news! I have the omega super charger. It is nice compressor no doubt. It is good to fill an empty scuba tank and topping off tanks. But for my needs topping off a scuba tank or a small guppy tank to topping off the airgun, this compressor is versatile. Carrying handle (has to be lighter than my omega) bucket of water, electrical outlet and spend the days shooting 😎
-
Well if shipping goes like yours 1976 should have pump here by 1st couple days of April. Will be using it like you are using yours no big tanks just topping off rifles. Hope i have as good luck as u are having. I know it will be better than hand pumping
-
I'm following along with progress on this. I have been looking at these China pumps for a while. Have not pulled the trigger because I worry about quality. Will be very interesting to keep up with input from those that have bought them.
-
I think I'm going to go in a different direction here for a bit. I think I am going to pull the Trapmaster off the classifieds. I spoke to my Scuba guru, Mr. George at Sea Divers. He said he would sell me another 3300 psi 100cf Alum tank with fresh hydro/visual and filled plus refill the one I have now for $110. I think I might hold off on a Chinese compressor until more people review and report on them. I'll cascade my tanks and go from there. I only fill "SynBad" to 2600 - 2700 and the paintball field is 8 miles down the road for refills between inspections. I've also heard of some guys feeding these booster compressors with cascaded and regulated tanks. That's another avenue I want to explore. That's the way they do it at our local Fire Dept.

You lost me with this? Care to eliborate on this?
-
Sure...
At our FD they have a series of cylinders cascaded. These are regulated to low pressure and feed a booster that fill their breathing tanks. So, if I have my 100 cf tanks filled at the scuba shop with clean dry air and cascade them regulated at ... say... 90 psi. Feed that into a booster like the Altaros....
Follow me?

Ok roger that. I did see a post somewhere don't know if it is on this site or another about the altars booster. Interesting.
-
TerryH has one and loves it. He supplies his with a shop compressor and has gone to lengths to keep water out. With this idea it would be dry air in and dry air out. Not only that, this air comes from a dive shop. It's clean breathable air. No noisy compressor running and sucking on the electric bill.
I might be talking out my earhole but I'm going to look into it.
-
I was checking out the videos and threads on the boosters, I've also been thinking about building one with a big brake cylinder, the guys are doing it, some are even building their own big custom cylinders with great success, it's really neat making 4500psi from 3000psi for example.
-
lol.... 3000 to make 4500 to fill 3000 to make 4500...
-
I think I'm going to go in a different direction here for a bit. I think I am going to pull the Trapmaster off the classifieds. I spoke to my Scuba guru, Mr. George at Sea Divers. He said he would sell me another 3300 psi 100cf Alum tank with fresh hydro/visual and filled plus refill the one I have now for $110. I think I might hold off on a Chinese compressor until more people review and report on them. I'll cascade my tanks and go from there. I only fill "SynBad" to 2600 - 2700 and the paintball field is 8 miles down the road for refills between inspections. I've also heard of some guys feeding these booster compressors with cascaded and regulated tanks. That's another avenue I want to explore. That's the way they do it at our local Fire Dept.
Good idea! But are you sure the cost of the Altaros and another cylinder would cover the cost of more trips to the scuba shop?
-
Nope.... that's why I said it was something I will look into. For now I will have 2 tanks... half the trips to the scuba shop. And none through customs.
-
Conventional booster system uses shop air to drive the booster around 100-130psi then connect your hpa tank to the booster high side 500psi and up and the booster bumps that in to your high pressure tank you want to fill.
More psi you have in the tank before the hpa piston the quicker the other tank will fill.
Usually the pressure ratio is 50:1 in modern boosters. With 100psi shop air you can get 5000psi from the hpa side.
So you can drive it from a tank but it takes a lot of air, like the altaros. But the higher the feed on hpa side the less drive air you need, and on my booster around 1000psi is the comfort point, after that it starts to take too long.

Right, so take 2 100cf 3000psi sources regulated at 90 to 120 psi (in place of shop compressor) and feed the booster. Now, I'm not topping a tank off... I'm filling my gun from 2000 to 3000 as needed. How long would the source tanks last?
-
If I just fill my gun from the 100cf 3300 psi tank from 2000 to 3000 when my tank reaches 3000 I'm done. But regulated to 90 psi to feed the booster I have usable air in the tank until it bottoms at 90 psi.... right?

So is there any consensus on which compressor is good, or are they all relatively equal? I see the Yong Heng and Ace Eagle mentioned. Personally, I'd prefer 120V and plenty of rebuild parts. Also what oil would be best? Would either of these hook up to an Air Venturi tank directly without any additional parts? Thanks.

Yep, he's done it..... thanks
Only difference is, he's driving the booster with air. That uses a good amount of your source. In the case of the Altaros, a motor drives the pump. Now all of your source air is used for filling.
-
I just started the process to order a Tuxing 110v compressor today. Should take something just over two weeks to receive. I read quite a bit about them on what I recall was the Talon forum-seems the gentleman known as Wingman from New Zealand has had one for quite some time (I believe he uses 220 common in NZ) and he stated he has been very impressed with it's function and even used it once to fill a dive tank from empty over several running periods with cooling time between. Probably always a gamble with stuff from China but they seem to be getting better. We'll see.
-

I think the Altaros uses air, the Shoebox uses motor. Could be wrong though.
-
TerryH would know, he has one.
-

Robert you are correct. The Shoebox has an electric motor and belt to power the booster. The Altaros needs an air source to power it's booster. The Altaros does use very little electricity but only to work it's controller electronics, switches etc.

I ordered the yong heng as I suspect they are made in the same factory under different names colors. I have been in contact with the seller about spare parts if I should need any and the resond was that parts are readily available?😳 Hmm hope it does not need any parts. Time will tell as I will be using this compressor more often than the omega. Omega as a backup compressor. Good to have options 😊 I am usually it my clubs range on Saturday shooting and I will have my guppy tank to fill off. This compressor will be topping off the tank and during the week I'm shooting from my deck or pole barn. So this compressor will no doubt be used more often plus my spouse wants to shoot which translate to being able to purchase more airguns😎 As far as oil I am going to use 30wt non detergent oil. Had to replace a water pump on my pressure washer and it was recommended to that oil so that is what I will try. I know the omega came with the required oil but I don't know what it is. Maybe someone who had a omega compressor can chime in on the oil? I can find out but at this point I will try the non detergent oil.
-
I also ordered the Yong Heng Pump, on the description it says 5W40 motor oil or hm-il 46 hydraulic oil. In looking it will be easier to get 5w40 .I think I will use synthetic. Ordered pump on the 22nd and according to fed ex pump should be here on the 29th. have my fingers crossed.
-
I've read elsewhere that regular motor oil may cause carbon deposits and possible problems with these compressors but mine has just been ordered (Tuxing) so I have no direct experience. Several recommendations were noted to use Coltri or Bauer compressor oil or something called Chemlube 751 to maximize compressor life and minimize problems. I bookmarked the Chemlube on my other computer as available either on Amazon or Ebay but I can't recall which.
Just checked-Chemlube 751 $57 per gallon on Amazon and 1/2 gallon available for just over $30. I would assume any compressor supplier could supply the Bauer oil. Motor oil might work just fine too.
-
I wouldn't use motor oil in a hpa compressor for the risk of dieseling and ruin seals. No point on going to save couple of dollars on oil when you are going to buy a compressor to fill your guns worth hundreds or thousands of dollars.
Any ISO VG 195 compressor oil should be used, Bauer or Coltri, later being a bit cheaper. Liter costs like 20$ and you are using 300ml per oil change. You get better lubricative qualities and no carbon buildup to ruin the seals, so why on earth anyone would use motor oil?

I hear ya Wayne... pretty much where I'm at. At least I now have 2 tanks to cut the number of trips in half.

It's costs me $12 per fill at the dive shop here and I gladly pay it. I mean, someone's got to help them pay for the indoor heated pool they have there! For that $12 I get a tank of clean air with no worries about oil or water contamination. I don't have the time or energy to maintain a compressor properly.
Someone may have mentioned it already and I just missed it, but seriously consider a good moisture filter with the compressor. Water corrodes the aluminum liner of the tank and this process is accelerated when under high pressure.

I should have mention that I do have a diablo air filter that I bought for the omega compressor from r l Airguns. Being that it is quick disconnect from the output line, I can use it with this compressor as an added moisture protection.

Hope to see you at the outdoor range on a Saturday beginning in may or the last indoor shoot April 9 downtown Kalamazoo. Pm me if you do decide to. I'm even extending an invite to my place being I have an outdoor range that I shoot at. Air is free and you can see it up Close 😎

Well that was fast, just checked tracking on pcp pump and its out for delivery today . Hope it works as well as the delivery system. :D

Found a video on you tube from wingman115 on a yong heng paintball mini compressor. Same one that arrive from china yesterday😎 https://youtu.be/kp5pIT3kjqs I won't be able to do a review till after April 5. Check out the video
-
Will be interesting to see how quick it wears out with hydraulic oil in the unit.
And when do we start to see exploding carbon tanks due to corrosion in the aluminum liners.
Dryers mandatory, and I'm not joking guys and girls.
High pressure environment speeds up corrosion big time.
Other than that safety lecture, looks ok if it works more than couple of fills.

Just filled my Air Venturi 90Ci tank from mt . Everything went fine. I stopped at 2000 psi to add more water to cooling bucket and let the AV tank cool dwn i. In checking temp on compressor the highest it reached was 119 degrees on pump. Total time with adding water and cool dwn was approximately 25 min. I went with what the manufacturer stated AW ISO 46 Hydraulic Fluid, in checking this type of fluid is used in high pressure pumps. On first time use all went well, it does produce heat so keep a close eye on cooling water .
-
High pressure hydraulic pumps I recon? What surface load and bearing speeds are we talking about?
Seriously hydraulic oil is not compressor oil, and less so for high speed compressor.
Each to his own but there are oils more suited for the task. And that is all measured in equipment life what you use.

Received mine last week and I plan on doing a review video of the compressor. Mine is a yong heng compressor blue one. Already filled a 13 ci bottle empty in less than 5 minutes. Stand by for more info.
-
For those of you considering this compressor, in the manual it states it does use hydraulic fluid number 46.
-
What says in the chinese manual, if you must believe that you can go by that or use proper high pressure compressor oil and be sure its suited to hpa use. Might even lubricate better and not combust.

I recently bought a Tuxing comp from aliexpress and I'm using Chemlube 751 as it's designed for reciprocating piston HPA compressors. I'm also using water and a "water wetter" in my cooling bucket. I haven't been able to test it too much yet. My tank comes tomorrow and my moisture indicator comes Friday.

Congrats,how did you come to the conclusion to use chemlube 751? Does your compressor manual also states to use hydrolic fluid # 46
-
There are many diffrent manuals and oil recommedations in them, from hydraulic fluid to engine oil. But then there are real compressor oils out there, why would you not use them to expand the service life of your machine?
Do a little comparison of lubricating properties and flamepoint on diffrent oils and make your own conclusion what to use.
These comps dont have conrod bearings just the aluminum of the rod is used as a bearing surface, so give it the best oil you can.
Just my 2C
Marko
-
Ken,
I never received a manual for my compressor but the 751 is designed for this application and has a high flashpoint. I believe Chemlube 501 will also work as it is very similar but a little thinner I believe. I think I bought ISO 150.
-
If the manufacturer recommends a certain type oil and you choose not to use it wouldn't that affect any kind of warranty?
-
If the manufacturer knows anything about standards he or she will give you the minimum requirements for the lubrication needed.
Marko
-

Good question. All I know is what is printed in the manual. Now if one wants to try a better oil such as chemlube 751 and it can be used for hpa applications, I say go for it. Might prove to be beneficial to the longevity of the pump
-
I just know that it's becoming more common practice for companies to try to wiggle out of warranty replacements these days.
-

Marko
Not the case here obviously... the manual states #46.
-
Ok, I'm not here to argue, this is my first point.
But I have been servicing indusrial machines for long time in the past. Hydraulic oil is ment for carrying load, to transfer it. Its not the kind of oil you use in a reprocative enviroment. Its main goal is to equalize heat throuhg the system, and keep it clean, there are detergant qualities in the fluid. And additives to lube the pumps.
The Iso vg rating is for viscocity of the oils not lubricative property, and i think the chinese translate the oil wrong.
You can have iso vg 46 hydraulic fluid, and you have
Iso vg 46 compressor oil, it tells you only the viscosity at diffrent temps.
Compressor oil has higher flash point and lubricative qualities, and additives to form a good oil film between bearing surfaces.
Check things out and dont use the wrong oil.
Marko
-
Point taken..
My question was only concerning warranty. No argument here.
-
The seller I bought from offers all sorts of replacement parts. I'd rather buy those than attemping to ship back a 50lb unit. Shipping was $150 alone. Everything inside it looked like parts would be fairly easy to source as well.
-
I agree with what Marko is saying. Right kind of oil for the right kind of application, viscosity is important I think. I wouldn't use regular engine oil in a pcp compressor myself.

There is no proper water separator, you'll be bleeding it off like every 5-10min. And there's no dryingmedia so you'll need an external molecularsieve filter on the high side.
I wouldn't use it for large tanks but everyone does the best they see fit.
Will it fill a large tank, yes maybe, will it survive that in a long term use is anyones guess.
Heat is the main problem, getting that away from the oil. Run and let it cool to ambient run again.
Buy a good filter and separator. Then try and see what gives first.

This one (MSV-4L) from Mylondair claims to be 3 stage and fill up to a 6.8L bottle: http://mylondair.com/product/html/?106.html (http://mylondair.com/product/html/?106.html)
It really doesn't look any different than the other small Chinese compressors that they and others are selling so I'm not sure that the specs are valid. I was quoted a price of $250 + $115 shipping to my door.

Mine doesn't have a separator or drier. I don't mind purging water every few minutes and I'm going to make something to hold the sieve before the indicator.

Remember to do it properly, you are designing hpa filter for pulsed duty cycle, 0-4500psi so safety factor needs to be high enough. 3.5:1 atleast. Make it too weak and you have a pipebomb on your hands.
That mylondair is not 3 stage for sure, where do you put the third stage?

Mine came with a "filter". Pretty much a tampon in an aluminum tube. I've taken it up to 4k PSI and it holds well. I have to measure the wall thickness but I'm going to guess it's near 1/4". My thought was to get a tight fitting piece of PVC and pack that with sieve. The aluminum will reinforce the PVC while also making it removable so I can put the media in and pack it. I'm going to take it into work tonight to measure and see what materials I can find that might be better than the PVC idea.
-
The only difference that I can see between the Mylondair and others is that the Mylondair MSV-4L is running at 3800 RPM if their specs are correct. I certainly don't see 3 stages. Maybe I'll have to buy one to find out for sure.
My Chinese hand pump came with a similar filter and the tampon has yet to see any oil or water contamination. So, either their isn't any contamination or the tampon is not filtering it. It seems to be a very dense/absorbent material so I would expect it to trap something.

Having one of these chinese pumps I can tell you that some of the specs on Mylondair seem to me to be doubtful. First off, There is no doubt in my mind that given enough time and running cycle, a 6.8l tank could be filled. However this would take a long time and multiple sessions if you wanted your pump and tank to be treated with the kind of respect HPA requires. Unless they redefine what a stage is, there are only 2 compression stages. There is a typical piston found on basically every reciprocating air compressor ever with a second piston that looks to be brass riding atop the 1st stage piston. That second stage has the water cooling jacket. The device in the middle of the 1st stage and the second stage is an area for oil/water to accumulate in an attempt to keep it from getting to the 2nd stage. The device on the right side of the unit is the same thing for post 2nd stage. Thus the bleeders at the bottom. My compressor like the msv-q4 has the same thing going on in the larger head atop the 1st stage thus why I bleed both during operation at a frequency of about 1.5-2 minutes. Trust me, quite a bit of moisture is condensed out of the air during the process so it is important to do it often as to keep the "reservoir" from filling up. Last the RPM of the motor is very likely not 3800rpm. The maximum speed of an electric motor, also known as syncronous speed, is governed by the function MaxRPM=(120*Frequency in hertz)/Number of poles. Since you must have an even number of poles, IE north and south magnetic polarity, you'll find that a motor running at the 50hz they are supplied is only capable of maximum speeds of 3000rpm. But you'll never see those speeds or else the motor would produce no torque and it is the torque that does the compressing. That is why some of the other models show 2800rpm, that is a more realistic speed once the slip of the motor is taken into account. No slip, No torque. Physics is what it is. It is the same reason you'll see your bench grinder probably showing 3200rpm ish. 60hz on a 2 pole motor gives 3600rpm max, factoring in slip you'll get the rated rpm.
All in all, these compressors are good for what they are but the claims on the MSV-4L aren't adding up to me. If anyone chooses to get one of these compressors, understand that they must be babied as they just are not designed as well the big names like bauer, coltri, carrette, and omega but they can get the job done.
-
Jeremy,
Great explanation. The specs didn't add up for me either.
-
So what size tanks are these compressors meant for filling on a regular basis ?
-
I see specs from 1.5L to 3L ?
-
Hi All,
I have a question about the water accumulation and the bleeding every 5 - 10 minutes. What happens if for some reason you get distracted and don't bleed the water?
Will the water accumulate and cause the compressor to hydro lock and damage the piston, rods etc. like an internal combustion engine?
Thanks,
Taso

2L is the highest I would go personally but everyone is different.
The compressor won't hydro lock because of it's design. The valves won't allow that. You don't want that in your gun though. I won't go into details here as they are well known and available in many other places. You should not operate this pump unsupervised without timers timings. It is better to shut off under pressure if an emergency happens rather than to let it keep on chugging along for indefinite amounts of time with no supervision.

This is my overview of the yong heng compressor video on you tube. I was filling a 144cc suba tank in stages. First stage empty was 30 minutes plus 5 minutes that didn't get timed = 35 minutes. Second stage to 4500 psi = 46 minutes. I don't recommend filling a large scuba tank all though this compressor will fill the tank, I recommend doing it in stages. This compressor is good for filling an empty airgun cylinder or topping off a tank from 1k to 3 k or 3 k to 4.5 k. Yes I would recommend buying one😎

During the fill process, I experimented with ice packs in the bucket of water which help bring the water temperature down for the air pump. Approximate fill time in stages for 144 cc tank is 81 minutes +/- 5

Any more reviews on how these compressors are holding up?

I have been using this compressor since my last review with no problems at all. Glad I bought one👍🏾

Ken,
What is a 144 CC tank? That seems tiny to me since a 13ci ninja is 213cc.
I'm considering one of these to top off my scuba after each shooting session (3000 PSI 80 CF, maybe ~200 psi top off) but if it takes an hour to fill a bottle half the size of a ninja bottle, that might not be quite enough....

Good question. That is what it says on the tank. It is a large tank though. It took over an hour to fill from empty. filling a tank from 2000 psi will not take an hour. Hope this helps
-
Is it like a 30 minute or a 45 minute type tank? I found a relevant discussion here (http://www.gatewaytoairguns.org/GTA/index.php?topic=46196.msg435092#msg435092)mentioning the 144cc, I'm thinking that might explain it?
Even if it's a 30 minute, that is still fairly impressive for such a small pump, though I believe I'd want a high pressure side filter if I go this route and that would probably add a fair bit of time to the fill process.
-
I have the Tuxing with a little over an hour and a half run time on it so far. I've filled my marauder a couple times and completely filled a Guppy tank. Impressions are good but it isn't a plug and go compressor.
Anyone buying one should un screw EVERYTHING that screws to the outside and Teflon tape the threads. At 2000+ PSI a small leak may be imperceptible but it's definitely reflected on fill times.
A set of metric allen keys is a must.
A high side separator/drier is a good idea. Mine tends to purge quite a bit of water and I don't trust the tampon filter.
You can't boost the inlet from a shop compressor. It stalls the motor.
My plastic fan on the back of the motor walked itself into the mounting frame and started to shred itself. It's only held in place with some C clips and there isn't a grove on both sides of the motor shaft to retain it.
Also all the screws are a soft material. I plan on picking up some that are a bit harder.
All in all I'm happy with my purchase. Does anyone know where I can get a fairly inexpensive high side filter?

Bought a diablo air filter from r&l airuns $179

I have been corresponding with a seller Chon electronic technologies on aliexpress about the yong heng. I have asked about upgrading the oil/water separator to a larger one. The said they could upgrade to the large one for addition $80. I don't have a tank yet so I would be using it to direct fill my Marauder for now. I just haven't convinced myself to order one yet. This would be about $450 with the shipping. I just worried about how long these will last.

Yes it is the roll of the dice. My omega super charger is made in China along with other name branded compressors. I am using this compressor almost every day filling just my airguns because it is portable. I don't need a tank to fill up. I just fill the gun. My omega is sitting as a backup and no it's not for sale😎

The important part of the high pressure moisture filters is that they are strong enough to handle the pressure as they will need to withstand up to 4500 psi in most cases. I have the Diablo filter and the wall of that filter is around one inch thick or more. It is built very stout to withstand those kind of pressures. This is not an area you want to go on the cheap with as a failure in that part of your system would be a bad day for you or anyone in the immediate area.

I just ordered one of the Xin Yong Shi filters on the 15th and it is scheduled for delivery on the 24th. My hand pumps are their brand and they also arrived quickly and have been flawless. I plan to cut the tampon into two pieces to use on the ends and fill the middle with desiccant beads. It may require a PVC liner of some kind to keep the desiccant from contacting and eating away at the aluminum housing. I think the Diablo filter uses molecular sieve type desiccant. Does anyone know if the Diablo has a liner inside?

No liner just the housing

I have one of the Chinese filters that I did what elguapo99 did by cutting the tampon to about a 2 inch length and bought one of those thin vinyl cutting boards from wally world and cut it so it was about an inch or so to wide when rolled up inside the filter. Then cut the length down to where it is just a hair longer than the inside the filter when the end caps are screwed on so it buts up to the threads on the caps snuggly to form a good seal. Then taped the liner up on the length with tape while it was rolled up inside the tube to allow it to expand to the diameter of the ID of the tube so after each end was taped to retain the round size it was taped the full length to seal it from the filter walls.
I then put one of the tampons in one end of the liner while its in the filter and installed one cap. then filled the liner with 13X molecular sieve medium to 2 inches from the end of the liner and tamped the medium down a few times to settle it and pack it tight without crushing the beads. Then install the other tampon and end cap and place in the high side line.
You do not want the moisture and sieve medium contacting the walls of the filter since in HPA use it will corrode the inside of the filter just like it will a HPA tank. You must use some form of liner inside the filter.
Been following this thread since I have a shoebox now but looking for a faster way to fill my 45 minute SCBA and 90 CI buddy bottle as well as several bottled guns. I like what I am seeing and hearing so far about these small compressors and since I already take cycles in my filling to let the shoebox rest when filling my tanks. It will be no change with the Chinese compressors except for less breaks to full tanks.

Mike do you have the cloned of the diabolo dry air system? If I'm reading your post correctly, you emptied out the little round balls. Btw very little discoloration when I emptied them into a bowl. You bought the vinyl cutting boards cut to length and stuck it inside the cannister right then readied the dryer balls back into the filter right? If so I'm going to buy some vinyl cutting boards. I'll have to check with the wife if she has and old one.
-
Are the dryer balls call a seive right?
-
Mike,
Thanks for the great info.
I don't dare cut up one of my wife's vinyl cutting boards so I need to make a trip to Wally World.
Where did you buy your molecular sieve media?
Did you buy the blue indicating type?
How much media does it take to fill the filter?
Thanks in advance for the info,
Bob

Yes I bought the Chinese clone filter for 60 bucks linked to below. The filter comes with two long paper type filters that are the full length of the filter. I wanted to have the paper material at each end with the molecular sieve medium captured by the paper material at each end so it does not migrate out into my tanks or guns. I have yet to open and inspect the sieve medium ( this is the little balls that absorb the moisture ) which is 13 X grading which is better for moisture absorption than the 3/4/5A graded medium. The 3/4/5A medium is more for other gasses than air and H2O and since I use a shoebox with an oil free compressor for the first stage I do not need to capture any other gasses besides H2O only and is why I chose 13X grade. Research "Molecular Sieve". The cutting board was an old one the wife had and is about 1/16" thick by 16x20 "or so in size, enough to make several more liners. The medium I bought from the ebay link below is 3 pounds that has been reclaimed professionally and bagged up in air tight pouches so its more than enough to for the rest of my life in my compressors filters. It has white and bluish/purple beads so I believe the bluish/purple beads will change with moisture absorption but have not confirmed it yet. Of the three pounds bought it only took about a 1/4 of the 3 pounds bought so the rest is in the "Ball" air tight canning jars with the red sealing type lids.
Before I installed my HPA filter in the line before then tanks or gun I would get a moisture vapor mist out of the bleed valve when bleeding off the guns or tanks. Now after the filter there is no moisture mist or anything except air being released in the bleed off so it is capturing the moisture. .
Hope this helps.

Great idea on the cutting board. I was thinking PVC pipe so I could put an o ring on either side to seal. Cutting board sounds much easier.

I am sad to report my tuxing is already capping the bed. Tripping overloads after about 60 seconds or less of load time. Really upsetting me at the moment but I haven't had time to really troubleshoot it yet.

Sorry to hear yours isn't working😟 Can you provide more details as to what happened? How long have you owned the compressor. How many fills. lubricant used in the compressor etc. I'm hoping it is not serious.

I'm sorry to hear that. Please keep us updated on the progress when you get around to diagnosing it. Mine sometimes won't start from a stop and will trip off after a couple seconds. After a few times of flipping the switch it will go though. Seeing as these are so cheap, I'm sure it's using an AC motor with brushes. Maybe the brushes got messed up our are hanging up.

Yes please let us know what you find as the problem so we all can benefit from the information.

I received my Xin Yong Shi filter ahead of schedule and in record time from China (ordered on the 15th, delivered on the 21st). I have to say that this thing is built like a tank. My 13x MS desiccant should be here tomorrow. Now I'm off to Wally World to buy the vinyl cutting board to use as a liner.

Yea I believe the filter housing is plenty strong enough to hold 4500 psi without issues. I am sure you will be happy with it if you fill it with the MS and paper filter as I did with the liner. Just filled my bottles and guns yesterday with the humidity at 90% with rain on the way and after every fill on the bleed off there was no water vapor seen at all. Total run time for my shoebox was 4:30 hours. The on/off valve after the HPA filter worked perfect to keep from having to build pressure back in the filter after bleeding of from a fill. Closing the valve after the filter and only bleeding off the gun or tanks line to the valve cut filling time considerable since it takes about 10 to 15 minutes to fill the filter to 3000 psi after bleeding off. This way only bleed the whole system once after filling for the day plus allows check for any leaks with system pressurized and valve closed at 4500 psi after tank fill, just let sit for 5 minutes and see if gauge is still where you left it.

Well it's been a while since I have given an update on my Ace Eagle, and am sad to say having an issue. Not a real bad issue, but have been in contact with the company. It may or may not have been that way since the beginning since I just found out. Mine is running too hot. When I started using I only had to run it maybe 30-45 seconds to top off my gun, never from empty. I got in my paintball tank, my drop down adapter I had made by an ebay seller and put all together. I put about 1500psi in with my hand pump first as I did not want to try it on a 48cu tank empty. But I discovered that after about 3 minutes of run time it will hit 65C on the temp gauge. The instructions that they emailed me has listed do not go over 70C. So I shut it off to let cool, bled the pressure. Only after about 5 minutes or so it is back down where I could run again. So after 1 or 2 more times I had my 3k in it. And just my luck, when I went to bleed the air, it kept letting the air out. Not the fault of the compressor though. It was the fill valve on a brand new condor Hi-flow valve that stuck open, and that reminds me I still need to call AirForce about that problem. So had to start from scratch. I used the fill port that was on the drop down adapter and after 3-4 shut down and cool sessions I had my 3k back. But now have some very small leaks to get stopped on the adapter fill port and gauge.
I am using Chemlube 751, I am using a 5 gallon bucket full of water, I put 2 large frozen Blue Ice blocks in the water before ever running the pump again, chilling the water down. I turned the water pump on and it chilled the pump down to 19C before turning on and in 3 minutes or so it still hit 67C.
The last answer back from Joan Shi, the contact person, told me just don't go over 80C. That's freakin hot. I just replied back to her with a copy of the wording of the instructions that she sent me, on the temp and told her that if I go that high and it breaks, is she going to send me a new one. I will most likely get an email reply sometime tonight.
I will post here what she says. It is still filling fine, but I just don't like it running that hot. I can't understand why it is running hot so quickly. But have ordered two new water pumps from ebay that are a lot higher gpm than the one the pump came with to see if that will help. One of the pumps is due to be here tomorrow, it is 500gpm and the one that came with the Ace Eagle is only 160gpm.
-
Allan,
Is it possible that you may have air in the cylinder water jacket or whatever it's called? Is there any way to bleed out air if it gets trapped in there?
Are both cylinders running hot?
Do you have a way to verify the temp sensor is correct? Maybe a infrared thermal gun?
I don't have one of these compressors so I'm just throwing ideas out there hoping to help. :)
Taso
-
You may need to be cautious about using a water pump that has to high a GPM rating since it could cause the hoses to blow off the cylinders or pump if the water does not flow well enough thru the small hoses or it may not help cooling at all since it may be pumping the water to fast thru the compressor to be able to extract the heat properly due to the water moving to fast.
In some cars if you take the thermostat altogether they will over heat just as if the thermostat was stuck since the water passes thru the block to fast to remove the heat properly and they overheat. Could do the same thing in the compressor. Might just be a faulty temp sensor. Hope you get it fixed.

I would definitely get a cheapie infrared thermometer and verify that the thermocouple is reading correct. I'm running "super coolant" in my 5 gallons of water (and have been from the start so I'm not sure if it helps at all) and mine takes quite awhile to get into the upper 30s*C. Check to make sure the fan on the motor is spinning as well. And check the flow valve on the water pump as well.
-
I thought about the infrared thermometer and I have one called a Thermohawk but it needs new batteries, the story of my life...lol
There is no air trapped as the water flows through fairly well but I just emptied the bucket and was checking the pump and I think it was turned down all the way as it seemed a little more water flowed when I turned it all the way to the other side. The ones I ordered are adjustable also and I plan to start with it at the lowest setting. But the difference did not look that great but it did work at emptying the bucket a little faster. I also bought a bigger container at wally on Friday. I think it was a 78 litre tub($12 and change) with locking lid that I am going to set up. Fill at least 1/2 way and put small holes for the tubes to go through in the lid, input at one end and output at the other end of tub. The larger size will allow me to put more ice or blue ice in the water as I have a couple of two liter bottles full of water I froze to use in it and prolly will make 2-3 more. I used to do that for the ice chest when going fishing.
Yeah I have an old 93 chevy with the 5.7 in it and I run it without a thermostat in it as it runs cooler without one for some reason but know what you are saying. Well I did run it until my wife broke it...lol
Thanks for the suggestions guys. I may have to find my thermohawk and try to put a charge on the batteries where it may work long enough to get a reading.
And I just checked my email and here is the reply that I got back. Quote:
"J**** S**: yes, i know that. we write a lower temperature for safe, and it is usually for winter. summer is can be 80C"
Well now, I guess they want me to cook with it also....lol As 80C is 176 degrees Fahrenheit. I will know more tomorrow if the new pump comes in as expected. The one tomorrow is 120V and the other one coming later is from china and is 240V so I can use the same outlet as pump.
Oh, and while it was running that hot I felt the water coming out of the pump and thought it should have been hot, but was barely warm. But if you touch the pump, you won't leave your finger on it at all. Both first and second stage are very hot to touch along with the metal tubing. It also made the metal paintball tank get warm from the air being hot. I don't know if that is normal or not.
It just don't make sense.

My compressor water is hot in the bucket. I just let it go. Tops off my 68 ci bottle just fine and tops off my airguns too. So far doing the job.

So, how many of you guys have topped off a SCUBA tank from 2000 to 3000 psi? I'm just curious if it's going to be worth it to try one of the less expensive/smaller compressors to top off my tank or if I should try to keep using the local fire department to fill the tank.

Or even 2700 to 3000 psi (a good afternoon is about 300 psi for me).

I did not think to take any pics of the liner with the guts in it. Its not very scientific other than the research on the best molecular sieve medium to use. When you get your filter it will have two paper filters that run the full length of the unthreaded portion of the tube. They have no liner included so that's where I decided on the thin vinyl type of cutting board. Just cut the vinyl the same length as the inside the body of the tube minus the threads. Then roll it up to form a tube and size it so when its rolled up the correct size to be a snug sliding fit and there is about 1 1/2 to 2 inches overlap on the liner. I rolled it up outside the tube to get close for the first cut and then installed the cut piece in the tube and mark each end where I wanted the final overlap to be. Cut and use the clear packing type of tape or similar tape to tape the outside of the liner in that size tube and tape the full outside length along the seam of the tube.
Then cut the paper filter that's included into 2 two inch lengths to pack at each end to hold the sieve medium. I placed one cut paper filter piece in one end of the vinyl tube till its flush with the end of liner. Stand the liner up vertical and slowly pour the medium in the liner until there is about 2 inches of the liner left unfilled. Then holding upright still tamp the end of the liner on the table with your hand around and even with the end liner so your hand cushions the hammer effect. You are trying to compress the medium so its packed tight as possible with out crushing or compressing the beads of the medium. When you are satisfied that you have it filled so you are happy with the height of the filter and medium in the liner. Screw both caps on and judge if its a snug fit. Then remove liner and one filter from one end and pour the beads out into a container to reinstall in a bit but leave the previously installed paper filter portion in place in the bottom of the liner. The idea is to make the stack of paper and medium in the liner so that with both caps screwed all the way on and tight is that the liner and mediums are held snuggly in the sieve tube.
Now with both caps off the sieve tube slide the liner into the sieves tube until the end with the paper still in it is even with the start of the threads in that end and screw that cap on tight . Then refill with sieve medium and tamp it down lightly. Then install the other paper filter in the end and screw the cap on tight and install fill fittings.

So, how many of you guys have topped off a SCUBA tank from 2000 to 3000 psi? I'm just curious if it's going to be worth it to try one of the less expensive/smaller compressors to top off my tank or if I should try to keep using the local fire department to fill the tank.
+1
Or even 2700 to 3000 psi (a good afternoon is about 300 psi for me).
Empty scuba tank took me over an hour with this compressor but I do not recommend it. Topping off a scuba tank took me from 4500 down to 4000 15 minutes to top off at 4500. 2000 to 3000 would not take a lot to top off. I just would not do a empty scuba tank from empty. Now it can be done as I demonstrated in my you tube video in steps. This compressor is not designed to fill an empty scuba tank. Topping off one I personally would do or small guppy tank or airgun itself👍🏾

Thanks guys.
This is one that I was looking at to consider. I just haven't read enough about the compressors in general to know what I might be getting myself into.

The compressor in your link looks a lot like the air Venturi blue one but in red😳 Hmmm
-
Nah, they don't do that kind of stuff over there.
Think that one should work for a tank top off ok?

Well you should go to TAG and read the review on the nimrodair compressor that guykuo posted. Just to know what you might get.

To help the cooling, this product may work great. I have been using it for years in my dirt bikes when I run just water in the radiators. It does drop the temps better than just plain water. It is also totally safe on metals.

Pretty much the same stuff I'm running in my bucket. I can't tell a difference but then again i never ran it without the stuff in the water. I figured it couldn't hurt anyways.

So the water wetter did not bring down the temperature in the bucket?

I don't know because I never ran just straight water. The stuff worked great in my car when I used it though! I haven't been able to shoot much due to wind and lack or squirrels but when I need to top off my guppy I'll post what max temp gets to.

As far as trying to keep the air as dry as possible, what do ya'll think about putting a desiccant filter on the input of the compressor? It's done on one brand of a hand pump. I have two of the Harbor Freight ones I bought some time back and am thinking about taking the little filter off they put on and putting the HB one on after the one that came on it. Just worried it might cause it to run harder trying to not so good air in.
And I also found a larger filter for the output side like was posted earlier here, more $$$ too, but is a little larger.

I am using the stock output air filter on the output side and on the same line using the diabolo air dryer system same as the one from AliExpress but red in color as double protection with no problems thus far
-
Just a side note on the water wetter, it should make the water in the bucket hotter because you are drawing more heat away from the cylinders. It reduces the surface tension of water so it can draw heat from metal better without boiling and creating steam pockets which do nothing to help cooling. I've noticed the effect when running it in my bikes, the coolant warms up faster but is more stable and never boils over

Mine is a diabolo air dry system minus the threaded holes on each end and red $179 not including shipping from an airgun store on the web😳😡. Now that's a good price on that filter. Could have bought 2 for the price I paid for one😡

Ken,
I think the Diablo has a desiccant inside where the Xin Yong Shi only has a large tampon. I put a vinyl liner in mine and added molecular sieve desiccant with 1" of the tampon on each end. That added another $22 to buy the desiccant. The thin vinyl liner keeps the desiccant from contacting the aluminum body.
-
The Diablo actually has molecular sieve beads inside of it. It's like a ceramic with holes that capture the moisture even in vapor form. Heating them in an oven will drive off the moisture and then they can be used again. There is some desiccant in there just for moisture indication though at the inlet side.

I received mine and stuck a length of 1" pvc in it packed with the descent and tampon pieces on the ends. The pvc helps reduce internal volume so it fills a little quicker.

How did you seal the pvc to the outer shell? So that the air doesnt go past your filtering media.

Actually going by the size or specs of it they are different. The one I posted is longer and larger diameter..
Yours says:10cm x 10cm x 400cm (3.94in x 3.94in x 157.48in) 1.8kg (3.97lb.)
And the one I posted shows: 15cm x 22cm x 12cm (5.91in x 8.66in x 4.72in) 3.0kg (6.61lb.)
That's why I posted it, as it seems like it is a larger one which may be better, but I could be wrong. But I don't know where they get that 157.48in from. It looks like a typo. This is copied from both pages.

Now you kind of lost me there? What are those dimmensions?
Filter they are not, for that is 50x350mm.

That is the shipping box dimensions... I don't see where they list filter size, but I'd think the extra couple pounds must be something.
-
I ordered the air filter from Ali Express its in the delivery phase now. In looking at the pictures for the filter that is 350mm long they show a pic. after filling so many tanks and it looks like there is a liner inside of canister alteady. Its made by Xin Yong Shi company and the product number is 83646475539127. Am i lookoing at this wrong ?
Pete
Ps went back and looked at pics I think its the oring on end of tube ;D
-
I measured mine and the tube, including the end caps, is 50mm diameter x 350mm long.
-

Marko
Compressed an o ring on each side when the caps get tightened down. Not sure how well it works but the air definitely smells cleaner on the outlet so its gotta be doing something. I need to find some better fitting seals though. Maybe just a rubber gasket would work better than o rings.
-
I got my compressor working again. If your's keeps tripping on overcurrent, try replacing the 2nd stage rings (you ought to get a set of 4 with your compressor). It isn't a tough job to do just be sure to put some of the same oil in the crankcase on the rings ( just a light smear... doesn't take much). If not you compressor may not spin at all on startup and continue to trip the overloads, ask me how I know. I let it run in for about 5 minutes to set in the new rings then put it under load. Hopefully this lasts for a little while and hopefully if anyone has issues with theirs they will know where to start.

On your diabolo air dry system , is the inside of tube coated so the desiccant packing does not touch tube ? I have a dryer coming from China ,should be here this Tuesday. I have been reading of vinyle and pvc liners used on the China dryer. Would like to know what it looks like inside the diabolo .
Thanks Pete

No liner just aluminum and desiccant

Thought I might have been missing something, not the sharpest tack in the box :P. Havent used my compressor much . The first time I just watched temp on motor and cylinder heads. The water did get warm ,took about 20 minutes to fill my air venturi tank(90 ci) from mt to 4500 psi. After filling Av tank looked at filter,that came with unit, it was dry but had a order to it, and the air from tank smelled the same. thats why i ordered the bigger filter . Going to cut the filters that comes with into 1 inch pieces. Put one in bottom fill with desiccant one on top and assemble. Also going to change the lubrication from hydraulic to the Chem Lub 751. Will let ya know how all turns out. If the rain would stop might get more shooting in.

You mention a funny odor, I too smell an odor when filling but I figured it is normal? Does not seem to affect the compressor. My compressor oil has a dark tint. I too ordered the chemlube 751 on fleabay.

Call it a lucky guess. I have removed the head already about about 5 0.35L tank fills to 300 bar just to check for dieseling and oil blowby. Yes I had plenty to clean out on that initial teardown. I guess I messed up the 2nd stage rings in that process. Anyways I checked the capacitor and it was within 5% tolerance of its rating (if memory serves it is a 120 micro farad), Checked the amperage with no load and under load and found when it got to about 3300psi the amps would go up and trip the overload. The only thing that I could figure was that high pressure air was getting into the low pressure cylinder by way of the rings and causing the overload. Guess I was right. She's running along well again after a replacement of the rings.
If you need any parts I have seen quite a bit from SBtech and LG on aliexpress. pistons, gaskets, cylinders, whole head assemblies, etc. Seems that even if this compressor dies it can be repaired.

Mine is single cylinder tuxing style. Large water cooled head. As for the links, not sure how to do that for the whole store. Look st the sbtech store and the LJ high pressure store on aliexpress. You can click on the compressor like you have and click on the seller, it should take you to there store. Hope this helps.
Also, yes. I have filled up to 300 bar on a 68 cu in bottle. Seems to work just as good as ever.

I just purchased 3 lots of 10each rubber compressor rings from sb tech https://m.aliexpress.com/s/item/32761293607.html?trace=wwwdetail2mobilesitedetail&productId=32761293607&productSubject=two-stage-piston-ring-for-compressor-piston-rings-10-piece-lot#autostay (https://m.aliexpress.com/s/item/32761293607.html?trace=wwwdetail2mobilesitedetail&productId=32761293607&productSubject=two-stage-piston-ring-for-compressor-piston-rings-10-piece-lot#autostay). I also spent about an hour and a half today messing with my compressor. I snapped off an unused mounting tab to make it easier to pull the cover off and I also cut another retaining ring grove into the motor shaft. I'll try and take pictures tomorrow. The retaining ring groove is critical for the safety and security of the compressor. Without it my fan walked into the motor frame and began to shred itself.

Its back together but doesn't take more than 5 minutes to open it back up. I have the tuxing. Any specific pictures your wanting? Yes those rings are for the second stage brass piston. They don't seem to last long or I'm opening mine up too often haha.

I am trying to visualize what you are talking about with the compressor. Short of me taking mine apart, there is only one piston right. Correct me if I am wrong, there is a top and bottom rings? If you have anymore problems, can you take some pics and post for all to see would be 👍🏾

I think a lot of the failures come from us taking the thing apart. I am not seeing people complaining about failures with the units unless the user has taken it apart.
There is only 1 piston but you have to think of it like 2. There is a brass piston that is mounted top center on the regular piston. The 2 sections of the single piston operate in 2 different stages. The main piston drives air into the second cylinder that is in the water cooled head. The main piston does have 3 rings and the brass piston has 4. The brass piston rings are not rubber. Below is a link to the piston should you ever need to buy one.

Thank you for the links on the rebuild for future references. As I look at my compressor, the finned cylinder is the first stage followed by the second stage the top portion with the water lines?
-
That is correct.

I think a lot of the failures come from us taking the thing apart. I am not seeing people complaining about failures with the units unless the user has taken it apart.
There is only 1 piston but you have to think of it like 2. There is a brass piston that is mounted top center on the regular piston. The 2 sections of the single piston operate in 2 different stages. The main piston drives air into the second cylinder that is in the water cooled head. The main piston does have 3 rings and the brass piston has 4. The brass piston rings are not rubber. Below is a link to the piston should you ever need to buy one.

Thanks Jeremy, I agree that mine taking apart has probably caused more wear than not but that's just my nature to pull things apart. At least I understand the inner workings now so that's a plus.
My piston only has 2 second stage rings. Do you know what material they are? I don't think they're rubber but maybe a type of plastic composite?
I've ordered all my parts from the sb store. Shipping is pretty quick and they're helpful.

1" schedule 40 pvc with ~ 2" sections of cotton filter sandwiching the dessicant. Orings on the ends to seal the pvc.

1" schedule 40 pvc with ~ 2" sections of cotton filter sandwiching the dessicant. Orings on the ends to seal the pvc.
How tight does the PVC pipe fit inside the aluminum cylinder, is it a snug fit or is it smaller OD than the ID of the aluminum. If its a good bit smaller so there is room for it to expand to the ID of the aluminum cylinder it could crack or break apart causing contamination of the air supply. That or the o rings will blow out first so the air bypasses the medium like intended.
Hopefully its a snug fit so it does not have room to expand or break apart from the HPA. The parts rated to the 4500 + psi is the aluminum cylinder and end caps so if the PVC can expand either it will or the o rings will blow either way rendering the filter useless on first fill.

Its not snug where it won't slide out but there is resistance to it. I think it's near a perfect fit.

Have you filled a tank or gun with it in the filter housing yet to know if it holds up and stays sealed with the o rings properly. Just curious if it works as intended since I may look at doing it that way as well since it will reduce fill times by decreasing the internal volume of the filter.

Yup, I took that picture after topping off my guppy to 4500. If you do do this, I suggest leaving the cotton plugs sticking out 1/16" to help hold the Orings centered.

That's a good idea with the paper filter plus it also keeps the sieve medium in place properly.
Mike
-
Hey I'm smarter than I look, what can I say.
-
That is a very good idea if its ok with you I am going to copy. Now did you do this just to cut dwn on the amount of desiccant used or to stop the desiccant from making contact with filter ?

Go ahead and copy it up. I bought a 5' length of tube just in case. I did have to make a second one because I cut the first too short.
I made it for both those purposes. Kinda makes a filter cartridge this way. Also to cut down on internal volume so it doesn't take as long to pressurize.

Killfire, I am thinking about taking apart my compressor topend off even though at this point, I have zero issues😳. Curiously kill the cat I hope not😳. I am trying to understand how this little compressor works. Just wondering if I take the topend off, can I put the cylinder head back on or will I need new parts? Just curious 😳 I know if it ain't broke why fix it😎

You can do it but if there's nothing wrong yet I wouldn't. I definitely understand the curiosity aspect haha. The only reason I suggest not doing it is because it's kinda difficult to get things mostly centered back up. The paper gaskets are pretty thin as well but you can buy some similar raw stock from the auto parts store and cut some new ones.

Don't do it, It's a trap. lol. But seriously, If you want to see into its guts watch this video. https://youtu.be/DUwtx-iPlDI (https://youtu.be/DUwtx-iPlDI) The inner workings are very simple and totally servicable or you can purchase a new head if for some reason you ever mess it up. I'll tell you from experience though. One of those inner cylinders, where the low pressure air goes into the high pressure area, is filled something to prevent particulates from ever getting to the second stage. That stuff will fall out if you aren't careful... you've been warned. That cylinder is linked into the low pressure bleed channel on the right.

When you say the motor, what do you mean?
-
The electric motor that drives the compressor.
-
If the motor goes and trips overloads often, it is likely one of 2 things. Either a degraded capcitor, or bearing failure. If anyone has a failure of their motor, I do that sort of thing for a living and can probably help.

From what I saw three cap should be easy to replace and at least the motor has ball bearings.

That's what I'm talking about, members on this site are willing to help out with info on where to get parts and some common knowledge on how what to do if and when the compressor needs parts. Team players👍🏾
The more I use this compressor the more I like it😎

Informative video on the tear down on the two stage but would have been better if he would have gone down to the one stage
-
Ken, if you've ever been inside any piston engine it's pretty but the exact same. Aluminum piston with rings and a connecting rod. The only difference is the brass piston on top of the aluminum.
https://m.aliexpress.com/s/item/32793617028.html?trace=wwwdetail2mobilesitedetail&productId=32793617028&productSubject=cylinder-piston-and-rocker-as-picture-1-set-lot&spm=2114.13010608.0.0.bmNhnN#autostay
That's the low pressure cylinder and piston.
Also I think someone mentioned adding a dessicant pack to the inlet. You can do it but it dramatically cuts down on the pump speed due to restriction on the intake. You also can't "boost" it by running pressure into the inlet either. The motor doesn't have enough power to compress already compressed air.

I haven't even looked at my bearings yet. Are they sealed bearings? If so that is awesome. No need to grease them.

Or does it? Challenge accepted.

Ken,
Correct me if I'm mistaken, but from previous posts I assumed that you have the Yong Heng compressor? It looks like a different configuration than the Tuxing. Is there a similar video out there geared towards rebuilding the Yong Heng? I am presently torn between the cheaper Yong Heng and the more expensive Carette. I think the Yong Heng would be great for topping off my PCP guns but if I decide to get a SCBA tank, the Carette might be a better choice. Decisions, decisions.
-
Jeremy, I want to say they are sealed but I'm not 100% sure. If you can figure out how to boost it let me know. All I did was buy some adapters to hook up my large air compressor to it. I think it ran at like 10 psi but not very well.

I personally regret buying the Tuxing compared this this model of Yong Heng. https://m.aliexpress.com/search.htm?keywords=4500psi+compressor#/ (https://m.aliexpress.com/search.htm?keywords=4500psi+compressor#/)
Many sellers call this the boutique model. The reason is the dual oil water separator/bleeders. If oil is coming from anywhere it is from stage 1. I think the young Heng of this configuration would do better at getting rid of oil from that second stage where it becomes crucial that no oil, even the proper iso vg 150 oil, gets there. Also the condensate has more area to pool up in those separators. Only downside I can see is that I bet that high pressure bleed screw gets hot, real hot. Otherwise the guts are the same, just different channels between stage 1 and 2, and 2 and tank/gun.
Mind you I don't have a Yong Heng so I am speculating on videos and available parts I have found. I may get one in the future and run 2 small compressors in tandem for faster fill times for medium sized tanks or just a back up.

