I have been calling my compressor a yong heng but it appears to be some sort of clone maybe? Looks alot like the yong heng with a few major differences. Obviously no Yong Heng written on the side, the small hose filter is a bit different, the burst disk sits directly on top of the second stage, water hose connectors are different and the major difference is on the inside. Mine doesn't have o rings on the second stage, it is some sort of plastic bushing which I'm sure will be a nightmare to find a replacement for when this one wears out. May have to just see if someone can make me some?
I can't complain really because the ad that I bought it from called it a Vevor compressor but the picture they showed WAS a yong heng. Another member here bought a Vevor compressor from the same seller and said he actually received a yong heng. Thats what I was really hoping for but no big deal as long as it works. He did say that his came with a small amount of oil in it as well so I'm thinking that they test them before shipping and can't drain ALL of the oil out. Mine just happened to spend most of its time upside down which gunked up the top end.
Has anybody else seen a compressor like this one? I am a bit concerned as all the reviews showing the yong heng as a safe little compressor mean nothing now. Who knows if this thing will hold up under the kind of use the yong hengs do? I will be filling to 3500psi for awhile to play it safe.
I'll be happy if it lasts me the summer and then I'll either get a REAL YH or maybe the AV Nomad from pyramyd air (if reviews look good).

The same seller appears to sell these on ebay under a few different accounts? They all say they ship from Ontario, California (where mine came from). Can't imagine there are four companies in that one town that all sell these compressors! I can't figure this ebay, amazon chinese mess out lol.
-
Heck it just filled my gun from 2000-3500psi in maybe 35 seconds. There's no turning back now....
-
They do make quick work of filling guns. With just the small filter mine will fill my Hatsan under a minute. With the gold filter its closer to 2 minutes.
-
Yes I'm going to like this ;D
Do you use the beads in the gold filter?
-
No I'm just using the cotton filters. I added an hour meter. I swapped them out at 2 hours. I also had changed them once before I added the hour meter. They were a little damp when I swapped them. I will check them again when I get to 4 hours of run time. I added the hour meter back in October. I wish I would have added the meter when I first got it last May so I knew the total run time it has on it.
-
Thanks, I will be ordering the gold filter but probably doing the molecular sieve mod to try to keep as much moisture out as possible. Honestly after seeing the second stage plastic ring I'm not expecting this thing to last that long. Who knows maybe I'm wrong. I am going to ask the seller if he has spare pistons available...
Already pretty much decided to get the AV Nomad when it comes out in May. I like that it is air cooled and a lot more portable than this one.

Made a discovery! Mine appears to be very similar to the Ace Eagle compressor. Chon electronics sells spare second stage piston rings, gonna order a complete rebuild kit to have on hand

Thats the same place I bought my Yong Heng and gold filter from.
-
I have a Tuxing working for quite a while now which is functionally about the same as the YH. I woke up early this morning and decided to try to top off the Great White tank from 3800 to 4500. Had a small leak at the head from the soft water line-simple clip of the end section and back to business (probably hardened from the heat off the head but might want to watch that area). Took about 2 minutes to pressurize the YH small filter and the Diablo filter (I have them in-line) to 3800 and then about 6 minutes to go from 3800 to 4000 PSI in the 97cf tank with temperature reaching just over 45C indicated. Had to stop for a while but that fill rate for that pressure and tank volume doesn't seem too bad. Filling my guns directly to 3000 has always been a 1 or 2 minute affair with the YH filter only but does take about a minute longer with the Diablo in line. Not bad for the cost but longevity is uncertain. I'll continue later in the morning when time allows.
-
The Tuxing looks like a good little compressor. I read wingmans review and it looks just as good as the yong hengs.
Hmm I wonder if a yong heng piston would fit in my compressor?
-
Just a guess but from the visual similarities of all these compressors I bet the parts would interchange. I did fill the 97cf tank to 4300 later in the morning-it took about 10 minutes from 4000 to 4300 at which point the Diablo o-ring started to leak and I had to stop. Not a bad fill rate for that pressure and volume of air.
-
i just got one just like yours delivered fri, i have the gauge with the auto cut off, but the piping is the same style it looks like design changes in the last year for it was not as pictured in add, but seems solid, will definately be going for upgrading the filter
-
Does yours have the blue filter like mine too? I bought mine from walmart for $299 and didn't see the auto shut off model. I wish I would have found one though because I can see the benefit.
I used mine a few times today, it seems to work just fine for filling my gun up. Super quick from 2000-3500psi (350cc bottle)
-
My god does the air that comes out of these things stink though! Can't wait to get some extra filtration to try to cut down on the stank lol.
I never want to smell hot compressor oil again in my life. Its so bad that I have to hold a ballistol soaked rag over my nose to mask the stench, thats when you KNOW its bad! I need some oil that smells like, leather, dryer sheets or even strawberries ;D
-
Maybe wrap a dryer sheet around the breather? I知 guessing putting scents into the oil would mess up the lubricicity and possibly add detonation causing ingredients.

the filter on mine is gold but the same size, i was thinking of putting the molecular sieve in there, and maybe getting a better intake filter setup
i will see if there is a shutoff gauge i can find you, seems it is just wired into the switch easy enough and you would just probably replace the gauge and wire it in. mine came with a 220v tag and 110v plug, they said the us models are sent with 110v setup but i feel i should just make sure before i f it up
-
I would verify the voltage on that compressor. The Chinese 220v plug is the same as the US 110v plug-I'm looking at one right now. Be sure of the voltage or you may burn out the motor.
-

I was only joking, I'll deal with the smell if it means I dont have to use a hand pump!