Elguapo99 I do have the yong heng compressor. The tuxing compressor and the yong heng are different compressors but function the same. Figured if I have to repair mine, should be similar in disassembly. I haven't searched you tube on the disassembly of the yong heng yet. Hoping there is a video or I might have to do a you tube video on mine if mine conks out😳 As far as whether or not to get a yong heng or a small compressor, yes works great for topping off pcp guns and a filling small guppy tanks and topping off a scuba tank. The carette is also a good option. Better compressor will fill up scuba tanks and made in china😳 Ali has the carette. Ask your self, how often are you going to fill assuming from empty scuba tank? When I bought my omega, I bought a scuba tank. Fill an empty scuba tank and haven't filled that tank from empty since. Just top it off. What I'm saying I'm glad I do have a back up compressor the omega. Had the small compressor been available couple years ago, I would have bought the small compressor I have now which is now my go to compressor. Small easy to move around, cheaper, parts are available. If the unit burns up, it's not that expensive to replace imho

Jeremy, we bought the compressors that we bought. Hard to say if brand a or brand b is better or worst? I am glad that there is parts available for both. as more reasonable priced compressor are on the market now, it makes it affordable for us airgunners to enjoy the dark side of pcps. I do like this compressor in the link that you provided https://m.aliexpress.com/s/item/32747591930.html
Has the water tank on top. If I had to do over again I would buy this one or the yong heng

I have the newer model Tuxing 220v compressor using a Simran AC-5000 transformer to power it. So far it's working very well. It will fill an M10 from empty to 3000 PSI in just a couple of minutes and top it off after shooting in about a minute. I bought a 16" Husky locking plastic tool box from Home Depot for $7 and drilled holes just slightly smaller than the coolant line diameter just below the lid with a small notch in the lid for the pump power cord to pass through. Coolant hoses are passed through those drilled holes and I use automotive vacuum line squeeze clamps to seal the coolant lines to the compressor head and those clamps stay on the lines when not in use. 3M trim tape was used to attach the pump to the bottom of the box. The coolant hose was a pretty loose fit in the top of the pump so I wrapped scotch tape around the hose until it was a snug fit into the pump then used a little superglue to seal it. I have the return hose just an inch or so long into the box and fill with water just below that level so I can see that water is flowing with just a quick look. When finished I can just disconnect the lines and the pump power cord, latch the lid, and carry it without spilling water to empty it if desired.
Overall I'm very happy with this setup so far. Only time will tell how the compressor holds up but it is a relatively inexpensive way to fill PCP's.
-
Kurt,
Which Aliexpress store did you buy your Yong Heng from? I see several different stores selling the same compressor with different prices and a wide range of shipping times.
-
I ordered mine through Chon Electronic Technologies. They seemed to have a good price with the compressor and shipping. I have been happy about the way they have responded to my inquirers. They have responded to all my questions within 24 hours except for one, but that one was over a weekend. They answered that the following Monday. Someone by the name Joan Shi has been the person answering my question. I figured that they have been willing to answer all my questions over a couple week period was a good sign. The day I got the notice it shipped they sent me an email about what language I wanted the instruction manual to be in. I answered and in a few hours I had a reply with the instructions attached. I also had asked about a larger separator because I didn't see any listed on their site. They sent 2 pictures with 2 different larger ones. Said they could ship with the compressor to help save on shipping. I ordered the largest one. I will have to wait to see if it comes with the compressor.

The latest message I received said it's waiting to clear customs. How long does that normally take? I guess that's why it's been sitting in Memphis since Sunday.
-
It won't clear customs until all of the agents have topped off their guns and tanks with it.

With all my luck that would be a true statement. They will probably wait until it needs a rebuild and then send it to me. >:(

I'm very tempted to purchase one. EBay will protect you if it's &^^& or doesn't show up and if it happens to actually be decent you have a great deal there. That seller does have zero feedback though...

Right with the eBay protection now that is a good buy😳😎

Thanks Ken for the heads ups.
Well for 70 bucks I took the chance and ordered one in 110 volt so well see if its to good to be true. I noticed they only had 4 available with one sold and now two sold.
I figure even if its a return or blemished model for 70 bucks I can afford to rebuild it twice or more and still be way ahead. it should be the first week in june so will update when it arrives.

I guess I shouldn't have waited to talk to the bean counter on those. Got up this morning and they were gone.

When I ordered mine it showed 4 available with 1 sold so I bought the second of the 4 available. Mine is showing shipped as of now with a 10 to 25 day arrival or June 1st to 6th time frame. I have already had a message from the seller letting me know the status.
I have one concern though in that the add states " high pressure hand pump 31MPA 310Bar 4500 PSI for air rifle PCP airgun " so it kind of makes me think of a bicycle type "hand" pump but it shows very clearly in the pics it is a electrical operated compressor. I thought I put a message in the purchase to send a 110 volt model but there is no message in the PP transaction. I replied to there message about it but have not heard back yet.
Just hope its what's in the pictures not the description or it will get sent back for a refund since already have a hand pump.
I will keep up to date.

If it's not a compressor you should be covered under "significantly not as described" as the pictures and the description in the body of the listing is for a compressor. The only issue may be shipping back to China so that you can get your refund.
I don't know the details but there's a trade agreement with China where they can send stuff to U.S. for $1 but U.S. to China has not discount and may be very expensive.

I have been told just recently that ebay requires sellers to pay for return shipping. I have had 2 problems in the past couple of months that involve overseas purchases. The first was my drop down adapter I bought. Was told by seller that it could not come back due to customs would never allow it back into Indonesia. But seller offered 1/2 my money back. The problem was in the threads being wrong. All I had to do was find a machine shop to repair them. So I got $70 back and cost me $20 at the shop. So that was great.
The second is a scope I just bought a few weeks ago. Came in and could not get it to sight in. Tried to adjust and run out of turns....lol So I sent the seller a message and have had a big run around with them. It turns out though that it was the cheap pot metal mounts they sent was the biggest problem. I let them know that but they kept insisting I send them a video of the problem. I had already sent them a link to one I found on youtube that was the exact problem I had, but that was not good enough. So the ebay time went by on the case to where I could ask ebay to step in to help resolve the issue. After that, they replied back with 2 options and one was 1/2 my money back, which I am waiting on now and I can close the case. The other option was for me to find the cheapest shipping option for them and they send me the money to ship back and when they get it they would give a refund. Not likely as we have the ITAR rules/law that govern exports out of the U.S. And scopes fall under that, as are considered small arms items and are controlled so it would be most likely the scope would never get back to them. I only paid $55 for the scope and 1/2 back will be fine. It is 6-24X50 with side parallax adjustment. They are listed on ebay as a M4 SBEDAR scope and average price about $60-70. Just another knock off scope but is not bad for the price.
So if it turns out it is not the electric pump as described, Ebay will help you. So either the buyer has to pay for the shipping back or you may get to keep and get at least 1/2 your money back if decide to keep and not to try and ship because there is always a chance they will never receive it and may try not to refund. You then may end up waiting a long time to get all your money back, that is unless your credit card company can help.

I understand that if it is not as described I can get my money back since it clearly shows a electric compressor not a hand pump. If its not as described then I will request a refund and they can send a return label.
I had not heard about any deal for cheaper shipping for them but I don't doubt it exist knowing how things work in trade agreements.
Just need to wait and see when I hear more from the seller.
I have never had any issue that eBay did not resolve to my satisfaction in a dispute but truthfully only have had two in 11 years of being a member. I have not heard about the buyer having to pay postage for a item not as described so will find out if the need arises. If its a hands pump and I get half back I can easily recoup the 35 bucks I am out by selling the pump. I feel good that it is as pictured.
My only issue is when I left a massage in the PP transaction to send the 110 volt model it showed no message was in the PP transaction when I received the email confirmation from PP. So if its wired for 220 volts when it gets here I will need to get it rewired for 110 volts but that's no reason to return or refund my PP but rather just provide a pic or instruction to correct it to 110 volts.
Stay tuned.

If you are shipping via container ship, US to China is way cheaper than China to US. Otherwise return shipping is high because you are a low volume consumer. Trade agreements don't really factor into UPS or FedEx proces too much.
I hate to say it but for $70 and with that description I would be expecting a hand pump. Descriptions generally are more reliable than pictures. Good luck and see if you can message the seller. Better for everyone to find out before it ships.
If you do end up that situation I would love to take the l pump off your hands for $35 :)

Bountyhunter76 how is your compressor doing? Mine is still going strong with zero issues so far😳
Ken, that is yet to be decided. I got the new pump in with a higher flow rate and got it hooked up. Does have a little more flow and helped a little but not much. I bought a larger tub, 78 litre or rather a 20 gallon tub, filled to about 65% and I place 3 2-litre bottles full of water frozen in the tub to chill it down and it still runs hot. I had emailed Joan again and her response was it could run 80C in the summer and was ok to run that high. The instruction book says 70C and she said they say that for safety. It still is no problem to top off a tank but about the max run time is 3 minutes before I shut it down because it will be at 65C by then. I changed my oil for the first time a couple days ago and it was BLACK, or rather as close as you could tell. I had the ChemLube 751 in it and it turned black and my total run time is probably not over 15-20 minutes since I first turned it on. All the videos I have seen on the pump, they show it running for 30 minutes or longer. It probably did have oil residue left in that they had put in that I could not get out, but the change in color of the 751 was gradual. So as long as I am just topping off my guns it is fine as it only takes a minute to do it. If anything changes I will let everyone know on here. Maybe there is something wrong with mine that does not let the water flow through where it is suppose to. Guess I will learn more when it breaks down. But for now it is still pumping.
Oh, got my new filter in today. I ordered the $60 one and it got here sooner than expected. Heavy little bugger. I guess it already has a filter in it and came with a spare set. Anyone have the link for the correct spares to buy for it? I tried searching on there but was unsure about which ones it is.

Yea I thought the same thing after I paid for it and read the title closer so I did message the seller about it as well but have not heard back yet so hopefully they will respond with the info on if its a hand pump or compressor. For me its bad business to show a pic of the item in the ad as one thing when in fact it is something else. The eBay page does not ever show or allude to a hand pump other than the title so its a toss up as to which it is. But the fact that the seller has 0 feedback I would think selling a incorrect description of the item is not a good way to start off with eBay or the buying public. I know a satisfied customer tells a few people but a dissatisfied customer everyone they can so its best to not be vague in your descriptions and pics of what you are selling.
I will keep you in mind if it ends up being a hand pump.
So now we see another way our corrupt DC bends us over once again. If small business operated like our govt does we would have no place to buy anything locally since they would all close the doors in a very short time. So much for fair trade and commerce.

Just curious, for those that have bought one of the compressors, what was it labeled as on the paperwork that came with it? They had mine listed as computer batteries....lol

I went back and looked up the original listin. In the title it does say hand pump, but in the description it is all compressor. I don't think a hand pump will be 15 kg unless it belongs to Conan the Barbarian.
-
Yea I saw the weight in the shipping email as 15 KGs or roughly 33 pounds so good chances its a compressor versus hand pump.
My bets on compressor.

I have 3 hours on my compressor and my oil is black as well. I don't feel like it is hurting anything though. I may change it soon and see if it darkens again. Strange your pump is heating up so much. Which one do you have again?
https://m.aliexpress.com/s/item/32771088772.html#autostay
That's the gold filter replacement element I believe. I would look into building a dessicant pack like others are as well. You'll use less cotton per filter and I think the sieve dries better as well.

Thanks, I believe those are the ones. I have been thinking about changing to the desiccant beads since reading the posts about it. I will go back and read again to learn more on it.
If your oil is black also I would change it if it is your first oil you put in. That is your break-in oil as I call it. The second oil filling may last longer without turning black but who knows, it might turn quickly also. I just felt it needed it since this oil had the first running on it.
My pump is the Ace Eagle. I bought it after reading on the Talon forums where a member there had one he had been running and running without issue, so I thought I might as well try it. I guess it is sorta the luck of the draw like so many other things from over there. But it is still running and for just putting air back into my rifles, well, it serves it's purpose well and prevents me from having another heart attack working myself to death on that hand pump....lol
Oh, and I am not saying I had a heart attack while pumping, but have had two already and if were to keep using that hand pump it could bring one on. :(
Better to spend a few hundred than be out a lot more or dead. ;) And I don't like the idea of my other half having my air rifles, ya'll would probably end up with them... ::)

Here's what I did for the gold filter.
1" schedule 40 pvc with ~ 2" sections of cotton filter sandwiching the dessicant. Orings on the ends to seal the pvc.
So, what do you put on the output side when it isn't being used to prevent ambient air/moisture from getting inside? Just a foster plug?
-
I put a foster plug on the output side and I disconnect the input side and cover it with a vinyl cover that fits over the male foster fitting.

Mine has a foster on the inlet and a hose on the outlet. I put a brass plug in the outlet side of the hose that came with the compressor. The inlet stays connected to the compressor through another hose.

Its starting to look like fed ex has lost my compressor. I haven't heard back since I spoke to them last week so I called again today. Last tracking update they have is from the 10th in Memphis. They said they have opened a case and are investigating. Doesn't look good at the moment. Not happy about it but I guess have to wait at this point. I did send a message to the seller to let them know. Maybe I'll here from the seller tomorrow.

That really $uck$. I just ordered one today off of eBay and it looks like I'm going to go through the "address not recognized by the post office" run around thing. not worthy for getting stuff shipped here sometimes.
-
Well the tracking status has changed. It now shows, international shipment release-import, not sure what that means. Still doesn't show a delivery date.

The compressor delivered today. It was sitting on the front porch when I got home from work. Package arrived in good shape and they had the compressor packed well. It seems to work ok. I filled it with the chemlube and hooked the water up. I left it run a few minutes with the bleed screw open. I used it to fill my marauder twice. Took about 2.5 minutes to fill it from 1800 to 3000. The temp went from 27.5 to 55. Not sure how much of a difference it makes but I didn't notice until after the 2nd fill that I had the hoses reversed. I had the pump line hooked to the upper port. The instructions say it should be hooked to the bottom port. I have the pump sitting in a 15 quart container. Maybe I should pick up a larger one. So far so good.

The idea of the inlet for the water being on the lower port versus the upper one is it takes longer for the water to be pumped up around the cylinder allowing for it to pick up more heat out of the metal than it would if its allowed to flow freely from the top port out the bottom since the water would flow faster from top to bottom than it does from bottom to top. Also with the water coming in the bottom port it automatically forces any air out of the cylinder since the air would be pushed out from the water filling the cylinder and out the return line. If the water comes in the top it could create an air pocket in the cylinder leading to overheating issues that could occur erratically since it may not trap air every time used.
The temp going from 27.5 to 55 in two to three minutes seems like a faster increase in temp than it should for that short of a run time which could have been due to the water flowing the wrong direction and creating a air pocket. I would get at least a five gallon bucket for the water and freeze some milk jugs or soda bottles to place in the bucket to cool the water even more.
I have one on its way as well but not for sure if its the same as the others have bought here since it was one of the 4 compressor that were on eBay for 49 bucks with 20 bucks shipping. The eBay post showed a Hong Yeng compressor but will not know for sure till it gets here. I will update as I receive more tracking info or reply's to my messages. I am in limbo at this time with it not landing in the states as of yet.

Mike that is an amazing price for the compressor, I remember seeing that when it was first posted, will be interesting when you finally get it.
-
I have the hoses hooked up correctly now. I will report on the temp next time I do a fill.
-
What is the flow rate of these water coolers?
I ask because where water is very cheap if the flow rate is low enough once through could be an option. Especially if you have a use for slightly warmed clean water. I might make beer this weekend since I plan to fill the pool, which is a great way to reuse the water from the wort chiller.

Yea I could not believe that they had them listed at that price. When I saw the link in Kens post I checked it out and decided to take a chance on it and ordered the second of four available. The listing has the word "hand" in the description about it stating it is a Hand Pump but shows the compressor so not sure which it is yet. I emailed the seller about if they got my message that I wanted the 110 volt model but my PP transaction message showed no note left so not sure if it was included in the PP payment to them. I have not received any message back on my inquiry so will see what arrives.
If it is indeed a compressor that is for 220 volt its still well worth the sale piece and I can afford to have a 220 line run to the compressor in my garage. Got my fingers crossed that its a compressor and not a hand pump. Already have a hand pump so should be able to at least get my money back selling the hand pump.
I will keep informed of what arrives from the seller.
Again a big thanks to Ken for posting the link.

I hope it works out for you Mike... that would be the deal of the century.

Kurt, your not alone if you continue to have it heat up like that. Mine is doing the same thing and has been since I got it. Mine has the pump connected at the bottom as per the instructions and the instructions also say not to go above 70C, which is hot! The seller replied to my questioning this and said in summer could go to 80C and they put 70C as a safety precaution. I shut mine down when it gets to 65C as a precaution. I started with a 5 gallon bucket along with 2 blocks of blue ice out of the freezer and it still went up. I have since changed to a 20 gallon tub filled about 3/4 full. And I have bought a higher flow rate pump also that seemed to help a little. Mine came with a 160gph pump, and now have a 500gph. But really can't tell a lot of difference. I have 3 two litre coke bottles in the freezer along with the blue ice that I chill the water down with and start the pump with it showing about 19C and it still will hit 65C in about 3 minutes or maybe just under 4 minutes. It still works fine for topping off my rifles for which I bought it for. And when I bleed the pressure off at the end there is water and oil that blows out and the oil part started just in the last few running's. I have changed the little filters in the filter at the end of the hose that came with it since I checked them and were dirty with oil. If yours did not come with the filter at the end, you had better get one. I even bought the $60 one from Aliexpress that the others have bought to add to mine but have found I can barely use it as it takes more than half my run time to build up pressure in the filter due to its size. My compressor came from the Chon Electronic Company and the person that reply's to questions is named Joan.
Not trying to be negative on it but just a heads up of what I have done and tried to keep it cool. I do hope that getting your hoses connected right corrects your heating issue. It has already saved me a lot of stress from the worry of hand pumping. I shot quite a bit on Mothers day and could not have done so without this little compressor. It is really a life saver.

So I ran it again this afternoon with the hoses hooked up correctly. I don't have a tank so just using it to fill my marauder. It took about 2 and 1/2 minutes again to go from abut 1800 to 3000. This time it went to up to 50. I guess it helped a little having the hoses corrected. I'm only using about 3 gallons of water. I did pick up the large filter they had. Mine came with the small filter and I have that going into the large filter. I only used it 3 times so I haven't checked them yet.
-
Allan,
Do you think maybe you can install two shut off valves on either in of the drier so you can keep the pressure in there when you're done?
Are the pumps the aquarium ones that the flow is easily stopped with your finger? Would a more positive displacement style pump work better or will it pop the hoses off?
-
I checked the small filter. It only had a small black circle right where the air enters the filter. The rest of it was still clean. The small water pump that came with it says its rated for 400L/hour. I imagine if you could keep it pressurized it would fill in less time. The instructions say to bleed it off before shutting off the compressor though. I think I read somewhere they say to do this to blow out any moisture from the high pressure cylinder.
-
This is my setup.

How long did it take the vendor selling the gold filter housing to ship? How long to arrive? Mine has been awaiting shipping for 3 days. Molecular sieve from eBay arrived today.
-
I hope it works out for you Mike... that would be the deal of the century.
Bill
Yea it would indeed be a deal of the century if it is in fact a compressor. I have a lot of faith it will be since the shipping notice I got from the seller showed shipping weight of 15 KG or 33 pounds so it would be one super heavy duty hand pump at 33 pounds.
I have the same gold large filter hooked up to my Shoebox now and have a shut off valve on the outlet side to be able to close the valve to retain the pressure from my shoebox to the filter so once its pressurized the first time I can fill much faster. It takes about 20 minutes for the shoebox to bring the pressure up to 3000 psi in the filter so the valve really helps cut fill times down once its all up to pressure. I only leave it pressurized for the days filling so once I am done filling I bleed it all off till the next time.
I believe that the another reason they say to bleed off the pressure after every fill on the Chinese compressors is so it does not start with HPA already built up since that is hard on the motor to start up against the pressure being in the cylinders from the previous filling. I will know more when mined arrives and I get it all setup and running. hope mine does not heat up as fast as some here are doing. Its interesting to see that some get hot fast and other do not, makes me wonder if the cylinders are sealing correctly or if some have a issue with piston to cylinder fits or poor ring sealing.

I got mine in about two weeks and it showed awaiting shipping for a few days as well. Be patient as it will be worth the wait in keeping moisture out of your tanks and guns.

I placed the order for mine on the 5th of May, and it came in on the 12th of May. At least that is the day I got the email requesting me to verify that I got it. Email came late that night so I either got it that day or on the 11th. Either way it got here quicker than I expected. ;D

Taso, I most likely could if I had the proper fittings etc for the pressure and size. But I had rather have my pump running cooler like it should. After watching all the online videos of the pumps running and filling at least 500cc tanks without stopping and over heating I have been dismayed. Makes me wonder if the videos are not being edited to make it look like running all that time non stop. I know one video doing a demo of one that I think was posted on here was suspicious to me as while watching the video and the long fill time on the big tank I noticed when panning to the compressor and back that the temp had conflicting temps on it. I noticed the temp drop from in the high 30's down to low 20's while supposedly filling the big tank. Never known of that to happen.
The little pump that came with mine is rated at 600l/h which equates to 160 gph. And is 240V. The one I have connected now if 1900l/h or 500gph. And there is not a whole lot of difference. The water stream coming back out into the tub is not trying to blast the water as you may think. If the water line was level and the water came out straight from the hose it may have traveled 2 inches and then fell down. The new pump it may flow out 3 inches and then go down. The new pump is also 120V and a lot bigger in size. I have another I ordered that came from China and is a 240V I intend to hook up and it is 660gph if I remember right, and is variable also as is the one currently running.
As far as it goes, I can fill my guns and will keep doing that til it breaks and then will decide what I want to do next. ;)
One other thing, I actually would like to see this little pump with a lower rpm motor on it. Might take longer to fill but would take a lot of stress off of it.
-
I noticed on all the video's online of the compressor running they only show the small filter in use. I wonder if the larger filter has enough extra back pressure to cause the increase in operating temps? I will try a fill with just the small filter and see if it makes a difference.

It is possible for the big filter to restrict flow enough to cause the compressor to work harder and heat up faster. I know my big filter filled with sieve that's packed by tapping the filter body on a hard surface to compact it tightly together before assembly of the end cap. I could still blow through it with my mouth quite easy so the filter would have to be packed super tight to restrict flow enough IMO.
Let us know if removing it help or not.

-
Just a thought on the heat issue. The video's made in China that show low temps are running the motors using 50 HZ electricity so the motors are most likely running 20% slower than with the 60 HZ electricity used here in the USA. I would think that the higher speed may be generating more heat. Just a guess on my part.
-
I noticed another thing last night watching one of those videos. There is one of a guy filling a tank. I notice he has the water output line running into a drain in the floor. He doesn't show where the input line comes from. I would take it that he is using a constant supply of cooler fresher water to keep the temperature down on the compressor.
-
To be honest, I am using an tidey cat bucket filled half way, dropped in the pump and let the pump do it thing. When I first got the compressor, I used a reusable frozen ice pack that I added in the bucket thinking it would aid in the cooling of the compressor. It did not make a difference in the tempature so, I stop using it. I just use the water in the bucket (hot) and let my compressor run it course which so far is doing well. What I am saying, don't worry about the heat and let it run.
-
Thanks for the input and piece of mind KZ. Since I'm only using to fill my gun I don't think I have anything to worry about. I'm not hitting the max recommended temperature. Just surprised how fast it heats up. I did do a little experimenting tonight with the filters. I ran with just the small filter and then with just the large filter. Pressure fill was same as before 1800 to 3000. With just the small filter it only took a minute to fill my marauder. Temp went up to 40. With just the large filter it took 2 minutes to fill and temp went up to 50. Last time I filled using both filters it took almost 2-1/2 minutes for the fill and temp was at 50. I also opened both filters to check. Small filter still just had a small black spot at the entrance. It did feel damp. The large filter also had a small lighter dark spot at the entrance but felt dry. To be safe I'm going to continue to use both filters.

I use both inline except I use a diabolo air dry system which is the same as the gold filter but mine is red and cost three times more than the gold filter😳 My compressor so far keeps chugging along hot water and all
-
Another side note for what it's worth, I use this little compressor more often than my omega super charger and no I am not selling it. Just a backup or if I for some reason need to fill an empty scuba tank which is not that often. Compact lighter than my omega which is a plus when you want to move it around. This compressor works for my needs. Topping off my guppy tank or my scuba tank when I go to the range to shoot or plinking on my back deck or pole barn. I like this compressor for it's portability charging the airtube on my airguns is Super fast. Sure beats a hand pump😎. At the time I purchased the omega, there wasn't much to chose from. Heck now I could buy approximately 5 of these little compressors for the price of one omega compressor😳 My choice is for the little guy. If I had the choice when the omega compressor was purchased, it would be this compressor. No doubt about it. Cheap enough to buy if mine is beyond repair. Parts are cheap to rebuild repair this compressor which is a plus. I'm not a salesman trying to convince all or any of you, just telling showing you with my you tube video first one btw what I like about this little compressor is All. Hope this helps others made a decision whether or not to buy one. I would in a heartbeat but another if my little compressor dies on me😎
-
I bought the one I did to be able to fill my 45 minute SCBA and my 80 CF scuba tank faster so I don't have to watch the shoebox most of the day when filling those tanks. I just hope it does as good as the ones here show being able to fill tanks faster when topping off. If it does that then I will be happy and for what I paid I can rebuild it several times and still be dollars ahead of the game. Now just hope its actually a compressor when it gets here.

It will be the compressor. I see mine made it to Honolulu today. Now that it's in the states kinda, I feel a little better that I might actually get it.

Did you order your compressor from eBay for the 69 bucks shipped deal and if so when did you order it. I bet it is closer to you in Hawaii from China than to Alabama so may get to you sooner.
I have faith it will be a compressor as well.
Mike
-
I didn't get the deal you got. Mine was $325 shipped. Ordered it on the 15th and it shows expected delivery on the 22nd. Hopefully it'll be waiting for me when I get home on Tuesday. It's stuck in Oakland, California right now.

Not many worse places to get stuck than Oakland!
-
I guess for the price mine is on the slow boat from China since I ordered it about a little over a week ago and it shows in eBay to be delivered between the first and sixth of June. So for the price I will not gripe about it taking 3 plus weeks to get here.
Mike
-
Not for nothing but... I ordered a case for my cell phone from China for $3.69 and free shipping on the 5th of May. The delivery window was May 18 to June 14. The only tracking I got was when it was accepted and picked up from the shipper a day or 2 after I ordered it.. I figured it as a $3.69 lesson. On may 19th it showed up in my mailbox. I was pleasantly surprised.
-
I have found over the past 2-3 months that items bought through AliExpress come in pretty quick, like my compressor and the large filter. But items bought through Ebay has that old saying, "slow boat from china" all over it and should be added to the ad. So when I use the search feature to find what I am searching for I select U.S. only over on the left side to cut out all the slow boat items. I am presently waiting on another scope that I won the bid on and did not get a tracking number for, which is a first for me, as all my other items had tracking info.
-
I've bought several items off aliexpress and got them in less than a week, so I'm guessing these long wait items aren't actually in stock by the sellers. They probably collect money until they can buy a pallet of something then start shipping.
-
I think they already have some items warehoused in the US. Other stuff actually comes from China. I really don't think they have ships that can come from China fast enough to make a delivery to your door within a week of ordering it. And I kinda doubt anyone is getting free shipping on air freight.
-
Respectfully disagreed on the shipping times, they use airplanes too. Here was an order for a hand pump, I received it in 4 business days...faster than the FDpcp I ordered the same day. Fedex IE means it shipped from China. But since that costs money, they don't normally do this and it goes on the slow boat( I now see it was maybe a promotion). Yes I paid too much for the pump but this was a while ago. Product Details Price Per Unit Quantity Order Total Status

Mine shipped from China on May 6th and delivered on May 16th. It had sit at customs in Memphis from May 7th through the 15th. It shipped Fed ex air from China to Anchorage and from Anchorage to Memphis.
-
Mine from eBay only shows it has shipped but no tracking number given so just have to wait till I see it on my porch. The seller is also new to eBay and mine was there second sale so took a chance but for the deal I figured the risk was worth the gamble. Since its eBay I fell better that if it is not as described or does not show up I can start a dispute which generally go in favor of the buyer. Time will tell.

-
Well, I ordered the filtered and it shipped 5/19... Or so I thought. The tracking # was provided on 5/19. Item was delivered today to BOWIE, MD. I'm 880 miles SW of BOWIE, MD. :-X
I've sent a message to the seller since I can't open a dispute yet. I included a snapshot of the DHL tracking path and asked for the correct tracking # if the item shipped. Hope I either get it or my money back.
This is the 2nd thing I've ordered from AliExpress without success. At least I did get my money back on the 1st item.
-
I have ordered several items from Aliexpress with no issues at all with one being the big gold filter and all items were received with in two weeks of orders being placed.
Hope it works out for you with your filter.

Well, I got my compressor yesterday and finally got to get it set up today when I got home. Read the chenglish instructions and think I got the most of it right. One thing that was not in the little book was an operating temp. What is too hot for the little guy? Oh, this is the little blue Yong Heng one off of eBay.
I don't have any guns to top off yet and I need a double male connector to work on my tank. Kinda not worthy because I have to leave for work tomorrow and won't be home until Saturday.

I can send you the instruction info they sent me that has the temp info in it which she later told me it could go 10C higher in the summer...lol Anyway my instructions said max temp of 70C, which is pretty hot being 158 Fahrenheit. :o Good luck with it and enjoy.
-
Thanks, that would be great. My instructions were a whole 2 pages long and didn't really tell that much. For instance, the bag of o rings and seals is just that, nothing telling you what which one is for or where to put them. I guess if something goes bad on it I'll be able to track it down.
-
Mine came with a bunch of extra o rings also. It would be nice to know what they are for in case I ever need to use them. Hopefully I won't have to worry about for a long time.

Rich, I tried to use the email feature to the left but it won't let me put the file with it. I guess I would have to have a regular email address to send it. It's only 281kb so not very much to it. It's more or less just the specs and simple instructions but all english.

I have a few questions on these little compressors....
1.) Are they stand alone compressors or do you have to supply them with shop air?
2.) Has anyone tried to supply them with shop air if they are stand alone?
3.) What are we seeing as far as life expectancy out of these, I don't want to spend $400.00 on one and have to rebuild or replace it every couple of fills?

1) They are stand alone minus a cooling tank. No shop air required.
2) You can't "boost" it with shop air. The motor can't compress anything above ambient pressure.
3) Not sure. They will probably last longer if you don't open them up at all. Any issue I've run into has probably been my own doing.
-
Apparently they shipped a new filter the day of my inquiry regarding the item arriving in BOWIE, MD. That's when DHL sent me a tracking # showing the item had been prepared for shipment. I got the filter today.
Just had a few minutes to look at it. Looks good but HOW do you get it open? I can't budge either end by hand.

Got it apart this morning, made the pvc "canister", loaded it with molecular sieve and got it all together. Great little addition.
Thanks for the idea and parts list!!
-
Great. Let us know how long it takes to pressurize the system now.
-
Just a quick update, so far all is well with the compressor 😎
-
I have got to use mine only a few times so far. Just quick rifle fills. I haven't gotten the big filter yet, but check the little one after every fill and nothing yet.
-
I ordered one last Sunday and it was in my hands on Thursday via DHL. I was shocked when I found it at my backdoor that night. Just got the synthetic compressor oil (Dewalt D55001) so now I can fire it up. I also ordered a Digital 400 bar shutoff switch which is on the slow boat from China. I found that I am too light (160 pounds) to hand pump from 2500 to 3000 PSI so I purchased the eBay Chinese Compressor. Bob
-
Bob,
Where did you order the shutoff switch?
Also, From which Aliexpress store did you get the compressor and which compressor did you buy?
-
If I ever get around to purchasing one I believe I'll be going with he Yong Heng from the Chon store. Wow, after reading that it reminds me of "Sum Ting Wong,” “Wi Tu Lo,” “Ho Lee Fuk” and “Bang Ding Ow" from that supposed plane crash.
I had originally planned to go with the Tuxing but I'm seeing more AMERICAN reviews on the Yong Heng.
-
Ordered a YH compressor from the Miznell Store on Aliexpress and it arrived 6 days later. Works great topping off my 90ci tank. It's a great feeling to be able to shoot as much as I want without having to manually pump or drive 30 miles into town for a 3000psi refill of my tank.
-
Bob,

The shipper was super and answered my emails within hours.
Here is the link to the shutoff switch which I should receive in about two weeks:
http://www.ebay.com/itm/162213381097 (http://www.ebay.com/itm/162213381097)
I plan on using a small 24V PS and I will find a way to tie it in the high pressure output.
I did pick up an HP adaptor from McMasters which will convert the 1/2" G-thread to SAE. Bob

Bob, did you get 110 or 220? How do you determine when you order from fleabay? I have no qualms with going 220 volt in the us, but it would make it far less portable, should I ever decide to take to he road or go to a friend's house. I have no friends. At least not with airguns in my city.
I was thinking the YH from Ali in 220volt to get that auto shutoff. I was looking at the Tuxing with auto shutoff and auto bleed, but I believe the auto bleed off is at the end of the fill cycle and not at multiple times during filling like the Caratte. Of course these little compressors don't seem quite up to the task to run long enough to have multiple auto bleed offs. And due to that I'd rather just do the auto-shutoff and just bleed myself as I don't see myself doing the "set it and forget it" but rather I would babysit it as it goes so fast. Although I was looking at the cheapo Chinese carbon fiber 2L tanks to go with this and that would take like 20 mins to fill those from empty. Perhaps longer.

My first choice was 220V but the shipper claimed that I could get the 110V faster so that is what I got. This eBay supplier had the quickest response time and quoted the best shipping via DHL which was great and fast. It was at US Customs in two days.
-
I am still waiting for my super deal compressor to arrive and its shows between the 1st and 6th of June as a arrival date so should be here any day. I am not sure if it will be 220v or 110v so if its 110v I will be able to use it right away but if its 220v I will have to run 220v out to my garage since all I have in 220v is the clothes dryer and the plug is not accessible at all.
It is on a slow boat but for the price I am not complaining at all. Still have my shoebox for filling tanks and guns for now.

I have the Tuxing version of these small Chinese made compressors. I considered running a 220 line to my shop but decided to buy a step up transformer to power the compressor off household 110 to be able to use it in air conditioned space if desired (cooler and drier air). Today filled my SPA M10 from empty after some work on the transfer port. It fills that rifle from empty to 3000 in about 4 minutes and topping it off only takes a little over one minute. Fills a Mk. II pistol from empty in just over a minute and tops it off in less than a minute. Very handy and I'm happy with it so far. I probably wouldn't try to fill a large tank with it (as the Altaros seems to be able to do OK but apparently takes a long time) due to heat generated. Several people have mentioned successfully filling larger tanks with these compressors by doing so in multiple stages.

Beats hand pumping😳

Where did you get a step up transformer and is it just plug and play or does it require some rewiring. That would be the best way for me to go as well if the one I get is wired for 220v.
I misread the shipping estimate that eBay gives for my compressor and it shows from the 1st of June to the 6th of July not the 6th of June so it may still be a month before it shows up. I guess for 69 bucks I cannot gripe to much since I am saving 300 plus bucks on it and have a shoebox to get me by till it does get here.

I am pleased with my Yong Heng so far also. I am only using it to fill my marauder. It takes a little over 2 minutes to fill from 1800 to 3000 using the large filter. I noticed I'm going through more pellets now that I'm not hand pumping.
-
I ordered the transformer from Amazon. Several "sizes" are available but I spent more and got the largest voltage model I could find to try to provide as much current as possible. It is a "Simran AC-5000W Step Up & Down Transformer". Simply plug it into a 110 wall outlet, plug the compressor into a 220 outlet on the front of the unit, and flip a switch to power it up. I've been using it inside the house since it gets hot and humid in Arkansas in the summer and cool dry air probably helps the compressor. It is working fine so far.
-
Now that's got me thinking I may indeed want to go with 110volt. I had intentions of using it out in the garage to minimize household disturbance with the sound of the compressor. I wasn't too much worried about the hot air in the garage which can get up to 110 degrees, dry heat. But I had always planned to use indoor air conditioned air so as to keep it as dry as possible. The 220 volt is out in the garage.
Scratch that, I'd just whip up a plug adapter for single phase 220 using my dryer receptacle. I've made numerous pigtails and extension cords for my welder to go with the numerous configurations in 220 so I'd just do the same for the compressor and still use it indoors with only some nuisance to the remaining household members.

That was my initial intent and probably the best way to go if you have good access to your dryer 220 line. Mine would be very inconvenient to reach as there is no space to the sides of my washer/dryer and the 220 line is low behind it. I would have to move it every time I used the compressor. I might eventually run the 220 line higher on the wall if I have trouble with this transformer but it allows me to relatively easily move the whole setup from room to room or to the shop or offsite where there is no 220 available.

Does the supplied cord on the compressor fit one of the two style 220v outlets on the step up transformer or did you have to change the cord on the compressor.
Bizill
With the made up 220v extension you show require that you must unplug dryer from the wall to plug the extension into the wall outlet or is it a piggyback setup where both the dryer and compressor stay plugged in all the time. My dryer plug is not easily accessible so it would have to be a piggy back setup if that's is even possible. I am not real experienced with household electrical but was a master auto/diesel mechanic for 45 years.

The 220 receptacle on the front of the transformer is a universal type designed to accept most plug designs. The Tuxing compressor 220 plug (which is identical to our US 3 prong 110 grounded and apparently this is a common arrangement for chinese devices) plugs right in. No modifications needed, it was plug and play. The transformer could also be used to power other type 220 devices from 110 if that were needed for some reason. Supposedly the transformer will also work for 220 input voltage (selector switch on the back for 110 or 220 input voltage) to 110 output but the plug for the transformer is standard US 3 wire 110 type so an adapter would have to be made. Now that I think about it there was another part in the transformer box that I didn't pay much attention to once I verified that everything would plug in normally. It may have been an adapter for US 220 to the 3 wire plug but I don't know right now where I put that plug.

Now that's got me thinking I may indeed want to go with 110volt. I had intentions of using it out in the garage to minimize household disturbance with the sound of the compressor. I wasn't too much worried about the hot air in the garage which can get up to 110 degrees, dry heat. But I had always planned to use indoor air conditioned air so as to keep it as dry as possible. The 220 volt is out in the garage.

Any possibility that you might remove those cover plates to see exactly how you wired everything up. I'm not near savvy enough with electricity and want to make certain that I don't end of with two hot poles rather than a single, as I understand that I need single pole 220 for my tuxing that has been waiting patiently. It looks like really fine work and would be much less of a PITA than finding space in my box for another outlet. Thanks for posting!

I read another discussion about single vs double pole 220 wiring. The last thing I took away from it is that it shouldn't matter for function of these compressors. But if it is the case that you need "single pole 220" wiring, how would you know which of the 2 available "poles" of the receptacle to wire that current to. Another person who made such a 220 supply to 110 receptacle box function and is using it for another Tuxing told me to wire one pole of the 220 supply line to one pole of the 110 receptacle and the other pole of the 220 supply to the other pole of the 110 receptacle and to be sure to clearly label it as 220 since someone not familiar with the setup could burn out a 110 device plugged in there. I'm certainly not an electrician but can mechanically modify stuff adequately so any definitive advice would be appreciated in case I ever wire this directly at some location.

Hey bill
You and me both. I was getting all psyched up expecting it to be here by the 6th of June, went back and check the eBay page for the shipping estimate time frame and I misread it thinking it was the 1st to 6th of June but see it states the 1st of June to the 6th of July so burst my bubble for now. Kind of wish it was a narrower window of delivery time so I wont be checking the porch for the next month every hour or so. :o ??? :(
I am not good at waiting with anticipation of delivery. ;)

Let's all be very careful when we talk about 220 volt. We're talkin' Single Phase, Two poles. I won't show the inside of my adapters as they are for my welder to connect from the various 220 outlets and the pigtails convert it to use my 100' 8 gauge extension cord with a NEMA 6-50 plug on one end and receptacle on the other. The reason I posted the pics is because I'm proud of my pigtails. <--- insert joke here.
If I get the 220 Yong Heng I'd have to make a similar pigtail to use with their supplied cord. It's looking like I'd have to take their 110 volt usa plug and convert it to be used as 220 volt which is very dangerous because if anyone tries to mess with my compressor and sees the 110 plug, things won't be fun. I won't know for sure what needs to be done until I have the money to order one. But I've got a good idea what it will entail.
-
In the US to get single phase 240vac, you will have two hot legs of 120vac and no neutral leg, unless you have a special transformer that boosts the single leg up to 220vac, not common but it can be done. I think that is what someone else bought back up the thread further, it isn't required but it does make it simpler to do it that way.
I have bee an electrician for over 25 years, the stuff hurts don't play around with it if you don't know what you are doing....

I appreciate the warning and the concern. (110v makes you say ouch and 220v makes you a corpse) I bought the Tuxing and what I believe will work, and please correct me if I'm not on the right track, is as follows. I've cut the end of the Chinese cord off and installed a NEMA L6-20P locking plug to replace it using these connections... White/GrnStripe attached to the ground terminal; Brown to the X terminal; Blue to the Y terminal.
It is my understanding the I will need to run 12 ga. (at minimum) or 10 ga. wire from my new outlet (NEMA L6-20R) to the panel that will be about three feet away. Ground will of course go to the ground on the panel, and if I understand correctly, the black and white will go to the two poles on the breaker and then I'm set. (making certain to label both as hot)
Where I am not certain is the breaker I will need. Should it be a standard 2 pole 20 amp breaker that is rated for 220v and will take 2 slots in my panel? My thinking is that this should give me 110v off each to get the 220v in single phase that is required to run this little compressor and keep it from becoming a $400 experiment gone bad. I'm just being cautious since this is the first time I've run into this type of situation. Wish I'd have ordered the 110v at this point...

I have no clue if it has passed thru customs yet or not as I have no tracking number to see exactly where it is so I guess I need to email the seller to see if they can provide some info or tracking number.

I am well aware of the risks involved with AC current and voltage and I have no kids in my house so I will be the only one using the compressor and it will be plugged in at all times so no issue with someone plugging it in or any other device incorrectly. I imagine there are possibly some codes that cover wiring a 120v plug for 220v use so I understand the reluctance to provide the required direction to do so on your part.
Mike
-
This is all exactly why I chose to spend the money on the transformer. I was assuming that the people who engineered it would have it providing voltage correctly but assuming can be dangerous. The Chinese 3 prong plug carrying 220 supply into the compressor is not standard for US but apparently is standard for China and the 220 output receptacle on the transformer is designed to accept that plug along with other 220 shapes as well. I've noticed no amount of overheating in any of the plugs or cords (wall to transformer, transformer to compressor, or water pump connection) and the transformer itself stays cool and the compressor runs/functions normally.

Mine was shipped as a 110 volt model which already had the US plugs installed on the motor and the water pump. My preference was 220 volts because of better motor/wiring cooling (less current) but they had more 110 V models available at shipping time so that's what I got. My shop has 220 volt wiring throughout so that was not a problem. Bob

110v makes you say ouch and 220v makes you a corpse
This statement is so wrong....
120vac kills more people in this country than all other voltages combined, why because people think what you wrote here 'oh it is only 120 volts' The minimum voltage to deliver a lethal shock is 30 volts.
People I will say this again if you do not know what you are doing call an electrician, it is worth the extra $50.00....
-
Thanks OTC. Good advice. My thinking was better to run the compressor on 220 supplied by the transformer than 110 since the Chinese seemed to design it around 220-they did not even have any 110 models available when I ordered so the 220 was the choice. One nice thing about the Tuxing version is the water pump is powered from the unit itself and not from a separate outlet plug so it may be a little simpler to connect for power (no separate outlet needed). The transformer was a not inconsequential additional cost but hopefully will be worth it in the long run and it would have other possible uses if needed (still totaled roughly what an Altaros would have cost). Mine is chugging along happily with this setup. Good luck to all using these-hopefully they will last a long time. Thanks for all the useful information from posters on this site.

well , its actually the AMPERAGE that kills you if we are getting technical.. Or overall wattage.. My fly swatter is rated at 2600 volts, It barely kills a bee because the amperage is about .0005 ma .. Ive seen guys build electric scooters on the other hand and think nothing of connecting 48v 40ah batteries to the controller unit.
-
If we want to really get down to the nitty gritty of what it takes to electrocute you it is in fact the amperage that is the most important value. In my specialized electronics class back when I was coming up as a auto/diesel mechanic the instructor made a comment about a former student that ignored his statement that it is possible for you to be electrocuted by a flashlight battery if you bypassed the skin as our insulator like the covering on any wires.
He stated if you take a Metal thumb tacks and puncture the skin of your fingers so its in contact with your bodies fluids ( the body is 80% water ) then touch the terminals of the battery there is enough voltage and amperage stored in the battery to electrocute a person. Of course he stated very greatly to not try this but take his word for it since one of his students did not believe him and tried it and is no longer with us due to him being electrocuted.
The new Hybrid cars ( Nissan Leaf as an example ) are now an even greater risk for technicians since they have banks of batteries that are wired in series with a rated voltage of 480 volts with the capability of discharging in excess of 3000 amps at one time. The techs that are certified to work on the leaf go to several weeks of schooling and the dealer is supplied with a dedicated tool set that has every tool required to work on the car with insulation covering the entire tool except the very tip of the tools that actually contact the part. There is also a rope partition placed entirely around the car with the car being parked on a rubber mat that is four feet larger than the cars footprint in all directions. There is another tech that is standing by as a safety measure at all times the car is being worked on because with the 480 volt/3000 amps capability you don't get a second chance to make a mistake. You would be toast in a few milliseconds.

You are correct about the amperage being the killer. There's just a great deal more exposure to the public in general to 110v in the US and once you open up your panel there's plenty of amperage there to light you up. Most folks in most situations dealing with 220v or 480v systems on a regular basis are professionals and hopefully more cognizant of the dangers and have better safety protocols. Thus, it is plausible that there are many more 110v fatalities in the US.

Still waiting for my compressor to arrive here and the days are getting closer to the July 6th deadline for it to arrive. I have messaged them twice with no responses so not sure if they can read English and reply in English or are just ignoring me. Since I have had no response from them if it is not a compressor when whatever it is arrives it just tilts the table in my favor for filing a dispute with eBay.
I learned many years ago that the squeaky wheel gets the grease so I can squeak right up the chain of command at eBay if necessary to have it resolved in my favor. Mind you its not the outcome or way I prefer to handle it but if I cannot get them to respond to my inquiries then they leave me no other choice. Plus the fact that they are a brand new seller with only 4 sales does not go in their favor either so as the saying goes " time will tell "

Mike is the Ebay claim submittal window up at 60 days after purchase?
Thanks,

Its been so long since I filed a dispute that I am not sure of the time frame but I would think that the window does not start until I receive the item or the estimated delivery date has expired. I can assure you I will not be waiting even 30 days after the 6th of July and if it has not arrived by the 6th the dispute will be opened that day.
It was ordered and paid for on the 11th of may so the 6th will be inside the 60 days but just to be sure I am going to call tomorrow to find out the details in where I stand with a dispute. I will update after the call.

This weekend I gave the compressor a good workout in setting up two PP700 MKII's. The compressor ran flawlessly and the only problem was keeping it cool as it was 90 deg F outside and I had to use freezer packs in the water tank to keeping the head temperature below 60 deg C.(140 deg F). Originally I was filling a 90 cu in tank and than topping off the pistols but I found it easier to fill the pistols direct as it took less than a minute to fill them from 1500 to 3000 PSI. I probably have a total run time of about 3 hours on the compressor and the oil still looks clean. Bob

Eric, tell us a little about your h2o filter I see there.

Well still waiting on the cheap eBay compressor that I bought back on the 11th of May. I have messaged the seller three times with no response and now today on eBay it shows the seller is no longer a member of eBay. I tried to open a dispute but it has me sending another message to the seller. I guess it has to be after the estimated delivery end date of July 6th before they will open a case on it.
The eBay page I went to says I have 30 days after the end delivery date to open a case on the item. So if nothing shows up by the 6th of July I will be opening a case and requesting my money back. Or if a hand pump shows up it will be the same scenario since the item will not be as described also.
I was so hoping it was not a fluke but it is looking less and less promising every day that goes by. If I get the 69 bucks back it will be ok but was really wanting the compressor. Just have to cough up the cash for one at the regular price.

Ordered one of the Yong Heng's off ebay. It's in LA so it should be delivered here in Vegas by the end of next week.
Also ordered DeWalt D55001 oil for it. I'll get the first fill and maybe 2 changes out of the quart. assuming the compressor outlasts the oil I'll buy more...
Still need to order the HP filter from Aliexpress. Speaking of, has anyone found Yong Heng rebuild kits and burst disc's on Aliexpress?
-
I've bought rebuilds for the tuxing. I presume they are the same but you would have to double check against yours. Personally, knowing what I know now, if yours works as it should out of the box, chuck it up to PFM and don't mess with it. I've caused myself a lot of headaches opening it up to see how it works.