Yeah like bandg said I would make sure it is 110v. Mine has a white sticker on it that says 110v

Yeah I know to be worried tags and all, didn't know the Chinese 220 was the same as our 110, that makes me more concerned for others who might not be as cautious
-
Oh yeah thanks for confirming that, good looking out that's what I like about gta
-
Have you tried it yet? It sure beats hand pumping but the water is a pain to deal with I think but Im just complaining. Sure wish I had a nice spot next to a deep sink where I could leave it hooked up. Just turn the faucet on and go
-
"Relatively easy" way to handle cooling water for YH (or Tuxing)-go to Lowes and buy a Husky plastic locking tool box for about $12. The one I bought is 8"W x 15"L x 8"H. Drill a couple of holes on the top lip, just under where the lid closes, and just smaller in diameter than the tubing supplied for coolant flow and notch the lid edge so you don't pinch the lines. Pass the hoses through the holes, glue the pump to the bottom of the tool box and attach the hoses. I used finger turn hose clamps from auto parts store to attach the hoses to the pump head. I can fill the box with ice/water to run the compressor then pour the water easily into any transfer bucket to empty or you could detach the hoses from the pump head and carry the entire rig to the nearest sink. I leave the return line suspended just above the water surface so that I can SEE water flowing. Not nearly as convenient as an on-board reservoir for the larger compressors but it has worked pretty well for me for some time now.
-
well just straightened it out it was 220v, even the water pump was 220v with 110v plug, labels confirmed it and it did not move water at 110, replaced the plug wire, i got to get another water pump easy enough before using again, but it is a game changer, i just hope anyone who got one like mine figures it out, time to pester the company who sold it
-
Did it ship from Ontario, CA? If so I have been emailing them back and forth negotiating myself a discount because my compressor wouldn't run when I got it. They have answered all my emails and have offered me a discount (never take the first offer ;D ;D ;D)
-
yes it did come from ontario ca, Sanvin Corp is the main guy, the sellers are just repeated accounts so the flood the image overload sensors and confuse you with minor price changes, sorry to hear about yours going sour was it a voltage issue?
-
Yup sanvin corp is who I got mine from.
Not a voltage issue. There was oil in it when they shipped and it was carried upside down which filled the second stage with oil and kept the crank from turning. I disassembled it and cleaned it all out in a couple hours simple enough
Was wondering why I have seen 10 different sellers all from Ontario, CA lol
-
The water pump is one small thing I do like better about the Tuxing setup-it is plugged directly into the body of the unit and powers on any time the compressor is plugged in so you can't forget to switch it on. Glad the compressors are working for you. Sure beats a hand pump.
-
they gave me $100 back for my troubles with the compressor 8) So a compressor for $200 at this point, however long it lasts I'll be happy.
-
Good to hear they did right by you, I am still waiting to hear back from them
-
I have no experience with these pcp compressors but would you recommend one for personal use on filling pcp airguns and my small air venturie 90 cubic inch tank . How long would it take to fill my airforce 500cc tanks let's say from 1900 psi to 3000 psi ?
-
I would recommend you get an actual Yong Heng because the second stage piston appears better made compared to the one I have. That said mine works great also. It will fill my gun with a 350cc tank from 2000-3000psi in seconds literally under a minute.
For a 500cc tank from 2000 to 3000psi I would bet under 2 minutes
-
I just ordered one of these and I am expecting delivery Friday. I was wondering, might it be a good idea to fill the oil, run the compressor for an hour or so, then change the oil again? I thought that might capture a bunch of metal filings, get them out of the system, and extend the life of the system.
I have been calling my compressor a yong heng but it appears to be some sort of clone maybe? Looks alot like the yong heng with a few major differences. Obviously no Yong Heng written on the side, the small hose filter is a bit different, the burst disk sits directly on top of the second stage, water hose connectors are different and the major difference is on the inside.

Jim, I think thats a good idea. I noticed on mine that the first oil fill changed color pretty quickly. I changed mine the first time after only a few direct gun fills.
-
My god does the air that comes out of these things stink though! Can't wait to get some extra filtration to try to cut down on the stank lol.

Tweeter, the fact that your compressor got shipped upside down and with some residual oil in it indicates that oil seeped past the pistons. You'll probably have less oil smell after the residual oil burns off.
A friend of mine has an Air Venturi compressor that costs $1299. It puts out an oil smell while running and lots of white oil/water mix comes out of the moisture dump when he manually purges the moisture drain. All of the Yong Heng/Tuxing/Air Venturi direct drive compressors are pushed at high rpms to achieve their fill speed rates. A consequence is that they tend to burn oil. My Carette is belt driven at much lower rpms. It has a lower fill speed than even the Yong Heng/Tuxing mini compressors. The upside is that it never smells of oil, it doesn't even have high pressure piston rings, and it puts out about 1/3 the noise level and vibration of the others. I've run it for 10 hours beyond the first 5 hour oil change and the oil in the window hasn't darkened a bit.
-
Jim, it couldn't hurt to change the oil after a brief break in period. That is what I did with mine.
Humdinger, thanks that makes sense. It really isn't that bad honestly anyway ;)
-
so in the end the ebay co "Sanven" gave me $100 for my issues which covers my extra cost to have it looked at and rewired and to replace the water pump with the RIGID universal submersible water pump, it pushes 50g/hr or 18,927 L/hr, the pump that came with it is 550L/hr
-
Glad they gave you some money back. I was going to keep pushing the issue with mine to get more money back but decided to not get greedy ;)
If you read their return policy it states that YOU are responsible for return shipping so I didn't want them to say Ok, just send it back then lol. They were good to deal with.
Did your compressor arrive with a little oil in it?
-
Also be sure that your new submersible pump does a good job cooling. I've heard that if you use a pump that pushes the water too fast then it won't have time to cool the head.
I read that on the internet do it has to be true!
-
Mine came yesterday . Wish i had seen this thread before ordering , was expecting the normal yong heng just without the stickers and was freaking out when I opened this up and saw the differences . Ordered from bigvaluehotitem on ebay from Ontario CA . Oh well , we will see how it goes . Not going to run it till next week after the filter arrives , may tear it down this weekend and check out the innards while i wait . Ordered the big double filter , probably overkill but cant hurt . Thanks for posting the link to spares .
Couldn`t stand it . Just tore it down and found a free bonus screw loose in the crankcase and some rust in the head , glad i tore it apart now .

If by big double filter you mean the the twin gold filters from china your going to like them. I believe those will come with a stainless tube with screened end caps and o rings on one end to force air through filter and out other end. Air then travels around small space around stainless cylinder and out the whole in the side to the next filter. Sweet setup if those are the ones.
-
I believe I bought the exact same one as you. The ebay seller was ganfeii1_4 from Ontario, CA. The ad called it a Vevor but even some of the seller's photos showed Yong Heng on the side. When I received the compressor there were no brand markings at all. Also the ad stated it was a 0-30 Mpa compressor but when I received it, the "manual" says it was 0-40 Mpa compressor. A small sticker on the side says it is 0-30 Mpa. No matter as I currently own just one PCP, an Air-Ordinance SMG-22. After setting it up I had problems getting it up past 1000 psi until I discovered there was no Teflon washer in one of the connections. I put the washer in but also put Teflon tape on all the threaded connections and wrench tightened everything REALLY tight and that solved that problem. The second time I went to fill my 48 cubic inch bottle the compressor just went dead. Most people told me the relay went bad and that they are really cheap and known to fail but I got lucky when I found the reset switch on the relay and that solved that problem. So now it seems to be fine. BTW the so-called "manual" is useless but for less than $300 I'm pretty happy with it.

Zeddy. I believe that they test these comporessors before they ship which I suppose is a good thing as long as they drain all the oil out before shipping it.

That window oil view will not change color quickly accurately. My Carette after 6 hrs run,the window level color was gold color,but when you drain it, you will notice a metallic sheen on the oil. It's better to follow manufacturers recommendation on oil change interval .
-
Trigger_finger is right to remind us of that. The woil in the window isn't recirculated like the rest of it, it mostly just sits there. It's shielded from the rest of the crankcase by the rubber gasket. Every few hours of runtime is plenty safe once it's broken in, I think. If the oil in your window is discolored, the oil behind it is probably very dirty.

I just found this thread and am subscribing in hopes of learning something on these "clone" YH compressors.
I received one of these compressors from a friend who experienced similar issues as you all have described.
It has less than 60 seconds of run time on it and quit working.
The white label on it says 110v and it has the 110v plug. I have read through this thread and see that it has been said the chinese 220v power cord is the same as our (american) 110v power cord ?
When it is plugged into 110v, and I turn on the switch,... nothing happens. Yes the red light inside the switch is on, but the compressor does not run. No Hum, No buzz, No sounds or electrical smells of any kind.
Also, I notice the temp readout DOES read a temp, even with the unit NOT plugged in. apparently there must be a battery inside ?
I have read where some folks have had a relay burn up and needed to replace it... and I also read in this thread where a "reset" button was found on the relay.
I will remove the cover and check for this "reset button" in just a few minutes.
I just wanted to get into the thread conversation in hopes that maybe one of you have some ideas on what I may need to look for once I have the cover off.
I will return back here shortly, and report my findings once the cover is removed.
I guess my first question is,
Might it be possible that it is labeled as a 110v, but is actually a 220v ? And if that is so, then what would be the best way for me to determine or verify this ?
Thanks for any help and/or suggestions.
ok on edit-
I found the reset button and it was popped. I pushed it back in and hit the power button. Motor did make a humming sound, but did not spin. I cycled the power button a couple more times and it eventually did begin to spin. I only let it run for a couple of seconds and turned it back off. Then tried to run it again, and the motor would not spin, and popped the reset again. it would appear there is something causing the motor to bind up and not spin freely.
I will remove the cover again, and see if I can determine whether the "binding" is a mechanical debris in the motor itself,... or if is possibly a hydraulic issue with oil in the compressor piston.
-
BTW-
I just spoke with my friend who originally purchased it. The REASON he had concerns with it so quickly (after only 45 seconds of run time), was,...
1- it was not the Yong Heng model that he had actually ordered, and it did not match his existing YH compressor. (note the different plumbing pipes on the compressor cylinder), as comparred to the YH that is plumbed quite differently, and has the one pipe coming straight out of the top of the cylinder head.
2- when he did run it for the 45 seconds,... the heat rose at an alarming rate, and within seconds it was far hotter than his first YH compressor. (yes, the water was running prior to turning on the compressor)
FWIW, he had to open a dispute/case with ebay, before the seller (Sevan) would offer a refund.
He did also tell me that when he received it, there WAS some oil inside of the box, so that might indicate it spent some time upside down, and possibly has oil in the cylinder just like the OP found on his.
opening the cover back up now to see if there is some mechanical debris, and if none is found, I guess I will be opening up the cylinder head for an internal inspection.

Sounds like you are on the right path to me with your trouble shooting. Only thing I might have done before pulling head is to bypass the relay and try it to rule it out as a problem by connecting brown and green wires together, if the wiring is the same as on mine. Good news is these machines are simple in design and the parts are cheap and available. Good luck.
-
Oddly, this model of compressor does not have a relay inside in cover.
The power lines run through the resettable circuit breaker, and straight to the motor.

Gertrude,
I'm glad you found the reset button. For those who don't know where it is I am attaching a photo showing where it is on mine. Once you have the unit unplugged and the cover off, see if you can rotate the fan in the rear to see if something is bound up. Beyond that I have no suggestions because I have never had to go any further with mine. Mine tripped the reset the second time I filled my 48 cubic inch of a bottle but has been fine since. I have only about one hour run time on it so far though.

I guess the relays are only on the auto shutoff compressors then.
-
I am certainly no electrician, but it DOES have a cylidrical component inside that is about 2" in diameter, and approx 4.5" long.
it has some writing on it that says 250VAC 50/60 Hz. I will try to get some pics posted soon, but my Photobucket account is not playing nicely since they changed the PB rules.

Jim,
Yes my circuit breaker is in the same place as you show, but my compressor cylinder plumbing is the same as the OP's pics.
Yours looks more like the Yong Hengs I have seen more commonly.
-
I got the operating temperature way down on mine (from 60 to 30 degrees Celsius) when I discovered there was no Teflon washer on one side of the water filter and putting one in, putting Teflon tape on all the threaded connections on the high pressure hose, and wrench tightening the low pressure bleed valve.

Actually that picture was from the seller's ad, not the one I received. I just used it to illustrate where the reset button is on the units that have them. Here is my actual compressor. I bet it's more like yours.

Yes that's the component I was reffering to.
Is it some sort of capacitor or something that allows a 220v intended motor to run on 110v ?

Yup its the capacitor. Careful as I guess it stores energy and can give quite a shock even if the machine is unplugged and turned off ;)

Same as mine Jim, interested to hear how you like it. Mine has been running no problems after the initial debacle. I did add a thick oring on the low pressure bleed valve to hold it there when I turn on my compressor and give me enough time to screw it in. Otherwise it kept quickly falling out.