Ha! Yeah, normally I tear stuff apart just because I can...this time, I'm NOT. I'll fix it when it breaks, not fix it till it breaks ;)
I found parts for the tuxing on aliexpress, found a few yong heng parts but not rebuild kits. not sure what crosses over between the two as the heads look completely different...
Still trying to figure out the best way to search on aliexpress...I get more hits for what I'm NOT looking for...
For the burst discs, anyone make their own? Hopefully, I don't blow any, still I'd like to get or make a bag full just in case.

Yup that's PFM. I ended up doubling my burst disks cause they kept blowing below 4500. I have some extras still I think. If you need them I could mail them to you. Otherwise they are ~1/4" diameter and I think .013" thick copper.

Copper? Huh, they look brass in the pictures I've seen. Thanks for the offer but I don't even have my compressor yet...I'd just like to get spares at some point.
Anyone know the burst spec? 5500 psi maybe? I wouldn't feel comfy doubling them up...unless, I had a good quality, calibrated gauge. Even then, I'd worry about the gauge failing and launching the head rather than blowing the disc.
I did find this video, in Chinese of course...looks like it blew at 5500-5700 psi, if you trust the gauge.....

I don't run it unattended and I trust the gauge on my air tank. Although I did just install a new gauge on the compressor. I haven't checked it for accuracy yet though. I'll do it when I get home in a bit.

Yeah, I'd trust an SCBA or the like gauge on a good tank. Sadly, all my tanks have the smaller, paintball gauges or none at all(SCUBA). So, I need to get a GOOD, quality gauge in line and/or replace the one on the compressor itself for piece of mind and safety...
So far, all I'm finding in 2" 1/8" NPT is "origin of china" gauges. I'll keep looking or see If I can get a high pressure, 1/4">1/8" NPT adapter.

Go to McMaster Carr and search for their precision gauges, cost should be about $25-$30 for the one you are looking for.

Ordered my 110V Yong Heng from Ebay on 6/23 and it is scheduled for delivery via UPS on 6/29 from California. Some of the Ebay sellers are now stocking them in the U.S. I was able to get it for $308 shipped with the Ebay $15 promotion last weekend. I'm anxiously waiting its arrival.
-
I've noticed some on Ebay now from Hong Kong that are accepting best offers, and are under $300 with shipping. I think the market is getting flooded, gonna hold out a bit more and see what comes along. I really wish I didn't live 45 minutes from a fill station and need one of these.

Well I finally got tired of waiting for my super sale compressor to show up. EBay still shows it scheduled for delivery between June 1st and July 6th with no tracking info at all. I have messaged the seller 5 times with no response and the listing has showed the seller is no longer a registered user for two weeks now.
So I finally got fed up and started a dispute with eBay so if by the 29th I have not had any response from the seller eBay will get involved and likely refund my 69 bucks. When I spoke with an eBay representative on Monday they said the seller is still a member but has to get some things took care of before they will be reinstated, whatever that means.
I still want the compressor but have just lost faith that it will ever get here. So if I get the money refunded and it shows up as a compressor I will contact eBay to repay the 69 bucks that it was in the listing.

Yong heng Compressor delivered today!
So far, PFM ;)
Have about 90min of trouble free run time. filled two 48ci 3k bottles and my 90ci 4500. Took about 5min for the 48's and little over 10min for the 90. Each was about half full to start.
Worked on a 80cu scuba tank... 20min run then cool and change water. Did this 3 times, still need another run or two for 3000psi. Tank was at 1700psi to start. I'll be doing my normal top offs at around 2500psi so it won't take as long...
The dewalt synthetic oil still looks new, no darkening at all yet. No air leaks so far.
The filter is not up to the task, already knew this. I did Lots of drains during my fills, every min or two. I'll be ordering a high side filter and sieve tonight. Even though I don't think I put much, if any water into my tanks, I won't be filling any more until the high side filter delivers. Just wanted to get some running time before I spent another $100...
So far, for $324 delivered in two days....I'm ;D
Edit:
High side filter and sieve on order! Not sure how long it will take to get here, won't be using the compressor until it does...
-
Dang, man, I just got my 110volt from Aliexpress for $377 shipped, and I thought that was a good price. I wasn't diggin' any of the ebay listings but it seems some are legit.
I'm waiting on my fill whips to arrive and I can't use my Acecare scba until they arrive. Got the Yong Heng in quick order as well as the bottle and valve but all useless without DIN items.
-
My compressor is still holding up. Only problem I am having is the gauge not returning back to zero. Will have to get a new one.
-
Hey guys been following this thread from the start and recently got my yong heng 110v compressor took 6 days to arrive at my house....i have been using for the last few days and it works great except i have been noticing it heats up fast within 2-3mins of running it gets to 50.5c from a start of 23-25c pumps fine gauge just seems to read hot but everything is barely warm to the touch...i am gonna get a infared thermometer but just wanted to know if anyone else has one running hot or even what the average temp of yours
Thanks
-
Thats about where mine runs. Takes a about 2 minutes to fill my marauder. Temp climbs to about 45C in that time frame. The other day just for kicks I filled the rifle with just the small separator that came with it. Took less than a minute to fill and it only went a little over 30C.
-
Ok makes me feel a little better although i havent gotten my bigger separator in yet so this is with the small one that came with it... Filling the hatsan it gets to about 40 when its all done....its when i fill my tank from 1800-3600psi it goes to high 40s or low 50s but its still only a couple mins run time....i havent tried running any ice or additives in the water yet.... And oil is fresh....i just found it weird that everything is really not hot to the touch afterwards makes me wonder of gauge is wrong....which i will confirm after today with infrared....i appreciate the feedback and will see what happens

An idea just rattled through my head (with the other 2 BB's in there) as I sit and look at the Tuxing compressor and I recalled someone else posting about getting a higher volume pump for their system. I know that I've always heard that taking the thermostat out of a car can cause it to overheat due to the water moving through the system too fast and not having enough time to pick up heat from the engine and then shed heat in the radiator. I've never really bought that idea myself but then again I've never really tested it exhaustively either. But on these compressors the water definitely circulates across the head very rapidly. I have my water return line mounted just above the water level in the reservoir so that I can see the flow at all times and it is a fast moving stream. I wonder if the water is actually having enough time to "pick up heat" from the head? I wonder if slowing the flow down might allow more heat to be removed? Just wondering. I haven't used mine longer than about 3 minutes (to fill a fully empty M10) and usually more like 1 to 1.5 to top off a reservoir). I've noticed that although the head does get hot the hottest spot is the SS line connecting the upper and lower head sections.
-
When I first tested mine it was 90 deg F inside my garage and after two minutes of running, in filling a 90 CI tank, the head temperature went up to 60 deg C so I added two large blue freezer packs to the 5 gallon cooling tank which brought the head temperature down to 45 deg C. Right now I automatically add the freezer packs to the tank when using the compressor.
Other than the noise, I'm extremely happy with the Yong Heng compressor. Bob

The heat transfer formula is Q=MC*(T1-T2). Q is the total hear transfer, M is the mass flow rate of the coolant C is the heat transfer coefficient of the medium (1 for pure water), (T1-T2) is the differential temperature across the heat exchanger.
So the object of this is that if you increase the flow the DT(Delta temp) will change for the same heat exchanger. It is very hard to get more cooling out if the heat exchanger by just changing flow, best way is to make the inlet water colder....

Thanks for that Al but I think it misses my point. It's not so much the heat exchanger (the "radiator" in this case being whatever water reservoir we are each using") that I am wondering about since we obviously can ice that and get it cold. It is the amount of time that the water actually stays in contact with the head itself to allow heat to transfer into the water. I'm really wondering how much heat the water is carrying away from the head since the head is physically small (relatively little contact area with the water) and the water is flowing through it very fast. I have an infrared thermometer in the shop somewhere but I don't know if it will register water temperature from the surface to allow checking for any temperature rise in the water itself. My use of this compressor is short enough that it is not a major issue for me. For those needing longer run times it may be something to consider but other than slowing water flow I don't know how else one could change it.
I think I would try to find a high flow computer cooling fan to mount behind the head of the compressor to further aid cooling if it ever needs to run longer for my use.
I do recall a post noting that an owner of one of these small compressors had contacted the seller with concerns possible overheating and the information I recall being quoted from the seller was that 60C was not a problem. Certainly seems like cooler would always be better but maybe the concern threshold is pretty high. Maybe.

Do you know the flow rate?
Water in my area is very cheap, running it down the drain assuming it was only a couple hundred gallons would be fine where I live. I just want to make sure that the flow rate is low enough before I do that.
-
I haven't tried to measure flow rate-I have the stock pump that came with the Tuxing compressor and as noted my use times are short so heat has not been a major concern for me. I would suggest trying something like Water Wetter and recirculating the cooling water to maintain that chemical-it is supposedly designed to increase heat transfer from metal into water. When the pump is running there is a very brisk return flow into the reservoir and I believe it may simply be too fast to allow heat to transfer from compressor head to water. I may be totally wrong on the mechanism here so try your own research. The next time I fill anything with the compressor I am going to stick my finger into the return flow and see if it is "hot" in relation to the reservoir water (using a thermometer would certainly be most accurate for this). If it isn't noticeably higher in temperature than the reservoir water then it could not be removing any heat. I may try to restrict water flow to see if more heat could be removed but I suppose this could damage the pump long term. I still suspect that an external fan blowing directly on the head may be the most effective way to keep temperatures as low as possible on these small compressors but I could be totally wrong.
-
The heat exchanger i was referring to is the head of the compressor, not the water tank, the heat transfer rate of it is fixed by it's size and composition, pushing the water through the head faster or slower isn't going to change the overall amount of heat removed, there are two things that help.
1.) Colder injection water, this will draw more heat from the head since colder water in makes for a larger DT between the water and the head, there is a point where this gets dangerous when you get it to cold and you run the risk of embrittlement, I don't think this is much of a concern since the water would probably freeze before that.
2.) Improve the heat transfer coefficient of your coolant, I think you suggested it above.

-
I believe that for any given temperature in the reservoir there should be an ideal flow rate for coolant to maximize heat removal from the head. Think of the water flowing but VERY slowly. Would the water not heat up rapidly and therefore allow the head temperature to increase? The opposite condition would be the coolant flowing very fast and having insufficient time for heat to flow from head to water again allowing the head temperature to increase. I can't see the heat transfer being instantaneous-it takes time.
-
You could get an inline pond pump flow valve, splice it in and see if the compressor temps drop. Easy to play with the flow rate then.

I believe it was me that suggested the flow rate could be possibly to fast to transfer the heat to the coolant properly in theses compressors. I am basing that off my 45 years experience as a master certified auto technician. In my experience with cars that use a bypass coolant system that is incorporated into the thermostat housing itself where the thermostat serves two purposes removing the thermostat completely will cause the car to run hot and eventually overheat. The cause is that when the engine is cold the thermostat is closed so the bypass allows for coolant to flow within the engine block itself to prevent hot spots until the thermoset open and blocks the coolant flow inside the block only and allows the coolant in the radiator to enter the engine to maintain the proper temp. By removing the thermostat completely the coolant will not be forced out thru the radiator but rather still just circulate in the block only thereby slowly getting hotter and hotter till it overheats. So in this type system you would only remove the center of the thermoset by cutting the two raised arches that hold the top of the moveable part of the thermostat so it creates a restriction to the flow and causes the coolant to have to flow thru the radiator as well.
In a system that has a separate bypass system it is not an issue since the thermostat only controls the flow thru the radiator itself and not the engine block. In this type system the entire thermostat can be removed without any issues of overheating. Either way it is a definite that the coolant in an engine has to be constantly circulating in the block in order to prevent hot spots and the subsequent damage that would occur if it was stagnant until the thermostat opened.
With that being said I agree that the best way to determine if the coolant used in these compressors is flowing to fast is to monitor the coolants output temp with a thermometer in the output flow as well as the resevior to see if there is in fact a significant difference in the temp of the reservoir coolant and the output temp. That will provide a good estimate of how much neat is being removed from the compressors cylinder as the coolant flows thru the system. That would allow you to have a basis for adding a restriction in the output flow and to monitor it to adjust it for the optimal heat transfer versus flow rate.
If/when I get my compressor that is what I will be doing to provide the optimum heat transfer rate thereby keeping the compressor as cool as possible at all times. If using an infrared thermometer to read heat of objects be aware that any shiny surface is not going to provide as accurate of a reading as a matte finish will due to the reflective nature of shiny surfaces. It's best to focus on a dull dark surface as compared to a bright shiny surface. I don't believe it will be able to read the temp of the actual coolant since it does not reflect the same as a solid object but have never tried either so could be wrong on that account.

I don't have a lot of run time on my compressor so take this for what its worth...
My compressor was hitting close to 60c at the end of 20'ish minutes of run. I was using ice cold water at start up and changed it before I made another run.
I think the water is moving to FAST thru the head to get really good heat transfer. Some transfer is taking place, the water is warmer at the discharge than intake even after 20 minutes of run. Still, this tell me maybe more heat can be absorbed during that 20 minutes by reducing flow.
The included pump is pushing about 105GPH. I'm going to try an 80 GPH and see if I get better cooling. The pump is only $8, no biggie if it don't work better...
When I ran my compressor, I had a small, box fan blowing front to back. I'm sure this helped. However, next run, I'm using a fan I forgot I had. This fan is 120mm square and nearly 2" thick!, 120vac. It sounds like a freaking JET engine! boy does it move some air, I'd say 250-300 CFM, maybe more. it was used for cooling large enclosures filled with electronics. This fan will concentrate a blast of air directly across the cooling fin part of the head and push it all the way thru the motor housing.
I plan to try the fan first, then the pump. Then both. this should tell me which combo makes the bigger difference. Sadly, none of this will happen until I get my high side filter....
-
I can assure you. Decreasing flow rate will NOT keep your compressor cooler. Oldtomcat has it on the money. Colder intake water will make colder head temperatures. Flow rate wont mean much of anything on these compressors.
-
Jeremy, I don't know with absolute certainty which of us is right but I am smart enough to know that I can be wrong and would hope you are as well. If not, so be it and you can assure away but I don't do absolutes well when they are simply someones opinion. The very simple bottom line seems to be that heat does not move from the head to the water by magic-it is a physical flow and certainly would require time and the time rate would seem to relate to coolant flow velocity. If you disagree, feel free to do some experiments to define the issue.
-
When I first got my compressor I to was concerned about the head temperature. I added ice packs to the water and it did not make a difference. The conclusion I came to Is the high temperature is normal to run it the way it is. And so I did. No problem so far😎
-

You may very well be right. Still, for $8 it's worth a shot. No down side from trying unless your careless and let the compressor get to hot...I'm not that guy ;)
-
I remember reading a post from a purchaser of one of these small compressors (may have been Tuxing but I don't recall) who contacted the seller about concerns over high temps and was told that 60C was not a problem for the compressor. For what it's worth. I've seen 54C to 55C indicated after a 3 minute fill with spit on the SS line sizzling. I will definitely be adding a cooling fan for my peace of mind. Hope everyone's compressors work well.
-
Ken,
It's probably in this thread somewhere... anyway, what the max temp you've seen and how long did the compressor run to hit it?
My compressor temp gauge hit 60c when I stopped it for a cool down after 20'ish minutes of run. Not sure how much hotter it would have got OR if it would have stabilized at 60c for a time. The water supply was still cool, but, I didn't take a temp reading. The water coming out was very warm, but, not hot IMHO, again no temp reading. The finned portion of the head hit 65c according to my IR temp gun. The case was like 37c.
Maybe it will run just fine with these temps, I just didn't get a warm fuzzy feeling in regards to longevity running this hot.... I'd rather do several,shorter runs than let it run for to long at what I feel are high temps.
Trouble is, I don't really know WHAT is too hot! I've read you should stop at 60c and change the water, another post was 70c during summer months...
-
I don't think slowing the flow rate will help any. Think of a car running at idle and then think what happens when the engine revs higher. The flow rate increases if the water pump is driven proportionately to engine rpm. Usually you don't see them trying to slow the flow.
I think we're all overthinking this. Just add ice. Period.
-
Overthinking it? Isn't that half the fun. I'll still disagree with you just for kicks and I can give you a specific example. I drive a large International chassis RV type unit a couple of times a week. As temperature goes up you hear the fan clutch kick in and temperature drops. You aren't revving the engine to increase water flow but moving more air to cool the water in the radiator. The automotive accessory drive system is designed to move adequate water at idle for cooling but air is another matter. You're comparing apples to oranges. But I'll also agree with you, add some ice and fill your tank or gun and go shoot. If it quits working I'm sure we will try something else.

Run time approximately 20 minutes topping off a cf 88 cf tank temps 64 to 67 c running the pump in a bucket of water. Filling my guns anywhere from high 40s to mid 50s. I accepted the fact that the compressor must be designed to run hot each to there own.
-
Come to think about it, I have a two stage5 hp compressor twin 60 gallon tanks in my pole barn that get hot if I use a da sander while doing auto body repair and that compressor is not water cooled and has a finned cylinder heads with no overheating problems so maybe this applies to these little compressors?
-
Shultz. I hope it didn't seem as if I am trying to get into a I'm right your wrong ruler match. That is not my intent at all. The way this cooling system is basically is a volume of water must be able to absorb the total heat losses of the compressor. The heat the water rejects to the atmosphere is negligible. I am not sure what water source you are using but I do well with a 5 gallon bucket full of water from an outdoor spigot. It keeps my unit mostly below 40C. Granted I have to change the water at 15 minutes if I run that long.
I also don't want to seem like what I am saying is opinion. It's physics. I work in the pharma industry with a focus in automation. Heat exchangers are not uncommon to me, in several various forms. I hope to be a help as that is all I was trying to do.
-
Everyone here has good points on how is the best way to remove heat from the head of theses compressors so don't think anyone is right or wrong specifically. The only true way to know is to experiment with different setup and flow rate and watch the results. I was hoping to be able to do them myself soon but just found out that the compressor I bought for the super price of 69 bucks shipped will not likely ever show up and I received my refund from eBay for that compressor. Bummer.
In regards to a car engine and said cooling system working at idle versus at speed down the road with higher revs from the engine. That's why there is a thermostat in the engine to control the flow rate at which the coolant can flow thru the engine. Yes with higher revs the water pump spins faster which tries to speed up the flow but the block, water pump passages and thermostat all restrict that flow so that it can only move so fast regardless of how fast the engine is turning. That's is exactly why a engine without any thermostat at all is slow to warm up and will likely eventually run to hot if not overheat because the coolant is moving to fast thru the engine and radiator to shed the little bit of heat it picked up out of the engine. There has to be a balance between flow volume and speed in order for the system or any system to work at peak efficiency. This is why some vehicles have a larger radiator than others so the whole system is balanced to work at its best. Today new cars on running on the ragged edge of overheating all the time with just barely enough radiator to do the job and will overheat with very little loss of coolant from the system as compared to 20 years ago.
The main issue is the overall surface area available in the small size of the cooling system of these compressors so to get the best transfer of heat from the metal to the coolant there is an optimal flow that is required for that to occur. The volume of the compressor is fixed so the flow rate is all that can be changed to gain the most efficiency from the system. The pump that comes with these compressor may be at the optimal flow rate but also may not be. Since the container that each person chooses to use is the radiator of the system it stand to reason that some will work better than others.
I will state that I am and always have been anal when it comes to the toys in my life so if it can be improved ( I have yet to find anything that cannot be improved ) it will be by me before I am completely satisfied. To be honest I am rarely fully satisfied and am always tinkering to make my toys better all the time. Just the way I am till the day I die.

Again at the risk of stirring the pot. If everything in a car's cooling system is good except the thermostat is missing, the engine will usually run cooler. Thermostats maintain temperatures where by you get the most efficiency. Please, do not worry about flow rate. It makes no difference in this application. If your unit runs hot you have one of 2 options that you can use in conjunction. You may increase the volume of cooling water and/or decrease temperature of the cooling water.
-
You're not stirring the pot. Just offering ideas. That's what such a forum is for. I'll still disagree with most of what you've said but that is OK too. Just as you know that flow rate is not important in this application, I know that coolant flowing too fast through a car radiator may not have time to be cooled by the available air flow and heat soak can gradually occur. I've seen that so I know it can happen. What is happening in this compressor situation is not as clear to me but I will always believe that flow rate is not optimal just because it is fast. Maybe it is optimal as set up and if it works for everyone that's all that is important. Hope yours continues functioning great for a long time.

No pot stirring to worry about here. But being a auto technician for 45 years I will disagree with you on not having a thermostat will make the car run cooler is just not true. I wish I had 100 bucks for all the cars I had to repair cracked heads or blown head gaskets from the thermostat being removed which lead to them overheating. The older cars ( 60/70s ) were less prone to it due to the cooling system being way oversized for its purpose with three and four core radiators being the norm. But in the 80s and up they stated downsizing every thing to save weight, production cost and fluid capacities. So those cars are much more susceptible to overheating from no control of the coolant flow when driving. Since the mid 90s the cooling systems are just capable of keeping the engine temps under control as long as they are full and all components are in place and unrestricted. Most all passenger car and truck radiators now are a single core of cooling tubes that are barely able to keep the cars temps in check.
Take the thermostat out of any new car and it will overheat in short order since the coolant will not absorb enough of the engine heat to the coolant or transfer enough of the heat to the air thru the radiator. Under hood temps as well as engine temps are much hotter now than older cars as well with 220 degrees being the normal cooling temps versus old cars being at 160 degrees. I am only going by 45 years experience fixing all makes of cars from the 60s up until the early 2000 models..
I also worked in a research and development facility as a durability technician and worked daily with engineers in diagnosing failures on Harley motorcycles. In my time there I helped develop the Vrod Harley engine and proved to the powertrain engineers that just because there cad/cam programs showed that the design will work in theory does not mean it will in execution many many times. Theory and physics are all required and necessary but are not absolute in application or execution.
Its what makes this country great is that we all can think and believe what we choose and agree to disagree with out fear of repercussions for the most part anyway.

You could just buy a cheap mini fridge and stick the compressor in that. Plumb the coolant water through a coil in the freezer. Would be quieter and cooler!
-
We can argue the point of thermostats all day but that doesn't help anyone on their compressor. The simple fact is that if you want colder head temps then the 2 surefire things you can do is increase the volume of your cooling water (as in go from 2.5 gallons to 5 gallons) and/or make that cooling water colder with ice or more frequent changes of that water. I do not wish to give speculation or beliefs, I don't post much unless I have on good authority that the advise I give will work. Of course there are times where I miss the mark but on this one, I'm not. Flow rate will do much less for you than the actual water you are using.
-
It's an opinion Jeremy and you're welcome to it but don't confuse it with a fact, simple or otherwise. You are not necessarily right about the compressor (although you could be) and I believe you are dead wrong as your view of the auto system shows you don't understand it but think that you do. Best of luck.

You are not necessarily right about the compressor (although you could be) and I believe you are dead wrong as your view of the auto system shows you don't understand it but think that you do. Best of luck.
I don't know why you keep insisting that what I am saying is an opinion. It's not my word, it is physics. You may experiment how you wish but if you do what I suggested you will have a cooler head temperature on your compressor for longer before you get to a point where you need to change the water for cooler water. To the point about the thermostats, I did say usually. If a car overheats with no thermostat it is due to another variable, not necessarily flow rate. The physics on the pump alone could make you go cross-eyed and when you add all of the other variable like the plumbing, volume, composition of the coolant, and so one things get deep quick. That is why engineers design these things to work optimally. You can figure all this out for yourself but if you want real answers on this, talk to a seasoned HVAC tech. Thermal transfer using a fluid is what they do and it is a very complicated thing if you go into it without prerequisite knowledge. I'm sorry to burst your bubble here but I am not wrong on this one and you'll do yourself well to do some more digging before you use the term opinion again. I don't see you offering a solution, you're speculating plain and simple and I might add that you're doing so with what seems to be very little knowledge to back it up.
I should have ended my last post with if the flow rate goes sufficiently low then you will have much higher head temperatures. You do best here leaving well enough alone as in the water pump and focus your attention to the water. It has the added benefit of not costing you any more money up front (other than the fraction of a penny for the 5 gallons of water you'll use from a tap, which for most of us is negligible.)
-
"That is why engineers design these things to work optimally"-on a forum that often discusses modification as much as anything. Entertaining. What you are stating is your opinion only and indicates to me that you don't understand the physics much like the automotive analogy. I would only change my view on that with verifiable hard data, not someones opinion. Could you be correct about the compressor? Yes but I think not and that is why the issue was raised. But keep on keeping on. My compressor functions fine for my needs and I'm not inclined to perform any experiments to verify. If you think that you KNOW what is accurate then feel free to prove it.
-
I think we've gotten way off track here guys, might be best if we all just let this go before Ken's post gets locked....
My High side filter has shipped! not sure how long it will take to get here(seller stated 20-38 days) but at least it's moving toward the US ;D
Should get my Ebay sieve today. It will be prepped and waiting for the filter.
-
A voice of reason. Thanks and let's let it go.
-
Well my guppy tank needed some air so I decided to fill it back up. I have the tuxing so secondary head is different.
What I found was varying the flow did nothing until it was restricted so much temps really started to rise. Unrestricted, the tempo dropped back down.
Average head temp was ~42*C being 62*F out. I verified with an infrared thermometer and the difference between the two sensors is negligible.
The majority of the heat comes from the first stage compressor where I measured 70*C average. I believe heat soak is coming into play here. I think adding increased air flow over the first stage would help temps.
Again I have the tuxing and heat hasn't been an issue yet. With the different designs I can't test anything that would be applicable to the yong heng. Hope this helps somehow though.
-
The Tuxing has the advantage of a very much larger volume of water in the head itself. The Yong Heng style will benefit from a greater flow to make up for its lack of volume.
You're right about that first stage. The amount of heat coming from the 1st stage pressure release is very high when I got to tighten or loosen it up. Haven't measured it but it can be almost too hot to touch.
-
Jason, that is my current plan for additional cooling safety margin-an added fan. Especially since as noted earlier the hottest spot on my Tuxing is always the SS line running from top to bottom of the upper cylinder (maybe better to call it the head) but that line does get very hot (water dropped on it will sizzle off). I haven't seen sensor indicated temps above upper 50'sC using room temp water with WaterWetter added but anything to remove heat should help extend useful life. I don't run the compressor for more than about 3 minutes max for my current filling needs and usually 2 minutes or less to top off the largest rifle reservoir and well less than 1 minute to top off a pp700 pistol. Certainly adding ice to the water should help as well. I have a couple of PC power supply fans around the shop and plan to add a bracket to hold one blowing on the cooling fins and head as much as possible.
-
Ok so after a few more run times and a few experiments...using the included pump in a bigger container of water 10gal instead of 5gal and slowing the included pump from full flow to about 3/4 and an additional personal fan of maybe 6-8in diameter blowing directly on the head of compressor overall temps have dropped... Next i am going to try to use a cooling additive and see if it helps any more... I believe everyone here has good ideas as far as cooling. i think its going to be finding a system that will work for each individual compressor overall i am very happy with the unit for the price and my use i will continue to try keeping it cool the best i can just for a longevity stand point...i will update with anything else that may help better or worse....still happy with performance beats hand pumping... awaiting for my chinese drier....lastly is there anywhere good to pick up decent molecular sieve material
Thanks guys

I've seen people buying it from eBay. I purchased a smaller amount from Amazon.

The 13X medium is what I bought for use with my shoebox since it has the highest absorption rate for H2O only and does not readily absorb other chemical vapors. In the shoebox system there are no chemical vapors to worry about if you use an oil less first stage compressor. So all that's in my HPA filter is the 13X medium. In these Chinese compressor that use oil lubrication it would be wise to add about 1/4 of the internal volume of the filter with activated charcoal to capture the chemical vapors. There are also other molecular mediums that absorb both H2O and chemical vapors such as the 3,4,8A medium so its up to you how you compose your filter medium to suits your needs.
Just one more bit on the discussion of cooling system design. That is if the engineers are so good at designing the system in car bikes and HVAC. etc there would be no need for actual real world testing since they would be perfect right from the get go. So I guess the 11 years I spent at Harleys test facility doing durability testing of the full vehicle was just a waste of time and money on Harleys part since the bikes were perfectly designed from the start. I guess the numerous design flaws we uncovered in testing in real world conditions that allowed the engineers to revise or completely redo their design was not needed. One has to keep in mind that computers. the programs they use and the people using those programs are humans in which can and do make mistakes or miscalculations that in the big picture and real world are flawed. So as such testing to prove or disprove the theory or design is and always will be required to be performed to validate any and all engineered systems.
There I have said my piece and will now let it be.

Mike,
Since we are not breathing the air, why worry about the oil/chemical vapors? other than tiny whiff of smelly air when you bleed the fill hose, what risk does it pose?
-

John
The risk is that there can be petroleum vapors that are transferred into the tanks or guns air tube that could combust under the High pressure that would create a very dangerous bomb waiting to explode. Its not safe or wise to not try to capture as much of any flammable vapor as possible when compressing air to the pressure we use for our guns. research the composition of the mediums used in the diabolo filters that go for 300 plus.

Mike,
Forgive me If I'm just not thinking this thru...
If these vapors posed an explosion risk, would they not do so during compression??
I do understand, petroleum products in the path of the in coming high pressure air pose a risk for explosion.
-
25 years before I ever fooled with PCP's we had N20 and O2 tanks in offices. It was always hammered in to us to only use silicone on the threads since any combustible material that reached the high pressure area could lead to explosion. I personally don't want any amount of chemical residue building up in the system that can be avoided. I guess some is inevitable but how much would it take to trigger combustion/explosion? I don't know and do not want to find out.

That is a good question and do not really have a good answer for it. Just know you need to try to capture it before it gets to the tanks or guns. The 13x medium will not absorb it very well so that's why the need for charcoal or other medium designed to absorb those vapors.

Once all said and done about quality of the compressors on ebay I might order one if I think it will last me a long time (with normal maintenance) but for now I'll continue going to the dive shop for $5 for the large tanks to 4500psi.
-
I bit the bullet today and got one for 312.00 bucks shipped but I live 1.5 hours from the nearest dive shop so I will try it out. Sick of hand pumping it has to be better to fill a gun up.
-
Are not automotive thermostats used to regulate flow/temperature of coolant only there to disallow an over-COOLED temperature? They are there to allow the coolant to reach operating temperature. No thermostat, the coolant may never get up to the desired HEAT set point. Regulating the flow of the coolant in a car does not make the coolant cooler. The thermostat can only get to maximum COOLING of the coolant at FULL OPEN. If the thermostat closes, the flow slows down in order to HEAT the coolant back up to keep it at the desired HEAT. Ya'll keep talking like the thermostat closes to give better cooling of the coolant????????????
-
What kind of oil is recommended for these compressors?
-
Yong Heng recommends VG46 hydraulic oil, which I have aplenty at work. Multiple 55gallon drums but there are petrolium distallates in it so I don't want to keep using it for long. Everyone recommends VG150 oil which gets expensive, but not prohibitively so in my opinion. I may go that route. I'd bet the VG46 will be fine, though.
-
I appreciate the info regarding the sieve material...and for wayne52 i also was a little skeptical about the compressors and did allot of reading and looking into the units before purchasing and i can say that i am very happy i did...my drive to fillville was also quite a trip and i found myself going more and more....being the price and i got enough rebuilds in case anything should happen that it should last awhile....i haven't had it more than almost a week now but...the experience has been good with seller shipping and am overall happy with the quality....while the main thing like has been discussed now is keeping it relatively cool and get a external drier for it....as far as oil it is recommended iso46 but i have read numerous different oils used now with success iso46. Synthetic compressor oil chemlube 751....personally i used a cheap compressor oil to run as a "break in" and did a good flush of it before using the chemlube just to get rid of any remaining gunk from factory etc.... Overall a good option for the average shooter to get rid of a hand pump or save from driving to fillville...sorry to get long winded on what seems like nonsense...
Lastly i will update cooling has gotten much better final usuage was additional fan on compressor 10gal water container and pump on 3/4 flow and ice packs in water kept it in low 40c for the same time it would get into 50c
Thanks guys for all the help and great info on compressors
-
How long these compressors will last is a question at this point but I sure do like flipping a couple of switches and quickly having a full gun. I have a 50 gallon air compressor in my shop that I bought about 6 years ago because it had wheels and I could move it around where needed. It has the same or at least very similar motor (by all outward appearances) as the Tuxing compressor and has been used quite a lot over those 6 years. Obviously no HPA section which would seem to be the most likely location for problems to arise but the motor has been fine for many operating hours.
-
Biz we agreed to drop this but you're right. I use chemlube 751 and still see signs of dieseling. YMMV. I'd recommend molecular sieve and activated charcoal on the output.
-
Yeah, I've got the 13 sieve stuff recommended here from Ebay. It wouldn't be hard for me to cut a piece of my aquarium filter to fit between a layer of activated charcoal and the sieve. I'm using that big golden high pressure filter as most are. I may still go over to chemlube 751 but we'll see...
Right now I'm stuck in the water as I don't have a way to fill my Chinese Acecare SCBA tank. I have the valve and fill whip but not the filling valve. I suppose I could use a male - male foster and go in the reverse direction with my fill probe on the tank but I don't have one, the weekend is upon us and the unit I have on order from Aliexpress seems to be lost with USPS. Daaaaaaaaaamnit! :'(
No stores, not even painball stores locally have what I need. Industrial hose fitting stores may have them but are all closed on the weekend. I'll probably have one made at work or just order up from Amazon but there goes my entire weekend. I so wanted to play with my compressor and tank this weekend.

Adding a little activated carbon to the filter will be easy, why not....
$10 worth of aquarium activated carbon should last for 5-6 media changes, maybe more.
Does anyone know the thread size on each end of the gold Chinese filter? I'm guessing 1/8"NPT for both ends?
Reason I ask. I'm thinking of adding a 6000psi needle valve at the discharge end of the filter. This way, during start up, I can close off the needle valve, allow the filter to pressurize to say 2500-3000 psi. since my tanks will have 2000psi or more already, once I open the needle valve, I'll have some dwell time for the start up low pressure air to have dried in the filter and the back pressure from the tank needed to keep it that way during the fill...
Still looking for a 1/8"NPT,6000psi needle valve... I've found many 1/4". At worst I'll use a couple of bushings. Just need to know what thread size the filter has at each end.
-
1/8 npt stuff is tough to find for our needs, at least in my experience. I made a reg tester and bleeder from all 1/4 npt stuff and the just used a reducer to get to the 1/8 for the bottle connection. I wanted to add a better gauge for comparison reasons and had to machine an adapter for m10x1 to 1/4npt.

John, I was thinking about the same thing except I want to also place a valve on the input end of the filter because it takes an additional 2-3 minutes to pressurize the filter when empty after bleeding the lines. That would also require a bleeder on the discharge end of the filter. When will all these MODS end ??? Bob
-
Bob,
I hope the filter, and what ever it takes to get it right, ends the Mods... probably not though ;D
Maybe a fancy paint job on the case? Intake air dryer? Actually thought about drying the intake air.......

Restricting the intake has a serious negative impact on the output.

The threads on the gold filter are BSPP not 1/8 NPT so you would need a adapter bushing to go from BSPP to 1/8 NPT and then a 1/4 to 1/8 NPT bushing to add the needle valve to the end of the filter housing. I have a 6000 psi needle valve on the output side of my filter but just used two bushing to reduce to 1/8 NPT with two male foster in each end of the needle valve. Then I have it in the end of the fill whip that comes with the filter with another fill whip from it to my tanks or guns. When filling I close the needle valve to allow pressure to build to 3000 psi before opening the valve to fill a tank or gun. Filling a tank is not a problem when bleeding the HPA since I just close the needle valve before bleeding the pressure off with the tanks bleed valve. To fill a gun and bleed the pressure I have a modified scuba tank K valve block that would normally attach to the valve on the scuba tank but instead I modified it so it has a female and male fosters on each end with the clamp part cut off the block. So it is put in between the fill whip and the gun to bleed off the pressure with it after closing the needle valve to retain the HPA in the filter for more filling during that days filling routine.
I have a shoebox right now so it takes 15 to 20 minutes just to pressurize the filter so the needle valve helps me fill faster by not losing the HPA in the filter when switching from tank to tank or gun to gun.

I'll have to remove the cooling fan though as it's just gonna battle AGAINST the motor housing cooling fan that vents out the front and blows past the 1st stage pump. Obviously I have only used my compressor once to fill my Taipan and didn't even study its workings. So, fan will go or adapt it to fit otherwise.

Thanks for the link the fan verifies the the pump is working. Had the water pump stop working on me when I was filling my gun. Happen to look into the bucket and the pump quit working. Somehow the pump lost it prime. It fine now but I still would like to know that the pump is pumping
-
I was gonna just roll with keeping the return tube up above the water line to be able to see the water flow but in a deep 5 gallon bucket it's not so easily seen so the flow indicator I found to be a must. I knew I already had fittings from my pc set up. You've gotta make sure your fittings/barbs will work with the tubing or else you'll have to improvise.
Regarding the pc cooling fan, not only will it be battling the motor's cooling fan as it vents out the front on my Yong Heng but it also bounces all over to high Heaven so that won't be working out either. And that first stage tube gets HOT within seconds and it'll probably melt the plastic fan housing so yes, it'll be going bye bye. Also the way the feeding water tube rests on that same lower low pressure pipe, that'll probably melt too so I'll be finding a way to tie it out of the way. I haven't tried just tightening the water fitting on the pump head so that it angles up further. Not sure what type of joint compound they used, whether it be just red rtv sealant or even RED LOCTITE. I don't want to ruin the seal so I'll just tie the hose up so as not to touch the hot air tube.
Anyone know what sealant the Yong Heng is using on the water fittings?

Bought this fan on fleabay

Comes with barbs. Good deal. Make sure when you get it that the fins travel without restriction. I've read many accounts where the workmanship is shoddy and the fin is mounted crooked so it impedes flow. And just for the sticklers, a it's a flow indicator and not so much a fan. 8)
You shouldn't have to worry about leaks as our submersible pumps are rather weak. My barbs have o-rings. Not sure if the one you listed does or not. You're gonna love having visual indication of your flow from here on. I'm sure you're rather weary as you've had your pump lose prime once already. I hope you caught it quickly so no damage occured!
ETA: And that just got me thinking. I had planned on devising some sort of vertical cart setup to keep a small footprint. My choices with that are to mount the water above the pump or below. Above I'd be worried of a leak and shorting out my compressor. Mounted below will put undue strain on the submersible pump and may or may not have enough oomph to get the water to defy gravity. I think perhaps side-by-side is my only other option or get a stronger pump. I don't want a stronger pump because then my rinky dink water flow indicator set up my blow its hoses off. Not really, but I'd rather not go with a stronger pump. I've already heard it mentioned that the hoses don't like to stay on the barbs without some sort of hose clamp. Mine are tight now, but who knows in the future how they hold up. They should be fine as-is though.
-
What about another, similar flow, pump on the output end pulling instead of pushing like in the original configuration? Maybe that will help push the water uphill.
One thing that needs to be taken into consideration is the output water temperature. It could warp the flow meter plastic or the pump I just suggested.
So maybe that's not a great suggestion in hindsight lol ;)

I can't wait to buy one of these compressors and start adding gadgets to it.. :)
My wife told me that I have to get rid of something in the basement, before I can buy any new items.
So, while I'm making up my mind which piece of unused exercise equipment to dump,
I got out the Hill Mark3 stuff, so I can try to fix it.. I looked at my 1-13-2014 cost.
It's $314.94, almost exactly the same as eBay item number: 262943287446 Yong Heng shipped from LA..
If I can fix this, maybe I can sell it! ;)

I can't answer much as I haven't run this more than 3 minutes. The real test for me is to fill my 2.17liter tank. I'm not sure how hot things will get but I like to tinker while I wait on my adapter. I don't believe the water will get any or much hotter than what my water-cooled pc got up to. That processor gets blazing hot and with a small self-contained cooling setup with less than a liter of water in it, it the acrylic handled the heat fine. And when I do go to fill my tank, I'll be using either ice from the fridge dispenser or half gallon jugs of water frozen or even blue ice packs.
I'm sure things will be fine. All you others are fine with simply using tap water and replacing it when it gets too hot. With the ice I imagine I'll get through a long run without any problems, except that I may replenish the ice midway through as I'm sure it'll melt rather quickly. I bet I'll end up using gallon jugs of ice frozen and removed from the jug it was frozen in.

Bizill, have you checked the pump to see if it will easily lift the water. My Tuxing pump lifted the water to the head inlet 2 feet above the floor. I have a 12" deep toolbox that I use for the reservoir and a 110 to 220 converter running my system and have a rack being made to sit it all vertically to lessen the floor space as you noted. I sat the compressor on a foot locker to get it to the approximate height I wanted for the stand (converter on top, compressor in center, and reservoir on bottom) the last time I filled and could see no change in water flow-still very fast. The Tuxing does power the pump from an outlet on the unit itself but surely it is stepped down to 110.

Bizill,
Do you know if the compressor head has water flow directors like the cpu water blocks I have seen? If there aren't any the water may not be flowing evenly and thus not cooling evenly?
The one other thing I remember with cpu water cooling was corrosion. It would be prudent to add a corrosion inhibitor to the water. Automotive antifreeze would work but it's poisonous and reduces the thermal conductivity compared to straight water.
Water Wetter and Purple Ice have corrosion protection and increase cooling performance.
Taso

What about RV antifreeze. It's meant to winterize the fresh water system and isn't toxic.

Eric,
Straight water cools better than antifreeze. Water and Water Wetter or Purple Ice is even better than straight water.
Unless you will be running the compressor below freezing temperatures. ;)

-
Speaking of pc cooling, I wonder if a similar system would work. Maybe a cars oil cooler plumbed in with a pc fan over it.
Maybe not. I don't think the water gets warm enough to need a radiator to dissipate heat. Possibly put the cooler on the compressors inlet side and put an ice pack over it. That should cool the inlet water quite well.

For $30 it could be worth a shot.

You could try to put something like this in line with the discharge side of the compressor to reduce the discharge temp, add 2 120mm fans to force air across the radiator and you may not have to add ice or change out the water...

Haha yeah we did. It's cheap enough to be feasible. My compressor doesn't get too hot so I'll leave it for the other folks to experiment. Then again maybe not... If I get bored at work I may just buy one.
Couple your radiator with two of these

I don't think there is enough temperature difference between the ambient air, 80°F and 60°C=140°F head temperature to make a difference cooling the coolant with the radiator. Plus no one has measured the actual temperature of the discharged coolant so it should be less than 140°F.
I think that two containers with water/performance additive mix would work the best. Start with one and when it gets close to 140°F, for example, move the pump and output hose to the other room temperature bucket. Reusable ice packs couldn't hurt.
140°F head temperature really isn't that hot. The 1st stage where someone said water sizzled on is where I would try to cool next. That heat is definitely being transferred to the next stage.
Taso
-
bandg, I believe there's enough power to get the flow overhead. I haven't even tried but I think it would be fine.
I have available a 2 cooler fan size heat exchanger that's not being used but I'm just gonna go with ice in the bucket. As far as flow around the head, I believe it's just a crappy aluminum heat sink, the type that comes on older fan-cooled intel I7 processors. I've seen a pic and I'm thinking it'll work pretty well with the small volume the head's given compared to the larger Tuxing head. I don't think there were "channels" per se, but from the looks of it a lot of turbulence will be created in the water flow and that will aid in heat transfer.
I went looking for a picture of it but cannot find it. I thought I read it on the TAG forum but may have been one here on GTA.

You better believe it. Like I said, I won't be keeping my pc fan mounted and touching that lower 1st stage line as it's HOT. If I touched it any longer I'd burn myself. This was the reason I initially wanted to go with the Tuxing setup. Their big head water cools the lines from 1st to second stage where as the Yong Heng does not. Yessir that heat is being transferred. I don't see any good way of water cooling those exterior lines on the Yong Heng but some kind of aluminum heat sink might help but probably not as the air travels so fast through it that the hot air will never be cooled.
-
I'm looking at pictures of the aluminum cylinder on top of the Yong Heng compressor,
and I assume that's the water-jacket HX (heat exchanger).
It's got some surface area where there aren't any connections,
and maybe a fin-type heat sink could be added..
I just googled 'heat sink for cylinder', images and there are a bunch of designs.
Even a solid aluminum band (no fins) heat sink could slow the heat saturation process..
-
You could probably find a auto trans oil cooler at a junk yard cheap and it has round tubes like the hoses so no restriction of flow like a flat tube radiator would have and easier to connect the hoses to as well. With a fan on the cooler it would work well but best if its on the inlet side since no help cooling the outlet flow that just gets dumped back into the reservoir.
-
Bizill,
I don't have one of these compressors so I'm trying to find pictures online. Does your compressor have aluminum water separators on the left and right side when viewed from the front? Is the bottom black finned case aluminum or iron?
Maybe you can cool the aluminum water separators somehow. Could you create some kind of shroud around the bottom black finned case to direct cooling air through the fins? Maybe flipping your fan to draw air away from the fins? Maybe if you got a head start on cooling the bottom case it would not reach the plastic melting temperatures you're seeing now.
I did find a youtube disassembly video of the compressor with the large diameter gold head. But I can't tell how the water flows through. All I see are these chrome cylinders.
Thanks,
Taso
-
Yes, I have the dual water separators. I'm not going to worry too much about the first stage anymore. I really don't see any feasible way of cooling that compressed air. I know that large 2 stage industrial compressors have cooling fins on them but not sure how much they help. Now if I were to somehow place aluminum washers on the tiny compressors pipes it may have the same effect, but the air travels so fast through there that I don't think it would cool the air blast much, if at all. No really good nor cost-effective way to water cool the lines. I wouldn't want corrosion either. I'm not sure what steel is used for those high pressure lines. Stainless steel or some other type of metal???
I'll try to learn more when I actually get to using this compressor for more than a mere 2 minutes at a time. I'd love to cool the air but don't think that's possible. I do remember reading and seeing pictures where some places put your scba in a water bath whilst filling. Perhaps that's something to look into. But isn't that only done to get complete filling vs losing psi when the bottle comes down to ambient temp? I'm still getting my learn on and have much to learn it seems.
-
People with the yong heng could try swapping heads.
https://m.aliexpress.com/item/32796351747.html?spm=a2g0n.orderList.0.0.T3Q394#autostay
I do have a spare I may be willing to ship someone just to see if it fits and works.
Taso, I think the radiator will work well especially if ice is placed on it or a damp towel with fans. I'm going to measure the tubing id and purchase a radiator when I get home.
-
After noting the post about the added external fan fighting the flow from the motor fan I'm thinking leave the lower cylinder as is since it has the air flow from behind by the motor fan and mount the PC cooling fan on top of the enclosure (maybe on the carry handle or using one of the handle screws) blowing forwards across the upper stage and the hottest line.
-
After a few hour of running time on my compressor and being worried about it's longevity do to overheating, I just ordered a radiator for the cooling lines and will be adding another cooling fan. Presently I have been using three freeze packs to the cooling tank which does help. On a hot day and after 5 minutes of running you can watch the head temperature rapidly rise from 28 deg C to 60 deg C in a matter of minutes. If it starts to run hot I shut it down and allow it to cool. The problem is that you have to bleed the air from the output side because the compressor does not like to start under a lot of head pressure and if you have a large filter, in the output, it starts to overheat as you are pressurizing the filter. My goal is to keep it cool to avoid shutting it down. The main problem is that this compressor has greatly spoiled me because I HATE hand pumping. When I can keep the pump cool I'll be cool. Bob
-
Bob, I ordered a radiator as well. The hoses are 3/8" ID. Also adding a valve on the inlet side of the filter would allow you to only bleed the fill hose while maintaining pressure in the filter. Just a thought.
-

Jason, that is exactly my plan and I am now in the process of selecting, from McMasters, a HP valve and fittings. Bob
-
Bob,
I really don't think a radiator is the answer here, I may be wrong though.
Before I went to the trouble and cost of adding a radiator, I try ONCE thru cooling. Get a couple of fittings for either a faucet or hose hook up to the intake side of the cooling head. put the discharge side in a drain and establish a flow about what the little pump currently does. If temps start raising, increase flow. Of course, the colder your tap water is the better.
I do think adding more cooling air that doesn't fight the fan on the motor is a great idea. Removing as much heat from the first stage as possible by increasing air volume across the fins has got to help..