Ron,
So far I like it a lot though admittedly I have not given it a lot of use. I have only one pcp, a SMG-22 and I have only filled its 48 cubic bottle twice. That's a good idea about the o-ring on the low pressure bleed valve as I have the same problem with it.
-
I made sure I got a genuine Yong Heng - but all the different makes seem to be built from the same pool of parts
AliExpress Chinese retail website lists the spares for these type of air compressors - likely the parts were purchased from Alibabba Chinese website, which is the wholesale website owned by the same guy as Aliexpress
The picture in the original post looks suspiciously like a Tuxing variant - but who knows who made it
The second stage piston and seal is used in all of the variants unless I'm mistaken
-
Yes I think you are mistaken ;) The second stage piston on my compressor only has one seal and it looked to be attached from the top using a screw. From what I have seen, the YH second stage piston uses 3 seals (rings) that get slid over and into place. To be honest I'm not sure which is better or if they will work just the same. I will see how long mine last. I only fill my gun though so no large CF tanks.

Hey Guys,
I just thought I'd report back after getting a little run time on the compressor.
First, I do feel that the "binding" I was seeing (in about 90* of the motor's rotation), was probably due to a "tight spot" in the cylinder bore.
I set up a 5 gallon bucket of ice water, opened both of the vent screws, got the compressor running (without tripping the circuit breaker), and let it run for about an hour with no load/bottle hooked to the fill line. I closely watched the temp gauge and it never went over 53*c.
Next, I hooked up my 90 cu.in. Benjamin buddy bottle which I had bled down to 1400 psi.
I do not have a proper moisture filter yet, So I figured I would fill the bottle with it held upside-down, (valve pointing down), and would check for moisture after the fill. If necessary, after this "test fill", I am willing to bleed down the pressure, remove the valve from the bottle, and insure it it dry inside.
The compressor filled the buddy bottle from 1400 psi to 4800 psi in under 12 minutes.
Note - The reason I allowed it to go to 4800 psi, is because I wanted to see if the burst disk (in the head of the compressor), would blow somewhere around 4500, but I was not comfortable going any higher, so I do not know if the factory burst disk is really all that reliable as a safety component.
Once the bottle was filled, the temp still had not gone above 55*c, but remember, I was using ICE in the water as a additional protection for this long hard test-run.
OK, So it filled the little bottle fine, but it seems that when using only a 5 gallon bucket, it would probably be wise to use ice each time, to keep it cool enough.
Once the bottle was full and the compressor turned off, I closed the valve on the bottle and bled the high pressure side. There WAS a little bit of water discharge/spray, ... (certainly more than you would want in your gun), ... but not as much as I was actually expecting to see. Yes, I will be adding a moisture filter in the near future, before I attempt to fill my larger 88 cu. ft. bottles.
At this point I opened the valve on the bottle a couple of times, (keeping it in a "valve down" position) for just a couple of seconds to check for water in the bottle.
I did get a very short spray of water/mist out of the bottle, ... but again, not as much as I was expecting to see.
Now was the time to check the oil for any metal residue, and yes I did find some. I did NOT detect any flecks or "glitter-sized" pieces, ... but there was certainly a noticeable amount of "metal powder" suspended in the (now grey colored) oil.
I would best describe the appearance of the oil as having a "Pearlesent" look to it. I flushed the crankcase with another oil change, short motor run, and it looks pretty well cleaned out.
At this point, I checked the full rotation of the motor manually to see if the "binding" had gotten any better or worse. It seems to have been greatly reduced, and I'm fairly confident that if there was a tight spot in the cylinder bore, ... then is is probably better now.
Time (and more usage) will tell.

For those contemplating a purchase of a Yong Heng or clone on ebay,
well ebay is offering a 15% discount on everything on Friday March 30. The promo code is PSPRINGBF. Minimum purchase is $25. Maximum discount is $60. This would bring the price of a Yong Heng or clone from $281 to $239 with free shipping.
-
Glad to hear your compressor is working good Ron. Just a heads up, they say you should open the bleed valve on the compressor just before shutting it off. I have no idea why but I guess it's not good to suddenly shut it down when the head is pressurized? I know that would be tough when filling a bottle that doesn't have a check valve to keep the air from draining back out but figured I'd give you a heads up.
My oil looked the same on my first change. Good luck with it and enjoy the air!!!
-
The idea behind opening the bleed valve was noted to be venting moisture out of the cylinder. I read quite a while back to let it run for a few seconds with the bleed valve open for this purpose. The idea seemingly came from someone who found rusty water inside the cylinder itself. Certainly couldn't hurt to do it and I always start mine with the bleed open.
-
NOTE: I have since discovered that unlike the previous 15% off promo, this one only good on select items so it may not apply to a compressor.

On my Vevor Yong Heng clone, the oil in the oil level gauge turned black almost immediately so I changed the oil after my first bottle fill, then with the drain open I poured more clean oil through the machine. Then I closed the drain plug and filled it up but the oil in the gauge still appeared pretty black. After three more fills I changed the oil again but the oil that drained out appeared pretty clean, yet the oil in the gauge is still black! Anyway since the rest button tripped on my second fill I have done 4 more fills with zero problems. Don't know why the gauge shows black oil.
My oil looked the same on my first change. Good luck with it and enjoy the air!!!

Hey Jim, the way the seal is on the front cover some oil may stay trapped in there when you drain it. See this ad and the picture of the seal. Oil from the main "compartment" flows through the small hole in the seal to the glass oil level window area.

Hi Mike,
I found that after the first three oil changes, done at pretty short intervals, the oil now stays clean, and the compressor runs great and cool.

I hope it will run a wile !!! Im using Royal purple for the oil. All i can do is hope :)

the black stuff has settled, so you basically need to shake up the unit before draining oil
or run it for a few minutes.

I bought a gallon of the Royal Purple synthetic also, but I'm doing fine with the Harbor Freight compressor oil so I will finish that first before I go to the Royal Purple. I figure the best thing you can do for these hard working compressors help them run as cool as possible, and use the best possible lubricant.