John, You may be 100% correct; but I think that anything that will extend the intervals between shut down and start up because of overheating is worth the try.
I will also take your advice in using a fan to cool the first stage. I have been thinking about adding a thermistor plus circuit, for auto shut down if over 65 deg C.
I know, I'm overthinking it but I want to keep it going efficiently . Bob

Just a clarification of an earlier post about the thread size on the ends of the gold Xin Yong Shi HPA filter. Mine has M10 x 1.0 non-tapered threads. My Xin Yong Shi hand pump also uses the same thread size for the fill whip and quick disconnect. Most of the stuff coming out of China uses M10 x 1.0 for the fill whip/QD connections.
-
Robert,
THANKS!!! boy was I wrong, I would have never guessed 10x1.0 threads....
Time to empty my Ebay cart, NONE of the fitting's I had in there will work :o

On Friday I received my 110V Yong Heng pump that I ordered from Ebay 5 days prior. It was superbly packaged and included a rebuild kit of o-rings and piston rings. I filled it with synthetic compressor oil and let it run for a few minutes unrestricted and then connected my gold HPA filter with the end plugged and let it fill to 4500 psi. Everything worked fine with no leaks. I then filled my 30 minute SCBA tank from empty to 4000 psi. I did this in 500 psi intervals which took about 5 minutes per run and a cool down/line purge after each run. Keeping the unit under 50C was a challenge but I was able to accomplish it by using a 5 gal bucket filled with water and the entire contents of my refigerator's ice maker. The temp stayed around 47C as long as I had lots of ice in the bucket. The tampon in the black HPA filter that came with the compressor did get brown on the input side but stayed white on the output side. The gold filter did not appear contaminated. At the end of the fill session I again ran the compressor with no restriction to purge any water from the internals. As others have noted, the air lines that connect the various stages get very hot and I'm thinking that some type of fins attached to them may help dissipate some of the heat. I plan to use the compressor for topping off my SCBA's from 3000 to 4000 psi so my runs should be much shorter from here on in. So far I'm happy with the unit.
-
Bob,
I don't have much run time on my compressor because I'm still waiting on my high side filter to deliver...
It's starting to sound to me like, the heat issues, are caused by heat saturation of the ENTIRE cooling system.
Once the cooling water gets to a certain temp, it can no longer remove enough heat to make a difference. Adding a radiator may extend the time it takes to reach this point some what. Once thru will do so indefinitely given cool enough water and sufficient volume coming out of the tap. Only, IF the head is efficient enough to keep saturation from occurring given enough cooling.
I'm beginning to think, the cooling head is NOT efficient enough to deal with ALL the heat. So, adding more cooling air, that doesn't fight the existing motor fan, cooling the first stage and case, will also extend the time it takes to reach saturation, maybe even stop it completely...
Given enough cooling air and water, at some point, you should hit a temp that will stabilize, removing the ability of the heat generated to saturate the cooling system. Figuring out the combo that it takes to get here is the question....
-
I had thought of mounting my pc cooling fan right in front of the handle on my Yong Heng as bandg had mentioned but it's already bulky to carry at the moment to placing a fan there for me will be a no-go. If I devise a carrying rack on wheels, maybe. But for now I'll just use a small desk fan to blow on it and may not even do that.
As far as cooling the air lines, one would need to disassemble the fittings and simply add washers of the perfect inside diameter to fit tight to the tube but those washers will not stay but with as much as this thing vibrates. You could add tubular spacers between them, I suppose. Or I'm sure there are two piece heat sinks that would bolt together to fit somewhere on the internet but I don't really want to screw with the lines. It might help but by now I'm sure there are thousands of these compressors in use across the globe with nary a problem so forget the additional effort. I think tentatively I will just be using a large volume of water with ice and a small fan to blow across the entire compressor and I'll be golden as my golden high pressure filter. :P
-
As stated in my past post, using the yong heng compressor as is has worked for me since April and gets used almost every day filling my guns that I shoot. I'm going to add the inline flow indicator as I have experience the water pump lost its prime. It is primed again and I think the flow indicator is a go idea to have. I have a clip on fan that I'm going to try to see if that made any difference. So far the compressor is doing the job for my needs. Glad I took a chance and bought this little compressor. If mine decides to go south, I would not hesitate to buy another as they are priced about the same as buying a hand pump. For now this compressor gets used more than my backup omega super charger which is on standby. If the super charger fails then I still have my hill pump to fill but that is my last line of desperation to fill and shoot😳 Going to the dark side is costly but worth it😎
-
Think I'll also stick with ice/ice packs for now. Seems to do the job and the fridge makes it while I sleep.
-
Ok guys i have noticed the first problem on my compressor....the aluminum block on the high pressure side is very soft as im sure everyone is awarr of...anyway when i removed the hose to teflon them i i spected the threads in block and the first couple threads seem to be cracking and upon threading the hose back in they started to spiral and pull out as i was snugging the hose...i didnt over tighten or cross thread i am trying to get in touch with seller for a new piece if they will even send one...just to spread the word to keep a eye on yours...hopefully they will send me a new one
-
Wow! Weight: 47.60 lbs is a little heavy for such a tiny package..
Since these pumps are shipped without oil, does that mean they have never had any oil in them?
Does this mean my new compressor has never been tested at all?
What's a good (and cheap) oil to use as a Break-in / clean-out oil?
Thanks,
Rich
-
Can't speak for all of these Chinese compressors but the Tuxing I received did have residual oil in it. I had some small flow out of the drain plug so I removed the motor front cover and cleaned it out prior to initial fill and running. The only reason I can see for that oil presence is that it was tested prior to shipping. The Chemlube 751 that I put in mine initially is still completely clear after probably 45 minutes total run time.
-
Richard,
As bandg said, my compressor had some residual oil. I pulled the back off the case, wiped out the little bit of oil and looked for and big stuff that might be floating around.
As for break in oil, I just used DeWalt D55001. It only takes about 300ml to fill the case on the Yong Heng. So, the quart of oil I bought gives me the break in run and 2 oil changes...
My break in oil is also clear after about 90 minutes of running.
-
The seller I bought from said all units are tested before shipping. So mine had oil in it for testing. I filled mine and did some fills then drained and refilled again to flush out what ever residual oil may have been in it.
-
Oil was used to test mine and then drained for shipping.
-
I did some more reading and did finally decide to go with Chemlube 751. Expensive as &^^& for a guy like me but takes one less worry out of the equation and with a worry-wart like me, that's priceless..
http://www.ebay.com/itm/232075922209#shpCntId (http://www.ebay.com/itm/232075922209#shpCntId)
Went with the gallon size. Hmmmm, ISO46 hydraulic fluid (Chon store/manufacturer recommended) FREE from work vs $76 shipped for the proper compressor oil... I'm crying.
-
I was just looking at the Chemlube 751 data sheet and it looks like it's used for vacuum pumps too..
(missing p after tt) htt://pdf.ultracheminc.com/CHEMLUBE_215-229-230-501-751-822.pdf
That's interesting, because I buy oil for my HVAC vacuum pump and have some on hand..

I have the Robinaire as well but I noticed on the sds:
Petroleum distillates,
hydrotreated heavy paraffinic
64742-54-7
Taken from Crosman: So if a product has the warning "Contains Petroleum distillate" that is red flag that is should not be used in our air guns
Chemlube 751 is a diesther. I have no idea what it's derived from, heck may even be derived from petroleum distillates, I'm no chemist and I'll have to look further but it seems on the surface Chemlube is healthier for our guns and bottles. I think this may have all been answered already but I'll have to read more. For me, Chemlube is the way to go.
I gotta read this when I get home... http://www.machinerylubrication.com/Read/30730/base-oil-formulations (http://www.machinerylubrication.com/Read/30730/base-oil-formulations)
"Diester (dibasic acid ester) is manufactured through a reaction of dibasic acid with alcohol. The resulting properties can be adjusted based on the types of dibasic acid and alcohol used."

Let us know what you come up with. I want to do the same thing.
Also thinking a combination shutoff/bleed valve at the outlet side of the filter' That way I can maintain the pressure in the filter & bleed the line to my Prod.
What about a shutoff valve with a male foster fitting on one side and a female on the other.
-
Thanks Robert and Bizill I've been looking at that Lube-V and it seems a lot like Chemlube 501.
Which is close on the chart to Chemlube 751.. The price for Lube-V seems to be in a lower orbit too.
I'll order some tonight, and see if it gets here before the compressor..

I really dont get it, people put hundreds or thousands on airguns and then going cheap on the oil?
I use the best oil for what is needed, oil quality vs machine life. And then still change more frequently than the manual says.
Oil is the least expensive part of this hobby.

Eric's setup looks all patriotic with the red wagon, white pail and blue compressor. LOL. We'll call the gold filter the flagpole being that it stands vertical.
I'd still venture a guess that the recommended oil being VG46 will keep the COMPRESSOR running just fine. As far as oil blow-by, that might be the kicker. Hence I finally opted to go expensive. Even then I think it's just crossing T's and dotting I's. I still bet that there are thousands of these compressors world-wide feeding small, medium, large and airgun tanks and I haven't come across any issues with using the less expensive oil. Just don't use straight dino oil. I could be wrong and err on the side of paranoia but eventually in the end the expensive oil does make better sense.

I'm 71 years old and have at least five age related ailments. So, I've changed the way I buy things.
If it's going to cost more and last over 10 years, I'll try to find a product that's only going to last 10 years. :)
If I was younger and wasn't retired and living off a very low income, I would have purchased a top of the line compressor,
not the cheapest model on the market. (Cost is the same as my 2014 Hill hand-pump)
I do not plan to pump up my scuba tanks. My plan is to use this compressor just to top-off my PCPs.
The first time my HVAC vacuum pump fails to pull a 50 micron vacuum, I change the oil before using.
I also change the oil in the 2012 Prius C2 every 10,000 miles. Which might be every 2 or 3 years..
(Amazon has Mobil 1 120758 Advanced Full Synthetic Motor Oil for 0W-20) :)

Anybody know how many amps the compressor pulls esp at startup ? I'm off the grid and plan using a generator. I have a 2KW inverter generator which is most ideal to use as it is very quiet. I can go to a much bigger 10kw gen but sure is noisy.
Again thanks.
-
I haven't tested mine for draw but the Yong Heng manual states they want 8 amps available. Seems low but could be accurate.
-
I'll drag out my Honda 2000 inverter and try it out today.
I'm using Chemlube 751 in my compressor.
-
Thanks for the help on the inverter generator issue.
Was also checking the hydraulic oil required. It seems Walmart carries the Hydraulic oil. Back in the 80's, I worked as a lubrication engineer for Texaco in the Philippines. For industrial compressors, our default recommendation was Automatic Transmission Fluid even if the compressor manufacturer recommended something else. If I remember right, ATF is a more premium oil than hydraulic oil. It has more dispersesant additives keeping dirt in suspension.

First post, been lurking for a while. I just took delivery of my yongheng compressor and I gotta say, I'm Impressed! I , at least for now only use it to fill guns..not bottles. Like others on here had a hard time deciding on oil, I feel the chemlube 751 is too thick. From all my reading it's ISO 150 is equivalent to a 30-40 weight oil while the recommended ISO 46 is more like a 10 weight. I did try royal purple ISO 100 compressor oil which I think cross referenced to chemlube 501 but ended up going back to a 46 viscosity vacuum pump oil by supercool. Anywho...completely satisfied as of now for price paid. With a plug in the line when not in use I keep it charged to 1500 psi and it holds steady with zero leak down. It was purchased on eBay from "solar jean " for $320. It has since gone down to $315 and now ships out of California.

Anywho...completely satisfied as of now for price paid. With a plug in the line when not in use I keep it charged to 1500 psi and it holds steady with zero leak down. It was purchased on eBay from "solar jean " for $320. It has since gone down to $315 and now ships out of California.

Enjoy your yong heng compressor I know I am😎

Kris,
Post up a link.
An eBay link on compressor?
Don't know if I'm ready for posting links...lol.
Also, on eBay it seems they charge the same for 220 or 110. On allieexpress they seem to want to hit you for an extra 40 or so.

I bought from this seller.

Ordered on Sunday, delivered on Tuesday. Keep in mind, I'm only 300 or so miles from LA....
DHL notified me my high side filter will deliver today! I have all the stuff to assemble it, plan on a test run tonight.
EDIT:
Almost forgot, been following the Air Venturi compressor thread. On the subject of heat, I know the compressor is different than our yong hengs and tuxings. but. I found it interesting, the AV has the factory thermal shut off set for 95c. One of the posters ran his for I think it was 30 minutes, compressor head was at 71c when he shut down....

I ordered my Yong Heng from this seller last week: http://www.ebay.com/itm/220V-110V-30MPa-Air-Compressor-Pump-PCP-Electric-High-Pressure-System-Rifle-/182559800584?hash=item2a81697d08 (http://www.ebay.com/itm/220V-110V-30MPa-Air-Compressor-Pump-PCP-Electric-High-Pressure-System-Rifle-/182559800584?hash=item2a81697d08)
It was delivered from California to TN in 5 days and was really packaged well.

Anybody know how many amps the compressor pulls esp at startup ? I'm off the grid and plan using a generator. I have a 2KW inverter generator which is most ideal to use as it is very quiet. I can go to a much bigger 10kw gen but sure is noisy.
Again thanks.
Saw this in the Ebay specs.
Voltage:110V for US/CA/MEX;220V for EUR
Power: 220V-240V 50HZ or 110V /60HZ
Motor Power: 1.8KW
If the motor really is using 1.8KW, using my local line voltage 1800w / 120vac = 15 amps.
If they send me the high voltage model, 1800w / 240vac = 7.5 amps..
If I had your gens, I would start off with 10kw and measure the amperage while topping off a PCP..
If it's around 1200w, you could try it on the 2KW inverter generator.. But, if it has an inverter
like you use for solar, those FET transistors could burn up on compressor start-up..
I've seen motor start-ups that dim the lights in the house, and a little in the house next door!
I've forgotten anything I've ever learned about trying to find AC motor surge current..
http s ://en.wikipedia.org/wiki/Inrush_current#Motors
I know that HVAC installers use special breakers that won't drop out on a very short pulse of extra high current.
But those breakers have the Grid behind them, and you don't.. :P
I think, most home sockets for 120vac are limited to 15 amps by a fusebox or a 15A breaker.
The 120vac 20 amp sockets have a little 'T' shaped slot for the (N white wire).
(google 20-Amp 125-Volt Indoor Duplex Wall Outlet and look at the images).
I think the 10KW gen is most likely the safe way to go..
Cheers,
Rich

My 2000 Honda inverter gen set won't run it at all.
Mine was converted to run off of propane.
Guess I need to look for a larger generator.

Ok even with the little issue with my compressor i am thoroughly impressed i have the 110v running chemlube 751 also...mine runs upto 52c than levels out regardless of how long it runs...i had a issue with the hose connection piece on yhe compressor so i contacted the seller who has been awesome for answering questions and making sure the replacement part is exactly what i need...i am getting 5 rebuilds andmore filter elements and the high pressure block and a few others for the price of shipping service is excellent even after purchasing i would highly suggest for the price and customer experience....as far as oil mine had residual as well and i was also informed they are tested before sale....i couldn't be more impressed with this little unit and the support even beimg from china i would buy another in a heartbeat
-
Thanks Mukilteo for trying the inverter generator. Might have to put a muffler on my 10KW genset instead. I think I'm pulling the trigger on this compressor. Thanks to all.

Well I hooked up the pc radiator I got in. I haven't had time to test it yet and probably won't for a couple days. I'll try and do these tests,
Baseline no radiator
Fan off
Fan on
Ice pack fan off
Ice pack fan on
Damp rag fan on
I think I'll run it 10 mins each test filling my guppy from 3500psi and recording the ending temp of each run.

I'm seriously looking into this compressor for my PCP fills.
Watching the videos for the Yong Heng one of the operators (Wingman 115) instructs that it's important to open the bleed before shutting off the unit because of potential preload damage to the unit.
I am planning to fill my Air Venturi 60 min SCBA tank which I don't think has a check valve. I was wondering if I opening the bleed without a check valve further damage or worse put me in a dangerous situation. Is there such a thing as an inline check valve that I can install? Is there any real damage to just shutting the compressor off, closing the scba valve and then opening the bleed valve?
What do yall think?
Thanks
-
Eric, that is how I fill my tank. I close the tank valve then open my bleeder screw.
-
Eric, that is how I fill my tank. I close the tank valve then open my bleeder screw.
I fill my SCBA's the same way but a check valve, if such a thing exists for HPA, sounds like a great idea especially when bleeding off moisture from the high side of the compressor.

Well my 69 dollar Chinese compressor did not show up yet and the 6th of July was the latest estimated shipping arrival date in eBay so don't hold any hope for it to show. I have already been refunded the 69 dollars into my PayPal account so all is good there but really wanted the compressor.
I just bought a Mutant so my funds for the compressors is drained but will eventually buy one of the 315-325 dollar compressors off eBay that are shipped from stateside sellers.

Somebody requested the amp draw so here's mine at 120 volts.
https://youtu.be/iUpEzixJdIE (https://youtu.be/iUpEzixJdIE)
I finally filled my 2.17 liter Acecare SCBA from Aliexpress and it took all of 23 1/2 minutes from completely empty to 4,500psi. I did do a brief bleed every few minutes. You don't need to bleed it hard core like I imagined you'd have to. Just barely crack the bleed screw open a bit and watch the water/mist shoot out a bit.
My YH never did get above 52 Celcius with ice in a 5 gallon bucket. My 1st stage pump got upwards of 160 degrees taken with an infrared tester and also with my Therm-App Hz thermal cam. The low pressure line as it enters into the second stage seems to be hottest at about 200 degrees, right at the fitting.
My SCBA bottle never got above 110 degrees fahrenheit and my high pressure filter never got above 100. I did this all in one shot, no breaks or rests. I have a fill whip on my bottle with a gauge and a bleed screw. When I got up to 4,500 psi I simply turned off the compressor, closed the valve on my tank and then slowly bleed the line on my fill whip valve and also at the same time opened my compressor bleed screw to allow the pressure to release slowly from the lines and high pressure Golden filter. Then after I unhooked everything I left the bleed lines open and turned the compressor back on to blow out any moisture in the heads.
Next time I fill won't be from empty so it'll take about ten minutes or less. I did remove the pc cooling fan that I had on that was fighting the flow of the YH motor housing fan as it's not needed. There's plenty of air running over the first stage cooling fins.
My flow indicator is a Godsend. I suggest everyone incorporate one into their system. Quick visual indicator was quite helpful as this was my first time really putting the compressor to its paces and I didn't need to have to worry about monitoring the flow by looking into the bucket.
Not sure what else to add except that I ran the compressor with no load for 10 mins, drained out the nasty gunk inside, complete with metallic shavings in it. Removed the cover and wiped everything down, reinstalled it and refilled with Chemlube 751. The little tampon filter that came with the YH was a bit moist after the run. I would NOT want to run this without my Golden high pressure filter. And regarding the hp filter, the inlet tampon was maybe, just MAYBE a bit damp. The output tampon was dry as a bone. I did not remove my sieve material to check as I'm sure it's barely even moist. I did end up putting in an inch layer of activated charcoal into the pvc tube inside the hp filter before running this as well.
Anyway, I'm quite please with this unit and wouldn't be afraid to try a bigger tank with it, though you'd have to be there to monitor it, which I don't mind doing at all.

I did record a video of my run but it went too long I guess for the app on my phone so it stopped recording in thermal vision. Drats. It was cool to watch the compressor's components start to warm up as well as the fill whip and small filter whilst everything else stayed much cooler.
I did begin to record my setup at first but forgot my ice so at least this video is better than nothing...in the vid the compressor had already been warmed up to operating temperature from my testing before the big fill.

Mike, I ordered everything through Amazon. The total was about $100 for the fans, radiator, and hose connectors. There are cheaper radiators but I went a little more expensive for the full copper vs aluminum.

The YH compressor came in late this evening. The packaging is very good. Took some pictures of the unpacking.
This 110vac YHC seems to be pretty heavy duty. The Lube-V oil came in on Saturday.
I want to check everything I can, to make sure there aren't any loose connections etc.
Any tips would appreciated.
Thanks,
Rich
-
I just ran mine. Didn't do any leak checks or anything. I did run it with no bottle hooked up for 10-15 mins with hydraulic oil and then drained it and removed the front cover and wiped out the residue. Refilled with fresh and called it good. Just be sure to always, always, always make sure there is water flowing to the head.
-
I did the same with mine. I just ran it for a few minutes not hooked to anything. Then did some short run time fills. After I had about 20 minutes on run time on it I changed out the first fill of oil to flush out any gunk left over from production. Its been running fine since then. I'm currently using the chemlube 751 in it.

Using my compressor today and the temperature gauge stop working. Don't know if a wire came off the temperature gauge or it's no good. Will update what I find when I take off the cover.
-
Label me "not surprised" as that wire is dinky on my Yong Heng and the whole compressor vibrates to high heaven.
-
Did the display go dark or did it just stop reading temp and still displays #'s?
I haven't pulled mine yet since its still working, but, it must be battery operated. If it no longer displays digit's, I'd check the batteries. The thermistor should have only 2 wires, should be simple to track down if its just a lose solder connection.
I think this is the same temp unit in my compressor...

-
I'm betting it's the battery came loose or died. Hope it's that simple.
-
Update was not the battery as the temperature gauge had a reading just was not rising as the compressor is running. After i removed the cover I saw the the wire with the probe on the end not attached to anything. Took a flashlight and was looking for the temperature probe holder and did not find it so, I do not know where the probe is supposed to go. I inpervised and drill a hole on one of the cooling fins the same diameter as the probe and stuck it in there. Temperature gauge is working again but I still would like to know where the probe attaches to.
-
Ken what compressor do you have?edit: looking back in this thread I see we have the same compressor. Should be in the same spot as my pictures...
On my yong heng,the probe sticks into the lower part of the cooling head. I'll add a pic in a bit...

Thanks for the info! I'm thinking that a 5 gallon bucket should do the job.
One thing that worries me a bit, is dropping that water pump in the bucket. If the case leaks, that might be a shock hazard..
I got busy this morning and didn't get to many of my chores today. Have not started any testing yet,
since I wanted to test the dehumidifier in the basement. Don't want to run the compressor in 75% RH..
The dehumidifier is working poorly, so I'll be working on that problem before testing the compressor.
When draining the break-in oil, did it look dirty or was it clean?
I'm asking, because I see a bit of clean-looking factory oil under the sight-glass.
Maybe the factory testing oil already cleaned it out pretty good? Or not?
After reading the tiny manual, about installing a gasket on the hose from the output port, which gasket should be used?
There's a unopened bag of them, what size/color did you guys use? Or should I just use Teflon tape?
Thanks,
Rich

Glad to help Ken, you've helped so many of us it's nice to pay you back so to speak 8)
My probe hasn't moved in a couple hours of run so far. If it does, I think some thermal grease might be the ticket to help hold it in place and may help give better readings as well.

That thermal grease sounds like a great idea. I checked my sensor and it sides right out.
The only thing holding it in place, is the pressure of the wire. It fits in the hole okay, but it's not tight at all.
I've got some thick heat sink grease that might help it stay in place. Better heat transfer means faster updates on the LCD.
I think you are right about being more accurate too.
The compressor vibration, bouncing the sensor around in there, can't be good for accuracy..

Thermal grease never heard of it?
-
Possibly thermal paste like on computer boards to heat sinks. Other than that I know of no thermal grease.
-
I just checked my Yong Heng temperature probe and found that it slides out very easily. I cleaned the probe and the hole that it slides in to and added a light coat of thermal paste and now it fits very snug. Thanks for the great idea.

Thermal grease, paste, heat sink compound, it's all basically the same thing just different terms... all though, not all compounds are created equally.

Could get a plug in GFCI. Keep in mind, the plastic case has NOTHING to do with the sealing on the wires/magnets. The wires/magnets are potted in epoxy. On the other hand, this is a product of china.......

There is a GFI under the kitchen sink. I could use that socket and the SS sink to test for voltage leakage.
If it can run a while without failure, I'll feel safer..
When look at this thing, I think of the old space heater in the tub 007 trick.. "Shocking. Positively shocking"..
-
Okay Bizill, I have two of those white plastic aspirins w/1mm hole inside a bag and there was also one inside the output port..
Just like you said! I guess when they tested these, they just left that one in, and they don't seem to fall out while at sea.. :)
Also got the the heat sink compound on the thermistor. Found my little oil funnel while I was looking for tools.
I'm going to be all set when I get the basement dried out (92%RH). It's been raining like crazy here..

Rich, be sure to break that compressor in with new oil for at least 10 mins with the water flowing through the head. Drain all that nastiness while it's warm. Actually, warm, cooled, doesn't matter as it'll flow out nicely. If I were to do it over again, I'd do 2 flush cycles to get all the &^^& out, though it's not necessary. I just like overkill.
I'll also have to check my temp probe to make sure it's snug as a bug in a rug. I do know that my temp gauge display is undersize in an oversized hole as it vibrates back 'n forth a lot. I'll probably address that as the optical illusion it creates to my eyes is funky. It makes it look like the entire cover is moving all about when it's just the gauge display.
I also have a male to male foster plug with one side having a check valve in it from Air Tanks Plus. It'll act sort of like a priority valve. All I care about is not having to build pressure on the compressor/high pressure filter side and then time it so I open the scba tank when it's at about the same pressure. This way I figure if my SCBA is at say, 3000 psi then I can open the scba valve and it'll hold the check valve shut and then when the compressure builds its way up to 3000 psi then the check valve will open on its own without me hovering over the gauges and scba valve. Also when I am finished and go to bleed the system down, I can have it so that there is little to no backflow through the high pressure filter. It wouldn't matter either way but sounds like one less step for me during filling and I lik that.

Have a minor problem with the gauge. Needle is bouncing around and when I bleed the system from filling sometimes the gauge will not return back to zero. Have to tap the gauge to make the needle go back to zero.the needle Reads 10 psi off from zero and I have to tap the gauge to get needle to zero. I'm going to have to get a new gauge that is liquid filled. I believe the liquid filled gauge will help with the vibration of the compressor while filling. The gauge still works but due to the vibration the gauge is not accurate any more. After all I have used the sh?)& out of this compressor since the first week of April😎 And it is still filling my guns and tanks to feed my addiction to these guns😳 I would advise to change out the gauge to a liquid filled gauge. The gauge will need to be the same diameter as the he one on the compressor due to the metal line the is very close to the gauge. So guys and gals, can you all find s gauge the would replace the one on this compressor.
-
Like the rest of the hose fittings, the gauge is M10x1.0 straight threads....
I didn't find a better quality gauge, I didn't look really hard either... I did order one of these as a spare and use my tank gauges for comparison.

EDIT:
Hummm, I just noticed. Your gauge is not glycerin filled? Mine is... Maybe they didn't use filled gauges in the early production models? Or, did yours maybe leak?
-
This is your video right? Can't tell if the gauge is filled, but, it does look exactly like my gauge from the few glimpses I got... it should have been glycerin filled from day one..

Yes my video. What I did notice on the side of the gauge is a black plug. Didn't really paid that much attention until now. Must have been filled with glycerin. Must have leaked out from the seller to me. Is yours liquid filled gauge?

Thanks for the link I'm going to say it was at one time glycerin filled and I didn't pay close attention and notice the black plug on the side of the gauge. That would explain the bounce of the needle while the compressor is running. Going to have to find a gauge in the u.s. For faster shipping. The link you listed shows shipping from China and approx august 14 arrival date. If I can not find a gauge on this side of the pond then I have no choice but to order it.
-
Yep, if it has the black plug it SHOULD have been filled. Yes, mine is glycerin filled.
You can get glycerin at many pharmacy's, if the gauge is still working, just bouncing during run, filling it with glycerin will dampen the bounce. All the glycerin is in there for is dampening the needle.
pop the plug out, use a syringe if you have one to fill the gauge with glycerin and replace the plug.
-
Good luck finding a gauge locally with M10x1.0 straight threads... I didn't use my serious google foo, a quick search produced ZERO results.
Might be easier to find an M10x1.0 to either 1/8 or 1/4 NPT bushing. This would really open up gauge possibilities, make sure the bushing is rated for 6000psi though.

Thanks hmm, didn't know pharmacy's carried glycerin? Maybe the gauge has a leak?

I need a gauge that is 1-3/4" diameter glycerin filled gauge. This one is 2". If I buy this one the gauge will need a extended tube to get pass the air line
-
an example..

Either a leak or maybe it was never filled to begin with... hard to say.
you'll not only have to raise the linked gauge, you need bushings to get from M10x1.0 straight thread to 1/4NPT...
-
Thanks John for the link. Never knew what was in the gauges and where to buy. I learned something today thanks😊. Going to buy and fill first to see if there is a leak in the gauge and see if the needle will return back to zero before I ordered another gauge
-
I'm going to remove the gauge from the compressor and refill the gauge. I'll let you know if the gauge is leaking or not
-
Not sure what chain pharmacy's are in MI. I would think one of them would have 100%, clear glycerin on the shelf.
I did have my gauge stick once. I did some high side filter work and wanted to leak check. Pressurized to 2K and shut off the compressor. I didn't find any leaks, so I released the pressure, gauge stayed at 2K....
I turned the compressor back on, let it build pressure until the needle moved. Opened the bleed, gauge dropped to zero, then I shut off the compressor. Gauge has been working fine ever since.
-
I was reading in one of the various brands of compressors the manufacturer did away with the glycerin as it was not needed. A forum poster decided to fill his anyway and ran into a few snags. It may have been the Carette compressor.
-
I had read they were drained before shipping if its shipped by air.
-
I had read they were drained before shipping if its shipped by air.
Hmm if that is the case, the seller didn't add a note saying that the gauge was drained
-
I remember reading that from one of the sellers on Aliexpress. I don't think it was stated from the seller I purchased from.
-
The 6000 psi check valve arrived today and I installed it between the black and gold filters after adding quick disconnects on both ends. I then proceeded to top off one of my SCBA tanks. The valve worked just as I had hoped. I was able to purge the compressor without having to shut off the SCBA valve. This makes filling the tanks just as easy as filling a gun directly.
-
Well I bought some glycerin today and filled the gauge. It help dampen the needle but I'm afraid now since the needle will not Zero it is not accurate enough. This one will get me by until the new gauge comes in
-
what do you guys know about this one ?
it says 220 60hz. & to use #46 hydraulic oil.
i will not be filling any tanks, just for topping off rifles.

Why do you want one for each end of the filter?
-
Ken,
Roberts check valve will trap the air in the high side filter, hose and air tank when water bleeds are being done.
It will also eliminate the need to close the tank valve when doing water bleeds.
Great idea.
-
Why do you want one for each end of the filter?
My goal was to hold pressure in the large filter after a refill, but after giving it some thought a check valve on the out put won't work, so I think that I will add a needle valve together with a bleeder on the output that will allow the filter to stay pressurized to save time for the next refill. I will add the check valve on the input side of the filter as you suggested. I found that it takes quite a few minutes to fill up the empty filter. Bob

You definitely need some way to depressurize the filter when you want to open it up to change the filter media.
BTW, I just eliminated the QD on the output side of the valve (input side of the filter) and screwed the valve directly into the filter.
-
Here's a couple of pics of the check valve setup. The check valve is the stainless steel piece that is in between the black filter and the gold filter. The input side of the valve is depressurized with the bleed valve on the compressor and the output side is depressurized with the bleed valve on the fill station. This setup works for filling tanks but is not needed for filling guns because the gun already has a check valve built-in.

Ok thanks for the picture and explanation makes more sense now😎

where can you get the gold and black filters ?

The black filter comes with the Yong Heng compressor.

Before I found about the large GOLD filter I purchased the Diablo filter about a month ago.
http://www.airgunsofarizona.com/pcp-accessories/diablo-dry-air-system/ (http://www.airgunsofarizona.com/pcp-accessories/diablo-dry-air-system/)
I could of saved $100.00 if I did more research at the time. It works great but a little costly. Bob
-
Bob I have the diabolo air dry system as well. I found the gold filter on Ali express after the fact for cheaper. The only difference is the color. Go figure
-
I had seen the gold filter when I first ordered the Tuxing compressor I'm using now. I knew about the Diablo system and that is what I ordered. I hope the gold filter works well for everyone but, with the recent bolt handle breakage issues noted with the PR900 rifles, I'm glad I have a product sold by an American vendor for this specific high pressure application. The two could very well be made in the same factory and using the same materials and ultimately they may be exactly the same but 3000 psi (4500 for some guns?) contained inside a metal cylinder is always a concern.
-
I didn't think the filters were the same? I have one of the gold filters. Mine has two different cotton filters inside. I thought the Diablo had molecular sieve material?
-
Kurt,
Most,if not all of us, have modified our Gold filters to use sieve and carbon. I do use about an inch of the tampon at each end of my modified gold filter.
The tampons MIGHT be enough, the sieve/carbon will do a better job of getting DRY air in your tanks and or guns.
-
When I said "the same", I meant in terms of the tube material itself and not the drying/filtering material inside. I hope both the Diablo and the gold filter are made of high quality material for the tube body and end caps. Recent breakage of bolt arms on some PR900's just made me more conscious of the issue of material strength, especially with contained high pressure near me.

https://www.gatewaytoairguns.org/GTA/index.php?topic=128442.0 (https://www.gatewaytoairguns.org/GTA/index.php?topic=128442.0)
Except for finding out that there is a global ISO certification I have not been able to find out anything more.
Thanks,

-
i have read where the gold filter works best when installed vertical with the input at the bottom and output on top.....is this correct ??
thank you
-
John,
I think this is true for any filter... let gravity help as much as it can ;)
I have my gold filter mounted vertical, I use the "black" yong heng filter as a pre filter, also vertical.
-
is there a supplier for the pre-filter that has quick-connects for hooking the input hose up from the pump and output directly to the gold filter ??
sorry for all the questions, i appreciate your information.
i purchased the gold filter this morning.
thank you,
-
How I have mine set up.
Waiting on the check valve for the input side.
Also am checking out bleed valves for the output side so I can release the pressure when filling the p-rod.
-
I believe the gold filter and the diabolo filter have the same sieve material inside just a different color and cheaper
-
so the "black" diabolo is just a smaller version of the "gold" type thats previously pictured ?

Ouch! Paid $ 179 r&l. Go with the gold filter for less
-
Does anyone have the Diablo and the gold chinese filter? Are there any testing certifications on either?
Thanks,
Taso
-
The "black" filter comes with the yong heng compressor. It uses a tampon, I've lined mine with UHMW and added sieve thats thrown out after each use. I do use a small piece of the tampon to "plug" the outlet of the filter... you'll know what I mean if you have the same black filter.
I decided to use the hose end threaded directly into the black filter, then the black filter threads directly into the intake of the gold filter. On the discharge of the gold filter is a foster, I hook my micro bore hose to this and then my tank.
-
is there any need for the "black" pre-filter ?
-
None on the diabolo
-
I use the black filter inline that came with the yong heng compressor along with the red diabolo filter for added protection
-
Gotcha...thank you !!!
-
All in the spelling. Diablo is the Devil red high pressure filter. Diabolo is the name JSB gives their pellets.
The black high pressure filter given with the Yong Heng uses a tampon-like material. Be careful here as newbies might think they can jack their wife's Kotex and use it. They are sold to fit precisely in the black filter as well as some are sized for the big gold high pressure filter. They are pretty much sold by the same sellers that sell the compressors and high pressure filters. It's suggested you buy some spares while you buy either to save on shipping.
I like the little black high pressure filter to absorb the oil blow-by that gets past the compressor and into the high pressure air stream, before it hits my gold high pressure filter. In my gold high pressure filter I have a "tampon" first, then an inch long layer of activated charcoal, then a small circle of my fish filter to seperate the charcoal from the molecular sieve material and then a small "tampon" at the end and out to the airgun or tank it all goes.
That black filter does get good and moist as well as absorbs some oil. I think I ought to buy more spares for this sized "tampon" and toss them out after each use.
-
Does anyone have a picture on whats on the inside of the Diablo?
-
My diabolo came with blue seive inside it
-
I ordered my Diablo filter from AoA and it is BLACK-I think red must be an optional color. I don't see any specifications marked on the body and certainly hope that the Diablo (whatever color) and the gold Chinese filter are both made from adequately strong material with an acceptable safety margin. The cost difference wasn't enough for me to consider the Chinese alternative in light of the above question but I'm sure both will function just fine.
-
Bob (rsterne) could probably give us a guesstimated yield strength of the filter if someone could come up with dimensions. I'm guessing the material is either 6061 or 7075 but who knows what temper. I'd image it's T-6.
-
Nobody can guestimate without knowing the material. Knowing the material and dimensions you dont need to guess it's just math.
Most likely its some form of free machining automatic grade alu like 6082. But cant say for sure.
If in doubt do as I did, hydro the stuff.
Marko
-
You definitely need some way to depressurize the filter when you want to open it up to change the filter media.
Wouldn't the filter depressurize once you open the bleed valve on the tank?
-
I ordered my yong heng compressor today and from what I've read so far its main problem is heat and lack of filtering?
There also seems to be nothing controlling the pressure where it shuts down, so you'd have to be monitoring the gauge and switch it off at the desired pressure? Diablo dry air system seems to be made from 6061-T6, thats 275 N/mm2 yield strength.
I think the word diabolo is most of the time used to describe the hourglass shapedness of something, but the word originates from Greek and then someone christened the yo-yo game as diabolo and thats how it got connected to hourglass shape and pellets.

A reliable auto-shut off is one of my big concerns because I don't want to damage anything. I am in the process of adding a shutoff switch when I find time. I did receive the switch a couple of weeks ago from China but I have to machine an adaptor 1/2" NPT to 10mmx1 in order to get it functional. Bob

So basically you have to have 24 volt dc power supply from which you power that controller/gauge an then you just wire the controller output to 24v dc contactor/relay to turn off the motor?
-
You definitely need some way to depressurize the filter when you want to open it up to change the filter media.
Wouldn't the filter depressurize once you open the bleed valve on the tank?
Not if you have check valves on both ends which was the scenario that I was replying to.

The same switch on ebay is also offered in a 220v version which can be used for either 110v or 220v: http://www.ebay.com/itm/162213021706?ssPageName=STRK:MEWAX:IT (http://www.ebay.com/itm/162213021706?ssPageName=STRK:MEWAX:IT)

That's not the same as it is only rated 0-1 Mpa where the other is rated 0-40Mpa.

Albert, Yes you are correct. I will be using two 12 volt @ 1 Amp wall warts in series to power the gauge and 12 volts to power a PC fan to assist in cooling. I will also be using a 12 volt input SSR (Solid State Relay) to power the 120 volt compressor. I have everything but time to complete this mod. Bob

I was going to go with a unit with auto-shutoff but decided I didn't want to trust them to actually shutoff. Personally, I'd rather monitor the pressure myself and turn the compressor off. I know there are burst disks installed but I don't know how much I trust them either. I haven't heard of any of these compressors failing to shut off the machine but I will be sticking to my wits when it comes to reaching target pressure. That was my deciding factor in choosing the 110 volt sans auto shutoff vs the Yong Heng 220 volt with it. That, and portability of 110 volts, of course.
When I was breaking in my Yong Heng the other week my gal decided to microwave something up and it tripped my breaker. Well, now I know which outlets are wired to the same circuit. Ok, microwave is off-limits whilst dad gets to compressing air. It frightened me as the YH just stopped working out of the blue and in that instant my mind was already going through the paces of how to deal with the seller and shipment logistics back to China and a split second later I looked up and saw my gal at the microwave wondering what had happened as well.
-
Bizill that probably would have given me scary moment also until I realized what had happened.
-
It truly sucked in that moment as I had been anticipating this little compressor oddly enough more than I had anticipated any of my airguns delivery. My stomach almost turned in that moment and in rushed all those times people utter the phrase, "you get what you pay for." Luckily for me, or most of us, these compressors seem to, as stupid 0bama would say (the same exact to multiple leaders) "punch above their weight."

I was able to check out my new YongHeng compressor today.
I ran it a little while under no load and watched how fast the heat was climbing.
Used a 47Ci 3000PSI paintball tank for my first test. From zero pressure, bled the air and stopped (4 times)
at 1000, 1500, 2000 and stopped filling at 2800 PSI.
Did not get any water spray when bleeding. The relative Humidity was 45% in the basement.
I checked the (cotton) filter and it felt dry. There was a thin 2mm wide oil stain on the filter.
After each run, I checked temperatures with my heat sensor pistol. The top of the head stayed cool.
While the bottom gets really warm.. 40 to 50C comes quickly. After turning off, the cast iron (lower head)
stays hot for about 5 minutes (room temp was about 21C), the aluminum top part is at 20C within a minute.
My PRod was down to 1,000 PSI.. I realized that my muzzle extension had to come off the rifle,
because of that large black filter wouldn't allow the quick-connector to line up and snap on..
My next surprise was the short amount of time it took to go from 1000 to 3000PSI.
After I started it, I stepped over to look at the KillaWatt meter (I think it was around 15 amps)!
When I turned around, the YH pressure gauge was already nearing 3000.
I quickly opened the bleed and hit the power off. The gauge on the PRod was just over 3000PSI.
It seemed like this top-off only took about 15 seconds.
My advice to pistol shooters, stay on very close and be ready to shut it down..
For cooling, I was using 4 or 5 gallons of water (without Water-Wetter) in our Ice Chest. (insulated).
When I was done, the water had gone from 20 to 21C.
I believe topping off the PRod can be cooled with a 1 gallon water bucket, 5 gallons isn't needed.
Not sure about topping off my rifle (.22cal AT44-10 QE), but my guess is, going from 2000 to 3000
will be so fast, 1 gallon is not going to bring the water up more than 25C.. (20 is tap water temp here).
Note on Sound:
While filling the paintball bottle, I noticed a few changes in sound of the compressor.
The steady hum note, would shift a little and sound a little difference. (Pressure gauge not effected).
Once it seemed like the unit hiccuped.. That might have been the grid.
This afternoon I was testing during high usage lower voltage hours..
Note on gauge: It seems like mine doesn't have any oil either..
I have an oil filled gauge(2000psi), and it's got bubbles.. This YH pressure gauge is bubble free..
It works fine and doesn't vibrate into invisibility like the gauge on my tire compressor..
Edit: Last night, I noticed the gauge glows in the dark! So if you pop a breaker, wind up in a pitch dark room,
you can still locate the bleed knob, a few inches down from the glowing pressure dial.. (don't touch the hot parts)!
I stuck a flashlight on it, and it glowed really bright! :)

Rich

Good review Rich....

Good to hear some feedback on these.
How much are you guys having to invest in filtering these units? I know filter units can get pricey...
-
I've got just over $100 in my high side filter. I can replace the media a dozen times, maybe more, with the amounts I bought...
$70 shipped for the filter housing(aliexpress)
$22 shipped for 3lb of 13x sieve(ebay)
$8 for activated carbon at Wal-Mart
$2 for a 2ft section of 1" SCH40 PVC at Lowes(any hard ware store will have this)
Couple O rings I already had in an O ring kit...

Does anyone have this one?
I have sent the seller questions but have not yet replied.
In the description it states 120/220 50hz
Do any of you folks use this type for 120/240 60hz ?
As long as its compatible with 60hz, i can use it with either 120 or 240 volts.
Thanks for your information.

Water Pump Problem:
Yesterday, I decided to remove the hose from the water pump. I had just started to remove the hose, when the plastic nipple just came right out.
It came out with just a slight tug. After inspecting everything closely, it looked like it was a press-fit. Not glued in place..
I decided to try some superglue. It's not coming out now..
So, if your YH compressor starts overheating badly, check the pump nipple, it may have popped out..
Cheers,
Rich

Filter question:
I'm thinking about using a pre-filter inline with the air-input to my compressor.
A YouTube video, Google "Silica Gel under high vacuum.avi"
Seems to be saying that Silica Gel desiccant can be vacuumed dry for re-use..
I own a HVAC 50 micron vacuum pump, that might be useful to refurbish Silica Gel..
Would a Silica Gel filter be effective (to remove water) on the air-input to my Ebay compressor?
Thanks,
Rich
-
Gendoc contact the seller to make sure you get a 120 volt
-
Richard,
I had thought of a drying intake air as well. I think, With as fast as these little pumps move air, to have enough drying volume/dwell time to do any good, you'll severely limit intake air and actually hinder air compression.
With this compressor, I think drying after the air is compressed is more important and useful than trying to dry air going in.
-
After giving this some thought I think putting a filter on the air intake may cause problems. The compressor was designed to work at atmospheric pressure. Anything you put on the intake will create a restriction and reduce atmospheric pressure and create more suction than normal. This small increase in suction may draw oil into the compression chamber.
What you may be able to do is use a regular 100 psi home compressor. You could feed the desiccant filter 100 psi air and then regulate it down to zero or .5 psi to feed the input of the hpa compressor. A gauge reading of 14.7 psi means 14.7 psi over normal atmospheric pressure. You can see this if you use the same gauge with nothing connected to it. It should read zero.
So yes, I think it can be done. Would there be much benefit? I don't think so. You may slightly reduce the amount of liquid water collected at the 1st and 2nd stage compressor bleeds. But since you're regularly opening the bleeds there would be no significant benefit. The remaining moisture going to your tank or gun will be in gas form. That is why you need the molecular sieve on the output side of the hpa compressor. Also the higher pressure the molecular sieve is under the more effective it is.
Thanks,
Taso

Because there is not a 120 50hz voltage over there.

Be aware that unless the super glue you used clearly states not water soluble it will be dissolved by the water its put into and allow the nipple to come loose. Medical super glues are not water soluble and I believe you can find non water soluble super glue at auto supply stores as well. Just thought I would let you know so you can keep an eye on it to see if it comes loose.

Wow, I didn't know that about super glue. I used it at work, on items (experimental antenna parts) that were used in the rain,
and never had any problems. I suspect the 'government' super glue wasn't the same stuff we get at the dollar store.. :)
Thanks for the info. I checked the package, and it's not recommended for water immersion.
I will let the pump soak for a while before using it this afternoon.
I have two screw-on cylinders for my FT rifle, that need to be topped off..
I noticed the water pump has a little lever, that swings to - & + , if in the - position, there is no flow..
Thanks,

Its been my experience that it has to be immersed for several hours to dissolve the super glue so being subject to rain likely is not enough time or immersion in water to really dissolve the glue. I have some Mil Spec super glue that that I believe is non water soluble but have never tested it to be sure.
In my past as a GM technician when the Cadillac Alante first came out it had some bad weather strips around the convertible roof to windshield that would leak in heavy rain. Cadillac issued a service bulletin that had some small pieces of weather strip that had to be glued in place over the existing weather strips and the kit included some medical grade super glue that stated not water soluble. That's when I found out that the super glue from every day stores was not going to hold up in extended contact or immersed in water. It also had a warning to not allow contact with skin since it would have to be cut loose to remove from the skin whereas with normal super glue you can soak in water to dissolve it from your skin.

I should have read your post Mike, before cleaning up in the basement. (It's back in the water)
The two 300 Bar cylinders were both down to about 100 Bar.
There was an air-leakage problem at the gasket on the black filter, where the QD screws into the black aluminum filter cap.
I changed the gasket and it still leaked. Used Teflon tape and got one cylinder up to 250 Bar. It was failing at the end.
I put the old gasket back, removed all traces of Teflon, and decided to drop a small O-ring
into the bottom of the hole, and screw the QD assembly in to compress the O-ring.
My last attempt was successful. No gauge on that tube, but the compressor gauge showed about 270 Bar.
I didn't want to push these up to a full 300 bar, until I can schedule some FT practice. Maybe in the Fall..
Can somebody please tell me, should there be an O-ring in the hole, under the QD assembly?
Thanks,
Rich
PS:
The second tube filled up pretty fast. Temp peaked at 45C. Both tubes were filled in to short cycles.
The small water bucket with about 1.4 gallons (added a little water-wetter) went from 21.5C to 25.2C (70.7f to 77.36f).
So, using a small 1-gallon bucket should be fine for topping off my rifles..
Dominator LG400 Cylinder Length: 460 mm, size 267 ccm
So topping off the Hatsan AT44-10 (medium length?) should be doable in one or two very short cycles (fill-cool-fill)..
If I only shoot it down to 2000 PSI, I think filling it to 3000 in one cycle will peak the heat up around 50C.. I hope..

I'm fairly certain the insert atop the water pump is supposed to come out with a gentle tug. You don't want to constantly pull a tube off a nipple so they make it so that you can simply tug the tube off the pump for any given reason you'd want to. Would you want to keep pulling the tubes off the nipples on the compressor head often? Not a good idea, off, on, off, on. I like the fact that I can pull the tube with insert off. So long as it's not too loose so as to fall off during operation. It's pretty snug and I have no fear it'll come unplugged on its own on mine. I would not have tried to glue it in place, good sir.
-
What is the thread size on yongheng fill hose, M10x1? I was thinking about making all the necessary fill probes ready before the compressor arrives.

Mine was just a little too loose for comfort. Any slight tug on the hose while filling (or the water pressure inside it) might cause the 'insert' to pop out.
Which would cause instant over-heating. If not noticed until 99C, might be problematic..
I never intended to ever be disconnecting the water hoses. But, I was checking out the idea of a safety cover for the water container, with two 1/2" holes in it for the hoses. So, I was trying to remove the pump hose.
~~~
Before I got lazy and used the Super-Glue (which is still holding), I had the idea hanging a small steel ring on the output hose, using a cable tie.
Then use a rubber-band around the pump-body connected to the steel ring, as a hose keeper..
That might make it much harder for the hose to accidentally pop off the pump..
Cheers,
Rich

What is the thread size on yongheng fill hose, M10x1? I was thinking about making all the necessary fill probes ready before the compressor arrives.
I found the fill hose-filter on Ebay. eBay item number: 322580855430
The text says:
Packing include:
1. High pressure hose - 1 piece. Could be used up to 5000 Psi or 40 Mpa. Connection: inlet/outlet - M10 x 1mm male connection. One side to the Oil-water filter device another side to the pump or tank. The length of the hose is 19.68inch / 50cm
2. Oil-water filter device - 1 piece. The device can hold one filter which can stop a moisture or an oil.
3. Filters - 5 pieces
That hose is a bit short.. So far, mine is working okay.. Still not leaking yet. That O-ring is holding.
Edit:
I was just looking at that Ebay 322580855430 kit and it might be pretty easy to double the length of the Whip
and add one more Black Filter in the middle.. Doubling the filtering.. :)
-
Yeah Rich, yours was probably a bit looser than mine so I would have addressed it as well. With mine it's snug enough to pull on the hose and it holds tight enough to lift the pump after it pops the suction cup feet from the bottom of the bucket. Yours sounds like it would have pulled itself right out.

there is so much talk about these filters not worth anything....you think its because
regular maintenance has been neglected ??
thank you for the link ;)

Yes thanks for the link

I received some sad news in a PM this morning.. Mr. George at Sea Divers is closing up shop in August. Mr. George is in his late 80's and has been diving and teaching all his life. He has been my go to guy for tank inspections and fillings. He's also been a ray of light to spend time with. I looked forward to my 80 mile round trips to see Mr. George when I could or needed to. This is not only sad news because I will miss those hours when he opened the shop at odd hours for me whenever I called and we sat and talked about his experiences, it also leaves me an added incentive to secure a source for HPA.

Ken (kzz1kaw) listed a compressor deal thats hard to beat about a week ago.
thats the one i ordered.
look back a few threads, maybe pages ???
-
John,
I use the black filter as a pre filter for my large Gold filter filled with sieve and charcoal. the black filter catches a LOT of moisture that would have went straight into my larger filter... Even with frequent water bleeds. I think it helps and certainly can't hurt using it!
Now, on its own, the black filter is nearly worthless. if its the only thing between your compressor and air tank or gun, you are pumping water into what ever is being filled. Yes, its better than nothing at all but not by enough to make a difference....

Thanks John... that's the one in my crosshairs.
As a matter of fact, with Betty Lou's blessing, We arrainged the spare room for a makeshift work space and filling station. The compressor will be in a controlled climate area located at one end of our home near her computer/garden view room. Rambo the Rescue Dog didn't even mind the fact that Mom and Dad will be taking space in his sleeping quarters.
-
Question for those that have 2 or more hours of run on the yong heng.
When doing water bleeds, do you see any oil in the water?
I'm approaching 4 hours of run. During my last two 30min run sessions, I noticed the water was slightly discolored. I put a paper towel below the water bleed port, it use to be wet but clean. Now, it's obvious some oil is passing thru. It's a tiny amount, I'm not seeing a drop in oil level yet and have no oil leaks. Looking at the oil thru the sight glass it's still clear and clean. I have about 1.5 hours of run since I changed oil.
Compressor is running fine knock on wood...
-
John my water is slightly discolored as well. I just changed it couple weeks ago and has a slight discolor to it. I don't see any evidence of water in the oil or that my oil level has dropped that I know of but that is me looking at the sight glass
-
Thanks Ken,
I think you've got more run time than any of the rest of us.
I'm seeing the same as far as oil, I'm not concerned at this point. More curious if others were seeing the same.
Thanks again.
-
Most anything coming from China is "greased" up to avoid "corruption" during the "cruise" to the States. Could be what you're seeing is whatever type domestic animal fat they used to slather on and in it.
-
I'm going to have to position some paper towels below the two bleed ports.
Since I'm only using the black filter, I'm bleeding often and 'feeling' for water, unsuccessfully.
Tomorrow, I'll see what the paper towel says.
Thanks to you guys, I'm slowly learning the ropes, again.
In 1963, I was trained to fill up our Scott-pack bottles at the NOB FD..
Pretty soon, the UDT guys from the EOD shop were bugging me to fill their SCUBA tanks..
I forgot just about everything, but put the bottles in a big bucket of water..
One thing I clearly remember about working in the FD shop, is to never put 2 over-pressure disks in the CO2 pump..
(And that 15 pound CO2 bottles have a seam that splits when over-filled).. Took out most of the shop windows.. :(
Cheers,
Rich
PS: The compressor that I paid $310 for, (free ship from LA by solar.jean) is now $351.99
That is quite a jump and now solar.jean is shipping from ShangHai, China. Demand increasing?
-
I'm currently using a Tuxing 220v with transformer and function has been fine but I just got shipping confirmation on the Yong Heng that Ken had listed earlier. Couldn't pass it up for under $300 shipped. Some oil sheen is noticeable on the cooling water surface with my current set up but it could be just cutting lube from the cooling port drilling and threading as it is very light.
-
My YH compressor arrived just half an hour ago. Haven't turned it on yet, just quickly checked that nothing is visibly broken, put some thermal goo on the temp probe and filled the gauge.
Instruction manual is in finest Jinglish of course and only helpful piece of information was that the lower pipe is water inlet. The part where the manual tells you to "screw up the screws" was entertaining as well. Only non technical persons are not allowed to arbitrarily disassemble, modify or repair this thing, who might they be? And remember folks "keep this instruction well during the trial period", I can only guess when the trial is over.
-
I'm seeing oil in the bleeding of the 1st stage pump bleed valve. The moisture has microscopic bubbes in it and it sticks to the side of the oil tank instead of "misting" out as does the 2nd stage pump side bleeder. Makes sense that some oil is getting past whatever rings they use in the low pressure pump head. Hence I use activated charcoal in my Gold hp filter. And you can see a bit of yellow stain on my black pre-filter tampon material on my Yong Heng. No cause for alarm on my part as this to me is to be expected.
-
Just tested my YH compressor and took notes. I test filled my AT44 180cc cylinder four times and here's how it went:
0-50 bar 20 sec. clt 29,5 c
0-100 bar 37 sec. clt 37,5 c
0-150 bar 59 sec. clt 41,0 c
0-200 bar 79 sec. clt 45,2 c
100-200 bar refill 42 sec. clt 45,0 c
Values above are average values of 4 fills, temps are from compressor gauge, I let the compressor cool to 21,0 c before each fill. I used 5 liters of tap water and during four fills its temperature went from 18,5 c to 27 c. Water temperature was measured with calibrated meter and when compressor temp said 21c, the actual value was 18,5 c. Amount of water collected from 1st stage bleed was 3 small drops.
-
This is my setup.

Sorry... With all the sidebar I didn't get through the whole thread. It's a little hard to tell from the photo but you ARE pumping the water into the lower fitting and allowing it to discharge from the top fitting right? It looks the other way around but in the photo it's hard to be sure.
-
Yes, I'm pumping water into the bottom fitting. I now have the filter mounted vertically as recommended by another forum member.
-
Agreed. In your picture it looks like the pump in your tub is toward the rear judging by where the cord enters, but then isn't that the pump visible near the front of the tub with the tube exiting straight up through the top and then plumbed to the top fitting? Or is the picture deceiving?
-
Picture is deceiving. The little suction cups on the bottom of the pump didn't hold and the pump had moved.
-
Richard,
I had thought of a drying intake air as well. I think, With as fast as these little pumps move air, to have enough drying volume/dwell time to do any good, you'll severely limit intake air and actually hinder air compression.
With this compressor, I think drying after the air is compressed is more important and useful than trying to dry air going in.
Has anyone tried sucking air through a Deep Freezer at -15 degrees? A Pvc pipe with ball valve put through the bottom side of the Freezer for output to pump and one at the top with a ball valve to let air in, When done just close the ball valves. I don't think there's any Humidity or air moisture in a frozen air at -15 ??? That's why they frost up, Probably would have to defrost every few months, But that would be easy, unplug and open the door. Just a thought?? As I don't have a pump YET but soon I hope. Jaa
-
Jay,
I first thought of running a copper coil through a refrigerator and searched online if anyone had tried it. the consensus was that the small dorm room size refrigerators do not recover fast enough to the temperature increase. If the flow through the copper coil was slow enough it could possibly work.
If you are going to use a freezer I think the copper coil would get plugged with ice after a while. Most likely faster with increased airflow. Then you'll still have the temperature recovery issue.
The cheapest solution I have found, initial purchase and running cost, would be a membrane drier. If you watch ebay you can find the low flow ones for under $100. Search for "smc idg"
Thanks,
Taso

Might get one if they get down around $150 to take on the road. They don't get too hot if your just filling guns or topping off a small guppy. May be a good tool for a Fun Shoot or a weekend camping trip.
-
yep, i bought the same one from ebay seller topsee for 285 shipped about 2 weeks ago
should be landing end of next week.... ;D
-
I'll buy a spare are $225 or so. I paid $324 shipped just over a month ago.
-
I thought I had done well on mine 312.00 shipped. I am always too early or too late.
-
Hmm might have to get another as a backup to the backup spare parts just in case😳
-
Oh and the one a bought back in April still chugging along😎👍🏾
-
When will the madness stop new airguns on the market prices will have to drop sooner or later compressors prices coming down. Going over to the dark side made me buy more guns😳
-
Taso, I was talking about using the whole volume of the freezer. Just a poly hose from ball valve fitting at the bottom of freezer to the pump intake, No coil's that would plug or ice up as you said, And an air intake ball valve fitting on top of freezer, Both would be opened when pumping, and closed when done, The only reason I was asking is, I retired from an aerospace metal finishing company, We used A Lot of air in that plant, Due to the sheer volume of air 2 Big Industrial compressors They run all compressed air thru 2 Big Chillers to dry the air and it self purges out the water, Lots of it, We never had a moisture problem as long as the chillers did their job. Right now I see a Big Difference here in Michigan pumping up 13 cu tanks Outdoors because of humidity at any temperature Vs pumping in Air conditioning at 72 degrees, I do my bleed off's with my hand pump after every set of 60 - 70 strokes, Outdoors pumping I get a fine mist and indoors with AC I get None that I can detect? But I'm sure there's is some. I'm not Saying we should all run out and buy a Freezer ;) But lots of us Already have them, Mine used to be stuffed full But with only one son that has yet to leave the nest ::) It's only half full most of the time now. Cold air is also denser than warm, And the incoming cold air may also help keep the head temps down a bit as well. So when I do get a compressor I'm going to give it a test, As I don't really have anything to lose? I figure it's only 2 holes I can always fill them with some spray foam, If it doesn't work out. Now I need to buy a few more guns or convert some over to HPA. Cheers Jaa
-
Jay,
Sorry, my mind was stuck on a pressurized intake like on my Shoebox.
Your idea should work on a Yong Heng or similar compressor.

Plus you can make an offer, I'm sure they would take $250. I think they will get to around $200, whether or not I can hold out that long is another story.

Made an offer for $225, don't think they'll take yet, we'll see.

Yep! Just tell them President Trump is going to halt ALL Exports from China, Due to their Lack of Action in stopping the China Supply Chain to N- Korea, That will get them wetting their little pants!!!

Dangit Jay,
I should have talked to you before making the offer, I left the notes section blank :-[ ;D
-
That is one heck of a deal😳

Maybe I'll offer $225.00 too.
Flood them with $225.00 offers.
Worth having as a backup.

Not a bad idea!
My thought as well. My compressor seems to be holding up fine. However, it's made me not really ever want to use my hand pumps or drive to get my tanks filled again...
Having a backup would be nice.
-
Watching with great interest.
I did not make it ALL the way through this thread, but I did read the first 5 or 6 pages, and then the last 5 or 6 pages.
If you don't mind, would you guys be so kind as to save me from pages and pages of reading though all the sidebar stuff, and answer some questions for me ?
From what I can tell, it seems you guys that have these compressors, are pretty happy with them ?
Has ANYONE had a serious mechanical failure with one yet ?
Has ANYONE had to do a rebuild/reseal yet ?
I see that several of you have also added the Gold Colored filter from AliExpress,... and then MODIFIED the filters to perform better.
Is this proven to be working better for those of you who have done it ?
There was also some chatter about a Black filter on LOW pressure side. is this also proving advantageous ?
What other details of pertinent or critical info do I need to know ?
Has anyone looked into feeding the input side with shop air pressure ? (100-125 psi) or is it even necessary ?
What is the total cost for those of you with the Compressor, Filters, Modifications, etc. ?
Has anyone hooked up a kill-a-watt meter to see what it costs to run one of these on the 110v ?
If everything is positive on these little compressors, I may have to put a few AG's, a Hill pump, and maybe even one of my (3) 60 min tanks, on the chopping block classifieds to fund one of these compressors ! ! ! ;) ;D
Thanks for any replies to my questions.

I know I am. Not really seen any complainants for the yong heng

Not for the yong heng. The only person I know of that had, maybe still has issues was a tuxing compressor. Same motor, drive box from what I can see, completely different heads.

Not that I know of.

YES! I wouldn't run my compressor without it
There was also some chatter about a Black filter on LOW pressure side. is this also proving advantageous ?
There is a particulate intake filter, is this what you're talking about?
What other details of pertinent or critical info do I need to know ?
Get the gold filter and set it up the same way as in the Chinese filter hack thread. Use good quality oil in the compressor. Make sure you keep an eye on temps. Shoot more, work less for it ;)

NO. I don't think this would work or be helpful.

Off the top of my head,about $450

I have,only to check amp draw though. Mine averages 11.5a. About 12.5-13 for a split second during start up.

John, Thank You so much for the quick and comprehensive reply.
On the Kill-A-Watt question, I'd like to figure out what the electricity cost is running this compressor .
Basically, I'm wanting to figure the cost of the compressor (with filters/mods/extras),...
and the electric operating cost,...
... and then compare that to what I currently pay to have my tanks filled.
So if anyone would care to do such a test, (I think it would be interesting to know),
What is the electricity cost, to fill lets say, a 60 minute/88 Cu. Ft. tank, from 2000psi to 4500psi ?
(I realize there will be SOME variation due to electrical rates and tiers etc.),
so I guess it should be calculated at a simple "average" rate (?)
-
Ron.... don't forget your lost shooting time for taking the tanks to be filled... lol
-
Ron I have not noticed a significant increase on my electric bill and I use this compressor almost daily to fill the air cylinder on the gun. If my electric bill was high I sure would notice it. Since owning this compressor since April, I had not have anything major go wrong the the compressor. I had minor issues such as the temp probe coming out of the head and replaced the gauge not returning back to zero. I would not hesitate to buy another as in my opinion the prices are starting to come down. I have a backup compressor an omega super charger that now sits in the corner of my workshop. I use it if I am filling scuba tanks from empty with this compressor is good for. Other than that , I use this compressor as it is compact doesn't weight as much as the omega and portable. I can top off scuba tanks guppy tanks and of course the airgun cylinder.
At the time I bought the omega, this compressor was not on the market. Paid $1900 for the omega 😳 That hurts. I could have saved $1500 by buying this and I would have bought it too late now. For me I would buy again😎
-
Oh forgot to mention, the other day had a brain fart. Going inside to have lunch so I unplug the water pump while I take my lunch. After lunch I was filling a hatsan air cylinder that I was setting the regulator. I turn on the compressor. I have a flow indicator inline on the pump hose that spins to let me now that the pump is circulating the water. I forget to plug in the water pump and I didn't pay attention to the temp gauge. Compressor is filling the cylinder to 200 bar. I'm plinking while the cylinder is filling. I smell something was burning. I look over at the compressor and realize I forgot to plug in the water pump. My cylinder did fill to 200bar. I look at the temperature gauge reading 100c😳 I plugged in the water pump and the lines blew right off in the compressor😳 I reconnect the hoses and this time the lines stay on. I felt the water and it was very hot so I replaced the water with fresh cool water. I watch the temp go down down to around 20c. I thought for sure I burn up the compressor. Thinking I did I was ready to buy another. the compressor cooled down, I turn on the compressor and water pump and filled the gun I was shooting to 200bar no problem 😳 I'm still using the compressor. This is one tough compressor 😳
-
Ron,
My compressor draws around 1300-1400W. Use this figure, your electric cost and one of the many online calculators to figure cost per hour. I'd fill my tank back up from 3000psi, I think this would take 45min or so for a 60min SCBA. From 3k,my 30min SCBA is full in about 20 min.
I drive for free, company car, can use it all I want. I don't pay a penny for fuel or maintenance. Still, I'd rather pay extra for the convenience of having a compressor in my gun room rather than have to drive for free to get tanks filled.... The cost of fills is not much either...I could have bought a lot of fills for the same $450 ;)
-
Convenience is huge... 2 hour round trip to my fill source plus time spent there.
-
For you guys/ gals that have the yong heng compressor, is there a way to hookup the water pump when you turn on the compressor? Just wish that the water pump was inline with the on off switch so I will not forget to plug in the water pump?
-

Thanks for posting this story. When running these compressors, constantly watching them is key. Let this be a reminder for all of us.
-
Might even put a cover over the start switch that you have to flip open. Paint it bright red or yellow to remind you to turn on the water. Or you could put both on a power strip. Leave the pump turned on. When you turn on the power strip to be able to operate the compressor, the pump turns on.

Ken,
Several ways this could be done. Here's one that's dead simple.

Just leave the compressor and pump plugged into the splitter. when you're ready to compress, plug the splitter in. Once done, unplug the splitter. This way, the pump will always be running when the splitter is plugged in, even if the compressor is switched off.
-
Ron.... don't forget your lost shooting time for taking the tanks to be filled... lol
Haha, true that, and the gas too, right ?
But Tim did just recently move his shop which is much closer now (7.5 miles), and JoeB is also very close too.
I have long wanted my own compressor, but current lack of funds will certainly not allow such a purchase. :'(
after reading what you guys have been saying about this set-up,.... and with the current price drop to below $300, it sure has me thinking I may need to sell some stuff that doesn't get used very often.
If I had a semi-portable compressor,
there would really be no justification in having THREE 60 minute tanks, as well as my little guppy tank.
I'm thinking if I sell one of the 60 minute tanks, and maybe a couple of my frankenguns, that would probably cover the costs of the compressor with all the filters/mods/upgrades.

At the time I bought the omega, this compressor was not on the market. Paid $1900 for the omega 😳 That hurts. I could have saved $1500 by buying this and I would have bought it too late now. For me I would buy again😎
All good info here, Thanks !
All of my non-regged PCP's are 3000psi max/2500 sweet spot,.... (except for my bottled XS60c conversion), which is a 1500psi max fill. My regged guns are all bottled 22XX based "Franken-builds", so they also get a 3000 psi fill in the Ninja bottles.
So that means my SCBA tanks basically never go down below 2000/1800 before getting topped off.
Keep the good info coming guys !
It's stuff like this that makes this place a great place to learn.
looking forward to seeing results of costs using the Kill-A-Watt (Please, Please, Please) ;) ;D ;) ;D

For you guys/ gals that have the yong heng compressor, is there a way to hookup the water pump when you turn on the compressor? Just wish that the water pump was inline with the on off switch so I will not forget to plug in the water pump?
ken,
liked we talked earlier, the switch contacts are at max rating when the compressor motor is operating. a pilot duty relay can be added in that loop to operate the pump through the relay contacts. its a simple circuit design..but care must be taken.
i can send you drawings for this upgrade and a pilot relay can be obtained through
your local radio-shack or even an appliance repair shop.
also note that a 120v hourmeter can run in parallel with the pump to give you operating hours.
thanks,
john

Ken, thanks for the piston ring durability test :-\. The water pump only cools the cylinder, so worse case scenario a new cylinder/piston/rings. I'm guessing you probably did some ring damage at least, the water lines popped off from steam pressure...she was HOT. Keep an eye out for trouble reaching 4,500psi, excessive fill times, or tripping breakers.

Oh forgot to mention, the other day had a brain fart. Going inside to have lunch so I unplug the water pump while I take my lunch. After lunch I was filling a hatsan air cylinder that was i setting the regulator. I turn on the compressor. I have a flow indicator inline on the pump hose that spins to let me now that the pump is circulating the water. I forget to plug in the water pump and I didn't pay attention to the temp gauge. Compressor is filling the cylinder to 200 bar. I'm plinking while the cylinder is filling. I smell something was burning. I look over at the compressor and realize I forgot to plug in the water pump. My cylinder did fill to 200bar. I look at the temperature gauge reading 100c😳 I plugged in the water pump and the lines blew right off in the compressor😳 I reconnect the hoses and this time the lines stay on. I felt the water and it was very hot so I replaced the water with fresh cool water. I watch the temp go down down to around 20c. I thought for sure I burn up the compressor. Thinking I did I was ready to buy another. the compressor cooled down, I turn on the compressor and water pump and filled the gun I was filling it to 200bar no problem 😳 I'm still using the compressor. This is one tough compressor 😳

Thanks for posting this story. When running these compressors, constantly watching them is key. Let this be a reminder for all of us.

Close call for sure😳

John I would like a drawing on how to wire it with the on/ off switch along with the hour meter. Wait until you get your compressor so you can have a look inside by removing the cover.

will do, in the meantime, look for a 120vac coil relay with contacts rated around 5 amps or so. that has a fixed bracket mount as part of the relay housing. this is very small and similar to a bosch style automotive relay.
i can get you a supplier and part# tomorrow at work.
will let you know soon.
thanks,

I got a note that shipping wasn't included in the offer I made so I cancelled the offer.
I've not received a response yet....
I had gone back to review my order because I forgot to mention I wanted a 110V plug and there was mentioned that free shipping wouldn't be available.
So go back and review your order with the shipper.
-
Just received a counter offer. $260 I pay shipping ::)
I'll keep watching, sooner than later the prices will drop.
-
John/ bill what a great idea That away I won't forget to plug in the water pump👍🏾😎I think everyone who is using this compressor should do this to your compressor. Another thing to add is an inline water flow indicator that I bought on eBay. I don't remember who it was that was posting in this thread had a link to amazon an inline flow indicator. As you might know , I had a problem with the water pump that came with the compressor. I have had this compressor get hot but not near what it did the other day. For some reason the pump lost its prime? I simply took the pump out of the water plugit back in and it started pumping again. While I have the compressor on I can see the paddle wheel turning and I know for sure the pump is working except the other day. Had a brain fart😳 to be honest this compressor has gotten hot twice. Good idea to have it on a strip and water flow indicator

John the power strip would be the simpler but I would interested adding an hour meter
-
Man... If that thing got hot twice and is still plugging away it's a real trooper. I would certainly keep an eye one it. Make sure your not pumping oil into your guns.
-
Watching with great interest.
I did not make it ALL the way through this thread, but I did read the first 5 or 6 pages, and then the last 5 or 6 pages.
If you don't mind, would you guys be so kind as to save me from pages and pages of reading though all the sidebar stuff, and answer some questions for me ?
From what I can tell, it seems you guys that have these compressors, are pretty happy with them ?
Has ANYONE had a serious mechanical failure with one yet ?
Yes, http://www.talonairgun.com/forum/viewtopic.php?f=52&t=35895&start=220 (http://www.talonairgun.com/forum/viewtopic.php?f=52&t=35895&start=220) This dude had one straight blow up. page 12.
Has ANYONE had to do a rebuild/reseal yet ?
I have on mine. Burst disk blew, on/off switch fail, rear motor mount broke in transit, on my 2nd set of 2nd stage rings... but it still works (sort of) Currently I need to get another 18amp push button breaker so it will fill to a full 4500psi. It trips at 3900-4000 right now due to a tired breaker.
I see that several of you have also added the Gold Colored filter from AliExpress,... and then MODIFIED the filters to perform better.
Havent used any auxillary driers yet. Probably need to...
Is this proven to be working better for those of you who have done it ?
cant say if it works better but I have inspected the inside of my bottle twice since I got my compressor in april, I see no signs of corrosion.
I bleed the HP side ever 2 minutes.
There was also some chatter about a Black filter on LOW pressure side. is this also proving advantageous ?
What other details of pertinent or critical info do I need to know ?
even though I have the tuxing, the inner workings are the same. I have had several problems. It's like a catch 22. If you don't maintain it, you may have issues. If you mess with it even to clean it, you may have issues.
Has anyone looked into feeding the input side with shop air pressure ? (100-125 psi) or is it even necessary ?
Haven't tested it but someone said they did and it couldn't do the job, even feeding it as low as 25 psi. I'll try to find the source on that one since I am going off of the top of my head but I think it is in this thread
What is the total cost for those of you with the Compressor, Filters, Modifications, etc. ?
Has anyone hooked up a kill-a-watt meter to see what it costs to run one of these on the 110v ?
I haven't but I should have just gotten a 220V model. I will likely get another on that is 220V. Half the amps for the same power output.
Won't make your power bill cheaper but I think the motor will have better longevity.
If everything is positive on these little compressors, I may have to put a few AG's, a Hill pump, and maybe even one of my (3) 60 min tanks, on the chopping block classifieds to fund one of these compressors ! ! ! ;) ;D
Thanks for any replies to my questions.
-
Bill I did check oil level and it is still full. I am going to change out the oil and see how it's looking. 10-4 on checking the black filter. Going to do that tomorrow.
-
kzz1kaw, you have the flow meter and still ran it without flow??? As Scooby or Shaggy would say, "Zoiks"! Hope your longevity doesn't take a hit. Keep us all posted.
I don't ever leave my compressor while it's running. I sit next to it and bleed it every couple of minutes. No, I don't stop the compressor to bleed, I just crack each bleed screw on mine and tighten it back up and keep on rockin' on.
I did have a slow leak with my male to male foster fitting I use to fill through the fill whip on my tank from the fill whip from my Gold HP filter. Actually, I think it's the Chinese female foster adapter rather than the male/male fitting. Even still I filled my 2.17 liter tank from completely empty to 4500 psi in what, 23 minutes? Lots of bleeding during the run to keep the moisture from getting out of control.
Hit the dude up on fleabay for $200 offer knowing it'd be declined but I wasn't serious anyway. He came back with $260 and that would be shipped. A whopping $8 off his auction price.
-
Biz yeah it happened even with the flow meter. Sh#% happens when you have a brain fart😳 The compressor was right next to me on my the deck as I was sitting plinking away. A quick glance between shots i look at the gauge. It was towards the end of the 200 bar fill when I smelled something hot by then it was too late. Never say never as it can happen😳 The power strip is a great idea which I will use. From now on. For now the compressor is still pumping away. I will have to monitor the oil level and black filter more often. If she dies on me well I'll just buy another since the prices are dropping and keep this one for spare parts. I have to say this is a tough little compressor 😳
-
Pulled out the tampon in the black inline filter. A dark discoloration from the input side none on the output side. I estimate 12 fills since the incident. I replaced the tampon with a new one. Changing the oil before i start plinking and buying a power strip.
-
To me this is kind of a confidence builder. I'm sorry you had to be the "lab rat" but it sounds like this little compressor can survive an (oops).
However... Since I was fortunate enough to have the AirMax Extreme MKII dropped in my lap (Thanks again for making that happen GTA), I'm looking at the portable 12v systems. Very compact and powered by your 12v vehicle batteries, whether it be your truck or 4-wheeler/atv/utv.... whatever. The also have an a/c adaptor for campground/cabin/home use. The price is up there but, like anything else, it will begin to come down soon enough.
-
I can stands it no more, gots to know whats inside my Yong heng!
I pulled it down to the bottom end. Of course I didn't take picture's :-[
Removed all the stainless tubes, the fittings were TIGHT!!!! a very large china man must have assembled mine! Also, some needed adjusting to fit without putting pressure on the line when I reassembled. EDIT, you'll need 14,17 and 19mm wrenches for this part.
Removed the 4 very top Allen bolts. pulled the top part of the cooling head off. two O rings seal this, one small reed valve in here as well. removable water jacket sleeve sealed by two O rings on the head as well. EDIT, 5mm allen wrench for all the second stage head bolts.
Next I removed the 4 Allen bolts that hold the second stage head in place. the head is sealed with a paper gasket, take care you don't tear it. once off, you can see the second stage piston and seals. This is probably as far as you would need to go for a "normal" rebuild. inside is a reed valve and two locating pins that hold it in position. These pins also locate the 2nd stage head, take care you get these aligned during reassembly.
I then pulled the first stage head. 2 Allen bolts and again a paper gasket. The head slips right off the piston, compressing the rings to reseat the head is easy. Again, you don't need to go this far for a "normal" rebuild. EDIT, 6mm allen wrench for these 2 bolts.
everything looked good, 1st stage piston rings had some very minor carbon build up. Second stage rings looked fine as well with some minor "black gunk" coating the rings, piston and the top of the piston. There is a little reed valve on top of the head mentioned earlier for the second stage piston, it was also dirty with the same "black gunk". The reed valve between the first and second stage heads, this was clean. Both heads, had clean and shiny piston bores.
Some very minor corrosion in the water passages. I attribute this to the tap water I used at the very beginning. I'm now using distilled water and water wetter that has corrosion inhibitors in it.
Put it all back together using a lite coat of diver grease on the few O rings and second stage seals. It still works ;D
Know that I know for sure the Tuxing and Yong heng are not all that close in parts, I went looking for Yong heng parts. found these links.
I believe these are the second stage seals for the yong heng.. I'm ordering some today, you'll need 3 for a rebuild.

John you da man👍🏾 I went on fleabay and AliExpress couple weeks ago looking at buying a rebuild kit as spares. Couldn't find anything for the yong heng. Found the tampon filters that's it. I put in the search bar for both sites yong heng compressor parts/ rebuild kit nothing.
-
What made you decide to tear her down 😳 Looks like I might have to tear mine down maybe😳
-
Good info there john. Do you have a tuxing compressors to compare the two?
-
Change out my compressor oil smells burnt. Dark in color. Yesterday I did top off to 250 bar on my taipan and cricket pups with no problems.
-
Ken,
Honestly, its unusual for me not to tear something apart when I first get it ;) I've held off out of fear I'd screw up something on the compressor!
My compressor was and still is running fine. No reason to tear down other than curiosity and wanting to see first hand how some of the Tuxing parts compared since that was all I had been able to find until today....
I do not have a tuxing, so, all I can go off is pictures I've seen of the tuxing. The second stage heads do the same thing but are NOT the same. The second stage piston on the tuxing has 4 seals, 3 on the yong heng, again not the same. Not sure if the second stage seals are the same size or not for both. I think the second stage seals I just ordered are the correct ones for the yong heng.
The first stage heads do look the same between the two, not positive they interchange though. The first stage pistons look the same, again not sure they interchange. I think I have the right first stage piston linked for the yong heng and on order. I'll know for sure once the items deliver... Oh, not sure the Tuxing connecting rod would work either, it has that pointy piece sticking out off the bottom end, the yong heng does not. I think all this is for is slinging oil better...
If anyone happens to find the two reed valves, please post them!!!
I'm not surprised your oil smells burnt after hitting 100c. I'd bet the first stage piston, rings and possibly cylinder are scored a bit....
Edit:
Now that I've had mine apart, seen first hand how simple they are and found parts.... I think I'll pass on getting a spare compressor.
with the seals I ordered and a spare piston, I think I can keep this little feller running for a long time.
I might order that complete head assy soon though...
-
I ordered the complete upper end I linked above just now.... said "limited quantity" during check out, so, I had to buy one before they sold out! ::) ;D
-
John thanks for the info. I am going to order piston, rings and seals just to have as spares but in the meantime I am wondering how long this compressor will keep on running? The old saying if it ain't broke don't fix it😳

Ken,
I don't want to alarm you but, the catastrophic tuxing failure in the link posted by Jman.... I can see this possibly happening to your compressor.
If I understand what happened to wingman's Tuxing. The 1st stage rings were worn, allowing oil to enter the second stage and diesel. With your compressor getting so hot, and likely damaging the 1st stage rings at least somewhat, I'd be pulling it down to inspect those rings.
I'm not sure what oil wingman was using, this may have played a big part in that failure. I don't think the synthetic oil I'm using will diesel, even at the pressures and temps we're seeing, I'm not sure of this though. I think you're using synthetic as well?
-
I have it on good faith that there are 2 Tuxing compressors sitting on a specific retailer's bench in heaps... The remainder of his inventory was returned for credit...... just sayin..
-
John just ordered a piston and seals just in case but for now I am going to run it as is being that it is still working for me. Knock on wood 😳 If the compressor decides to quit working, I still have my omega as backup until I get the parts from ali
-
Bill I did hear about junan I think that is his name tuxing compressor having issues but I am not aware of another tuxing compressor problems?
-
Two guys buy identical Mercedes Benz. They leave the dealership at the same time, one turning right and one turning left. The guy who turned right drives his MB trouble free for the rest of his life. The guy who turned left is towed back to the dealership 20 minutes later.
-
Bill I am that guy that bought an mb and drove it for life ;D
-
Bill just because I typed my response I probably jinxed myself😳
-
So I take it they don't send extra rings and such for 1 rebuild? I was under the impression spares were included? Cheers Jaa
-

Jay,
Yes, the needed O rings, bonded washers and a couple of delrin? seats are included. This would solve any water or air leaks at the bleed screws and fill whip. My "rebuild" kit didn't include second stage seals. No parts for the first stage are included either.
-
Ok thanks when I a pump, I'll order some spare parts. Thanks Jaa

Ken,
I understand. I've broke things that were running perfectly because of my curiosity taking them apart...
I hope I didn't steer you wrong on the parts, I have the same on order. I think they'll fit, they look right anyway....

Hi everyone,
I've been following this thread considering obtaining a compressor myself. I was searching Aliexpress and it appears there is an upgraded version of the compressor. The latest version for sale appears to have the following:
-water tank (maybe a gallon capacity guessing from pictures)
-temperature buzzer/alarm
-low pressure safety valve
-low pressure gas storage filter cylinder
-"waterproof" on/off switch
-additional motor mounting screws
-optimized fan
I would post a link, but I am not allowed to yet. Searching "pcp compressors" on aliexpress will yield the same findings.
I'm not sure if the included water tank would suffice for cooling but it does look convenient as a package. Nonetheless, it looks like "improvements" or updated versions are in the works.
-
Soon I will be putting my YH to the test, I'm planning to top off my 6l 300 bar scuba tank. My air dryer/filter setup is almost ready to go, only needs hydro testing.
Has anyone else noticed that the YongHeng gauge glows in dark?
-
Yep. As does my generic fill whip valve assembly gauge.
-
Although I'd never use either in the dark. :o
-
To me this is kind of a confidence builder. I'm sorry you had to be the "lab rat" but it sounds like this little compressor can survive an (oops).
However... Since I was fortunate enough to have the AirMax Extreme MKII dropped in my lap (Thanks again for making that happen GTA), I'm looking at the portable 12v systems. Very compact and powered by your 12v vehicle batteries, whether it be your truck or 4-wheeler/atv/utv.... whatever. The also have an a/c adaptor for campground/cabin/home use. The price is up there but, like anything else, it will begin to come down soon enough.
I also am looking at the convience, and portability of the 12 v systems, just be nice to have an option if I can not pay my electric bill ,, due to another airrifle purchase j/k . Just the prepper mind set I was raised with I guess :-\

James.... you just increased my reason to look after the 12v version 10 times.... I din't even think about things like power outages and such.... You just don't know what wait around the corner. A 12v hpa compressor puts the pcp right back in the "wtshtf" kit. I may not be physically able to cock a springer or a pumper but I'm pretty sure I would be able to slap a couple alligator clips on a battery from an abandoned vehicle. Then stuff it back in my wagon.
-
Has anyone else noticed that the YongHeng gauge glows in dark?
I noticed the glow, the first time I turned off the lights in my shop. A little odd, but maybe useful if the breaker pops
and the compressor stops as the lights go out. You can still find your bleed screw in the dark room, it's right under the meter.
I was worried about forgetting to turn on the water pump. So, each time I unplug the pump,
I put the cord around the handle and lay the plug almost on top of the power switch..
-
Yes rich don't have a senior moment and for get to plug in the water pump 😳 Bought me a power strip and use that to turn all at once and off when I am done😎 Mines still pumping away today filling my guns😎
-
Is the cover easily removable? If so why not wire the pump cord into the switch.
Norm
-
You may want to leave the water pump running after the compressor is off to bring the temp of the head(s) back down.
-
You may want to leave the water pump running after the compressor is off to bring the temp of the head(s) back down. To prolong the life of the compressor. All of our industrial compressors keep the fan and coolant pumps running until ambient temp is reached.
-
Hmmm very good point as I did not think of that
Norm
-
Good point. Since I had my compressor overheat, I rather use the power strip to turn it on and off
-
I have my space all ready (complete with power strip) just waiting for the Big Brown Truck to arrive Today. Really going to be hard to return to work after my lunch hour.
(checking available vacation time)
-
I ordered mine, the one for $269 from huazai on ebay. Chemlube, high side filter, and zeolite are on their way as well. ;D
Thanks to everyone who reduced the risk for me. ;)
-
So far compressor still filling my guns to 3k tough Little compressor 😎

Did you order a Cylinder with your rebuild parts? If not I would be causes, You don't want to Score your cylinder, That way you can just re-ring it, And put it back together ;) You have a back-up I think I would use it. Cheers! Jaa
-
I would just use the darn thing... the price is getting low enough now that by the time you order the parts and all the headache you could just buy another one and have one for parts. Just make sure you not pumping corruption into your guns.
-
I had just thought that Kazz had another compressor, If so Why trash something if you don't need to??
-
You know... you're right.. I forgot he had the omega...
-
My YH is out for delivery !!
Should be there when i get home from work........ 8)
-
Nice..... let us know..
-
Late to the game on these cheap compressors - I was always looking at the Shoebox.
Anybody have a nice laundry list of links to get a full setup going? Compressor, driers, hoses, mods etc? I'll read the thread but it's 48 pages now .... :-)
-
I'm just using mine to top-off my Prod and my At44, I don't shoot a lot pellets per-day..
I bleed the compressor often, as I add air to my guns, and not seeing much water signs..
So, I'm not yet seeing any need to buy a bunch of extra stuff.. (I did have to buy the required oil).
-
High side dryer is absolutely necessary if you want to fill scuba tanks, my experiences show that the air has large amounts of water if compressor is used in humid conditions.
I you want a rough estimate of the water content, fill a transparent plastic bag with the compressor, seal it and put it in the freezer, after cooling you can easily see the amount of water per air volume.
Does anyone know what is the first stage max pressure ?
I want to put gauge in there, I have a feeling that my compressor has bad 1st stage rings as it doesn't fill as fast as it used to but still goes to high pressures.
And a little sidenote: Do not trust your yong heng pressure gauge, mine shows 30 bar less than the actual pressure.
-
Nice..... let us know..
well Bill, what i received today was a small e-packet from china with a silver coin in it.
the label says for price paid for pump.
has anybody else received this as a notification of future delivery ? or have i been
COINED........ :o
-
Huh😳
-
YEP..... tiny bubble pack with a silver china coin in it. ???
-
I don't understand 😳 You paid for a compressor from eBay? Does the seller have good feedback?
-
I would contact the seller and ebay😳😡
-
I hope you have not been coined 😳
-
That is crazy😳
-
here is the item# of an updated listing with different price... 182665900863
i have tried to contact them, i'm waiting responce
ebay and paypal are next
-
Shows the seller has 4 positive reviews. Has the payment been paid? If so, you will get all of your money back. First time for everything hope you get it resolved 😡

yes paypal payment before ship, he had 83 transactions with i think 95+% rating
it showed 23 pumps have been sold.
now to play the ebay waiting game, 8/10 before they step in....and paypal waits till
ebay folds on contacting the seller ::)
-
Well rest assured either way you get your money back. I know it doesn't help you out being that you are already waiting on it to arrive. 😳 Kind of leaves a bad taste in your mouth😳 Don't let one bad seller discourage you. There are others selling the same compressor. Don't give up yet!
-
There are others selling the same compressor. Don't give up yet!
yes, i see that...and a few of them have the same pics as topse.666 had.
and they even have the same stuff in there store also...kinda makes me leary
of another BS scam. >:(

I happen to agree with this but I realize this is still early on with these particular compressors.
Hopefully as more are bought, knowledge will be collated in a meaningful way.
There is a lot to like about these and should cause the price of other hpa compressors to come down some.
It seems to be specialty-priced on other compressors..way higher than they should be.
Makes me wonder why no US company is trying to build them.
-
because the US don't build stuff anymore... We buy the parts offshore and assemble stuff.

Its the high pressure side thats leaking, it will blow by oil if the first stage is shot.
Most likely when you pull the head there is black soot in the high side rings.
Marko
-
It could be the second stage but it has some oil in the filter and second stage check valve looked clean except for the water. I measured the fill rate when compressor was brand new and it was 0,456 l/s, I will check what it is now.
-
I ordered a YH compressor as a backup for my Tuxing setup from the same seller as GenDoc has noted receiving a coin and not a compressor. That order is shown to be in US in transit and does show "epacket" on the shipping information. I would suggest that anyone contemplating an order for one of these compressors refrain from doing so until my order is delivered or at least contact those who already have a YH and order from those sellers only. I will post what I receive as soon as it does arrive but it may save some people the trouble of pursuing this with Ebay and Paypal.
-
Ok, that's strange, usually the normal piston rings start to seat better with some use.
Could be a scratch in the first stage.

sounds very familiar....
i ask the post office this morning if they will deliver a crated shipment from china, they said if its within weight limits they will. but most likely will be a pickup at post office.
but an "epacket" is a small padded envelope the postman said.
good luck, i hope you get a compressor instead of that worthless china-plastic coin

It was $30 cheaper when I ordered it a month ago. I ordered on Monday and received it on Friday. It was shipped from California, not China.
-
Well your seller is not in the good old usa anymore, You have to remember your dealing with the chinese! Here people. They will set-up an office here or a relative's home, With Little to no Stock, They Take your payment that could very well be sent to a Cal address, But your order will in fact be sent from China, I just went through this with a seller on Ebay myself 3 months ago, It was for a Hand Pump, My Cali seller stated in stock. It was in fact 3 1/2 weeks before I receive it. The USPS is slow But Not that slow Sorry, I would advise anyone that orders chinese items to CONTACT First and get ship times in writing when they claim the item is in the usa. More Ammo to use with paypal for a claim! Their SNEAKY Little s&^%'s. Here's the address on the Link You Posted.

I guess that a lot of us lucked out in getting the compressor in less than a week but we paid a little more for the it.
I have had mine for a month now and t's still going strong and I never allowed it to go over 55 degrees C. Bob
-
Good catch. I missed the fact that the seller is now shipping from China. I guess I must have been lucky to get shipment from with the USA and shipped via UPS.

Ran down the pressure in the PRod to just under 1000 PSI..
Put it on the compressor and noticed air leaking around the QD & fill nipple.
Shut down and looked it over and everything 'looked' fine.. Restarted it and held the QD and presto, no leaking..
It took all of 20 to 25 seconds to fill to 3000 PSI. On a small reservoir, this thing is fast!
I really have to watch the gauge and be ready to stop filling.. I vent and switch-off at about the same instant..
Found no moisture under the bleeder. The RH in the basement was 44% at the time..
I've not shot the AT44 enough to refill yet.. I assume it's going to top-off in under 60 seconds.. :P
Cheers,
Rich

Had my first scare today. Not the compressor's fault. I was filling my 2.17 liter tank per the norm when a loud hiss comes from my scba valve. Scared the poop out of me as I was NOT expecting it. Turns out the fill station valve that screws into the main bottle valve had a chitty oring in it. The fill station valve has a hand tighten means of threading into the valve and it allows for a bit of pivoting action of the attached pressure gauge. This may have allowed a knick or weakening of the oring. The oring failed under pressure of about 4200 psi.
Quickly I shut the compressor off and closed the valve on the scba tank. Air pressure continued to hiss out and I noticed a bleed hole in the main valve which I believe is there for this very purpose, should an oring fail. Not sure if that makes sense from a safety perspective or not. I guess so. Assume you forget to open the main valve on the tank and begin to fill and get above 4500psi. There is no burst disk at this union but perhaps it's designed to have the oring give way and has a place for the extra pressure to exhaust itself to nothing blows up? Make sense?
Anyway, after the remaining pressure in the fill whips and big High Pressure Gold filter had evacuated I removed and replaced the oring with a new one and all was well. Hooked it back up and filled to 4500 psi without a hitch.
From now on I'll be monitoring that oring.

Yep really gotta watch these sellers closely, I will be buying one when they start listing some parts on Ebay as I will not use a credit card on BangGood or whatever it is, PayPal only for me, I already had 2 cards that had to be cancelled because of unauthorized transactions, That were caught by my card holders and notified me, Thank Goodness. It still was a pain to clear up. So I no longer throw them around like I used to. I have emailed some of these Ebay sellers to start listing some parts for these compressors, Or I will shop elsewhere! What good is a vendor that has no parts for sale? I would encourage all to do the same, It only take a few minutes of time and will insure you can get parts! And that should help weed out the Fly By Night vendors of these. I don't care if it ships from china or usa, But PayPal only for me! Cheers! Jaa

Oh dear. I received DHL notification for today delivery. I don't think it said e-packet anywhere. I hope I don't get a coin. The delivery did require signature. I don't think they would do that for a stupid coin. Will post what I find when I get home from work. Mine did ship from China, but is about 2 weeks earlier than I expected.

AliExpress is selling parts for the yong heng. Have to go back couple pages. Look up Shultz as he provided links to the parts on AliExpress. I ordered parts for as spares just in case😳
-
Dang!! I just checked. I think that is the high side filter arriving per DHL today. My "compressor" is still in China and is shipping epacket. Bummer. Have to wait a few more days before I can start getting my $ back from e-bay/paypal. Oh well. Anyone want a shiny coin from China? I'll sell it cheap.

It was China that in fact that Hacked or Breached the IRS computers a 3-4 years back, And stole our tax returns, Millions of them. That resulted in the addition of 3 more digits to be added to the end of some people's current Social Security numbers. Lots of individuals did not receive their tax returns until almost Fall that year. Is that what that is referring to? A bit long of a read for me right now. Jaa

The OPM data lost is a lot more extensive. But, it's not a problem unless you have close friends, a neighbor or close family who held or now holds a top secret clearance.
If you ever filled out the SF86 form, you are compromised. Hackable or Blackmail bait for Chinese agents.
In normal times, you would never be allowed access to TS materials again.. (likely fired).
I do have 'free' ID protection provided by the USGov now.. Until someone hacks their database.. :(

My e-packet did contain that silver coin but at least it is marked as "1 oz ag" so I've got that going for me. Surely it is pure silver, right? I did use ebay and paypal so it should all be handled and refunded but I would like to have had the YH as a backup compressor for that price. Hope all who have the YH compressors are having good luck with them and I hope further orders from other sellers continue to be delivered reliably. I'm still using the Tuxing with fine function so far.
-
Oh so now its a gamble do you get a compressor or a coin, it used to be do you get a lemon or a good compressor, maybe they are out of bad compressors and need to keep the statistics anyway ::)
No seriously that is effed up business!
Hope you guys get your money back.

No, not the case there, negative Marko. But I did mention somewhere a person should never buy from a seller who willingly places a "666" in their name.

Strangely seems like a play on the "bitcoin" scam.

Well I finally got to finish the up grades to my Yong Heng Air Compressor. Changed the lube to ChemLube 751 , built the pvc filter , filled with desiccant beads, used a 5 gallon bucket filled about 3/4 , small bag of ice in water. It took about 20 minutes to fill the Air Venturi Carbon Fiber Tank, 90 Cu In tank from mt to full . Watched temp guage on compressor and it did not go over 46.3 C . When I started water pump I placed the return line as close as possible to top of water line, made sure all air was out of system. Turned on compressor all went great. When I opened high side vent and turned off compressor did not see any moisture or oil residue.

Hi all, Just boght one of these compressors and have been looking for a soloution for the hose it was shipped with. I has a 8mm female quick disconect! Reading here, no one seems to have been shipped this with there compressors. so my question is how to make this M.10 Threaded hose with the 8mm female foster work for 1/8th male? Please HELP! :-[
-
Joey,
I'm a little confused. Are you saying the stock compressor quick disconnect won't lock on your gun foster fill nipples? Or are the compressor hose> foster threads the problem?

It fits. Did you try it?
-
I will try and be a little more clear: No it will not fit my gun's fill port. all of my guns use some type of 1/8th connections wheather it be female or male. the commpressor I bought was sent with hose and filter. the female QD is 8mm. will not fit on a male 1/8. this is where my issuse begin.
-
You say some of your guns have FEMALE foster fittings? how can this be? Do you have any pictures of the fittings?
Yong heng or Tuxing compressor?
I've not seen any issues really with the foster fitting included with the yong heng. Will it not slip over your fill nipples at all? or, is it just not locking in place?
Another poster had QD fitment issues. His was a Tuxing compressor that uses a male foster off the compressor head to attach the hose. He ended up buying an Air venture, double female foster fitting micro bore hose. This option would not work on the yong heng...
-
The "Yong heng is the one I have. and no it will not seat all the way over my airguns probes or over an aiforce Talonp's fitting ("Spinlock")
-
Sorry I did say female. that is not correct. I have no gun that has a female connection. only probe and male foster.
-
Pics pics pics
-
Huh, This is the first one I've heard of that didn't fit right.
Unfortunately, not a lot of options since the hose thread is M10x1.0.... you gota use a Chinese foster for direct thread on...
However, you might try a local hydraulic shop. If you can find a female M10x1.0 to either male or female 1/8NPT bushing that's rated for 5000+ PSI. This way, you can use any of the good quality 1/8NPT foster fittings. I like Ninja brand myself.
Worst case, I have a couple extra, M10x1.0 Chinese female QD's that have fit any fill nipple of mine I tried them on. I'll send ya one if you need it.
-
Just had a thought....scarry :o
If one of the little balls in the foster is seized, it won't move when the locking ring is pulled back, and the fill nipple won't slip in.