Man, it's been a long weekend battling my Vevor/Yong Heng head compressor. I'm ready to throw myself into oncoming traffic, or huck the compressor into the Grand Canyon... I haven't decided yet.
The 15A thermal fuse (resettable) on my Vevor was faulty, kept tripping after running for 3 minutes. After checking all the wiring on the motor, I decided it was the chineseum fuse/breaker, so I had to overnight a higher quality NTE fuse from Amazon. I also had to replace the water pump because the included pump liked to sporadically stop working. After all the replacement parts came in today, I got about 20 minutes of runtime in before one of the quick disconnect fittings on the hose decided to give up. A internal oring on the QD fitting blew out. The QD and hose are used to connect the "gold filter" with drying media cartridge to the compressor's output. I ran the compressor without the gold filter for 2-3 minutes just to see what would happen, and found a bunch of moisture...so running without a filter of some kind isn't really ideal.
I've been under pressure to get my tank filled up because I'm leaving in 2 days to head to some property in the country where I'll have a chance to shoot my new FX Wildcat for the first time that's been sitting in it's box for 2 months. Grrrr
Tweeter, how's your compressor been working ever since you got the check valve sorted? I'm getting really close to buying the Daystate compressor and just be done with it, but $2000 is painful no matter how you cut it.
-
Andy,
I'm sorry for your troubles. Perhaps luck is a big part of the equation, but my Vevor has performed flawlessly for the almost 3 months I have been using it. As I have stated previously I change the oil VERY often, and once I resolved all the minor leaks the compressor temp never exceeds 40 degrees Celsius during a fill. It's now selling for $218 with free shipping on ebay.

I couldn't agree more. Not being a mechanic, that FB group provided all the help I needed to get my pump up and running smoothly and reliably. Great support and as anyone who owns one of these pumps knows, the so called "manual" is totally worthless.

A internal oring on the QD fitting blew out. The QD and hose are used to connect the "gold filter" with drying media cartridge to the compressor's output. I ran the compressor without the gold filter for 2-3 minutes just to see what would happen, and found a bunch of moisture...so running without a filter of some kind isn't really ideal.
I've been under pressure to get my tank filled up because I'm leaving in 2 days to head to some property in the country where I'll have a chance to shoot my new FX Wildcat for the first time that's been sitting in it's box for 2 months. Grrrr
Tweeter, how's your compressor been working ever since you got the check valve sorted? I'm getting really close to buying the Daystate compressor and just be done with it, but $2000 is painful no matter how you cut it.
I can't really say to be honest with you. I have only filled my gun twice since I replaced the check valve and it worked fine. Had planned on doing a lot of shooting this weekend but a bad cold put a stop to that! These compressors are great but be prepared to tinker with it once in a while to keep it working correctly. Kind of like owning a Hatsan ;)

Wished I would have read this post be for i bought mine
But it does seem to be run ok. But heats up real fast. So after reading this post I'm going to tear it all apart and make sure everything is clean. By the way I read the top piston ring is carbon fiber

I made sure that I had Delrin washers in every connection that required them (one was missing) and that everything is really tight. I also put PTFE tape on all the threads. That eliminated all the tiny leaks and my compressor rarely goes above 40 degrees Celsius since I did that.

Thinks jimhenry I will try that witch connections required the delrin washers

Wow I see on ebay there's vervor's priced at $208 also with the make offer option.

In and out of the oil/water filter and the Foster connector to the end of the whip and I THINK also on each bleed valve. On mine the input to the oil/water filter was missing the washer but there were a couple spares included.

Yes so now I could burn through 6 Vevors for less than the price of the $1299 A-V compressor but so far my first one is running fine. Let me add, I also just might be lucky with mine.

You're correct, each bleed valve should have a seal, and every M10 fitting as well.

Hi thanks guys it was missing one washer. No leaks filled my 68 cube inche tank for 0 to 3000 psi. In about 2 minutes but still hit 60ｰc not sure what to do to keep the temp. Down. will just have to try something different.
Thanks again for the info.

Neil,
You can always add ice to your cooling water and make sure you have a good 5 gallons of water. Also, use the Teflon tape on threads. Make sure all connections except the bleed valves are WRENCH TIGHT, and the bleed valves should be as tight as possible that you can still release them before shutting off the compressor. Going forward if you hit 60 degrees, or better yet 55 degrees, shut it down for a bit and let it cool.
What oil are you using?
-

I watched a youtube video of a guy filling a very large tank (oxy-acetaline size) with a yong heng to about 200 bar - took him about 40 minutes continuously
His trick was to use tap water in through the yong heng, and out of the yong heng straight down the drain
If you don't re-circulate the water, end of problem
I've salvaged the copper pipe cooling radiator off the back of an old fashioned refrigerator - perfect as quarter inch tubing and has a heat radiator attached - thinking I'll use it in the return feed from the pump when I switch from direct filling to an air tank, as my water supply is metered and I pay for every drop I use
-
Hi ok I have put teflon tape on i did forget to put some on the go and low pressure tubing but they don't seem to be leaking
Oil is Ingersoll rand select synthetic. The water seems cool to the touch and the top piston doesn't get to hot but the first stage air line is way hotter.

Neil,
Is your oil non-detergent ISO 46? If yes then I am mostly out of ideas. I know that some people use anti-freeze coolant and ice in their water, but I don't. I don't measure the temperature of the water separately but it does not get noticeably warmer to the touch. If you are using the right oil then I suppose you might need to rebuild the pump, or at least stop it frequently and let it cool down.
Jim
-
Ok this might be part of the problem and hopefully well help some of you guys took a close look it the low pressure tubing
And it has a flat spot in it instead of a nice round bend. Thinking this is a choke point causing the raised temperature
Jim yup non detergent compressor oil.
-
subscribed...my Vevor was working fine but now it will not make pressure past 300-400 psi. I've swapped out the check valve on the high side and not luck still...I might need to tear it down and look further into it.

I'm thinking f getting one of these compressors on E Bay, within a few weeks
They all seem to be coming from California so I'm guessing it is one vendor
Any ideas or suggestion before I do order one will be greatly appreciated

Well if you get one make sure you check to make sure all the fittings are tight and there is no oil or any bits in the lines or cylinders

Use the right oil, non detergent ISO 46 compressor oil. I use Harbor Freight compressor oil but when I finish that I have a gallon of Royal Purple synthetic compressor oil that I will switch to. Do your first oil change after 15 minutes run time to flush out any debris. I found that after the first three very frequent oil changes, the oil now stays pretty clean. I have just purchased a run time meter to wire in to the pump to better measure my maintenance intervals. Always, always, always start the compressor before you close the low and high pressure bleed valves, and always open them before you turn the compressor off. My Vevor came with a rubber mat to sit the compressor on but if yours does not, find something to run it on to dampen vibration. If your compressor reaches 50 degrees Celsius, shut it down and let it cool. I know the manual says 65 degrees but I prefer to err on the side of caution. As someone else said, make sure all your connections are wrench tight, and also make sure that all fittings that require them have the Delrin washers in them. As an extra measure I also wrap all threads in Teflon or PFTE tape. This is all because the more you can eliminate even the tiniest of leaks, the less hard your compressor will have to work, extending its lifespan. If you need to fill something to 4500 PSI, stop at 4200 and call it good enough, that will save a lot of wear on your compressor. If you need to fill from 0 to 4200 PSI, stop several times to let the pump cool down. Finally, BE LUCKY, as there are good ones and bad ones.

Norm,
They probably all are from the same vendor. I bought this one but paid $281 with free shipping. Then I had a minor problem and they gave me a 15% credit. I am very happy with both the pump and the vendor. Since they have a Make Offer button, I bet they would take $200.

For all with Yong Heng knockoffs, here's a link to Chad Simon's store that has access to some of the hard to locate parts( i just ordered some of the delron 2nd stage seals.

They talk about all these tiny compressors(Tuxing, Yong Heng, Yong Heng Clones)
Just another good source

Yes, they are-most of the other knockoffs have rings along with the Tuxing-might send one to my friend in Florida and have him make it out of a tougher duro rating- these are pretty soft delron to stand up to the heat & pressure produced. Trying ti find out if he has the1st stage rings, also

Well ran my new Yong Heng compressor tonight and I was a little surprised!
1st I ran it for 30 minutes and the temp went up to 60C
2nd in the 30 minute time it filled my 30 minute tank from 0 to 3000 PSI
3rd the amount of moisture in the air was unbelievable! The little cotton filter in the end of the fill whip was saturated. I turned my tank upside down and opened the valve till no more moister was blowing out. I left the tank upside down and will blow it out again in the morning.
4th I was also a little surprised how hot the tank was when I shut things down.
The oil viewing glass showed the oil was pretty dirty so I did an oil change refilling it with Synthetic ISO 100 oil.
I should be good to go in the morning and will keep track to see how long it takes to go from 3000 or whatever it is after blowing it out and letting it cool till it reaches 4500 PSI. If it is not at 3000 PSI I may top it off and let things cool down. After that I will top it off to 4500 PSI so I will have a pretty good idea how long it should take in the future as I refill my tank back to 4500 PSI when it does get down to 3000 PSI when fill my PCPs
I will try to get some pictures when I have the extra time
-
The recirc water on my YH reaches into the low 50's (C) while pumping, but it has not been an issue at all. I understand the desire to run these as cool as possible (and agree with it), but 50-55C, even 60C, isn't going to hurt the system or accelerate any wear and tear, assuming you're running a decent oil in it. Here's a graph where the water temp and the temp of the 1st stage and 2nd stage pipes are being measured by a thermocouple on each pipe as a 6.8L CF tank is topped off from 3500psi to 4500psi. Total run time is about 13 minutes. The water temp reached about 50C (sorry, I converted everything to *F in the graph). Like others, I've never had any troubles with mine and I've filled that 6.8L CF tank from 3200psi to 4500psi at least 10 times now. I change the oil after every 3rd fill and it now always comes out clean. Using Mag One bc that's what I have (but RP is far superior imo).

As you got your yong heng at a bargain price, I suspect it is the cheapo version - the compressors are basically 2 types - simple with 2 pipes, and hardcover with 3 pipes - and the 2 pipe version does not have the oil/water separator with bleed screw on the left hand side looking from the front where the oil view window is
What did you get - 2 or 3 pipe version?
-
Well mine is EXACTLY like yours with the 3 pipes and bleed screw on the left.
I was fortunate to get it at "cheapo Price" because of the 20% discount offered by E Bay for a 12 hour special that day and a reasonable counter offer from the seller to my offer. It was not listed at BARGAIN PRICE but right inline with the other yong heng compressors at the time I made the purchase.
BTW maybe you should use "lower price version" in place of your "cheapo version" next time you comment on something a member has just purchased! If mine is the cheapo version so is yours!!
-

I never said the 3 pipe version was a cheapo version - the 2 pipe version is the cheapo version (no oil/water separator and lower output volume) - I was thinking you likely got the basic model 2 pipe version, not the hardback model, as you paid a low price
I quickly learned to have the rifle higher than the compressor when direct filling - so water runs back down the filling hose
I will eventually get a tank and have that higher than the compressor when filling
-
This is what you said "As you got your yong heng at a bargain price, I suspect it is the cheapo version" is what I was referring to and like what I said "BTW maybe you should use "lower price version" in place of your "cheapo version" next time you comment on something a member has just purchased!"
I was not referring to a 2 pipe or 3 pipe Model just the statement you made.
Also I personally would never say what you may have purchased was a Cheapo Version but would have said a lower price model as it may have been all at person can afford and are very happy with it.
Anyway enough on that subject!
I'm very happy with my little compressor. It filled my 30 minute tank from 3300 PSI to 4500 PSI in 15 minutes this morning and only reached 54C and the little filter in the end of the fill hose was barely damp. I will try to make a stand to elevate the tank higher to help prevent ANY moisture reaching it. One of the Gold colored filters is on my buy list.

Norm,
Here is my little cheapo compressor working like a champ! You can get this black filter for $57 shipped from lethalprecision and ships with a bag full of spare filters. The one thing we need to find out is where to get spare second stage rings for this compressor, mine came with two spares and I've already had to swap one out. Easy 10 min fix.