Take the little silver split ring off the end of the foster. Slip off the locking ring, watch out you don't lose a ball!!! make sure all of the little balls can move freely, then reassemble and give it another try.
Edit:
Tip, a little silicone grease on the balls will hold them in position until you can get the locking ring and split ring back on...
-
Pushing in harder to smash down the oring in the female end won't work? I've not had the best of luck with the "8mm" females either. They work for me, but some probes leak and some don't with them. I decided to buy the Airventuri female foster fitting that's terminated with 1/8"BSPP female. I needed an M10x1 female to 1/8"BSPP male fitting which I could not find made ANYWHERE but one guy on ebay. Guess what, he lists it as 1/8"BSPP but it was made as a 1/8"BSPT and am fighting with him through ebay over a $12 part as he claims I'm wrong. In the meanwhile I had our cnc guy at my work whip one up for me that fits perfectly.
Good luck. Take up shultz on his offer to send you his female quick release.
-
Thank you Shulz Please send me what you can. I would be very Greatful. I Just don't see may saying they are haveing this same issue.
-
There it is the 8mm attached to the air dryer and heres the commpressor.
-
Joey,
See if its just one of the balls seized up, simple fix if it is. If not, PM me your address ;)
-
I ran into two problem with my DIY adapters. I used cheap Paintball shop connectors.
They worked fine for filling guns with my scuba tanks and my two hand pumps, but would not fit 'click into' the compressor QD.
I replaced two of the paintball connectors with new parts from Amazon.

I need a little help fellas.... I received my complete yong heng compressor head today. WHERE does this go :o ;D

Head looks fine, from what I can see, it's the exact same head I already have on my compressor. Not bad for $90 shipped. Even included the paper gasket. And of course the cat bell..........

Somehow, my second post with the head picture, ended up before yours asking if the cat bell was all I received.... ???
Anyway, No coin for this guy, yet.....
Still have the complete piston assy, second stage seals and accy kit coming though...

Yeah, I hadn't seen the second post when I asked.
Glad you got what your ordered. I've ordered a couple things from China since this &^^& began and I hesitate every time.

Now that's an idea! only got 25yds.... be right back ;)
done! took me 3 though :-[ First shot miss, second knocked it off my pellet trap but didn't hit the bell, third time finally got it ;D The sky is about to open up here and its probably blowing 10-15 right now.... 8.5gr H&N sniper medium, hit just below the clasp.

I bought mine from these folks located in CA. Ordered on Friday afternoon, shipping notice on Saturday, picked up by UPS Monday morning, delivered to me Tuesday afternoon 8) I asked the seller a couple questions as well, responded each time.

thanks for the links guys, i've messaged both sellers to see who has them in stock in
the U.S.A. ;)
-
hey John.... make an offer something less than the posted price. Might save you another $20 or so. No harm, all they can do is counter offer or refuse. Maybe even ask for an inline dryer to sweeten the deal.
-
soon as i find out they have them in stock in the U.S., i will do that !!
i believe both come with the black oil/water separator.... i have 2 of the gold filters
ready for when i get a compressor ::)
-
John,
Sometimes it takes a while for them to respond to an offer. So, check their page for a notice that says,
"62 Sold. Only 3 Left". You might miss out. I've had that happen to me a couple of times.
You also have to look closely at the dealer. Has he been active, does he have a lot of good reviews?
I wanted to buy a real bargain GPS last week, but was leery of the price. It was a little too low.
Dealer reviews were few and very old.. So I watched for a while and saw they were selling fast.
Since I have paypal, I placed an order. 205 units were sold. Waited for a week, nothing.
Ebay notified me it was a hi-jacked account. Full refund.
-
North Koreans at it again? oopps, my bad.

Just got confirmation from nice-shop the YH is in stock and ships from California.
I just ordered one...... ;D
-
oop's

Sounds Great !!
Just a tip...
Use a full 5gal bucket of water for cooling and keep your return hose as close to the top as possible and your pump at the bottom. I even have my return just above the water line.
-
The eBay nice-shop listing I see does not mention shipping. What have you guys noticed from them?
-
Are you talking about my ebay link for nice-shop2?
Add states free shipping, my compressor from them came via UPS in a VERY sturdy card board crate, I wouldn't call it a box...
-
Hopefully the seller is upfront and delivers as promised
-
What is the oil capacity of the YH pump ?
-
roughly 300ml. One quart will do 3 oil fills with a tiny amount left over.
Edit:
Tip for oil changes. I found, that the rubber crank case cover gasket will hold some oil in the crank case and crank case cover even when the compressor is tipped up on one end and stops draining oil out of the drain. So, I recommend, draining out all the oil that will gravity feed out. then get some rags under the cover and remove it to get the remaining oil out. I also wipe out the crank case and cover with a clean rag. I would do this for at least the first several oil changes as things break in... nothing worse than adding clean oil to 25-50ml of DIRTY oil....

I received notice from eBay that they have refunded my purchase price for the compressor to paypal. I hope the same happens for all who ordered from that knothead. I also had sent an email to the nice-shop folks that schulz had linked and they noted they have compressors in California ready to ship so I'll order one from them.
Also as noted above, the crankcase on all of these compressors seem to be basically identical and my Tuxing also retained quite a bit of oil along the gasket. I had removed it to clean it out before initially running it and noted the oil pooling so I agree completely on removing the cover and cleaning the crankcase well at oil changes to remove any wear elements that might settle there.
-
No problem, the rags part is the best tip....
I removed the cover, wiped out any factory oil and looked for any "chunks" before my first oil fill. Once I ran the compressor a bit, I drained out all the oil(or so I thought) and put it on my bench to once again, remove the cover and wipe out the crank case. The remaining oil ran out on my clean work bench.... :-[

Well I hooked up the pc radiator I got in. I haven't had time to test it yet and probably won't for a couple days. I'll try and do these tests,
Baseline no radiator
Fan off
Fan on
Ice pack fan off
Ice pack fan on
Damp rag fan on
I think I'll run it 10 mins each test filling my guppy from 3500psi and recording the ending temp of each run.
Jason,
How did this work out on your setup? I see you were going to do some testing, but I didn't catch your results if you posted them. Just curious if I missed them.
-
I have a pc radiator and 120 mm fan setup, with 5 liters of water it never gets over 54 c. Compressor warms up faster with radiator than it did with just large amount of water, but temperature stops getting higher. First stage intercooler would lower the temp even further but I haven't had time to build one just yet.
-
Guess what guys? I didn't get a coin. I received a used women's bracelet. HAHAHA
Ebay is on it now. Hopefully I get my $$ back soon. :) Will order from nice-shop2 per your high recommendations.
Thanks fellas.

(Un)fortunately I am moving in the near future so my compressor is drained and packed away. I will have to test it when I get to where I'm getting to. Texas will be a great way to test my gold filter as well :-\ The bad part is I will have next to 0 land to shoot at. Maybe I can talk the wife into letting me set up an indoor range in the upstairs hallway haha! At least until I can make friends with people with property and preferably critters.

Unless you are moving to the middle of a large city, there should be plenty of places to shoot an air rifle in Texas.
I live up north of Boston and use my basement's 10 yard range during the winters.. It's great for off-hand practice.
Hope you like it warm... ;)

Ya'll must not use Ebay often. I've been with them for like 15 years. And in those 15 years I've had LOTS of bad luck. To the point I hate Ebay. I use them as my last resort. I actually went through Aliexpress of all places and feel they are more trustworthy than Ebay. Ebay has pretty much corrected all of my woes, but sellers are pieces of &^^&. Average Joe's trying to make a buck. Scammers making bucks as well. Even have bad luck with sellers with 99% positive rating with tens of thousands sales.
God bless Amazon for internet shopping.
ETA: Sometimes beware Amazon 3rd party sellers. Although Amazon will set things straight for you in the end.

I don't use Ebay a lot, 248+ transactions over 19 years.... less than a dozen of these were me selling. Never had a problem, always got what I ordered in a timely manor and as described.
Anyway, The tinkering bug still has me. I ordered a double, 120mm fan PC radiator and a couple of 125CFM fans for it.
http://www.ebay.com/itm/PC-Computer-Radiator-Water-Cooling-Cooler-for-CPU-LED-Heatsink-240mm-Aluminum-US/311882214307?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 (http://www.ebay.com/itm/PC-Computer-Radiator-Water-Cooling-Cooler-for-CPU-LED-Heatsink-240mm-Aluminum-US/311882214307?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649)
I'm using a 2.5gal Fridge water jug for my cooling water supply. I take it right out of my beer fridge, drop in the pump and discharge line. As is, I can run about 40min before I hit 50-55c and shut down. The cold water also has wetter in it, not sure if it helps with temps or not, it does have corrosion inhibitors, that's my main reason for using it.
If the radiator gives me an extra 15-20 min of run time I'll be happy. If nothing else, for $45, it will be a fun distraction setting up the radiator.

I have been using a PC radiator/fan on my compressor for two weeks now and it seem to help in keeping the temperature down. I haven't measures the temperature deferential yet but you can definitely feel the outlet cooler then the inlet to the radiator. I mounted the fan assembly vertically, on the upper cover, so that the output air flow helps in cooling down the upper compressor stage. Bob
-
Bob,
I plan to mount mine vertical, so it blows across the first stage fins and crank case. I currently use a 250+CFM fan blowing directly across only, the first stage fins. The radiator set up will replace this. A little less air moving directly across the first stage fins, but, the air should be cooler than ambient(at least in the beginning)and I think still enough air moving to not make much, if any difference over my current single fan.
I also plan to cool the discharge water vs the intake. My reasoning. I'm already using cold water for intake, by cooling the warm water returning, before it enters the 2.5 gal container, I might keep the water temps lower for a little longer...
-

Can't say that has been my experience. In 20 years there, Over 1000 transactions primarily purchases! I can only think of 4 or 5 instances where Paypal had to intervene for me over that time frame, And all were resolved in a timely matter, And one was not the sellers Fault, As it was damaged in shipping, But he Stood -Up and replaced it. I have however had more problems with general internet shopping? With a credit card theft and having to close out accounts!! I have stopped that altogether. Unless PayPal can be used!! You have to do your Homework a bit on the seller, If it sounds too good to be true it probably is. I have walked away with no bidding on an item More than Once!!!, Because of the seller, Bidding Or Running their own auction - Having someone bid on their auction. Or Because of information, Such as history, Or description just Didn't look right. So far from what I have seen is {nice-shop2} is a real seller who backs up his words! I will order from him IF he stocks some rebuild parts as well. If not I won't plain and simple!!! If another vender steps up with no Game Playing I will take a hard look at him also! Because in my case ordering from Aliexpress and or using a credit card, Or signing up for some kind of Alipay is a Complete NO No for me!!!!!! I Cringe at the way some people throw their financial data around. That's Just asking for trouble, And it will happen sooner or Latter. Trust Me on That!!!! Jaa
-
I have a 5gal. bucket with a lid on it. I have holes in the lid for the intake and return hoses. The pump obviously sits in the bottom of the bucket and the return line ends just above the water surface. I keep a milk jug of water in the freezer. Maybe 30 minutes before I run my compressor I put the ice jug in the bucket with enough water to be full without sloshing out onto the floor. I've yet to have heat issues since using this setup.
BTW... I have the MRodair MKII dual cylinder 4500 psi compressor.

I am interested on the outcome with the radiator. Do you have a hand held temp gun to measure the temp going in and out?
-
Btw, my compressor is still working after it overheated 😎
-
Tough little compressor😳 I plan on whenever I get the rebuild parts from AliExpress to take apart the topend. I'll post pictures on the rebuild.
-
Bill,
IIRC, your compressor hit about 65c filling up a 80cf tank. That's about 10c hotter than I allow my compressor to get. Heat=accelerated ware.
Now, I don't know for certain what temps are safe to run at...65c might be perfectly fine for your compressor. For my Yong heng, I set my max at 55c to be conservative. I think the manufacture, recommends 60c-70c as the max. Of course, they don't care how fast it wares out or how often its needs a rebuild....
I was using a 5gal bucket with 4gal of water and a one gallon frozen jug dropped in. Yep it stayed cool. What I'm trying to do is get away from using a bucket. The cold, 2.5gal container is getting me close to what I want, pull it out of the fridge, drop in the pump and go. I think the radiator will get me the get me longer run time and still be quicker to set up/take down than the bucket when I need that extra run time.
-

I should have taken pictures... I always seem to think of this AFTER I'm done!
Yep, have an IR temp gun and several thermistors I can use to monitor temps.
-
You are correct John... that was before my current setup... as I should have mentioned.. At that time I only had 3 gal. of water in the bucket and I weighted the return hose because it was spiraled and that weight sunk it to the bottom of my bucket. The current setup is a world of difference.
Sorry for the confusion.
-
Don't forget, You can add food coloring to your water, Sooo you can tell that your water is circulating thru the clear hose's as well while running.
-
I use a little clip to hold my return line and keep it just above the water line so I can see flow at a glance. My water wetter is green, this helps some too ;)
-
Didn't think about the food coloring... I'll have to do that. Someone said they used an inline flow meter.
-

Moi: https://youtu.be/OLX-cFB-XYU
I have since removed the fan as it impedes flow vs aid in it.
-
Bizill,
I have my fan pushing air from the left side of the compressor, across the first stage head. This way, it doesn't fight the motor fan, just moves the air its pushing out, away from the first stage head quicker as well as blowing more cool air across the head. If you wanted to locate the fan where it is, mount it pulling air vs pushing it. All though, the zip ties will either melt or at the very least, be short lived and break as those lines get HOT.
-
I was just thinking about those pre-cooled water tanks.. If you forget to turn on the water pump and
the compressor temperature really shot upwards, would shooting in some 33 deg F water be good for the metal?
-
If the metal were hot enough for the 33 degree water to have an effect on it, other than cooling it... the compressor was ruined long before the water had a chance to do any harm.
Maybe it's because I was use to operating equipment. I simply check things before I flip the compressor switch to run. Aux fan running, check, water flowing, check, all hose connections made, check, high side and low side bleeds open, check. start the compressor, good air flow out of the bleeds, check, close the low bleed, then high, watch pressure build and keep an eye on things.

Wow, that's way too much checking for an old guy.. (like me).. :)
I just plug in the pump, make sure it's in it's tank.. Bleeders closed, check.. Not too complicated or, KISS.. ;)
-
Well, I'm not sure if 49 qualifies me for old guy status....
It only takes me a few seconds to do the checks. To me, this is KISS.
I work with some VERY dangerous chemicals on a daily basis, checks and procedure keep me alive and looking marvelous :D
-
49 is still young John.. Problems start in about 20 more years.. :)
However, you might feel the urge to buy yourself a bright red sports car for your next birthday.. ;)
I retired as soon as I could. Working on antennas up high on towers and lasers in the lab, is just to risky for my taste.

John, you must have been looking over my shoulder when I'm ready to turn the compressor on and copied my procedure, or we think alike. Bob

Bob,
After so many years of running/working on machinery, it's just second nature.
I did leave out one thing, checking the oil level. I do this as I'm getting the cooling water set up...

-
I'm like you as well John, with all the pre-run checks. Too much can go wrong if you don't do them.
I removed the fan from my setup at any direction of flow as I don't feel it helps enough to make a difference. Incorporating twisted copper tubing around stage one fins might help with water flowing through it or it may not help at all. Even if I lowered me by 5 degrees c, then it's not worth the effort to me. I ran 2 days ago and hit 58. I normally keep it below 55 but didn't even worry about it.
And with the fan, yes indeed, I was afraid the hot tubes would melt the plastic zip ties and/or the fan housing itself. I put that fan on in a first attempt before even running the unit and realized just how hot they got. I removed them immediately.
-
Bizill,
I too, thought about adding a simple cooling loop to the first stage head. Like you, I think it would not be worth the effort. I did something similar, MANY years ago when I was running large, gas powered R/C boats. We used 20+cc weed wacker engines, striped of the shrouding that helped keep them air cooled. By coiling copper tubing, between each fin, you got a half arse water cooled head. It worked well enough as long as the water pickup was moving.
If I only need that couple extra C to finish a fill, I don't worry about it either. I just try and keep it below 55c on a regular basis. Might not do much, if anything for longevity running below 55c, It certainly won't make things ware quicker though!

I just bought a Yong Heng compressor off eBay for 236.00 shipped from Los Angeles, Cal. It showed estimated shipping arrival on August 29th. The sellers is loveshoppingjkts with a rating of 97 sales with 97.9%. They show 8 left after the one I just bought. since its PayPal/eBay I will take the risk since they will refund the money if it does not show up Again.

You beat me to the post Mike, this is an amazing price since it seems like sellers are now raising the cost of the Hengs. I don't think I'm gonna pass this one up, they may go a bit lower but I'm ready to play now.

I just sent an email to confirm the location and what plug they have on them. Good catch Jaa

How about rigging up this for cooling the water?
Can't post links?? Search e*Bay for 15 Row Engine Trans 10AN Universal Oil Cooler
Just rig up the hoses? 12v for the fan I presume?

Got a bad feeling on that seller too, fellas. Hopefully it works out...

Works very well.
I have a spare that im going to try cooling my YH.

John, Do you have a cold well on the farm? If so I would run to waste, And just use the waste for watering your plants.

Nice! Is the YH refer to the same one on eBay that's $236 right now?
-
Schploink, I just dove in head first. I tried tossing an offer of $220, but never heard back. I figured not worth losing over a few bucks, now I'm on to the golden boy filter build.
-
John, Do you have a cold well on the farm? If so I would run to waste, And just use the waste for watering your plants.
you would need a pressure regulator to reduce the water flow so it could cool
the YH, too much pressure will be too fast flow to remove heat.
you need the correct delta-T when applying this cooling technique.
too many years in the marine propulsion and power production industry.
thats why i have my plan of only 5-7psi thru the 15 pass cooler.
it might take more/less and that would be simple to adjust with the inline pump
i'm using, 12vdc also just like the cooling fan.
for a closed system like this, you need some sort of pressure relief.....
i have that as well in my plan.
and remember, i'm only topping off rifle cylinders not filling bottles.
when i have it working my way, i will let you folks know.
thanks..... ;)
BTW, my YH arrived safe and sound about 20min ago...i gotta go play now !! 8)

Why do you have a bad feeling about this seller. I checked the feedback for them on the compressors they have sold and all were very happy buyers.
If it does not show up the funds will be refunded. I used PayPal credit so not worried myself. Have not been burned yet in 11 years on eBay. Only had three disputes and all resulted in my favor.
Mike
-
Why do you have a bad feeling about this seller.
I'm gonna guess because in all their 97 transaction history there are only 2 compressor transactions (both positive, both best offer taken on a $315 listing BTW), 1 other transaction above$100 and the rest were ~1 euro-ish transactions.
I do agree that Ebay has you covered either way, but it sure seemed to good to be true to me (though honestly, I feel these compressors will be $200 shipped in the next six months with the price arc the hand pumps took once China flooded Ebay with them) or they made a mistake of only one button off during a price change and suddenly we had the deal of the century!! ;D ;D ;D
-
just tested my new YH, it took 46 seconds to fill my mrod from 1600 to 3000psi
it had to fill all the lines, the black and the gold filters.
max temp was 56.7C it was 30.2C in my barn when i tested.
i believe i can do better with my cooling system i've talked about earlier ..........
maybe not ;)

Yup, to good to be true. Just received this from Ebay...
"Dear friend,
Have a nice day!
I want to apologize for the mistake that I made. I accidentally reversed the number of 2 and 3 when I modified the selling price. Its actual price should be USD326.5. I'm so sorry for the inconvenience that it caused.
My friend, the price difference is kind of big that I might not be able to bear it myself. Could you please help me on this? I can offer a discount, and you just need to pay another USD70.
I'm so sorry for the trouble. Hope you could undestand.
Best Regards,
Elly"
I told him to refund me, not really in the mood to play bait and switch scams. Bizill called this one...probably a good guy to gamble with if he's on your side!
-
Max,
Another member got the same response, posted in bargain gate.
I wouldn't give him a break, let PayPal and Ebay know what's going RFN...
-
PayPal and Ebay don't just protect the Buyer Only :o They also protect the seller as well, Or they would not be in business. It works both ways, It's a 2 way street. I never received and email back, When I had a Question about the Item when the price alert was Just Posted, So I passed. If it looks to good to be True, It usually Is ::) This happens a lot at the Wal-Mart site as well, Make a reasonable offer you might still save 20 bucks, ;) Jaa
-
I got the same eBay message from the seller saying they mistakenly reversed the 2 and the 3 so it should have been 326 not 236 and if I would pay another 70 bucks they will ship it. I will be calling eBay customer service tomorrow since I am not paying the additional 70 bucks. The seller should have proof read the listing first before approving the listing. It is not our fault they listed it at the wrong price. I have made the same mistake before and had to eat the difference, although it was not 100 bucks but still is not our faults and feel we should get what we paid for fair and square period.
For those that want to dispute it the eBay number for customer service is 1-866-540-3229. I will be calling in the am, it will be either they stand behind their listing or refund the cash.
I agree eBay protects the seller and buyer both but IMO this is not a issue that should be awarded to the seller since they obviously did not proof read the listing before posting it so their bad not ours and should stand. If they did not proof read first and caught it after there were sales on it they need to stand behind it and learn to proof read thourghly before posting.
That's two strikes for me so hope its does not come to a third time on trying to buy one of these compressors for a lower price. ??? :o >:( :'(

Mike, I can already see where this is going as I have the same mentality. Two "sweet deals" gone awry. It's gonna have you feeling tainted on the compressor itself when the sellers are bogus. Don't keep looking for that unicorn of a deal but take solace in the fact they can be had for around $300 which is still $77 cheaper than what I spent a couple short weeks ago.
I don't see these hitting the $250 mark, at least not for a year or more. And when it comes to Ebay, all you've gotta do is research what the sellers sell and read the customer feedback. It's quite telling. This particular seller may have made a mistake in his/her listing but what you really gotta look out for is hijacked sellers who've had their identity taken so the scammer can make a quick buck. And with ebay you'll find that 97% just ain't good enough to qualify as a "good merchant".
Get this compressor in your possession and enjoy it. You'll very quickly forgot the extra $50 you may have to spent on it. I've already forgotten the extra $70 I had to vs some of you newer buyers. It's all good in the hood when you ain'ts gots'ta pump.
-
Not trying to have a ^*%$#@ match here, But it sounds Like He was Upfront with You. Remember {He Contacted You} That's the {Difference!!} ::) And He a Admitted a Mistake was made in the listing. He didn't send you a coin did he?? Or try to rip you off by keeping your money. He in fact refunded your PayPal after asking if you would pay the difference ;) I put him on my Buy List as a good vendor, He's Honest and $326.00 shipped is a good price and, It's in the USA already! He's not out of line at all, And yes I just received my email from him and It does have a US 110 plug on it, Sooo I would say that's good communication. Good Luck on your endeavor. Looks like he has 7 in stock http://www.ebay.com/itm/232392135157?ul_noapp=true (http://www.ebay.com/itm/232392135157?ul_noapp=true)

I just did a search of Ebay there are {7 vendors} out of ALL the listings, That have the Young Heng compressors located in the US ready for shipment, His price is the Lowest at $326.50 the next is $329.50 and the rest at $345.00 https://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=30MPa%20PCP%20Electric%20High%20Pressure%20System%20Air%20Compressor%20Pump%20220 (https://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=30MPa%20PCP%20Electric%20High%20Pressure%20System%20Air%20Compressor%20Pump%20220)
-
$70 + the $236 already paid is $306 delivered from here in the US. Not $326. I would be upset but I would also have to make a decision. These compressors are not without issues. I know where 2 of the Tuxing brand are sitting on a shelf burned up. If you are successful in forcing the seller to ship at the price you paid, I would think future customer service will be something less than a pleasant experience.
-
Mike,
I am curious on how Ebay decides to deal with the price error issue. I think that either the seller should honor the price or refund the money. Asking for extra money after auction end is definitely not fair and I am almost positive against Ebay rules.

Ive had this happen.. I bought a paintball gun for dirt cheap.. a few minutes later, I got an email saying it was " supposed to be an auction , and I bought the item at the lowest bid "
Well guess what , had I known that id have never bid.. Needless to say the guy said please include 5 extra dollars to cover shipping.. I said " no problem " and he sent the gun well below cost.
The fact is , with the compressors , it seems like it was lure tactic.. Not a mistake.. They figure once you are on the hook , you will pay the 70 shipping.. I agree with Mike.

If it all pans out, $306 is a lot better than I paid a little over month ago. Even though I paid a lot more for the compressor and have been using it all the time without any problems, I'm still very happy with it and have no complaints. I did order spare part, knowing that in time, It will break. I do have a lot of faith in it because I will not let it overheat. Bob
-
My main concern is motor longevity, as that would be expensive to replace. These are too new and unproven to pay premium prices for IMO, I measure durability in years not months. That being said, I was willing to be a guinee pig at $236.

He wouldn't be paying his ebay fee's as much this way. Seller wins. Ebay and customer lose.
-
I did some research on EBay seller rules, basically when they pull something like this the get a "defect" point on their EBay account. When they reach enough points, they can no longer sell anything under that account. They still have to pay the listing fee, so it's quite idiotic to do intentionally. You can technically sue for breech of contract, which is a joke. Apparently this is quite common on EBay now, the old " lure and cancel" scheme.
-
Well I have read all of yours comments as to what you think happened and will or will not come from this and myself feel it is a bait and switch scheme so once hooked they real you in and I am not biting. I am watching a few other sellers right now that are within 6 dollars or so of the jacked up price on this compressor. If I was willing to pay that price for one I would already have one and do have a shoebox so am in no hurry to have a Yong Heng compressor.
Not sure why it is stated that the seller will not be paying his fees so seller wins and eBay and customer loses. Seller may not pay as much in fees but eBay still gets paid and buyer wins and for me is as it should be. Its called live and learn from your mistakes just as I have had to do all my life. Some very costly mistakes.
Yes he contacted me but I do not see it as upfront but rather a ploy to get more money from the buyer. Yes I am very untrusting and wary of sellers that do this sort of thing. I know that when I am selling something on a forum or eBay I proof read two and three time before I post it so I am not put in this type of situation. Maybe I am more anal or thorough than others but life and my work ethic has made me this way since I have peoples lives in my hands every day I worked on their cars or bikes. I have had to eat hundreds of dollars over my working career from getting in to big of a hurry and failing to not fix correctly the first time. Fortunately no one has ever been hurt due to my mistakes. I live by the motto, "If you do not have the time to do it right the first time where will you find the time to do it right the second time when it is for free". Yes I still do make mistakes in life just like everyone but do not blame others for my mistakes or expect them to pay for them.
At this point I have 30 days to decide which route I will take so I am in no hurry to decide.
Mike
-
It could have been an honest oversight on the seller's part. What I was alluding to with the seller winning is depending on the ebay fee structure..(lots of branches in that tree), if ebay gets a percentage of the total sale price, then they'd get less off the seller if that "under the table" stuff goes on. Not like I care about Ebay or their profits, but just saying...the savings aren't intended to be offered to the buyer and Ebay loses a small amount of profit and the seller gets to pocket the difference of the smaller fee.
-
Bottom line....
The seller listed several compressors on an online site for a stated price. And sold several at this price over a period of time. Then the seller backed out. How many would you need to take money for before you realized it was the wrong price? For me? The first one.... not several. Something stinks..... really bad.

Thanks Bill, My point exactly. It may have been an honest mistake by the seller but that's on them the seller not the buyer.
As far as eBay not getting the full fee from the sale at the jacked up price that is incorrect since the extra will still be paid thru PayPal and attached to the item number that was purchased so eBay wins and the seller wins but the buyer loses. That's the way I see it. Do not penalize the buyer for the sellers mistakes. Live and learn just like the rest of us have to do.
Mike
-
Wouldn't the seller have to invoice you the remainder, outside the auction???
Yes, that's been my point since I saw the posted auction link...something wasn't right and it was clear to see if you trust your Spidey-senses.
You're good to go as you have a SB but everyone should beware posting deals too good to be true as it's gonna break someone's heart after getting their hopes up. I've already seen some tears flow in this thread alone... ;D
-
Speaking of tears flowing, seems there's a hit squad out there trying to defame these "cheap" compressors over at AGN. I have to wonder sometimes if one of the members posting is not the "competition".
-
Well I have thought long and hard on this and everyone is entitled to their opinions as that's their right as it is mine. The way I see it is this is a classic example of just why this country is in the wet poor shape it is because no one is willing to accept the blame for their actions or be accountable for their mistakes in life and business. I am not willing to bear the additional cost that has been requested by the seller nor do I think I should have to since it is no fault of my own that the item was priced incorrectly. If we continue to coddle and excuse poor performance and inattention to detail under the guise of it was a harmless mistake we remain stagnant and allow our own failure to perpetuate.
It is time that when a mistake is made that those responsible are held accountable for it and not allowed to pass the buck for their own lack of attention to detail. Before that listing should have been posted it should have been previewed with the function on the eBay add template to insure it was correct in all areas, not my fault it was not correct.
I have contacted the seller and explained the fact that an incorrect price is not my fault and I will not bear the cost for their mistake. If I do not see a shipping notice with tracking number with in 24 hours I will be opening a dispute case with eBay and they can decide how it will be handled from there.
This may seem wrong to some but if it was posted correctly the First Time I would not have to be dealing with it now. My time and sanity are far more valuable to me than allowing someone else's error to impact my life and time.

I have posted this response in the original bargain gate thread "Ebay compressor for 236.00 dollars" to let those that on this thread see how it progresses, For how the seller was going to collect the additional 70 dollars I have no clue as I will not pay it. Here is my last post in the other gate till I have more info tomorrow evening.
If you read my last post I have sent the seller a message stating I expect the item I purchased to be sent to me to me for the price on the listing. I can tell you from experience that eBay expects you to try to work things out with the other party first before starting a dispute. They have the ability to see all transactions and messages sent between both parties. As far as how the seller choose to collect the additional 70 dollars I have no clue since I refuse to pay it since it is a form of extortion. I do not bother with eBay online procedure to file a dispute since this is not my first rodeo and have the phone number for customer service written down for times such as this, I would rather speak to a live person than send an email for situation lime this. 1-866-540-3229
I will know more tomorrow after 6 pm when 24 hours since I sent the message to the seller has passed and I either receive a reply stating the item has shipped and have a tracking number to prove it. If no response then its a call to eBay and the ball gets rolling.
I am sorry for posting this supposedly bargain in that gate now that it has turned out to be a scam but then had no way of knowing that ahead of time. If you use the system that eBay has in place then you are protected in cases like this especially when PayPal credit is used since they can remove the funds from the sellers account at will.

I agree Mike, no-one is held accountable for their actions any more. I blame the stupid hippie liberals in California for most of it. I can't wait to get out of here.
-
The seller is a moron. So seek out a good deal where the bottom won't fall through and enjoy. I thought you were trying to defend the deal and/or seller so I was attempting to enable you to do so for some reason unbeknownst to me. Screw 'em. Hold their feet to the fire if you are able. Just don't waste too much time trying to find that ultimate deal that will never come to be. And you've been mentioning your past deal that fell through over and over and will do the same with this one. I'd much rather you just get a compressor at a decent price and join the conversation as to upgrades and other inquiries and share in everyone's elation.
-
Well I have read everyone comments on this compressor issue and understand all the views both positive and negative. The only reason I have not just bought one at the regular price is I have a shoebox so am in no hurry to pay the full price for one as it is now.
I would like to report that my diligence and standing by my principles that it was not my fault resulted in the sale being completed to my satisfaction for 236.00. The compressor is shipping by UPS right now and should be here in 5 days. The seller took responsibility for the mistake in the price and honored the sale. They left me positive feedback and the same will be left for them.
So I will be the proud owner of a Yong Heng compressor in the near future so sometimes you just have to stand your ground when its the right thing to do.

Already got the gold filter with the 13x sieve in it so just have to add some activated charcoal to it .
Yippee Ky Yay.

Well I have read everyone comments on this compressor issue and understand all the views both positive and negative. The only reason I have not just bought one at the regular price is I have a shoebox so am in no hurry to pay the full price for one as it is now.
I would like to report that my diligence and standing by my principles that it was not my fault resulted in the sale being completed to my satisfaction for 236.00. The compressor is shipping by UPS right now and should be here in 5 days. The seller took responsibility for the mistake in the price and honored the sale. They left me positive feedback and the same will be left for them.
So I will be the proud owner of a Yong Heng compressor in the near future so sometimes you just have to stand your ground when its the right thing to do.
Mike
I'll give ya $250 ;D
Good for you congrats.

I will inform everyone when it arrives, Tracking shows Tuesday the 29th by UPS for 47 pound package. Now need oil and water flow meter plus activated charcoal. Then figure out the setup and mounting the gold filter and water supply container. So much to do so little time. 8)

47 lbs! That will be a whole lot of them little coins :P

Guys, my ebay compressor rolled in the other day and I was able to get it fired up. I wanted to fill my Air Venturi bottle from 2500 to 4500 psi. I have the same set up as most of you, gold filter, used 5 gallons of water with 1 gallon ice jug thrown in there. First went to 3000 psi, had a leak in the gold filter (loose connection, my fault). Tried again and all good, so let it continue in an attempt to get to 4500 psi. It really struggled to get there. I was surprised. It gets to 3000 psi in 60 seconds or so, but took the better of 5 min to get to 4500 psi and after 4000 psi, you can hear it struggling. I watched the head temp and it only got to 57 C when I shut it down just shy of the 4500. It was still steadily creeping up, so no steady state was achieved. The sound of the compressor changed at 4000 psi, it made me nervous as I do have a little experience testing bearing surfaces and have heard the sound of transfer particles being made and growing in size and it sounded oddly similar under those higher pressures. I might just use this to top off guns at 3000 and if needed, I can swing by the shop for longer hunting trips when I want the extra air.
Update on my original purchase, ebay wants to wait another 5 days to hear from the supplier. ugggh anyone know how to get them to bypass this? I just want my $ back.
Thanks again for everyone's input. Will post updates as needed.
-
Thanks for the heads up Conrad, I've heard elsewhere that the motors sound too overdriven to last very long. I've tried several times for one of these compressors and failed, maybe it's a sign.
-
Well I decided to gamble on one for $228: http://www.ebay.com/itm/182678511464 (http://www.ebay.com/itm/182678511464)
Seller is questionable but has several of these in their sales history and of course, Ebay buyer protection.
Now to order the filter materials....
-
LOL.... here we go again..
-
LOL.... here we go again..
I was thinking the same thing when I posted it Bill... LOL This is coming from China, so I may post my really nice Chinese coin when it shows up (buyer has sold 12 of these in a previous listing with several positive feedback, hopefully I can also post positive feedback!)
Either way, I'm gathering the filter materials, oil etc because at some point in the next year I will have one of these. I really want to up the power on a couple rifles and only having a 3K scuba as an air source is too much of a hassle factor to have some hungry guns.
-
Tell you what.....
If this plays out, I'm in for one at that price. We go to my sister's to shoot and it would be easier to lug along than 100 cf scuba tank. I would fill guns with it only.
-
Under $250 was my magic number.. I have a gut feeling these are going to drop to ~$250ish everyday price and good deals in the $150 range at some point. There are too many on the market for it not to happen at some point.
If this goes through, I'm at $367 for compressor, a quart of Ultrachem 751, the gold filter, 10 replacement tampons and 3 lbs of the filter media to my door. I have plenty of the 1" pvc in the rack... ;D
-
My spare parts came in the other day. Piston ,rings ,seals. Going to do a topend rebuild even though compressor is still pumping away after it overheated. Will take photos of the rebuild😎
-
Great price! Looks like 6 positive reviews now specifically on this sellers pump. Hope it goes well!
-
Well, I wasn't really in the market for a compressor, however, after it took 150 pumps to fill the M-Rod yesterday, I was seriously reconsidering. Then, this morning I see this post, looked at the eBay listing, thought about it, procrastinated, waffled, rationalized and finally made an offer of $200 knowing it would probably be rejected and I'd be saved another purchase that would send me even further into the rabbit hole. Well, it was accepted! :o Dang! Now I feel obligated... I just hope I end up with a generator and not a Chinese coin!
-
Dang it Paul, I saw only 2 left so bought it at full price. You are a lucky man👍🏻
-
Nice!!! I also didn't try offering since I figured they would just be sold it almost instantly. Lol. It was under my target, that was good enough for me. If it actually shows up, I'll lb happy.
-
now there is 10 available @ $228 or best offer....... ???
notice it dont say "yong heng" on it and it ships "EPACKET".....thats
the same thing i got stuffed with :o
i hope yall do much better than i did. but at least ebay protection is there. 8)
-
Whoop Whoop Whoop !! Warning Will Robinson.... EPacket.... gentlemen... cancel those orders.... A compressor will NOT fit in an EPacket.
-
The ad is barely readable in engrish, the e-packet thing doesn't bother me unless I see that's what shipped. I'm happy to be an ongoing part of Yong gate...
-
the ad now is clearly in english......and it says its shipped Epacket !!
i've been there, good luck
-
This morning he had one left.... now he has ten.
Man, I wish you all the best of luck.... at the end of the day you have ebay and hopefully PayPal to back you.
And who knows.... those coins could be worth something someday.
-
Dang, hopefully it isn't epacket. Here is the weight limit :
"Additionally, the package cannot weigh more than 4.4 lbs (2 kg) to qualify for ePacket delivery and the merchandise being shipped cannot exceed $400 in value."
-

Yeah I'm not gonna sweat it too much. If a Chinese coin shows up, I'll file a claim with eBay.
Plus, "cancel an eBay order" isn't an option. Lol

Don't do it Ken! I promise you it is a can of worms.
-
Well I've been following all 50+ pages of this and after seeing the $228.12 unit that will be shipping from China I made a $190 offer and my offer was almost immediately Declined. I then decided what the heck and made a $200 offer and it was again it got an immediate reply saying Accepted this time.
So I wonder how many coins I'm going to get!!! Having E Bay and PayPal backing me I feel pretty good.
OK now I need some help as I do not really want to go through 50+ pages to find all the extras I am going to need. Things like the correct oil, the gold filter and the filter material I will need for it plus the O ring size. Links to those would be a huge help, Thanks beforehand!
Any pointers would also be helpful.
Norm
-
I wouldn't buy any of those extras until it actually shows up and is a compressor! :o. I'm in the same boat, I'll play the wait and see game and see what happens. Who knows, maybe the e-packet is a typo. Anyone care to reach out to the seller and ask?
-
I ordered all my filter stuff and oil because either way I'm going to have one of these soon enough, if it isn't real this time, it will be eventually (and possibly a larger compressor if I'm patient enough, which will still require a high-side filter).
I do feel better that Norm had an offer declined. The e-packet thing is a little sketchy, as is magically having an extra 10 compressors to put on the listing. LOL. Time will tell, I've had excellent luck with Ebay standing by the buyer if something goes sideways, otherwise I probably wouldn't gamble.
-
i contacted the seller and asked.....'how can you ship this ePacket when
max allowable weight is only 4.4lbs' ??
i'm waiting a response...... ???
-
I wonder if there is a market to sell off an ebay account with a few decent transactions and history in a few higher priced items? I mean, this seller has sold a few of these in previous listings with positive feedback, had 8 left from a previous sale and originally had 8 of these in this sale (which all makes sense to me). I wonder why they would suddenly try to scam ebay for a few of these? I guess if you got away with it it'd be an easy way to make a couple grand. Not sure what Ebay's recourse is for a seller like this after they refund all buyers money?
BTW Max, I like " Yong-Gate 2017".... It has a nice ring to it.
Edit:
There is this note in the listing:
Notes for delivery:
1. The order within 2KG to United States will all be shipped by ePacket from China. Most of clients from USA will get the items within 15 days.If the order over 2KG to United States, we will ship you by Fedex/DHL/UPS/TNT or divide into two or three parcels by ePacket from China.Which shipping way we will ship depend on which is cheaper for us. Most of Delivery time is 7-15 days.
-
No plans of ordering from this seller, all though, that corndog waffle maker looks awesome!!!! ;D
I did notice this though, cut and paste from one of this sellers adds.
"1. The order within 2KG to United States will all be shipped by ePacket from China.

Good luck fellas, I hope all of you get a compressor 8)
Edit:
Note to self, no pee breaks when posting....
-
That sounds better!
-
I would look at the shipping info very close once you get a tracking number to see what the weight of the packet is, if its lower than 40 plus pounds I would be ready to contact eBay to start a dispute. As Bill stated an E-packet is not big enough to fit a compressor in it so be cautious when you get shipping number.
Mike
-
...that corndog waffle maker looks awesome!!!! ;D
I saw that! I wish I had seen it before I made my offer, I'd of offered full price if he threw in the corn dog waffle maker!
-
Actually, a waffle sounds pretty good.... keep the hot dog.

Mike
Mike, did you get a tracking number on your ultra cheap scam that didn't work out? Does epacket typically have a listing for weight?
Actually NM. We already know if it shows as an epacket shipment that it's not a compressor. OR, it's 11 different packages all with pieces of an "assemble your own" air compressor! ;D ;D ;D
-
I hope John ( gendoc) hears back soon and lets us know what is said by the seller about the E packet verbiage in the listing.

This is starting to sound too good to be true! Dang! And, I was already mentally preparing myself to fully engage via eBay and PayPal! LOL!
I know he already left me positive feedback, thanked me for my support, and said he looked forward to dealing with me again! He very well may be the real deal!
-
I truly hope all my instincts are wrong... You guys would be getting an awesome deal on these.

I'd personally rather spend the money on a gun instead, the dive shop is just too handy and inexpensive for the time being. When the hydro dates run out on my tanks in Dec 2019 is when I'll be looking into a compressor and no telling what's going to be available by then.
-
I would to like see the verbiage "compressor " in the return message that John got from his question about shipping. Hope for the best for all that bought compressors.
Mike

So, does anyone have a list of parts needed and a simple how-to on getting these things set up and running? If I understand correctly, at a minimum, we will need oil, a bucket and some sort of separator. Any recommendations on oil or the separator? I'm assuming any bucket will work for the cooling water...

You know, living on the Gulf Coast, you'd think there would be an abundance of inexpensive, convenient dive shops near by. But, the closest one is 10 miles away, at the foot of a busy bridge, on the opposite side of the road and they want $10 to fill my 90ci tank! I only get 7 Mrod fills from that tank, so in 20 tank fills I've paid for the compressor!

I love my local dive shop... but they are 45 minutes away. Tolerable, but I have a hankering for more power and only having a 3K scuba for a source is a limiting factor for me. Honestly, this and better glass are my only 2 wants right now.... next will be a .25 cal something or another... LOL

What's crazy is the guy that owns the dive shop said that when he fills a guppy tank or another tank that small he feels guilty charging $3 on them. Airsoft guns are really popular in this area and he's the closest here in town and luckily for me he's right on my side of town only a 10 minute drive for me. I pay $5 for the 88cf.
There are a lot of things to consider about the people owning the dive shops and Terry the owner where I go really lucked out when he got his compressor from a local fire department at a cost that's 1/10th the cost of a new one.

Let me see what i can do about that... 8)
-
Thanks Wayne. I guess I need to visit a couple fire stations and see if they can fill it for me. I just feel guilty bothering those guys for something like this! I feel $3 - $5 a fill for this size tank would be fair. $10 is a bit steep!
-
My dive shop was an 80 mile round trip and Mr. George was a great guy to talk with. He is 88 years old and was still diving and teaching classes. He will be closing up shop this month. I would call him and he would make an appointment for me to come at my convenience and we would chat for a couple hours each visit. His experiences were story book material. His shop was virtually packed with artifacts he had found throughout his diving life and he knew each one like it was yesterday. The $5 fills, $12 vis insp. and $24 hydro insp. were not even close to payment for the time I enjoyed spending there. I will sorely miss Mr. George. But, the thing is... the independence of being in control of your air supply is priceless. When I was installing the TSS and MDS in my SynRod I had to be mindful of how much air was left in my tank. Matter of fact.. I didn't have enough to completely fine tune it and I'm not physically able to hand pump to 3k with a torn rotator cuff and wouldn't want to if I was.
-
Oh I hear ya Bill, the only time I use a hand pump now is out in the field and that's not that often. The first time I go out there with my Dominator I'll bring along my pump though :D

Let us know.

I've sent 2 messages so far with no response.
If you scroll through the feedback there are four positive feedbacks in a row on the compressor. If you click on "view item" there is a banner that reads to the effect of "sale ended due to broken or lost item" on all 4 of them. What the heck does that mean?

It just means more red flags and weirdness Bill. Lol. I've scrutinized every possible angle on this and I think it was Packard that pointed out they have at least one sale on another item that listed as free shipping and then hit up the buyer for shipping after the sale.
I think if there is a $)((# in the punch bowl, that will be it. Last I checked I think there was 29 sold on this listing. That is an incredible amount of sales to take on if it's a scam. I won't be leaving neutral feedback if he hits me up for shipping costs also. Lol. I don't think I'm the only one either.

Not sure about the "lost or broken " reason for the seller to end the listing. I agree it is getting fishier by the day.
Time will tell.
Mike
-
Yeah, I really don't mean to keep running this in and out but, they have a lot of stuff in their store and they seem to be selling with good results. You would also think that Ebay would have acted by now if there were flies in the ointment. I've had the dam thing in my cart 4 times and something just won't let my finger push the button. I know I have backup through PayPal and Ebay but I also know I have a pretty low threshold of tolerance. I don't want to be labeled as an internet terrorist n junk. You never know where those J. Edgar Hoover wannabes are lurking.
-
well , it seems like they try that " free shipping" thing pretty often.. someone in the feedback mentioned being asked for additional funds.BUT
THIE FEEDBACK LOOKS LEGIT.. THEY HAVE DELIVERED COMPRESSORS.. the previous sales say 309.00 shipped. interesting

Mine will be here tomorrow and is signature required from UPS by end of the day.

Yeah... I thought it was... pretty good feeling you'll get yours.

If its coins them I will have enough targets for the rest of my life. ??? ;)

Mike may actually get lucky. The rest of you from the most recent "deal", doubtful.
Regarding the "positive feedback" from other buyers on the same item, they have a network of friends make faux purchases, go through the whole process of paying and what not and then leave feedback for a future scam. It's hard for one person to have multiple ebay accounts as they tie it to a bank account, I believe but there are ways. But most likely it's a network of family or friends setting up false feedback and then scam new buyers in some way.
It's easy for the seller to claim they made a mistake in the listing, as it does actually happen and is easily overlooked. These scammers on ebay are easy to spot if you're used to ebay and are a pessimist such as myself. Sure, you can get your money back but who wants to wait as your money is tied up in a rotten deal?
Buyer beware fellas. I don't like seeing my fellow hobbyists getting taken.

Just curious... do you have documented proof of this or are you speculating? I agree all my senses say RUN !! But, I remain hopeful for my fellow members.
-
No proof but no need to speculate either. It happens. It's not hard to figure out ways around any system. Not saying this is happening, but it's easily feasible. Perhaps this deal will be another bait 'n switch. Let's see how this one plays out too. Doesn't seem to hard to figure. This one is sloppy too with "e-packet"...
Also, what's to stop the sellers from trying to invoice the buyer outside of ebay's framework? And persons who don't know better may end up falling for the 'ole "money gram/western union" &^^& and not be protected by Paypal. *(&^, even on Aliexpress (Chinese Ebay) they did just that to me but it was "legitamate" and wasn't a scam and that was obvious.
I'm not sure how these yahoo's get away even temporarily with money. When I was a wee lad and new to Ebay and the internet in general I was buying some RDram for my Dell computer which was expensive as heck for "bleeding edge" tech and won a Dutch Auction where the price was too good to be true. I was faced with breaking the rules but something told me don't pay and I could have gotten in trouble for non-payment with Ebay but took the risk. Paid off as a week later all other Dutch Auction winners started emailing me and each other to ask if anyone received the items? Luckily I ducked out of that one. But not everyone is as untrusting and paranoid as I am. So many innocent folk get taken all the time in so many ways.
-
Well yeah.... if you go outside of Ebay to pay them you'll most likely get burned. I would report that activity pronto.
-
I understand that scammers take on all forms of clever ways to deceive the buyers but don't really see sellers on eBay enlisting friends and family to post fake sales and feedback to scam a few hundreds of dollars from the unsuspecting. The eBay/PayPal protection system is just way to aggressive to allow it to be completed and the funds kept from being refunded back to the buyers of scammed listing. Then after three disputes that are determined to be the sellers fault the sellers account is frozen from further listings until they rectify the situation or are banned for life.
To be a seller or buyer on eBay now I believe you have to have a verified bank account that eBay/PayPal has access to for being able to withdraw or add funds to as deemed by them to close a dispute case. So it would be very difficult to pull of one scam on a buyer much less several buyers without being reported to eBay and have them intervene to rectify the situation. I just do not see it being very profitable for it to be occurring over a few hundred dollars. Now on a much bigger scale monetary wise I can see it being attempted but still there are much easier ways to scam people that are harder to prove or recover the losses.

-
I've never sold anything on Ebay so I don't have a clue as to how the money flows. Ebay gets a cut somehow.
-
I'm one of the buyers and my senses said run too, to be honest I'll be more surprised if a compressor actually shows up at my door than if I have to file a claim with eBay!
That being said, I would like to have one before next summer, so I have time to gamble on a few unicorn deals.
-

They actually bill you after the sale Bill. At least that's how it goes with any of my sales. Might be different in other countries.
-
Ebay gets a percentage of the sale price less shipping and is linked to a bank account so they can collect their fees from said account if you do not pay the fees first. So they collect their fee regardless if the funds are in your PayPal account or not. I am not sure how they proceed if the funds are not in the linked account but would suspect your eBay account will be locked until the fees are paid and repeated occurrences will get you banned for life.