That's a design I've not seen before - 2 pipes like yong heng basic low output version - but you've got the oil/water separator like the hardback 3 pipe yong heng
My guess is that it's a low capacity design, which is not really a problem as you can fill in stages
Alternatively, it could be similar to tuxing design with internal transfer of first to second stage compression, rather than using an external pipe - which could make it a high output version

I like it better than yong heng design - the yong heng has a vulnerable pipe coming out of the top of the cylinder - I constantly bang that pipe with objects

I have both the yong heng and the vevor, they both fill at about the same rate. Just got the yh and filled a 30min scba from 3300 to 4500 in about 10min. Timed the vevor the other day, it filled 30min scba from 3100 to 4500 in about 13min. Vevor temp runs at about 65deg the yh ran at about 60deg. Both with a three gal bucket with 6 frozen water bottles in it for cooling.

It's getting confusing now with all the different designs
Just seen a new design with only 1 pipe and a lower power motor - and no mention of the air flow rate
The cheapest yong heng with 2 visible pipes, listed as basic or streamlined version is 40 liter per minute output, the other 3 yong heng versions with 3 visible pipes are all 50 liter per minute output
I guess whatever brand or model you buy, look for "Air flow rate: 50L/MIN" in the specifications

Why can't somebody tell us where we can just buy our own second stage seals. Is he gonna get rich selling these things. For instance I've sent him 5 emails already (over the course of more than a week, 1 to each of the emails on his website and 2 to his personal) regarding these stupid things and finally got a response that said "I have to order more so it'll be at least two weeks". So now in "at least two weeks" I have to start sending out more emails hoping to get in line for a few of my own diamond encrusted 24 karat limited edition piston seals. Ridiculous.
I don't mean to sound whiny but this is getting old just for a puny little plastic seal. I'm gonna make a movie called "Blood Seal" in which I travel to west Africa to dig up a piston seal and have to swallow it to sneak it back to the U.S. through customs. Get it? Get it? ;) ;) ;)

Tweeter-did you go thru Chad Simon? He's dealing with the same BS we all are for these 1 of a kind seal, but is not the distributor(they come out of China-so 3-4 weeks, if you can chase it down) He also does not deal with these clones, so go easy on him or he's liable to say" I'm Done" I had to work long and hard to track him down as a source, so as soon as he gets them in,I'll let you know-also working on my good friend Mike Kobel(Citrus Air) to come up with some higher strength duro to cut on his lathe that will hold up to the heat.I've had to replace these F**cks 3 times! and with this clone Yong Heng, it's a pain in the balls! with all the piping- My Tuxing has 4 rings(not steel) that are simple to re-do & no major surgery involved- if I hadn't got this clone for free, I would junk it just cause of parts issues. I am saving up for an Omega Super Charger- ~ $1800 & built a lot more solid than the Air Venturi, in my mind-+ scads of xtra features-

This is why I bought a Yong Heng - good reports and spares readily available on aliexpress
Tuxing has some bad reports, but you can get spares easily on aliexpress
Vevor? - seems to me to be just a brander of other peoples manufactured products - who actually made the air pump?
I looked, and could not find any mention of spare parts for anything that Vevor sell, but they have an official store on aliexpress:

My piston rebuild with a YH style high pressure piston was a fail. The high pressure rod was a larger diameter and would not fit in the head. Also the piston rod was shorter. All I needed was the piston and it was the same. I have it back together and it's move a large volume of air under no load. Going to later let it run a little longer with no load and see if she stays together.

So, can't get the seal, can't fit a yong heng piston either
I'm so glad I researched the various makes and models first, then decided I'd only buy a yong heng
I did see a compressor branded DAVV that was really tempting - looked like a better compressor, as it was a V-Twin design, but I was not sure who the real manufacturer was, if it would be reliable, or if parts were available - so I played safe

Yup when this one quits it's yong heng land for me. Problem solved.

Hi,
Am getting burnt smell from the air that is filled into the scuba bottle. Changing the oil and using a different bottle to test if the burn smell remained - it did not work. The burnt smell continues.
I have a large external golden filter that I procured seperately for the compressor attached.
Any idea what could be the reason for this?

That smell is common, as the compressor breaks in the smell will diminish.

My response was, "That doesn't even make sense but thanks for the reply!" Good grief
Still on the hunt for the elusive second stage unicorn seals, I wish I had the equipment and knowledge to make some myself. All we need is for them to be made of high quality material so they last longer.... They are easy enough to swap out in 5 minutes........
-
On a positive note, the other Vevor ebay seller I asked for these seals said that he would check with his supplier to see if he can get some to sell and he would respond within 2 days. Maybe, maybe...
FYI, I have about a million burst discs and white "donut" seals if anybody needs a few let me know ;)
-
I contacted one of the sellers on ebay who sells the Vevor compressors to ask if I could buy a couple bags of spare o rings and seals that come with the compressors. This was their response lol.

That is funny! ;D...yeah when I contacted them about mine I got those types of responses from them...then after about 10 of them, they finally gave me a partial refund! LOL...So I guess if I can find the 24kt unicorn seals, I'll be good...someday! lol...
I agree, these little compressors work fine, just that darn second stage seal wears out QUICK!!!
-
if you guys have a facebook acct try aven chang,, he will give you the right parts,,as long as your compressor is a zhong yang ,, yong heng is made by zhong yang,
-
Ours is a vevor and uses a different type piston ring/seal than the YH, thanks for the info though! It may help someone.

Just look at them sitting there.... So beautiful and elegant! So close yet so far away......

Tried that and he sent me packing. Seriously, he wanted to sell me a whole piston assembly, not just the seal. Then when I told them they wear out quick and just needed some spare seals, he told me again they only sell the complete piston assembly. Then I told them I would spread the word about the crappy CS, he said, go ahead LOL

i dont know best thing to do i guess is to go to the zhong yang site,, they have different compressors ang yong heng is one them.. i have a yong heng basi model,, most of the compressors here on my side have the yellow one branded as airking

This is the exact same pump I have, except the base is blue, not red. Other than the color, its identical.

Marko (MJP) knows the type of material we need to have these made out of. I forget the name but I'll try to find his posts where he tells it.