They are going to get their money no matter what.

This, in my opinion, is the only attitude to take into this deal. Expect the worse and hope for the best. Be silly to get all pissy if it goes bad. All the warnings were already there. Kinda like being told to evacuate and choosing to stay.
-
I may have already told this story but it fits here..
I ordered some O-rings on Amazon for $10. I got an e-mail that the seller had not shipped within Amazon's required time frame and I could contact the seller at my choosing. I declined and cancelled the order. The money has never been deducted from the account I paid out of. I just checked status on the order and it still shows as "ordered" with a delivery date of 9/1/17. Amazon does not withdraw money from your account until they receive shipping confirmation from the seller that can be tracked. That's not to say the package don't contain a lump of coal.

I just messaged him and asked when I can expect to see a shipping notification and when should I expect it to arrive. Purchased Aug 27, funds already pulled from account, compressor still sitting in China! Ida thunk it would have shipped by now...
-
I would to like see the verbiage "compressor " in the return message that John got from his question about shipping. Hope for the best for all that bought compressors.
Mike
Let me see what i can do about that... 8)
Go get them John. I have faith that you will get the compressor added into a message from them if asked directly.
Let us know.
Mike
Response from him this morning was....
"Thank you for ordering. Sorry for your wait and let us know if you need anything else"
Sounds like he changed the subject from my request of.....what are you shipping fedex ?
Its getting good now !!!
-
I predict that in the next 1 to 8 weeks there will be no speculation and we will know exactly what the jig was. ;D

Yea that is an evasive answer indeed, does make me wonder if the seller is on the up and up. So much for my faith for the seller being forthcoming with a reassuring response.
You should know more when and if you get a tracking number that will show the weight of the package. Should be close to 47 pounds give or take if it is in fact a compressor.
Hope it works out.
Mine is on the UPS delivery truck today so should have it by end of the day.
Mike

The one question I have right now, which perplexes me even more is, why leave feedback for buyers if it's a scam?
What could possibly be the end game there? Buy them time? Sell more in the 5ish days they said it would take to start shipping them? Last I checked they were at 32 sold, that's $7300. Not a bad haul if you can get away with it without Ebay catching up.
-
Nobody is going to buy from a seller when they see the price is too good to be true unless they see prior sales....hence, the scam.
-

Yeah, but I mean he has left positive feedback for me (and other buyers) for this particular listing.... I understand him having other "successful sales" for this item assisting in his scam, I just don't see why he'd even bother to leave me feedback.
(http://i.imgur.com/ODAh3fq.jpg)
I think we need to get Columbo on the case! ;D
-
I'll be tickled pink when the first one shows up.... and I didn't even order one.
-
You can set up the seller account to automatically leave feedback with the message for a sale. It may be that's how they have it setup to complete the affect to buy time.
It does seem counterintuitive but the game has evolved a lot over time.
I will also be glad when the first one from this seller gets delivered on time and be a compressor.
Mike
-
I sent a message asking him if he is going to supply a tracking number when my compressor ships.... I am guessing I'll get a fairly generic response like John was getting.
-
If he don't respond with a generic answer I'm gonna message and ask for his home phone and address.

I received the exact same feedback as Kevin, so more than likely it is an automated response!
-
Since this is such a hot topic, those that were coined, what process did you follow to get your money back from Ebay? Was it fairly painless?
Several of us may need this information shortly! LOL.
Conrad? Gendoc? BandG?
-
Ebay and PayPal both have a claim process.
-
I'll be tickled as well, but I don't think we're at that price-point just yet. Could be rapidly approaching, though.
If it's a scam, the purpose would be to show activity on their part to keep the scam alive and trapping as many folk as possible. IF it's a scam.
-
EBay owns PayPal or vice versus so basically one in the same and is why they have access to your funds when necessary.

1. The order within 2KG to United States will all be shipped by ePacket from China. Most of clients from USA will get the items within 15 days.If the order over 2KG to United States, we will ship you by Fedex/DHL/UPS/TNT or divide into two or three parcels by ePacket from China.Which shipping way we will ship depend on which is cheaper for us. Most of Delivery time is 7-15 days.
Heavy items shipped from China will come out of someone's pocket. I agree with the poster in the bargain gate. Expect another, "please send more money for shipping" email..

I guess if you're retired. I wouldn't have time to deal with that. Sorta would be nice if only SUCCESSFUL "deals" were posted in the Bargain Gate.
-

who's retired... i'm on my second tour ;)

Anyone retired or doing well off with money. I'm neither and have hobbies and kids to feed so no time to waste with a potential scam. Lots of folk here sure love to gamble. See ya in Vegas. :P
-

Aww c'mon.... don't do that...
All had the option to buy or not and all had the same info to base the decision on.

I feel ya, but there seem to be many "apologists" or even "enablers" of scammers. I'll say it again, I do hate and would hate to see my fellow hobbyists get scammed. Bargain Gate should be reserved for deals that can be readily duplicated.

On a sort of related note, the guy selling the refurbished Molecular Beads (http://www.ebay.com/itm/3-lbs-Molecular-Zeolite-Beads-Type-13X/311845008955?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D46829377034b434183fcd8ae635245b0%26pid%3D100675%26rk%3D2%26rkt%3D15%26sd%3D222243982155&_trksid=p2481888.c100675.m4236&_trkparms=pageci%253A0da090d6-8d0c-11e7-b8e1-74dbd1808fc1%257Cparentrq%253A302db94515e0abc66c006de4fffb1fde%257Ciid%253A1) linked to in the "Chinese High Side Filter Hack (https://www.gatewaytoairguns.org/GTA/index.php?topic=126349.0)" is actually located in Spring, Texas. Which is currently under several feet of water. I hope he and his family are safe!

If a bargain was posted in the bargain gate only after the deal was successfully completed... the bargain would be long gone..... you know that.

I don't honestly think the fellow that posted it in the bargain gate was being malicious (and I'm assuming you don't either :o ). I posted it here first (https://www.gatewaytoairguns.org/GTA/index.php?topic=123440.msg1302709#msg1302709)(with a warning that the seller was potentially suspect) because I felt like the group following this thread knows the risks. I also know the risks, I also don't have much time to mess with refunds, but I do have lots of time before I feel like I "need" a compressor.

I agree with you Bizill! A "deal" on ebay of all places from someone with hardly any sales offers at too good of a price to be true...I wouldn't post that "deal" up. Being we're all willing to buy cheaply made compressors vs the Bauer units and what not, we ought to be careful where we buy from. For all we know, Bizill, is that these things could be refurbs or factory rejects. Only way I'd want to post a deal is if a seller who is actually a legitimate distributor had a coupon code or Chinese New Year sale or something to that effect.
We've already encountered 2 bogus deals. One seller sends coins and another, what, asks for more money? Hot "dang", Bizill, you're such a card for pointing this out.

I know there was no malicious intent by the poster. But there are LOTS of people who read the forums and some don't even become members here that might see those deals and go on to get scammed, long after we who've been following these "deals" have learned the truth of the scam. We must all be cautious and watch each others' backs. I see we're now talking about a 3rd "deal" already in this thread alone. Sheesh.
-
And ONE proven scam that everyone got their money back on..... I think.
Sorry guys.... last post on the matter.
-
Once more for the record, I purchased for "Chon Electronics" on Aliexpress. No, i'm not pimpin' for them. Buy wherever you want but when I had questions and needed more "tampon" material for my pre-filter, they responded and took care of me. Should something go awry I know they'll be there to address my concerns. These Ebay fly-by-night guys will leave you high and dry. Just wish the compressors left the compressed air high and dry, then no need for hp filters! ;D
-
And ONE proven scam that everyone got their money back on..... I think.
Sorry guys.... last post on the matter.
Don't be mad, my brother from another mother, we were on the same page at first when you were even pointing toward a potential scam. That's what we're here for, to look out for one another, even if you end up getting flogged for it which I seem to be.
-
LOL... aw heck, ya got me..
We're still on the same page.... I just can't see making another brother feel guilty for pointing out a "potential" deal that, BTW, will be AWESOME!! if it pans out. Guess we'll wait and see.
-
Heck yeah, deal goes through I might be wanting an extra for spare parts or Christmas gift for a family member. I'd love to turn him on to PCP's.
-
I hear that... I'd take a beat down from Betty Lou to have one for roadtrips.

Well I did not post the eBay compressor deal in the bargain gate knowing that it could be a scam and I do not think any other person that posted did so either. There are so many chances to get scammed in todays world that it truly is buyer beware. If we waited to know its a real deal before posting it then all would lose out on the deals. Each has their own criteria as to what they are comfortable with when buying off the web so if you are not comfortable then do not buy its really that easy. The only reason I trust and buy off eBay is the fact that the buyer is protected for these situations very well.
Agreed that no one wants to have to deal with being scammed but unless you live in a cocoon chances are you will be scammed at least once in your lifetime. If it does not seem right to you then stay away it just that simple.
I just received my compressor about 30 minutes ago and have no inclination that the seller will not stand behind their product and be there if I need any supplies or assistance and if not then there are plenty more seller on the web to provide me with what I need or desire.
-
Well lookie there.... one scam debunked...
Is that the shipping box? Dang.... even that's better than a coin.
-
Buldawg, glad to see you got your compressor. That box/crate looks like the one mine got shipped in from the seller in China.
-
I hope we see a few more of those boxes soon.
-
Yep its a real stiff corrugated cardboard box that is secured with the flat nylon straps like heavy freight use to bundle packages in shipping. It would take a very good impact to get to the compressor since there is another 1 1/2" of Styrofoam inside the cardboard box as well.
Yippee Ky Yay no more all day filling tanks now and more time shooting .
Mike

Buldawg, glad to see you got your compressor. That box/crate looks like the one mine got shipped in from the seller in China.

Yep I hope so as well.

Now that I have the compressor I will be gathering the rest of the supplies to get it up and running tomorrow. Then just swap it for the shoebox setup and plumb the hoses and water bucket and away we go.

Do you have one on the way.

I do.
Ordered one of the $238 ones
Waiting to see how things work out
Give us a review when you have it all set up.

-
Yep I will take pics and give a run down of my setup as I go tomorrow. I have to decide how I am going to stand my gold filter up vertical and how to run lines so the lowest point will be the line out of the compressor so any moisture that collects at the bottom of the line will not flow into the compressor blocks or into the gold filter except when in use. By doing that I can unhook the quick connect at the lower end of the gold filter so any water accumulated drains out of line and filter end between each use. I will have a shutoff valve in the HPA line somewhere undecided as of yet to be able to just drain the compressor without bleeding the pressure off the entire high side when filling tanks.
It should be fine to restart the compressor so that it pressurizes the line before I open the system back up to allow filling as long as I let the line fill to a higher pressure than in the filter side before the shutoff is opened back up so there is no back flow of air or vapor.
Mike
-
Well his price went up to $260 with 38 sold.... At that price, I don't think anyone would have questioned if this was a scam or not, that's right in the sweet spot of good deal but not TOO good of a deal....
So perplexing..... would be crazy if we actually received compressors for $228. Not holding my breath yet, no tracking number to speak of (but it hasn't been 5 days for me either).
-
His response this morning again was
"The item will ship fedex"
He will not answer my question about....what will ship fedex ?
He will not commit to it !!
-
I wonder if this guy actually has the compressors in stock. Something tells me they do these "sales" to get a load of capital going then drive down the street and buy them cheaply in bulk. With almost 40 of these sold, you would think they would have started shipping by now. Just trying to keep my hopes up in Yong-gate 2017. I noticed a new thing on Paypal as well, there is now a $.25 charge to transfer a balance into your bank account. They must have an entire room of people who sit around and come up with ways to milk every cent from us.

I just got my money this morning. Well notification from ebay that I will be refunded, it hasn't actually hit my account yet, but I'm sure it will. It was painless, but took 2 weeks or so.
For the record, I was not coined... I was braceleted. LOL
-
Thanks Conrad. Item not as described claim through ebay itself?
I haven't done one of these in years, last time I had to make a claim like this I had to return the item to the seller on my dime with full tracking before I got a refund. I assume it's nothing like that now but I have to ask (for a friend of course ;D )

Well that's good news.... not good news that it happened... good news that it worked out. I sure hope Ebay takes action on the offender. Not sure what can be done... other than banning them from Ebay.... I'm sure the crafty little boogers will find a way back. We have an abundance of corruption right here in our own backyard, it should be a surprise that it's Worldwide. It's a darned shame when it happens to other people everyday.... It"s HUGE when it happens to us.
-

[/quote]
He got in on the first deal where the seller was asking for more money post-sale. He stood his ground and got his stuff shipped without shelling out more money. I think most others either cancelled or paid the "ransom".
-
Still something fishy going on though, of course there is this:
(http://i.imgur.com/8jTNieS.gif)
So topsee.666 is the one asking for more ransom money and topsee.666 is posting reviews for this compressor listed in the newest "deal" auction...
-
So the "new" seller is the old topse.6666 or they are affiliated and part of a "network" of folk or perhaps work for the same company or boss over there/here.
-
Unless Ebay knows this is somehow the same item and is allowing reviews from various sellers. Weird if so as there are only 6 reviews...am I missing something?
-
When I check reviews from other higher priced sellers the reviews show as sold by that seller for that particular auction.
-
Topsee 666
Is who scammed me the 1st time !!!
-
No, possible false alarm. Looked at a few other items not pertaining to compressors and in the reviews section there are reviews from multiple sellers.
-
Yeah, that's the "sold by" that you're looking at, the reviewer's name is on the left.
I tried to connect those dots before I plunked down my paypal but I didn't see a connection (other than those reviews are all for similar items, only one of which was actually sold by chenglong).
Good or bad, I can't wait to see how this works out. We've gotten so much mileage from this one listing alone! LOL.

Yah, you have to wait until the item arrives, then wait 3 business days for the seller to reply to the claim of "item didn't match description". Then another 5 business days while ebay investigates.

Sorry guys I was sick yesterday so could not get out to try to find the oil locally. I had no luck today after searching everywhere local. I just ordered a half gallon of the Chemlube 751 so will be waiting for it to arrive to fire it up and test it out. having it sent priority mail so hopefully will have it early next week.
If you need to file a dispute and prefer to do it over the phone as I would rather speak to a live person here is the phone number to call, when it ask for a security code just respond that there is no code and proceed as instructed for a live person. 1-866-540-3229.
Hope you all know something soon.

What version/models have people been buying and in 220 or 110?
[/quote
110 volt is the most common
-
It seems like it's been mostly hardcover models, not sure I've seen many , if any, of the simple models at least in the 110 versions I've seen here. The automatic and set pressure seem to be newer offerings in 110. I'm not sure I understand the difference between cutting off at 30mpa, and cutting off at 4500 psi?
-
I did get my money refunded by eBay to the PayPal account for the topsee666 original order. Not difficult but a bit more troublesome than it should be for a clear case of fraud. I ended up calling eBay customer service and had a single individual handle it quickly. Have a package that I missed yesterday and to be delivered today that should be the second one I ordered. Tuxing unit still running fine.
-
Got my shipping confirmation today, sure enough it says e-packet. Here we go again😀
-
Yep, I did too, same deal! I guess we'll see, nothing shows about weight yet...
-
me too..... ::)
-
Well I had to ask the seller:
How did you ship a 22kg compressor via e-packet? There is a 2kg max weight limit on e-packet.
You stated to me and several other people that these would be shipped via fedex international due to weight.
No status yet on any of the e-packet tracking sites, I'm curious if we all received the same tracking number even.... Mine ends in 6532CN, anyone else?
-
i give up asking this guy questions as he kept running around in circles
telling me it will be shipped fedex and not to worry ::)
my tracking ends in 7113CN.
ok thats 4 of us.....any more ???
from what i have read, there are 4-5 others on this forum that has purchased
this pump......speak up ::)

Kevin here in Kalamazoo where I'm at there's a really good spot for getting tanks filled. It's Days Divers scuba shop. Only about three miles from me. He does the big tanks for $5 and small for $3.

Wayne, I'm about 2.5 hours north of you. I love my scuba shop in Midland (Underwater Antics), just trying to reduce the hassle factor of the 90 mile round trip is all (and I'm going to up my air consumption once I have my own air source 8))

My tracking number ends in 6988CN. At least we're all getting something... Not sure what, yet...

coins, bracelets.....maybe this time we will get something we can use :o

I'm trying to figure out what they are gaining by operating this scam. Do they delay things long enough to get a cash pile together then close down the bank account associated with EBay? Poof, they're gone like a fart in the wind leaving EBay to pay all the refunds.
-
Ok, so the epacket thing pretty much insures this was a scam... and I couldn't help but think why would someone take the time to set up all those ebay listings, store etc only to be shamed/forced into closing as soon as all the @$%^ hits the fan.
I think (https://i.makeagif.com/media/5-29-2015/mr4JUU.gif), chenglong9842 is actually topse.6666 reincarnated. If you look at topse.6666 feedback (https://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback2&userid=topse.6666&&_trksid=p2047675.l2560&rt=nc&iid=182665900863&sspagename=VIP%3Afeedback&ftab=FeedbackAsSeller), you'll see he also had several positive feedback for these pumps as well as power inverters, exhaust tips, rotary waffle makers, Yanmar overhaul kits as well as gasket kits. Then in the end, when it all came raining down on several of these items being sold then receiving a plastic coin, magically topse.6666 has nothing for sale, but chenglong9842 suddenly has a great sale on the exact same pump as well as yanmar gasket kits, exhaust tips etc. (also with a few positive feedback for the exact same item).
Which (https://m.popkey.co/8a83e8/G058r.gif), leads me to believe that either the sellers start out legit to build up a few sales, then at some point either auction off their account so that the scumbags and vultures can pick over the bones with bogus sales, or they themselves make listings with zero intention of actually shipping the item.
Case in point, look at the description from topse.6666 (http://www.ebay.com/itm/High-Pressure-30MPa-Compressor-System-Rifle-PCP-Electric-Air-110V-or-220V-/182665900863?nma=true&si=Ns6QOMAv4sYsf26U97qfby4j31E%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557), compare that with the description from chenglong9842 (http://www.ebay.com/itm/Pump-Electric-High-Pressure-30MPa-Air-Compressor-System-Rifle-PCP-Air-Gun-New-/182678511464?epid=582839650&hash=item2a887cdf68:g:rZIAAOSwCU1YvQ3m), (you'll have to turn off adblocker to see them if you're using it).
For those that don't want to go to ebay, this is the exact same description from both sellers, one of which is a confirmed scammer:

good job ;)

One more thing, I have a theory that this will be the next "Great Ebay Pump Deal" seller: https://www.ebay.com/sch/lampseller/m.html?_trksid=p3692 (https://www.ebay.com/sch/lampseller/m.html?_trksid=p3692)
Exact same formula, currently 100% positive feedback.
Edit: Look at that, currently having a $268 sale on the same pump with epacket delivery (http://www.ebay.com/itm/High-Pressure-30MPa-Compressor-System-Rifle-PCP-Electric-Air-110V-or-220V-/182742708190?hash=item2a8c506fde:g:rZIAAOSwCU1YvQ3m). Same wording in the description, identical pictures.
So basically, forget these sellers with less than 100 feedback.... ?

Kevin- I don't know where you're located but "The Dive Shop" right off I-75 (Corunna Rd. exit/west side) in Flint is a great place for fills. Really nice people and they always fill my tanks while I wait. Dunno if that's any closer or even further away. ???

I have received the second YH compressor that I ordered after the first topse666 scam. It came from loveshoppingjxts seller from the $236 listing after some back and forth about the listing price error that I handled to my satisfaction. It is a YH compressor, it was very well packed, and it arrived relatively quickly. Bottom line, they are not all scams but certainly scams are out there.

It is a YH compressor, it was very well packed, and it arrived relatively quickly. Bottom line, they are not all scams but certainly scams are out there.
But the $236 was a mistake by the seller.... It appears that any sub $300 "deals" thus far are all scams or mistakes. Has anyone had one delivered for less than $300 on a legitimate listing? Not a mistake like the $236 fiasco, but a genuine" this is the price, thanks for your money, here is your compressor" deal?
I am going to buy one of these, and I will gladly pay the $330ish price tag next spring which is my time frame for when I really really want one. I have a reliable air source (that is 45 miles away) now, so that isn't the problem, I just want the freedom of my own air source. Until next spring, I might try another "deal" or 2, but I think the prices will eventually start edging down on these. Probably when our northern shooting season is winding down! ;)
I'm seriously considering just buying from this seller on Aliexpress (https://www.aliexpress.com/item/300BAR-30MPA-4500PSI-High-Pressure-Air-Pump-Electric-Air-Compressor-for-Pneumatic-Airgun-Scuba-Rifle-PCP/32815880523.html?spm=a2g0s.8937460.0.0.HNCXBm) if they are still around. They seem to have a decent price, plenty sold and 10 day delivery.

Off topic, my bad.

Well my tracking ends with 457189CN so as others have said we will be receiving something.
On another note this Topic is about E Bay Compressors and recently fill locations and now CF tanks post are popping up.
Please keep this related to E Bay Compressor and not drift into other topics.

I didn't want to take the chance and let this Ebay seller disappear with my money... so I filed a dispute through Ebay today around 6pm CST. by 7:30pm the seller didn't even put up a fight, and refunded my money!
yes, there is a chance this will ship, but it is risk at this point I don't want to take. in a 3 weeks we'll see if I made a wise decision to dispute this so quickly.
-
How did you file a dispute that quickly? It's telling me I have to wait until October 10. I seem to have been scammed as well.
-
Call eBay at 1-866-540-3229 instead of trying to file in the dispute center. Its easier to explain the situation over the phone than in messages.

Man... I really hope folks see the recent happenings with these things and stop ordering them from China. At least look for the signs that have been clearly pointed out in this and other related threads. It's all good if you're sitting on a pile of disposable cash but many folks aren't. And if we keep throwing money at these criminals, they are keep on taking it.
-
Yeah you're right Bill. I was thinking I'd play the game until spring and then plunk down the ~$330 on a known legit seller and get one. But if I do that, I'm just feeding the animal and that's not really fair to anyone.
What I haven't figured out is a surefire way to weed out the scammers, it can't just be on price alone (though we know if it appears to be too good of a deal it probably is). What are the other red flags?
- Feedback below 100?
- "More than 10 available"
- Priced well below the rest of the market?
- E-packet delivery
What else? Surely we can add to this list for the uninformed.
-
Well.. as it has been since the beginning of time.... "if it looks too good to be true it probably is". That should be #1.
Next would be the "EPacket" followed by the other stuff you listed.
"The little compressor that could" has been in the field for a bit of time now. I feel like, if used moderately, it is a great addition to the AG experience. By "moderately" I mean not trying to fill 100cf tanks to 4500 psi just because some marketer says you can. Remember the 1400 fps springers?
If I were to consider buying one of these compressors I think I would ask myself a couple questions...
Is it worth $320<> to replace hand pumping to 3k? Answer: To me ? Yes
Can I stick to manufacture's recommendations as far as oils and cooling process? Again: Yes
Will I do the leg work as far as researching other successful purchases instead of trying to find the "pot of gold". Answer: I, for one, can't afford not to.
I must admit... I got very lucky winning the GTA raffle that afforded me a larger compressor. If not for that I would be learning these lessons the hard way right along with the rest of ya'll.
Bottom line: Spend the extra bux and buy one from a state side distributor that others have already had success buying from. Then use it to top off guns and reap the benefits of freedom from hand pumping and wasting shooting time running up and down the road chasing air.
-
Great advice Bill, now, if we could find a reputable stateside dealer that will sell us a decent compressor at a good price... If we had one, we could effectively boycott these Chinese vendors all together. Maybe if no one purchased from any of them, the lack of sales would force a little peer pressure to self police and let the Chinese get rid of the bad apples that will be hurting all their sales!
-
LOL.... only problem there Paul is that 40 GTA members did not buy 40 compressors from the snake. (if he didn't lie about that number as well). We Americans are greedy to a fault. Not to say all victims were American. The way I see it now is... this is what?... 3 times? If a GTA member gets burned again... maybe he should have visited out great little group a bit more often. Then again... I'm pretty sure I'm not the only one walking around that burned my fingers after mom said "Don't touch that, it's hot"
-
Why not start a list of sellers that actually ship the compressors ordered? Then guys could avoid the rip offs.

sold and shipped me one out of LA...4 days later i had a genuine
yong heng compressor in perfect working order !
-
I'm really sorry to see all the BS you Guys are dealing with.
:(
I paid the price for the AV unit just to avoid this type stuff.
I don't have the time to play with scammers.
-
Well, I'm pretty soured on these Chinese vendors on eBay! Not sure what other options are out there that come close in price to these YingYang compressors, but there's got to be something! I wouldn't mind paying a bit more if I knew I'd have a reputable vendor that won't rip me off.
Now, on the flip side, my tracking number is still showing movement! I think we need to start a new thread when these little surprises start arriving so we can share what we receive in place of the compressors we ordered! LOL!
-
Agreed Paul, a separate Ebay compressor scam thread should be started to alert potential buyers not in the know. Although I've read most of the 60+ pages here, I don't think most people are as excited as me about a junk compressor I don't even own yet.
-
Has anyone seen parts diagrams for these Chinese units?
It would be helpful to see how they're built and be able
to compare them before buying. Google search turns up
nothing.

A Google search turns up nothing because apparently these compressors don't actually exist! They are mere figments in the imagination of a bunch of Chinese rip-off artist! Sorry, not feeling the love tonight! LOL!
-
I've read a lot of the thread, but not all of it. Has anyone tried to buy through Amazon? They're listed (for about $400) and I believe ship from China, but for some reason I feel better buying through Amazon even if it is a third party seller on there.
Thanks,
Joe
-
We do one member that has ordered one from Amazon but don't know if he has it delivered yet.
There is a lot of interest in this compressor in that they are a lot lower priced than other options.
It isn't hard to imagine that dealers here in the States that carry the other brands aren't very happy with seeing this low price alternative.
Better yet, it would be good if a State-side dealer actually carried these.
Personally, my opinion is many of the higher options are way over-priced...
It would be nice if someone would start another thread entitled Yong Heng Compressors so that we don't go off-topic when discussing this so we can get away from the ebay only title.

Heads-UP!!!!! The SAME Vendors that sell on Ebay! Now Sell On Amazon!!! Proceed!!! WITH Caution If the Item is {Located in China} and not on US soil!!! I have had 2 Amazon Deals the were a total JOKE! Both items were thought to be in the States by me, As the listing did not say the items were located in china, And They took Forever to receive! I tried to cancel amazon said the items were shipped and in route! If I was not happy when received they would send me a return label and credit my account when they receive it back to Amazon??? > Too the best of my knowledge all E-Bay compressors that were Purchased Here in this post and Located on US soil Were In Fact Delivered Fine, {Chime in here guys am I correct???} I just went back through this thread and Many Buyers who did buy their compressors on ebay from Vendors on US soil. Most of those Vendors have in fact moved their products back to China?? It's very Simple when you go to Ebay search for [Electric-High-Pressure-30MPa-Air-Compressor-System-Rifle-PCP-Air-Gun] Then when the list comes up, On the left of the page Check the US box, It will sort out those sellers located in the US. Research their feedback and reviews! Contact Them for ship dates when it will ship, And how it will ship - USPS Fedex Ups? give them your zip code and ask for ETA, Communicate with them and save your emails from them!!! You may not get a rock bottom price But at least you're going to get your compressor. And remember China is Not our Friend!! They are still our enemy but they Behave so they can in fact still trade with us. {Fact Right now China is going thru some real Financial problems} It is well documented.. If you Research it. Fact we asked China Not to trade or export to N-Korea, And in Fact it has actually Increased!!! That should tell you right there how they they feel about the USA!!!!!!! Jaa
-
I'd also highly recommend looking at the vendors page to see how their feedback rates. Lots of Amazon scammers popping up with zero sales, consumers not paying attention that they're not buying from Amazon and then absolutely nothing showing up ever. I've seen it a bunch with camera stuff and other consumer electronics, I'm sure these compressors will be no different. Caveat Emptor.

This doesn't work as well as you think, I just did this and half the compressors that were on the list were still shipped from China! I think eventually these will make it to U.S. vendors. I think I'll hold off till that happens. As pointed out above, China is still our enemy and even tough these are all produces there, I'd just have more confidence dealing with a U.S. vendor than some fly-by-night Chinese scam artist!
-
No doubt we all love a great deal! I wouldn't sour on these compressors... just the low priced scammers. There's plenty of these that ship from reputable vendors on eBay in the $325-$350 range. I never buy from anyone on eBay without thousands of transactions and a minimum of 99% good feedback. You can't deal with sellers with 28 transactions on a $300 dollar item... from China no less and expect a trouble free experience.
-
Vindicated. Had to say it. ;D
Seriously, quit trying to save a quick fiddy and move on. I'm also seeing folk start to turn sour on the compressor they don't even own due to bad deals.
I can only imagine some idiot uses these compressors improperly and gets hurt and then the entire "cheap compressor" world gets turned on its head. I'm seriously waiting for that. I don't always dig JoeB's sales tactics, in fact never do, but do have to admit he will attempt to keep you safe. I doubt that all purchasers of these compressors will take the time to research the right way to handle these things, nobody here of course as we're all here to learn and share info but I'd imagine a few thousand of these have made their way to consumers' hands.
-
I ordered one from amazon on 8-30-2017 and it due at my door via DHL today...we see what I get...
-
I have only one complaint with my YH compressor, that is that it is causing me and my grandson to keep running out of pellets.
I have had it for almost 2 months now, paid top dollars ($377 delivered) for it and so far it has not let me down. Knowing that it will break down some day I have purchased a backup piston, rings and seals from Aliexpress.
Time will tell if I made a good deal but in the mean time I'm having a lot of fun and getting in a lot of good practice. Bob
-
LOL Bizill. I was waiting for that....
I'm not soured at all.... One is coming my way in the next six months, my winter shooting is minimal at best (30 and 40 below zero does happen here) so I have time. After Avator's words about feeding the animal though I'm not going to play into the games. I'll just spend the $330ish and get one when I'm ready. No rush if it isn't a "deal" ;)
-
I must be "spoilt" as I wouldn't even want to shoot in 50 degree weather. Desert dweller here.
-
I for one am not soured on the compressors, I am wary of the sellers. My sense so far is that those that have received these compressors are happy with them. My perception is that folks are using them to fill gun tanks and top off tanks, running the compressors a few minutes at a time and it's working well for them.
Personally, I am torn. The potential savings is significant and my sense is they could work well for my personal use. I don't mind fidgeting with things, and figure setting up a radiator and pump for cooling wouldn't be all that difficult. I have several spare aquarium pumps laying around. I am curious if I could replace the manual drain with an autodrain, but haven't found much info on those nor their cost yet. All that said, the idea of buying a known good plug and play setup with all the features I want is appealing as well. It will come down to how I feel when I make the purchase, do I want plug and play or do I want to have an adventure. As I get older and more methodical, I feel luckier... sometimes.
I did find a few sellers on ebay that say they will ship from the Los Angeles area, one with 99.1% rating. In digging further on the amazon seller, the one I found is new and has no feedback. I am curious about the DHL shipment that is supposed to arrive today for deerfarm and am hoping it works out well for the him. Please keep us posted on your experience.
Thanks,
Joe

The ones sold on AliExpress costing $350ish seem to be proving legit. The few guys using them to top off guns seem to be enjoying them without issue. That is what it's all about right?

I've heard of being the guinea pig for new products...heck, we are gp's for these compressors it seems, but don't be a gp for new sellers.
My true motivation is jealousy. Ya'll be savin' almost a smooth hundred dollars over what I spent. I say bide your time. Let the scammers out there weed themselves out and when the dust settles, make the purchase...only from verified sellers. I know everyone comes to the rescue for Ebay but I've had NOTHING but bad luck on about 90% of my Ebay purchases in the last 5 years, to the point I stay away and preach to others to do the same. Otherwise take 99%+ positive feedback with at least 50 transactions as the only sellers to buy from. 98% don't get my money. Sure, I've gotten my money back via Ebay/Paypal but what a waste of time.
I wanted to replace my Yong Heng female "foster" quick detach with the reliable one from AirVenturi. Yong Heng had m10x1 threads and the AirVenturi quick detach has 1/8"bspp. NOBODY makes or sells an adapter. I found one on ebay from, granted, a reputable seller, but even they got it wrong. They sent 1/8"bst vs bspp and I emailed them various times complete with high res close up pictures showing the taper vs a bspp and the dude said I was wrong. Don't EVER argue with Bill Gates! I had to send it back for a refund. Ebay did pay for shipping but that not worthy for Ebay as they didn't make money on that sale but had to pay return shipping.
Sellers do put the hurt on Ebay far worse than any buyer ever could. So to answer any questions, that's why the scammers do what they do. Scammers get paid fraudulently and Ebay has to make it right in order to keep their business a functioning reality.

That's an auction and not a Buy-it-now" which many prefer. If you're in no hurry and the price stays low and you snipe that auction at the very end, then I'd trust that seller....MAYBE. He's got no past transactions for sales on this compressor...
I miss the days when if you were the one with high speed internet vs everyone else you could place a last second bid and win the auction when the person you're in a bidding war with thinks you've given up in those last 5 seconds!
On second though, I wouldn't buy from that seller. I just perused through his history and items for sale. Something is off...
-
Just type in pcp compressor. As you scroll through the listings all the ones shipping from China say so right there. The ones that don't say China are usually shipping from la. The first two that come up ship from la however they only have like 8 transactions. Look for one with thousands. There's a lot on there shipping from la from high volume sellers with 99 or above satisfaction. All the good ones show shipping dates no later than September. Even from china
-
Yup, that's 'ole topsee6666 again.... look at the feedback. These scams are relentless. Ebay not worthy nowadays.
-
Best one currently from la seems to be cncmotorshop. $345 and they have more than 2000 transactions. Higher than 99 rating

I'll let you all know when I receive mine, from which seller I purchased.

looks like this on the front porch...

As previously noted, I did not particularly like how these compressor transactions have been handled but I will disagree with several here who state they would not do it and report problems with eBay. The first compressor scam was the only issue I've ever had with eBay over probably 100+ transactions covering more than 5 years and that issue was handled acceptably. Things do seem to possibly be changing but the guarantees seem to work fine at this time. Having the compressor in hand is a very nice thing for any frequent PCP shooter (even though I already had a Tuxing unit running fine) and the YH unit did arrive promptly and very well packaged from the above noted second vendor. If you want one and shoot enough, order one. You will probably be satisfied with the transaction as I am now.

Could you please repost the details of the purchase... where, when, how much.. for those who want to at least get a compressor instead of a sharp stick in the eye.

I'm surprised that nobody has fabricated a self-contained liquid cooling option (Radiator, fan, reservoir, tubing, fittings, aluminum mount, propylene glycol/distilled water mix, and a 12v out to Molex) . I've built plenty of computers with them.

can I ask which tuxing unit you have? I might be interested in getting the tuxing unit with the self contained water jacket head. Is that the one you have? I have a yong heng and would like to compare between the two.

I bought it on amazon,seller was Selene Allure,its price was 369.00 and I had some cash back rewards which brought the price way down...it shipped 8-30-2017 and arrived 9-6-2017 via DHL from china...I set it up and it refills my mrod very quickly.

Kris, I have the Tuxing which has the smaller head if you look at pictures of the two models commonly seen (I've seen it referred to as the "newer" model). Not sure what you are referring to as "self contained water jacket head" as both have water cooling similar to the YH and the head on the Tuxing is basically the same as that on the YH. The Tuxing I already had has auto-bleed and auto-shutoff but I usually operate it manually since I only use it to fill guns directly at this point. I bought the YH because the price was reasonable enough get one for a backup and people seem to have had good luck with them. Also, the Tuxing is 220v that I run off a transformer and the YH is 110v so simpler in that respect. I do prefer the plumbing arrangement on the Tuxing as it is a bit simpler and very easy to attach the cooling lines.

thanks.... the tuxing I was interested in is the one with the bigger head of a diff design. No exposed stainless lines going from diff stages. Presumably it's all internal.
Thanks again

Nice to see a little positive in this thread. Hopefully all have been made aware and we can begin seeing more successful purchases.

I got my oil today and got it all setup to do a test run to check for leaks after pressurized to 3000 psi. All went good and it only took about 30 seconds to fill the gold filter and lines to the 3000 psi. Held pressure for 15 minutes so will update with pics and more tomorrow.
Mike
-
I got a gallon of AW46 hydraulic oil I ordered shortly after ordering the compressor. So, now I have oil, but no compressor! I guess I'm ready for when I do find one...
-
Hey Mike..
Do that a few times and just bleed it off to chase all the oil out of the system. Then check your filters.
-
Ok got the initial break in runs to iron out any issues and had a few small leaks to fix with new o rings. Filled my first tanks with it starting with my 80cf scuba tank to 3500 psi.
Started with 3000 psi in the tank, compressor at 25C with gallon ice jug in bucket, ran the compressor for two 15 minute cycles to fill the tank to 3500 psi, temp climbed to 62C after 15 minutes then allowed to cool back to below 30C then second run cycle to 3500 psi and 62C temps. Total tome to fill 30 minutes. No moisture from tank when bled off, slight water vapor from compressor high side bleed at both the end of first cycle and second cycle big gold filter is working fine.
45 minute/66cf SCBA tank from 3900 psi to 4500 psi, run time of 15 minute to fill to 4500 psi and a temp of 28C at the start to 62C at the end of the fill. Same as before for no water vapor from tank bleed but water vapor from compressor bleed.
90ci buddy bottle from 3500 to 4500 psi, run time of 5 minutes to 4500 psi and temp of 28c at start to 59C at end of fill. No water vapor from the tank at bleed and slight water vapor at compressor bleed.
Overall very happy with this compressor right now and its nice to be able to fill all my tanks in less than two hours versus all day with the shoebox.
Here is pics of my setup with the gold filter and needle valve after the gold filter so I can isolate the tanks from the compressor to allow bleeding of just the tanks and hose after the valve so no moisture can migrate from the filter to the tanks easily.
Mike
-
Replied in the other thread.
Good job.... another success.
-
Mike,
Nice setup!
Your fill times/temps mirror mine, one addition. I also have a 30min SCBA, about 10 min to top off 3800-3900>4500.
these are good compressors IMHO. Use them as they were designed, keep them reasonably cool, should last a good amount of time.

Yes I agree with all you said and believe that heat will be the killer for these if allowed to overheat repeatedly. I am going to add some charcoal to my filter and add another gauge between the gold filter and the tanks or guns to monitor the pressure better due to a better gauge that was on the shoebox. It also has another bleed valve in it so I will have several points of control for releasing pressure from the system.
Mike
-
Someone also mention to leave the bleeder open and let the compressor run a few seconds to bleed moisture off the head(s).
-
Wouldn't running ice water through these at those temps cause condensation inside the compressor?
-
Someone also mention to leave the bleeder open and let the compressor run a few seconds to bleed moisture off the head(s).
I do open the bleed on the compressor after I have filled the tanks and bled all pressure off. It should make no difference if you run it at 0 psi with bleeds open or open them with the compressor still running. The high pressure bleed off should remove most all moisture if opened up to a high speed blast during bleed off. After I have closed the tanks valves and bled off the pressure from the tank side of the on/off valve I open the compressor valves wide open for a high pressure exhaust flow of air.
Mike
-
Wouldn't running ice water through these at those temps cause condensation inside the compressor?
The water is not ice cold as the head temps before starting to fill is only 24C or so but even if colder the running of the compressor with bleeds open should remove any residual moisture. I guess time will tell with that if longevity suffers from it or not. The 3 gallons of water in the bucket melted the ice in the jug pretty quick so it never gets really ice cold but just keeps the water from getting warm to the touch.

Hi All,
I just wanted to share this excellent review from youtuber Joerg Sprave on the Yong Heng compressor.
https://youtu.be/7NdnItyJs-U

I watched that video and explained to Joerg that he needed a better water filter, and I got shunned. Oh well, wouldn't be the first time someone didn't listen to me when I was right.

i think Joerg done an awesome job of checking out the YH !!
he's got it going on...... 8) thanks Vince

Well I think I'm actually in this time. Just ordered the hardcover model for $327 shipped from this store (https://www.aliexpress.com/item/300BAR-30MPA-4500PSI-High-Pressure-Air-Pump-Electric-Air-Compressor-for-Pneumatic-Airgun-Scuba-Rifle-PCP/32815880523.html?spm=a2g0s.8937460.0.0.n7WDO9). Says 10 days or less to the U.S. and lots of orders.
I'm pretty sure this is an actual seller with actual compressors.... I think. I will believe nothing until I actually have the compressor hooked up and compressing (hopefully) clean, dry air into my scuba tank (top off of course, it's sitting at ~2400 psi right now).

That's the compressor company store so you should be good to go and have a compressor in your hands within 10 days.

Yep got to love technology and manufacturing progress to allow the prices to come down drastically in a few years. That and the up surge in air gun sales and use creating more demand than supply which is always a good thing. Competition breeds innovation.

I strongly suggest the yong heng owners to purchase this on eBay
https://www.ebay.com/itm/361454297221 (https://www.ebay.com/itm/361454297221)
Had the water pump stop pumping and this flow indicator reveal it. Second time this has done this. The pump lost its prime. I just reprimed and it is working again. I'm going to order a new pump.

Ken, that is a very wise suggestion and necessary item. I have one on my compressor and I have seen the pump loose it's prime 3 times and that little gadget extended the compressors life. Bob
-
I haven't had my water pump stop yet... I keep the return line clipped to the top of my container. The end is above the water line, I can easily see if flow stops and its one of the many things I'm constantly watching ;)
I did have my first event today. About ten minutes into a scba top off, I looked over at my timer to see if I was close to a water bleed, just as I did POP!!! didn't see what caused the pop. Shut the tank valve, opened the bleeds and shut off the compressor. didn't see anything wrong, all connection made, nothing looked out of sort.
So, I flipped the compressor back on, let pressure build to about 1k, shut if off and immediately found the leak at the black pre-filter, O ring blew 8)

I'm thinking of replacing my water pump with a 12vdc pump. Just don't like the idea of dropping 120vac cheaply made pump into a water bucket.
Found this one: https://www.amazon.com/mountain-ark-Submersible-Amphibious-Hydroponic/dp/B010LY7P3Y (https://www.amazon.com/mountain-ark-Submersible-Amphibious-Hydroponic/dp/B010LY7P3Y)
(It's a couple bucks cheaper on Ebay).
My compressor is running fine. I don't even use the water pump when topping-off the PRod from 2000 to 3000 PSI.
It takes about 15 seconds and temperature only gets up to 35C (95F). Not even as warm as my coffee.
Normally I shoot 15 to 20 pellets a week (rodents), so I'm only topping-off the PRod about once a week..
-
When filling my first time on the 45 minute SCBA tank when the compressor gauge got to 4500 psi my tanks JB gauge showed only 4400 psi so let the compressor run to get a full fill of 4500 psi. Well right before the tank gauge reached 4500 psi the burst disc on the compressor high bleed block blew and scared the dickens out of me. Replaced the 5k disc with one supplied and was able to fill to 4500 psi with no issue.
I measured the discs at .005" thickness for 5K rating and the 7500 psi discs are .008" thick so may replace the 5k disc with a .008" thick disc to prevent regular disc failures in the future.
I have my return line above the water level so can see a visual stream of water flow at all times.
Mike
-
I am replacing my water pump as I don't trust it anymore. The flow indicator is still another way to also verify the pump is working plus it looks cool watching the impeller turning imo😁
-
Mike,
I was concerned with the burst disc letting go to easily. Several reports of this so far.
I'm still on my first,knock on wood!. I have about 13 hours of run on it. I mostly fill 4500psi tanks.
I have no idea what it measures, I'm not pulling it ;) my 4 included spares, are .005.
I have a die punch cutter. If I have a problem with them, I'll order material to cut my own.
-
Would a small 12volt Marine Bilge Pump possibly be a better choice for you guys? Rule makes a compact 360gph unit or is that too much flow?

I cut new discs for any of the ones I have that blow using a single hole paper punch and have found it to work very well. I have found that a rule of thumb for thickness is .001" per every 1k in pressure you are wanting it to protect and has proved true for me so far. I use K&L brass sheet stock found at most hobby stores.
I trust my JB gauge on the SCBA fill whip over the one that comes on the YH compressor.
Mike
-
Mike,
Thanks for the info. I was planning on using K&L brass sheet. I'm also in to R/C planes, helicopters and more, used lots of K&L stock over the years.
I also trust my SCBA gauge and the gauge on my fill adapter over the YH. My YH gauge reads about 200-300 psi high.
-
John
I used to race 1/10 rc cars on and off road, mainly rc-10 in the early 80s to mid 90s in Florida. still have my 5 cars and support equipment today.
My scba has its own gauge to show tank pressure and then the JB gauge that comes on the whip. My compressor was reading about 4600 when the disc blew so it may have been weakened or compromised before I got it. So I guess mine about 200 off since the JB and tanks gauge were at 4400 psi when it blew.

I have to say, the shenanigans with these compressors never ceases to amaze me. I had submitted a best offer for this compressor on ebay, (http://www.ebay.com/itm/182547974004?ul_noapp=true) never heard back, emailed, didn't hear back and ended up retracting it because he couldn't confirm shipping location. But last night, the seller sent me this message:
Dear friend
We are very sorry for the later reply due to the weekend.
This product have already sold out and if you need,we can ship from China to you and give you tracking number.The price can USD335
If there is any other question,pls feel free to contact us again
Best regards
May
Yet, nowhere on that ebay listing does it say anything about being out of stock and that it's actually going to come from China.... It still claims 8 in stock, in " Los angles"
Just posted this to say that if you're buying from eBay it would be advantageous to contact whatever seller you're thinking of purchasing from just to see if the details in the listing are correct. I've never seen so much misinformation and fraud with a specific niche product like this in my life!! LOL I understand why Bizill was going off after the 3rd "deal" was posted for these.

When I was 17 (1963), working in a Navy FD shop, refilling CO2 cylinders, I made a big mistake with over-pressure discs.
The CO2 pump popped a disc every couple of weeks. Sounded like a rifle shot. Scared me every time.
I replaced a popped disc, with two disc.. It worked! No more blown discs.
A few months later, I was training a new guy. I was telling him to do each step on the check list.
While I was getting a new source tank, he skipped releasing the scale arm lock (and balancing the arm+15 pounds).
I removed the empty source tank, strapped in a full tank, connected the output line, flipped it upside down.
"Okay, what's next on the check list?".. He started the CO2 pump..
The 15 pound CO2 bottle on the scale was filling up. It went over-pressure, but the pump's double-disc held solid.
I was watching the yellow tip of the balance arm, and it never moved up.. I was reaching for the Off button,
when the 15 pound bottle split open, releasing 15+ pounds of CO2 into the small shop, which was at about 90F.. Instant White-Out!
Sounded like a bomb! Lots of damage (windows, doors & etc) our ears were ringing for a week! Lucky no one was seriously hurt.

This is beginning to sound like a coordinated financial terrorist attack specifically targeting air gunners! Maybe we should alert Homeland Security! Or, maybe it's just a bunch of anti-gun left wingers trying to divert blame on China! So many possibilities! :o

Reckon that nut in N. Korea has something to do with it?

That "Los angles" is the one I submitted an offer for........they have great feedback. Hope they are legit.

I think they are, I just think they're going to ship Fedex IE out of china (not that there is anything wrong with that, Fedex IE is pretty much 5 days guaranteed customs cleared to the states) instead of out of LA. No way that seller is going is risk their 2000 feedback, 3 year history for a scam (at least I can't imagine why they would???)
I just don't like them not disclosing on that listing that they're sold out in LA is all.

I had thought about doubling up on .005" discs awhile back when I had one blow in one of the 90ci bottles I had at the time but decide it to not be a wise idea for just the reason you stated here. I just replaced the blown disc and never had a issue again. I think some discs get overstressed after numerous fills and just give out prematurely. Thats what they are designed to do so it just a fact of dealing with HPA. Rather have the disc blow than the tanks itself.
That's why I only use one disc and never go any thicker than a few thousand from what was in it from the factory.
Mike
-
Yeah, it's smart not to change the spec on the disc. I was a dumb kid and figured it was a problem with the setup.
But, thinking back on it, I was refilling a couple dozen extinguishers daily, mostly with 15 pounds. A few smaller.
I'm guessing the discs were getting 'worked' during each fill. After metal is worked, it can break.
Heck, maybe I was over-tightening the bolt on the disc.?.
Every day, I was emptying out about 300 pounds of CO2 in front of the fire station. Then I would start re-filling.
I had to get another trainee, the forgetful guy didn't work out.

Hello all,
I'm new to this forum and wanted to mention that I did get the Yong Heng compressor off ebay a few weeks ago from a vendor named nice-shop2 for $357.69. I was originally going to have it shipped from China but after I paid for it the vendor contacted me and offered to ship from LA. So after agreeing I got it just 2 days later. I did get the Chinese high side dryer and the molecular sieve. Thanks to those who provided the links on this forum. I tried to copy Mukilteo's idea with the red wagon but the wagon I ordered from ebay smelt so badly of a cross between gasoline, mothballs and model airplane glue that I tried to return it. But eventually got tired of playing tug o war withe the vendor that it now sits in our tool shed still in the box. I ended up buying a Gorilla Wagon from Home Depot and have it set up pretty much like Mukilteo's set up. The only trouble I had with the compressor was connecting the air hose to the connection and getting it to seal. Not realizing at first there is a Delrin washer inside to the connection, I was afraid of stripping the threads. So now I have it snugged up with some plumbers tape with most of the pressure on the Delrin washer.. Seems to works fine. I use a 1 gallon bucket with ice and just top off my guns when needed. I do have 2 steel 3500 psi scuba tanks I had been using before getting the compressor but since I plan on getting back into scuba diving some day I wont be using the compressor to fill the tanks. Soon as I figure out how to post pics I'll show it.

Welcome Veronica...
That should do it... Make sure your water pump is on the bottom of the bucket and your return hose stays at the top. Some folks have complained about those water pumps failing, keep an eye on it.

Yeah, thanks to the great advise on this forum I did get that right. Also I'm looking at getting one of those indicator impellers to put on my water line as extra assurance in case the water pump does fail. Right now I'm running the return hose to the top of the bucket so that I know it's flowing. I'm not running it too long yet. Just topping off my guns as needed.

As for the impeller indicators.... I'm gonna go a different route here. I'm going to use food coloring in my water. That way I can see the water moving in the return hose at a glance without staring at the indicator. Hopefully it won't dye my hose too quickly.

I would definitely trust that seller, they're not going to up and disappear like the other scammers with a 17k+ 99% feedback. Pretty good price also, that is the lowest I've seen on the Auto stop 110v (by about $10 I think).
-
Yes I think so, will prob order from them.
Do these pumps have a thermal cutoff safety ?
It should not be hard to install one if not.
-
"thermal cutoff safety ?"
I don't think so. The 120vac version doesn't have one that I can see.
One thing that might help mechanically, is a layer of firm shipping foam under the foot-pads of the compressor.
On my setup, it cut down on the noise and vibration from the table it sits on.

LOL.... I put a Dale Earnhardt Sr. stadium seat cushion under my AirMax MKII. Made a HUGE difference.
P.S. Didn't make it run any faster.

I see this one from ebay seller ashleytrade1984(17746)
high positive feedback and has the newer unit with cyclone water removal and adjustable switchoff pressure
anybody bought from this seller ?

Definitely the best price I've seen on eBay, especially if they are willing to take an offer it'll be cheaper than aliexpress as well for the top model Yong heng. Here is the best price I've seen on aliexpress for that adjustable one:

dangit, ya'll get 110 volt WITH auto shutoff for less than what earlier adopters paid. Lucky!
-
"auto shutoff".. Is that like driving one of those new driver-less cars? You can take a nap while filling your tank? ;)
Sounds like Trusting the IRS.. :o
-
Agreed. But if I were to have a stroke or baby-momma wanna pull me into the bedroom then I'll at least have one fail-safe working for me. Ah, who am I kidding, I'd be done before my Yong Heng fills up my Prod. ;D :o ??? >:( No need for auto shutoff.

I don't see anything in the description of the eBay auction lennyk posted that says that compressor has the Auto-Stop/Shutoff feature - am I missing something? Also, besides the Seller offering a 60 day money back guarantee, do these Yong Heng compressors have any stated/implied warranty from the manufacturer, Yong Heng?
-
Geez you are right. The picture is of the adjustable model but the description doesn't say it is. Anyone buying better confirm the picture is accurate. It does give the fill rate as 50l/min so it's at least the hardback model. Be rotten trick though if it's not the adjustable version
-
When I purchased mine two months ago I originally ordered the 220 model because the add stated that it had an Auto shutoff so I emailed the supplier to explain how it was adjusted. I was told that it was an AUTO shutoff when it reached 4500 PSI but was not adjustable for different set points so I ordered the 110 volt model which has neither. It's so fast that I don't mind babysitting it. Bob

I think I remember seeing that you could order them set to shut off at your desired pressure.
-

Yeah it depends on the model. The top model has adjustable pressure. The next one down shuts off at 4300psi and the next one doesn't have that option but still has the water/oil separator and fast filling, and the cheapest model is slower and doesn't have theoil/water separator apparently.
Here is a picture of the different models.

mouse over each small icon next to the Voltage choices at the following link
there are 4 models each in 110v and 220v and priced accordingly
Automatic...shuts off at 4500 psi
Set Pressure...shuts off at the pressure you select
Hardcover...must be shut off manually
Simple...must be shut off manually and there is no cyclone filter (water/oil separator) which is on the other models.

The "Hardback Edition" has that extra water trap/bleeder, which I think is nice to have.
But, the extra 'control' hardware that needs to interface with the HPA just seems like more things to go wrong.
If I had to take a phone call while doing a fill, I would just shut it down (bleeding out any water) and come back later.
But, that's just me, and I only need about 15 seconds to top off my PRod.. Maybe around 60 seconds for a rifle..?.
You guys filling up scuba tanks might not want to watch the gauges. (My scuba tanks are all over-due or obsolete)..

A pressure switch is actually really simple in design. All it is, is a simple contactor that gets pushed open when the pressure is high enough.
It's basically the same principle as the pressure gauge. So it does have a remote chance of malfunctioning. But so does the pressure gauge. The odds of it failing is about the same as the gauge failing.

Anyone who fills airguns knows to watch the gauge on the rifle, to make sure it matches the supply gauge.
The pressure gauges I've used over the years were pretty accurate. Those that got hammered too hard, too many times,
didn't become inaccurate, they visibly died with clear indications of failure. Like a broken indicator needle or bent needle,
stuck at 1200 psi etc. The only meters I've had to replace on air guns, were cheap (paintball style) meters that leaked.
It seems like the design of a pressure sensor electrical switch would have to be more than a simple piston pushing a coil spring, until it opened the circuit.
The first worry, is the piston might have leakage, that would allow moist air to flow into the innards.
If the switch opened slowly as pressure built, the contacts might arc and weld the parts into a short.
If the switch plused open during the piston pressure stroke, and closed a few times, that could cause a welding action.
(These 120vac compressors use pretty high current).
So, unless it was a low voltage switch, isolated from high current by a logic controlled SSR,
the switch arm would need some kind of mechanical arrangement to make it Snap open quickly.
Like the clean hysteresis switching of a thermostat.. :)
We need to face the facts. Using these Chinese compressors might be very risky.
(Us first adopters are the crash test dummies).
Adding extra risk (by dependence on automatic operation) might not be wise.
I like to drive using cruise-control. Millions of people have logged millions of miles with cruise-control
and now we have a pretty safe 'automatic' device.. But, I'm not ready for the self-driving car.. :)

Eh? To each his own?!
I'm not here to convince you otherwise.
Just saying that it's not as scary as you might think.
Think of it a ABS on your car.
You still need to watch it but it's an added safety feature, incase you get distracted. Not a "set it and forget it" sort of thing.

the units are well made and IT DOES NOT SCARE me to use it at all.i fill rifle up directly.unit runs for under 60 seconds when filling rifle.it really does get hot at all.the water cooling is a plus.i cant shoot enough now I don't have to pump and need more ammo...don't be scared to buy and use this unit...respect it and follow directions and you will have a compressor that will pump up your rifles for many fills.

thanks guys ! i thought they done snuck something new in on me....... ;)

That "cyclone separator" has some open space on it's face. About 23mm wide x 57mm tall.
I wonder if you attached a peltier cooler unit to that area, and cooled (30F?) down the whole cyclone separator body,
to lower the dew-point inside. Would that increase the effectiveness of the moisture trap?
https://en.wikipedia.org/wiki/Thermoelectric_cooling
Would it trap enough extra water to make it worth the cost?? Any engineers here? ;)
-
Inside look of the Yong Heng "cyclone filter." Spinning air passing through the filter housing is supposed to fling off oil and water and collect in the cavity below which then is drained off by opening the bleed screw.

Golden filter, xiamen SUBANG technology, makes me wonder on the material.... I would not want one go subang on me.
Someone hydro the darn thing just to be safe.
Interesting design on the water separator, that could actually work.
Peltier idea is neat, but you should calculate how much energy there is to be transferred, and you'll need pretty good heatsink or a waterblock for it. 50-80W peltier would be the smallest that I would even reconsider.
Marko
-
Rws_53,
Thanks for the pics!
I had no idea the low side separator had a sintered filter.... something that should probably be cleaned now and then.
Marko,
That's on the low side, pressure shouldn't be a concern, should it? I'm honestly not sure what the low pressure side pressure is....
Of course, the high side is probably the same set up....that would be a concern.
-
John, I was referring to the golden filter, it sees the full 300bar pressure. It should be hydro tested to a minimum of 450bar and desing should withstand 3 times the working pressure without rupture. Thats ~900bar.
Makes me wonder does it actually hold that?

Got ya, I thought you were talking about the gold color sintered filter in rws_53 picture.
Yeah, I wonder about my gold high side filter... but, it was "hydrostatic test 50MPA completely" Does one really need more reassurance? ??? ;D
I'm rolling the dice for sure. I don't even know of anyone that could hydro test it, or, I would have had it done just for piece of mind. I will say, it appears to be thick enough and has plenty of threads at the end caps to hold the PSI were dealing with, assuming the material its constructed from is OK....
-
Gentleman,
check your cyclone separator!
Mine was not cycloning... the cyclone sleeve had unthreaded itself(assuming it was threaded on to begin with) and just laying at the bottom of the separator housing...
Sleeve is back on the body and tight, might actually work better now...
-
is the oring 1 of the spares that came with the compressor ?
before i remove it, i'd like to have one on hand...just incase :o
-
pretty sure its this one, so yes its in the bag. Mine was not damaged at all, I just reused it. Honestly, I don't worry about O rings. I have several metric and imperial kits plus a TON of bags full of O rings, unless its a thin CS, I probably have it ;)
-
ok thanks, and we appreciate your research on the YH-GATE !! ;)

I followed this string a very long time before opting for the Carette compressor from airtanksforsale and their alpha filter. I like that it is completely self contained..no need for external cooling tank. I am more than happy with my set up. I believe the cost associated with going this route over the less expensive unit will pay off in the long run. There are several guns that I didnt buy while saving for this and I appreciate what I do have more. Overall well worth it

I think you'll love it Jim. Everything I've seen definitely looks top shelf for a Chinese compressor, if you're willing to part with that much cash for a Chinese compressor.
I'm hoping by the time my Yong Heng dies the Carette's drop in price a little (or someone tears apart the mrodair one to see if it's the same as the one Joe is selling).
-
Jim,
I considered the Carette, actually I'm still considering one. I'm waiting another year or two before I commit.
With the Yong Heng, the cost is low enough to make it disposable if it totally self destructs. So far, its working fine and I've been able to get parts that SHOULD keep it running for a longtime.
The Carette is no doubt the better compressor. Still, at $1400+ its not disposable in my book! What happens if you need a part? does Joe stock any? I have only found Joe and Huma selling the "real" Carette compressor. Some other sellers have compressors that look like carette's, these are reported as "knock offs" and not as good. Heck, I can't even find the Kalite/Carette manufacture website.....
-
it takes me longer to fill water cooling bucket than it takes to fill the Mrod from 1700psi with the yong heng...I now need to hook cooling system up to a water supply I can turn on and off instead of a pump in the bottom of a bucket of water.
-
Mark,
I use one of these.
https://www.amazon.com/Arrow-Products-00744-Container-2-5-Gallon/dp/B008VET4Q8/ref=pd_sbs_79_1?_encoding=UTF8&psc=1&refRID=BFVGR2XSM0H19M8VSTD9 (https://www.amazon.com/Arrow-Products-00744-Container-2-5-Gallon/dp/B008VET4Q8/ref=pd_sbs_79_1?_encoding=UTF8&psc=1&refRID=BFVGR2XSM0H19M8VSTD9)
I keep it full of water w/water wetter added. I store it on the door of my beer fridge. I'm doing smaller tank fills, so, with the smaller volume of water, I can run longer since its cold. Pull it out, screw off the big cap, drop in the pump, clip the return line to the lip and turn on the pump. Much simpler than filling a bucket each time and allows me to reuse the water and wetter.
I did plug off the spigot since its of no use to me and just a risk for spills...
If I had a water tap and drain that was not in a bathroom or my kitchen, I'd do once thru cooling as well ;)

I'm betting the carette mrod air omega Venturi compressors are coming from the same factory just rebranded. My diabolo air dry system is a good example. Mine is red with nice lettering for $179 not including shipping. AliExpress has the same one gold color for $79 shipped. Take a look at the Diana stormrider same as mrodair varmint just rebranded. Are these guns knock offs? I doubt it. Same as the compressors doubt they are knock offs. Just rebranded color difference is all😎
-
Ken,
You may very well be right. However, I do know that in cases like this, where different names are stuck on the side, QC and quality of parts can be different. Not saying they are, I just don't want to be the guy that spends $1250 only to find out later, that had I spent $1400, I would have got a better product ;)
I won't be buying one until they are on the market for at least another year. Even then, If I don't see a demand along with a parts supply, I won't be buying. I'm not throwing that kind of cash at something that may be obsolete or parts can't be found for in a few years....
-
technology has evolved and fast becoming commoditized
the good thing is the Chinese make changes fairly fast.
the current crop of these compressors all carry the same basic 2stage piston design
just like the generic 3stage hand pumps which can now be had for $50
shoebox etc are gonna be considered stoneage soon.
I was gonna build a motorized hand pump but may not make sense anymore with the price of these compressors.
-
It actually does make sense.... With the price of the hand pumps a guy could make a dual motorized hand pumper that would be quite efficient. These hand pumps are self contained water cooled (in some cases) and a steady slow stroke would work great. And the fun factor is just an added.

Man, 8 days (including weekends) to the midwest from this seller (https://www.aliexpress.com/item/300BAR-30MPA-4500PSI-High-Pressure-Air-Pump-Electric-Air-Compressor-for-Pneumatic-Airgun-Scuba-Rifle-PCP/32815880523.html?spm=a2g0s.9042311.0.0.BZHSrl).
Fedex dropped it on it's head and bent the tube coming out the top slightly (not kinked off shut, but I'll need to replace it eventually). None the less, didn't seem to hurt the performance at all. Filled my scuba from 2k to 3k in 18 minutes and never got over 53c on the temp gauge (I did put 3 cups of ice in the 5 gallon bucket). Bled moisture regularly and had zero moisture at the yoke on my scuba and very little on the input side of the hacked golden filter. My scuba is due for inspection in December so I'll be getting a visual done then, will be interesting to see how it looks (I will report back- good or bad).
Very, very impressed with this $300 compressor and $100 filter. Now to start hot rodding something.... 8)

What temp is normal for the compressor and what is considered overheating?
-
The paper work that came with mine said not to exceed 65C.

Thank you! 149F would be a bit hot!

Are a lot of people having trouble with their compressor getting hot?
I wonder how many hook up the water backwards? ???

Mine seems to get hotter than some others on hear, but I should probably use a bigger pail. I never use ice. Biggest bottle I fill is 22ci.
Does it really matter what way the water runs through the head? I wouldn't think so.

Mine got up to 34C (93.2) today when I topped off my PRod. The last time, it got up to 35C.
I think it didn't get as warm this time, because the basement is getting cooler. I guess winter is coming..
Since the compressor only runs about 15 or 20 seconds when topping off the PRod, I don't use the water pump.
I'll start using it again, when I start shooting the rifles again..

I'm not really sure. I think if you have the top as the inlet you have the potential for cavitation in the top of the head and also if the end of your water outlet tube was below the head this could create a syphon effect resulting in basically a small stream of water running straight down one spot on the cylinder. If you fill from the bottom, gravity pretty much insures neither of these can happen. No testing or proof though. LOL. 8)

it matters which way coolent flows so hook unit up per instructions and use a five gallon bucket of cool coolent per large fill and there should be no problems with heat unless unit is running for hours then ice or a coolent change will help keep things cool.running these unit for just 15-20 seconds without coolent WILL take away from its extended life without coolent.would you run your car just a short time without coolent?yes you could but heat would build up and cause damage in time,would you run your car with no oil for a short time?you can and it may not cause damage right away but extended life of that engine would be shortened.

What do your instructions say? Mine is something like "make water good attachment, happy temp keep" or something along those lines... I have to say, I did make the water good attachment and I have been happy with the temp keep, so I guess that part is correct. :P

the instructions I received with unit were not as clear as those instructions posted above but it did specify to hook water lines up according to intructions...it was not something like this or something like that it was clear to where to hook inlet up at and outlet up at...I have just used it to fill rifles not any air tanks and never did temp go above 30.9c...
-
I know it's not the same but, my MKII AirMax has a larger tube for inlet and smaller for outlet. They can't be confused.
-
That settles that. There is a right way and a wrong way. Thanks for posting that. Mine is not nearly that clear either.
I do wonder if those with heat problems have them hooked up backwards though. I ran 12 minutes last night with no ice and the temp only got to 55c; well within the recommended limit.

Rich,
Are you not using any kind of supplemental dryer aside from the small black one that comes with the compressor? Are you seeing any signs of moisture in your guns? Is the tampon in the black filter getting wet at all? With my unit it takes a little while for the air to work up enough pressure through my high side dyer before it then fills my guns pretty quickly.

Nope, not using anything extra. But, when filling larger rifle cylinders, I did stop the compressor and open the bleeders on both sides,
at least 3 or 4 times during those fills. (depending on how much pressure was already in the cylinder).
I don't recall ever noticing any real moisture spray when bleeding. (Unlike on my little garage compressor)!
Maybe the amount of moisture was too small to detect, when it blew out..?.
The relative humidity in the room is never over 50% during compressor operation.
The small tampon filter looks exactly like it looked after the first time I used the compressor. (Dry, with an oil spot).
There is a bit of hose & filter delay, when I top off the pistol, but it's very short. Maybe <10 seconds.
This compressor is so fast, I have to be very quick when topping off, else the PRod meter is in the red.
I've had a couple of slight over-fills. I dry fire 2 or 3 shots to move back into the green.
Because the small filter has remained dry, I don't feel the need to open up the PRod cylinder for inspection yet.
Cheers,
Rich

-
That feels a bit more reassuring. Its just hard for me to know what the inside of a a gun cylinder looks like. I'm using a high side dryer with molecular sieve on my rig without a liner. I'm going to be keep a close watch to make sure there are no signs of corrosion on the inside of the dryer and then if there is I plan to switch to activated alumina 1/8" beads. I do notice it does take longer to fill my guns with the inline dryer installed. Before adding the dryer it took less then 10 seconds to fill my Hatsan AT-P2 and afterwards I didn't see any sign of moisture on the cotton tampon so I'm hoping that cyclone water/oil mechanism on the Yong Heng hardback version helps.
-
I will be filling my 90 cu in bottle inside with the A/C on, so relative humidity is VERY low. I wouldn't worry about moisture too much as it will always come out of the gun when shot. Unless you live in Brazil or some where. You will most likely be ok.
-
Where would one obtain these extra dryers?

Help! Leaking Filter!
The little black filter had a leak before and I changed some of the seals between the filter cap and the quick-connetor to fix it.
Not sure what I did, but it suddenly stopped leaking.
Yesterday, when I really needed the compressor, (setting up a scope on the PRod) it started leaking again!
It worked fine a few days ago, then yesterday morning, it leaked right off the bat. First top-off of the day failed.
While the compressor is running, I can feel air coming out around the quick-connetor, but can't pin-point the exact seal..
Has anyone here had this problem? Did you pinpoint the problem?
My quick-connetor is okay, since I can use the compressor without the black filter installed..
Thanks,
Rich
-
Thank you!

Rich, There's an O-Ring in those quick-connectors just above the balls, If you don't see one maybe it blew out?

That O-ring is good. My quick-connetor is okay, since I can use the compressor without the black filter installed..
I had to get some air in the PRod, so I took the black filter out-of-line..
Don't want to do that too much..
-
Richard,
There is a plastic of some sort, seal in the threaded end of the QD. Sounds like it might be sealing on the hose but not the threaded end of the black filter? Or, you may have bad O ring's (there are two) in the QD, the weight of the filter vs the hose may be why QD doesn't leak when attached to the hose...
There is also the O ring for the black filter housing, it may be leaking, and seem like the air is coming from the QD. I've had to replace this O ring twice now. One leaked, one blew out...
-

Yeah! It did make it seem like the leak was at the QD! I could feel the air down at the QD..
When I checked it (just now), I said, "that can't be leaking", because I couldn't feel any air coming out of the housing..
Then I put some talcum powder on the fittings. The results looked odd. Flipped it upside down and did it again!
The air coming past that large (30mm?) O-ring blew away some of the powder.
I had visually inspected that O-ring and it seemed fine (didn't remove it). I just replaced it, and it still looks okay.. Why?
Did a quick test and got some good pressure.. Maybe there was some small piece of fuzz on the O-ring.?.
The other day, I took the filter housing apart to take a picture of the filter media. Maybe that's when
something got into the seal and worked it's way under the O-ring.. Before I took that photo, everything was fine!
Thanks for that tip! "and seem like the air is coming from the QD." That helped a lot!

Rich

Still working my way through all the posts in this thread - but as I've seen these small compressors as per original post advertised as up to 500cc bottle only and also seen same compressor 7 liter fill time on other ads - I'm wondering if anybody has tried radiator cooling to enable the filling of scuba tanks
I wonder about these mini radiators with fans:

Radiator cooling has been done somebody did post a picture of it somewhere in GTA. You just have to look for that thread.

What is the max size tank that these compressors can be realistically used to fill ?
Can they do scba 66cf 88cf ?
or more for the little ones ?
They are for paintball tanks, which I believe are usually 0.4 liter and buddy bottles used on air rifles typically 0.5 liter
If you fill a bigger tank in stages I see no problem - UK supplier to Amazon UK states the maximum bottle size is 0.5 liter 300 bar - I suppose that's what they calculate is safe for continuous use without over-heating compressor
-
Ken,
What is a 144 CC tank? That seems tiny to me since a 13ci ninja is 213cc.
I'm considering one of these to top off my scuba after each shooting session (3000 PSI 80 CF, maybe ~200 psi top off) but if it takes an hour to fill a bottle half the size of a ninja bottle, that might not be quite enough....
Definitely not 144cc - if it is metric measurement on the tank then more like 14.4 liter - maybe marking is 144?
-
Bet there is an omega air compressor on the web under a different name, color?😳
And the link to it is?
this one which looks just like my omega but different color. no price😳😎
link removed
There is a price now - $800 but minimum order is 10 units, so $8000 dollars investment - don't know what the shipping cost is
Looks like Omega latest version - except the controls for self-draining are missing - just a blanking plate - guess it is pre-set intervals
-
Have a minor problem with the gauge. Needle is bouncing around and when I bleed the system from filling sometimes the gauge will not return back to zero. Have to tap the gauge to make the needle go back to zero.the needle Reads 10 psi off from zero and I have to tap the gauge to get needle to zero. I'm going to have to get a new gauge that is liquid filled. I believe the liquid filled gauge will help with the vibration of the compressor while filling. The gauge still works but due to the vibration the gauge is not accurate any more.
I did watch an unboxing/demo/teardown video that said they cannot ship these compressors with batteries or any oil - including oil in the gauge - and that you are supposed to add silicone oil to the gauge yourself before operating - pretty sure it was that big German youtube guy - called Spraug or something - does slingshot, crossbow and air weapon videos
-
Hummm, I just noticed. Your gauge is not glycerin filled? Mine is... Maybe they didn't use filled gauges in the early production models? Or, did yours maybe leak?
They are not supposed to ship anything with oil in it - including gauges - you are supposed to add your own silicone oil
-
This is true.... I hear folks complain about items coming to the US without batteries.... well, they're not supposed to have batteries in them. Lots of legal stuff goes into International shipping, including higher rates for shipping hazardous materials. Batteries are caustic among other things.
-
I'm surprised that nobody has fabricated a self-contained liquid cooling option (Radiator, fan, reservoir, tubing, fittings, aluminum mount, propylene glycol/distilled water mix, and a 12v out to Molex) . I've built plenty of computers with them.
Could be done and would work - but would require some sort of automation - start, stop, vent, start, stop, vent, until filling completed - similar to how a refrigerant dehumidifier works
I've now convinced myself that these compressors are not suitable for anything other than topping up air rifles - the twin cylinder compressors are much better - the one I've got my eye on has been sold previously on Amazon under the DAVV brand name - but now only available from AliExpress type sites
-
I got the name wrong on the type of compressor I'm now looking at - looks like DAVV painted on the compressor but is actually DAVY
These are now listed as unavailable on Amazon - were $800 or more
Not sure about the supplier reputation but several on AliExpress less than $450 delivered
Looks very similar to the twice the price "in a frame" compressors

I've been unsuitably topping off my 80cf scuba ever since I received my compressor.... Makes 50psi/minute, even after running 20 minutes it never got above 55c with a 5 gallon bucket of water. Personally, I could ask for no more for $327 to my door.

Yes, I know it can be done - but they were not designed for it
The supplier to Amazon UK state max 0.5 liter tank for the single cylinder compressor and 6.8 liter tank for twin cylinder compressor - your tank is about 12 liter - I know you are just topping up but still way over what a single cylinder compressor is meant for - seems a lot of people's compressors would overheat badly, doing what you are doing
-
It appears that the cheapo twin cylinder compressors on AliExpress that I like are knock-offs of DAVY - which have all black cylinders - cheapo ones are bright aluminum, so I don't know who are making them

I hear a lot of people (yourself included) that don't own and have never actually seen one of these compressors in person state that these can't and or won't and or shouldn't fill scuba tanks. To many, that means that these are automatically not an option for anything except topping off guns and they immediately feel they need to move on to much larger and or more expensive machines when most of the time they would simply be topping off cylinders also.
If you were filling from zero, and if you didn't ice your 5 gallon water jug and if you didn't do maintenance then bad things can and do happen as we've seen (though so far it seems to be Tuxing brand compressors that have had the reported afflictions, but the reports I've seen on those failures was less than scientific).
I know I am not the only one successfully topping off scuba tanks, and many have been doing it MUCH longer than I have, but I can assure you that I and anyone else who is "testing" these little compressors would immediately report a failure because everyone (including many of us who bought them) is chomping at the bit to determine the MTBF in as many different use case scenarios as we can dream up because they seem too cheap.
Also, I see many assume because they paid upwards of $1000 for an air compressor, that it must be better than the cheaper compressors. While this may be true, at the end of the day you are still buying a chinese air compressor from a chinese manufacturer that may or may not provide support in 2 years, and may or may not supply parts in 2 years and may or may not still work in 2 years.
Eventually every mechanical thing will wear out and require parts and it doesn't care how much cash you piled up for it when you swiped your card. The fact is we don't have enough history on any of them to determine what their lifespan is nor what the weak point is that potentially all of these compressors from the $1300 carette down to the $300 yong heng all share.
-
Guy on YouTube did a review and said the pump is fine no real issues. You need an external water supply for cooling

Shorty true story. I am a collector of switchblades and out the front (otf) balisong ( butterfly) knives since childhood. (Military gave out the gerber and h&k otf and switchblades)high end knives such As microtech gerber h&k etc. found a website China of course that sells exact copies of the mention knives right down to the packaging 😳 so I ordered theses knives and a month later, they arrived in the mail. I was shocked to see how the Chinese copied with great detail down to the weight packaging side by side had to write a c on the box to be able to tell the copy vs the real one😳 I call the microtech manufacturer and was told yes they are aware of the fakes because they get the fakes in for warrenty work and they can tell some way that it is not the real deal and the customer does not get the knife back. Microtech will not ship overseas to customers because of this problem. When it comes to the high end compressor davvy etc in my opinion, I truly believe that the compressors are made in China with the manufacturer label shipped to the factory and selling at a high price😎
-
ALL need some sort of cooling. If I didn't accidently luck into the dual cylinder compressor that I have, I would have one of these single cylinder ones. I would have probably joined the "I got burned" club at least once and may even be still waiting for my refund. But at the end of the day I would have one of these smaller Chinese compressors. For no other reason but it's what I am willing to invest in this part of my hobby..... key word being "hobby". It would be at that point that I would make my decision as to how I chose to use it. Whether directly filling guns, filling my 80 and 100 cf scuba tanks or investing in a smaller capacity larger psi carbon "buddy type" tank. The thing is, the compressor is so portable and so efficient for filling guns directly I doubt I'd be filling larger tanks regularly unless I'm spending a whole day or 2 in a remote location. With a bit of common sense I could see these compressors as very useful and dependable. I can get from point A to B on a moped or a Harley. I am fortunate enough to have the Harley. If not, I might be sporting a scooter. I see folks going down the road on a scooter with the same grin I get from my Harley. I'm pretty sure they do the same basic maintenance as I do to insure they get there and back.
-
Excellent point on the buddy bottle Bill; I hadn't even considered one before, now I'm thinking that might be the perfect compliment to my compressor and much easier to cart around. If I need more air than that, it is certainly easy enough to just take the compressor and a bucket with a lid....
-
I followed this string a very long time before opting for the Carette compressor from airtanksforsale and their alpha filter. I like that it is completely self contained..no need for external cooling tank. I am more than happy with my set up. I believe the cost associated with going this route over the less expensive unit will pay off in the long run. There are several guns that I didnt buy while saving for this and I appreciate what I do have more. Overall well worth it
I'm tempted to buy one as well - just want one direct from China to UK at a low price, rather than through USA distributor at high price - I did find one, but not confident about the site I found it on
-
Heck, I can't even find the Kalite/Carette manufacture website.....
Neither can I
Direct from factory to UK would be best
I did read in the blurb that it stays cool because it has slow motor speed - could that be why the cheapo compressors have over-heating problems - motor spinning too fast for fills over the recommended 0.5 liter max bottle without stop and cool off periods
-
Yep, point being... if I go away from home to say, my sister's for the weekend, I would just take the little compressor. If I went for primitive camping/hunting for the weekend... the buddy bottle would be the way for me. I don't do that often enough to stress "the little compressor that could".
Here's another scenario... I see some of you doing the sealed radiator/fan setup. Personally, I would use that setup for filling guns only depending on the radiator capacity. I might even bump up the radiator capacity and mount the whole system in a small yard wagon. Heck, you could mount it to a two-wheeled dolly (hand truck) for that matter. I think a major factor for me would be water separation. I live in a very humid area (Southern Alabama). My compressor now resides in a climate controlled environment and I still squeeze a lot of moisture out of the air.

Yes, I agree that you can get carried away - I now want a Carette, and would buy one if it was not for price gouging in Europe + 20 percent sales tax (looking for one from China)
There is a lot of conflicting information - Omega looked good until I read the compressor is basically a motorized hand pump
I have definitely ruled out the single cylinder compressors - twin cylinder is what I want - I can get one for $421 delivered to UK - quality will be same as single cylinder compressors but better design
-
If I didn't accidently luck into the dual cylinder compressor that I have, I would have one of these single cylinder ones.
I'm getting a knock off of the one you've got (without the frame) if I can't source a carette from China
I know about Chinese stuff - I've got the best Chinese motorcycle that's made, and it's got the best Chinese engine that's made - can it compete with South Korean bikes out on the open road ... *(&^ no, is it OK for running around locally ... yes
I thought you were a Harley rider as soon as you said you had a wrist injury
-
One thing to realize about the Davy twin cylinder compressor is that its only a two cylinder compressor just as the Yong Hengs are just setup as a V style cylinder arrangement. The black cylinder below the aluminum high pressure cylinder is just along for the ride since no air lines connected to it and there are likely no rings on the lower piston of the aluminum cylinder so it makes no compressed air.
The large finned cylinder that has the line going to the top of the aluminum cylinder is the first stage of compression and is directed into the top of the aluminum ( second stage ) cylinder to be compressed and directed to the adapter block with the bleed, HPA hose and HPA inlet from second stage.
In actual truth the cylinder arrangement for the second stage of the compressor is the same Yong Heng single cylinder setup with the lower stage non operational and just along for the ride. The fact it does not turn as fast as the YH compressor is likely due to the first stage cylinder on this one being a bit larger in CCs so it makes more pressure than the YH at a slower RPM.
Most all of these type compressor are modified and improved using lots of the same parts in different designs and configurations.

That would be my vote as well. I have a 5gal covered bucket for cooling. I keep 4 gallons of water in it and a 1 gallon jug frozen in the freezer. I simply drop the frozen jug in the bucket when running and return it to the freezer when done. I have the gold separator and the black one from MRodair both inline between compressor and tank/gun. The only thing I have yet to do is add red food dye to the water so I can verify water circulation.
-

Yes - but it's the separation that I'm willing to pay more for - less heat transfer to second stage - and I could easily make a longer transfer tube to aid cooling like they do with the Carette
If I could source a 300 bar head unit I'd make my own compressor with an external motor and gear the rpm to a slower speed - I now believe its the high running speed generating the excess heat
-
Right, I think I've solved the mystery of the conflicting mine gets hot/mine is running OK reports of Yong Heng compressors
There is a standard model with 2 metal pipes on the heads rated at 40 liters a minute
The next cheapest is the hardback model with 3 metal pipes on the heads rated at 50 liters a minute
The other 2 other more expensive still are the same as hardback except auto-stop and set pressure additions
It also explains why the supplier to Amazon UK says maximum fill is 0.5 liter - they only supply the standard model
I can see no other explanation for some people being able to fill large tanks to 300 bar in one go by just putting a gallon of ice in the bucket
So I've done a U-turn and think a Hardback 3 pipe Yong Heng is a good purchase choice rather than an unknown quality twin cylinder compressor
-
I believe most all of us with the Yong hangs all have the same 3 exterior pipe model. I don't think there's any mystery of why some run hotter than others. Not everyone is comparing with same volume of water and or ice.

Yeah, too bad it wasn't that simple! I know some with even the set pressure model were getting pretty warm. Did anyone else see when on the slingshot channel he took the pump apart that he mentioned his water line was partly plugged and he had to do something to drill it out or something? Am I remembering wrong on this? Sure that is what he said. Thought it was weird at the time. I'll have to check it again.
-
Ah, still weird but it was something in the compressor he drilled out, not the water line, lol. 😊 Whoops!

I've taken the plunge and ordered a Yong Heng compressor from China
I ordered the adjustable auto stop unit, as I did not want to take the risk of them shipping the low capacity version by mistake - if it has adjustable auto stop then it must be the high capacity version
I'm going to make a permanent set-up using a free standing tiered rack/shelving unit with a re-circulating water container - water coolant additive but no ice
I studied a youtube video of a guy filling a 10 liter tank to 2000 psi from empty in a 1 hour continuous run - temperature display showed 49.5 - he was dumping the water down the drain and not re-circulating
He used an infrared temperature reader on the oil sump/crank housing and it read 49.0
He then read the second stage housing temperature at 32.6
So, are we all misdirected in cooling the water? - maybe we should be cooling the oil sump/crank housing - or could it be what is being put in the oil sump?

I see a bunch of these compressors on eBay now for $299 and change shipped. They are all shipped from Onterio, CA and claim delivery in a week. There are about 7-8 different vendors, but all the listings say the exact same thing, so I wonder if it’s really just one vendor with multiple eBay accounts. The difference is price is less than a dollar, and some of the vendors have higher (5 digit) feedback counts with ratings between 95% and 97%. They all are offering Best Offer, and according to the feedback I saw, some are accepting offers.
These compressors have no name in them, but they appear to the the two stage hardback models with the cyclone oil/water separator. I said I’d never purchase one of these off eBay after the last fiasco, but I’m now considering making an offer and see what happens. Has anyone one else here purchased one of the $299 compressors?

YES ^^^^^
both times i got COINED there was no-name on the side other than "air-pump" :o
when i finally got one, it was a genuine YH....said it on both sides !!

Third vote here for not buying one with no name.
I'd just spend the $327 and know what you're getting. The best part of having one of these, is you quit looking for deals on them. LOL ;D
-
Yep... I think if I was going to buy one right now I would spend the few extra bucks and get this one.

The longer you look, the more chance of you buying something expensive
I started looking at Yong Heng and ended up looking at Carette - would have bought one too if it was not for EU distributor trying to price gouge me - even without the dreaded 20 percent sales tax it was considerably more expensive than USA distributor charges

You made the same circle we all made, you just happened to do it publicly, through this thread, while most of us made the circle privately while driving or before we went to sleep. LOL.
I personally feel like my little Yong Heng punches above it's weight. I am pleasantly surprised with it's performance thus far.

My last word on overheating Yong Heng compressors (maybe)
If I do get overheating problems due to re-circulating the water, I have a solution
An old 4 cu ft refrigerator that died and has since just been used for storage, has on its back a 14x19 inch copper tubed condenser complete with cooling fins - tubing is quarter inch outside diameter - should be perfect radiator and cost nothing

Yeah, I've been eyeing that one, even have it in my cart... Just can't bring myself to click buy yet... I guess with the recent price drop on eBay, I'm hoping it will carry over to Aliexpress also!
-
I think I would avoid drastic price drops. Many have been down that road. At least one scammer was very successful which makes it attractive for others to give it a try. In my opinion, $330ish is not a bad price to pay for one of these units that include the auto shut off, reasonable delivery time and some good buyer reviews. I would still contact the seller and ask some questions just to "feel him out" before committing. I would not depend on Ebay and Paypal having my back.

I still say the high end one that Mike sells at Mrodair is a fantastic deal, buying something like that I'd be all said and done with it pretty much and just use it.

Jay, maybe you should read this thread again. There ARE folks that have not gotten their money back. I'm sure you'll see shortly.
-
I agree with Bill, there is a member here who is still fighting PayPal because they decided against him on this last eBay Compressor scam. I also have a college who purchased one of the $200 compressors, went through all the same steps I did, and eBay just notified him last week that they were not going to refund his money. I was one of the lucky ones, and did get my refund, but it has really soured me on eBay, and probably more specifically, doing business with China through eBay! With just two people I know of personally, that have not received a refund after falling victim to a scam eBay and PayPal had to have know existed (based on the number of folks here taken by it), yet they refused refunds to a couple. That in and of itself raises the risk for me considerably!
-
I will add that I have not been burned personally by Ebay or Paypal. I will continue to use them, just not for a Chinese air compressor.
-
That's good to know Paul, about your colleague getting burnt by eBay. The other buyer having trouble with PayPal unfortunately didn't have a PayPal account and didn't realize if you simply use PayPal as a screen to hide your credit card number from the seller you don't have any purchase protection. You need a PayPal account. This is something PayPal should make more clear, but other than that they can't really be blamed. At least this is my understanding of what the seller lately disclosed about the case. I wonder if he could still file a claim with ebay? That is troubling to hear eBay decided against your friend. They obviously know these sellers are crooks.

Ahh... got ya.
Not what I meant. I see what you mean. What I mean is..
The scam has been with these darn Chinese compressors that were bought through Ebay from pretty much the same fake vendor. He seems to have changed his name around a bit but it is obvious it was the same clown. Many caught on, some did not. Ebay and Paypal were good to take care of the issue in the beginning. Where they failed was by not pulling the vendor. Then to make matters worse they dumped on the remaining customers leaving them to turn to other means of trying to recover. I wouldn't be surprised if the vendor is still out there. Or someone else is taking his place. This is why I would not buy the Chinese compressor through Ebay using Paypal based on low price. I still want one of these small portable compressors even if I pay a few more bucks and get it from a reputable source. I may even use my Paypal account. Like was stated earlier, it's a good idea to have an established account. Mine is linked to a debit card through my bank. If the money is not ear marked, nobody is getting it. Now I have my bank, MasterCard and Paypal between me and the scammer whom Ebay seems to be sympathetic to.
-
I bought one of the Yong Heng compressors from aliexpress and so far so good.Got the 110volt set pressure version,it gets a bit hot so i put ice or ice water in the water with the pump
-
... and the scammer whom Ebay seems to be sympathetic to.
ebay and paypal lost a good bit of money due to the scamming and decided to balk on returning money to the last customers getting ripped off. (so ebay/paypal wouldn't lose even more money)
At least that is what appears to have happened.
And if so, ebay's and paypal's reputation has been reduced to not being trustworthy, at least not in all circumstances.
But each person has to decide if they want to roll the dice....regardless of how many years/ purchases they have made through them.

The Yong Heng compressor I ordered from CHON Electronic Technology Co., Ltd. via AliExpress 2 days ago is at the TNT depot at the airport
TNT tracking says they'll deliver it to my door in UK in 6 days time
So, if no problems, only 8 days from ordering it to getting it delivered :D
-
I have a brand new one sitting in my floor that is the top of the line version. I used it one time and had to send my gun back. I might sell it, I don't know. Works great.
-
You don't have other guns to fill with it? I see you have a carbon fiber tank.
-
Does anyone know if it's possible to upgrade the 110v simple version of the compressor to the 110v hardcover model? I purchased the cheaper model before I knew the difference between the two. :( I would really like to have that low side to drain water from. Thanks!

The simple versions works fine. Just use it to directly fill your guns instead of filling large tanks. If you search Aliexpress and contact the manufacturer you may be able to get an upgrade kit if they even sell one.

I agree, I have the simple version and it does a great job at filling all my air guns. I also have a 90ci carbon fiber tank and may try filling it also, but for now it will fill any air rifle I have in under a minute!

Yep, it was a long road, but it finally worked out! It's amazing how fast these things fill an air gun!
-
I have an auto drain/auto shutoff Tuxing 220V running off a transformer that I use to fill my guns directly (3k max for all that I currently have). It has worked very well for me but eliminating the transformer would simplify things. I don't need to use either "feature" because as has been noted it fills a rifle so quickly that you don't really need that. I also have a YH 110V that I got for $305 to use as a backup and I purchased it without those "features" because of that quick fill rate. If I ever buy a large tank I would probably get a better type compressor. I do wonder if that quick fill time might also keep some of the moisture out of the air that many work so hard to eliminate. I don't think I would use one to fill a large tank but for filling a rifle directly it has worked great (so far).

Speed doesn't reduce the relative humidity thats in the air.

Thus the reason mine is indoors where temperature and humidity are regulated! I'm still going to invest in one of the larger oil/water filters just to be safe... Living in Florida, my house A/C can only do so much!
-
I was thinking of additional run time/heat possibly raising moisture/oil levels in the compressed air. I use mine in an air conditioned room precisely for the reasons mentioned. Noticeable moisture has not been detected in any guns I have filled directly (pp700, SPA M10 and Varmint), even when using only the small cotton filter. I have a Diablo filter with dessicant now but used the smaller filter only for a time before getting that. And yes, the air tubes have been off both the pp700 and M10 and checked visually with no noticeable moisture seen. Maybe it is due entirely to the A/C but it would seem to be possible that longer run times and higher temps could result in more contaminants entering the air.

As our outdoor shooting season is about to begin, it is time for me to do a top end rebuild. For those of you that didn’t know, I ran my compressor without water last summer. Though the compressor still worked fine, I have decided to just replace the top end cylinder piston. I’ll report back this weekend on the outcome. Should be an easy swap😳

🧠 fart😳 I now use a power strip and use the on/ off switch. That a way I won’t forget to plug in the water pump. Got spoiled using the omega compressor before buying this yong heng. Bought this compressor for it portability and the price point. Has proven to be a reliable compressor despite it overheating is still pumping air😎. Just doing maintenance on her and curiosity 😎
-

Do you have a young heng? Will do on the pictures 😎👍🏾
-
The above is one thing I like better about the Tuxing version of these compressors-the water pump plugs into the side of the compressor itself. If you leave it plugged in then anytime the compressor has power connected the water pump runs regardless of whether the compressor is turned on with the switch. Not a major deal but it is a bit more convenient.
-
I don't have a yong heng but it looks very similar except the second stage piston doesn't look as well made. So if/when it quits I may try to fit YH parts to make it easier to fix with all the info out there.

Ken, these things are so easy to dis-assemble it's almost funny. I thought they must be super high tech to make 4500psi but it turns out that it is a dead simple design. I had to strip mine down and clean it out when I got it because the company that shipped it (located in CA) puts oil in them and tests them before shipping and mine was sent upside down so the top was filled with oil (they did drain the oil but didn't get it all out obviously). :o No bueno! They gave me a $100 refund so I ended up with a good little compressor for $200. ;)
-
Pics of the topend rebuild on the yong heng. For the most part very easy to rebuild the compressor. Compressor is back to 100%. 😎 just have to remember to plug in the water pump.
-
Ken, nice write up on your rebuild. I purchased my compressor together with spare parts one year ago and it has not failed yet.
I have been keeping track of the fill times and it is still going strong. Last summer it as used continuously to keep my grandsons happy.
-
its amazing that these little units do so well and all re-build parts are available.at first they were all going to blow up killing air gunners,breaking down and have no support.the cheap Chinese compressor that can pump rifles in 35 seconds.
-
Ken, did you find any fatigue from when you ran it hot ??
i dont see any discoloration but, i cant see no good either ::)
-
Bob, how many hours run time do you think you have on the compressor?

Bob, if it wasn’t for the compressor overheating, this write up wouldn’t be happening and now I know how the compressor works internally so it a win win for me and others to learn by😎 I was the guniea pig when I first posted this thread buying this compressor and now posting the rebuild of this compressor. 😳 btw would buy another young heng if for some reason I need to😎. I think this compressor is that good because I bought another yong heng while in the Philippines 😎
-
Thanks for posting pictures of your rebuild. Mine looks very similar inside (which isn't surprising). Now I want to buy a YH piston just to try it ;D
-
Do you guys leave your water hoses hooked up even if you aren't going to run the compressor for a few days? I can't see it hurting anything?
-
I have left mine for quite a few days but it can get some biofilm started after a while. Probably would not hurt anything.
-
Ken, did you find any fatigue from when you ran it hot ??

John no fatigue or discoloration on the parts. What failed was the second stage of the compressor. Pictured is the piston with a shaft I used a letter opener as a pointer to show everyone that 2 of 3 o-rings where broken / brittle from I’m guessing when it overheated. The good thing about this compressor is the o-rings are already included with the spare parts that come with the compressor for a one time rebuild if it came to that. There isn’t much info on what the o-rings fit😳 I will take a picture of the o-rings so everyone will know what the o-rings look like hope this info helps those who have this compressor that may need this info in the future😎

Does it look like the second stage rings would be difficult to take off and change? From what I could see, you changed the complete head unit with pistons, correct?

Still have the original topend. Replaced it with a brand new topend for $88. Didn’t know what the o-rings went to until I open up the topend is when I foutout that there is a complete topend rebuild kit with the compressor. I personally haven’t tried to replace the new o-rings but plan on rebuilding the original topend with the o-rings. Will post how the o-rings replacement goes.
-
Thanks, really interested in seeing how hard it is to replace the second stage piston rings.
-
Ditto on what Bob said Ken. If I do get me one of them Yong Hengs I'll be baby sitting it when I first get it. A lot of the people are also getting the non auto stop one's too. They don't cost as much without but if you're just filling a gun it won't take long anyway.
-
I got my Vevo compressor on ebay for $281 with free shipping shipped from Ontario, CA. Looks pretty much like the Yong Heng compressors but it is 40 Mpa not 30 Mpa. I am still learning it at this point. The manual is seriously lacking. I bought compressor oil at Harbor Freight for $4.57 for a 32 ounce bottle.
Ok folks I drop the dime , ordered one from AliExpress. I ordered the 110 volt. I hope the water pump is 110 volt, otherwise I will have to go to chinamart pet section and buy a pump? The compressor $160 and some change. Shipping $144 and some change. I click on buy it now and the price jumped to $179 and some change. Got the discount coupon $4 and the total shipped was $ 324 and some change. I hope the compressor is package well for the journey across the pond. I will have to wait to open the box after April 5 and test review this littleness compressor. In the mean time bh1976 I await your test results as do our audience 😎
-
Seems like it was going to last forever. This morning I attempted to top-off the PRod and it failed. One side of the DPDT off-on switch has a bad contact..
I could jury-rig a switch, but I found a Holtsville, New York EBayer that had one switch left in stock. It looks like it might fit..
-
Yep, I fried the switch on my Vevor and borrowed the one from my MKII while it waiting for a high side seal replacement. I'll order a couple and keep a spare.
-
Ken did you ever replace your top end rings? I did mine a few months back and it was a major PITA! Just wondering how someone else went about it. I had to soak my rings in almost boiling water to get them to stretch enough to get them on the piston. Then ended up using a fuel line quick disconnect tool as a ring compressor to get them to slide into the head.

Ditto did the same thing. Still on its first rebuild since I burn up my compressor by forgetting to turn on the water pump. Now I use see thru water flow wheel that spins. Plug both into a power strip that I turn on so both come on at the same time and I watch the flow wheel spin as well as the temp gauge. I have had the water pump quit working on me and the only way I knew was by watching the temp go up hence the water flow wheel 😎

Then ended up using a fuel line quick disconnect tool as a ring compressor to get them to slide into the head.
I bought the shaft with the rings already on it and just replaced the whole thing!
Ditto did the same thing. Still on its first rebuild since I burn up my compressor by forgetting to turn on the water pump. Now I use see thru water flow wheel that spins. Plug both into a power strip that I turn on so both come on at the same time and I watch the flow wheel spin as well as the temp gauge. I have had the water pump quit working on me and the only way I knew was by watching the temp go up hence the water flow wheel 😎
Hopefully I won't have to replace the rings again for a while. I think next time I will just buy the assembly with them already installed. Mine was never overheated. I had developed a leak on a fitting on the hose coming off my gold filter. Thought it was the compressor at first. Didn't discover the leak until after I had replaced the rings.

I got the switches (two pack) and they are the exact replacement. It's weird getting over-night delivery from Ebay. Never saw Bluecare Express before.
Maybe Amazon has an Ebay store outlet & sheath delivery now. There was an Amazon.com receipt in the bag.
Humm, yeah, the store also sells on Amazon.. https://www.amazon.com/Baomain-SOKEN-Light-Rocker-Switch/dp/B01LT3F5B0 (https://www.amazon.com/Baomain-SOKEN-Light-Rocker-Switch/dp/B01LT3F5B0)
I could have saved a little money, but it would have been 3 day delivery. I could have really saved money by waiting for a boat from China! LOL..
Anyways, the air I had left in the PRod was enough to deal with the varmints for 24 hours without a compressor. Back up at 3,000 PSI again! :)
The new switch has a light inside, my old one must have been bad, since it was never illuminated.
Cheers,
Rich ;D