I think they would find that they sell a HECK of a lot more compressors if they would offer spares for the wear items. At least sell a kit!
Jimmy, that's horrible customer service. Ought to post that in the buyers/sellers/traders feedback section and send them a link after the entire forum has a chance to flame them hahaha.
-
This is the stuff we need the seals made from! Copied from Marko's post:
Tweeter, any machinist can make you the spare second stage seals. Just buy some graphite impregnated ptfe rod for the material.
Very easy part to make on a manual lathe, and super fast to make a lot on a cnc.

It's blow by from the piston. I recently opened up my gold filter which has the tampon material > drying media cartridge > tampon and both tampon filters reek of burnt oil. There's not much I can do about it, and these Chinese compressors aren't high enough quality to produce breathing air (which would not contain traces of oil), so I'm just living with it. I've debated buying a moisture separator which would go on the compressor output before the gold filter, but I'm trying to refrain from dumping any more money into these Chinese units and will probably end up with a Daystate compressor before year end.

Ok finally!!! Aven appears to want to help me out!...anyone interested in a group buy since shipping is the same? Or I plan on buying the 10 sets and keeping 5 for myself and will sell the other 5 at cost. Let me know, I'm getting back to him today.

Great find Jimmy, nice to know that they are obtainable after all lol
-
sounds good, lets see if anybody else will be interested, I plan on getting back to him this afternoon cause of the time differences.
-
We'd better buy them quick before some piston seal pirate buys em all and upcharges us ;D ;D
-
absolutely, thank you sir.
-
Justin, yeah, I plan on buying them this afternoon, just want to see if anyone else needs them, I might just buy a few spares to help a few members out if they dont get a chance to see this post by this afternoon. Finally, found the 24k diamond encrusted unicorn seals!
-
I wasn't rushing you bro, I actually had that written before you posted it just took me awhile to find a good pirate picture on google images haha. I'd be happy to share my bounty with other members as well. At least they really do exist!

I'd like to get maybe 10 sets of these as well. Anyone ordering a lot of these please contact me and I'll send funds to you.

The way my hands shake these days I'd slice my thumbs off before slicing anything else. Maybe that's why the groups are getting bigger. Hope your efforts help all with the seal issues.

I'm only doing this once, but figured if anyone want to jump in, now is the time! I know JSAR is making some new ones with better materials, so hopefully those will also be available soon.

So what do they mean by only selling you the whole piston? Does that include the piston ring? I have seen just one case of a broken piston on this forum but it still might be worth having.
from the looks of the piston it seems its not his product, might be the reason he offered you the whole piston cause it the seals might not fit
No, its his product!

Travis, I'm sure I'll be ordering some of the new upgraded seals you are making, these wear out quickly on my compressor. In the meantime I'm placing an order for some of the stock ones from China. :D...need air, my guns don't shoot without it! ;D

Thanks for the offer dude but Im just going to wait Senor Travis to come through for us. If that doesn't work out, then maybe I'll pile in on the next order!
Thanks again.

+1 I'll def. still go for Travis' new piston when it is available but for a few bucks now I'll grab a few of these to have on hand. Thanks Jimmy and thanks Travis for developing another alternative for us!

I have actually filled in more than 15 tanks with it and the smell continues.
Hence my question.
I used the synthetic motor oil at first and then switched to the Hydraulic oil of the suggested grade.
Does the burnt smell means that the pistons are letting in oil enter the compressed air chamber?
Hi,
Am getting burnt smell from the air that is filled into the scuba bottle. Changing the oil and using a different bottle to test if the burn smell remained - it did not work. The burnt smell continues.
I have a large external golden filter that I procured seperately for the compressor attached.
Any idea what could be the reason for this?
That smell is common, as the compressor breaks in the smell will diminish.

I may have missed this, and if I did I apologize for it, but can someone post a link for the better filter options for these pumps.
Thanks.

I just received my (not) Yong Heng compressor of e bay. The case is black, not blue. The compressor and innards all look the same as yours. Only one single cross tube. The cylinder looking object is probably the start/run capacitor for the motor. Mine was banging around in the case so I mounted it on the outside. I got the 110 volt model but it had the stop run pressure gauge. ( it didn't work) No instructions to speak of. Water tube was also worthless. QUESTION Should water enter the top or bottom of cylinder, or does it really matter. Have gotten good water tube, added oil and run for a few minutes. Finally, topped off three rifles using pressure release knob to control output. Little compressor worked great. Ask me again in six months.

Theory is that it is easier for water bubbles to be pushed out/escape, if water enters from the bottom and exits on top.

If you look at the pic in tweeter's first post, my comp. is identical to that one, only black case instead of blue.As some have said, I was only going to use the gauge stop as an emergency stop. I too prefer to dump the press and stop the charging process. So far it is working great. Lots of spare parts and seals. If this thing works for any time at all, it was a super bargain. 225.00 Seller on e bay refunded 55.00 after I complained about bait & switch, ungrounded power cord, banging noise in case, wrong color and useless water lines. Total cost 170.00 Thanks xracer for the water direction question. Makes sense.
-
I would add also, my kit came with lots of extras. At least two extra second stage seals, lots of o rings, blowout disks and other things I don't know about. Important to keep second stage cool as possible, whether seals or o rings on piston. Also watch the wiring. Mine seems to be as small as possible and still work. When I lifted the case to see what was banging inside the tiny wire to the switch broke off. All fixed now, but next time it will get a little heaver wiring.

IMO and from all I have read, it really doesn't matter in this application. Just make sure you have good water flow through the pump

I noticed the really bad crimp connections on my compressor as well. I ended up tightening down the crimp with some needle nose pliers and then soldered the tabs to keep it locked in place. I was also pretty suspicious about the small wire gauge, but it looked like it's a pain to pull the motor out to get access to all the wires to redo it. I'm leaving mine as is for now until some other component lets out the smoke.

WHY would you use hydraulic oil?
IMO a good oil for this would be Jetlube 1 iirc
Used in helicopter gearboxes rec'd by Jim Sheldon of Walter Kidde compressor supplier.
I use it in my W/K
BTW anyone have a pic of 2nd stage suction valve?
TIA
-
Watched some excellent youtube on these compressors by Sambo Cotton.
Inside the water jacket he observed corrosion. I think to avoid that use antifreeze compatible with aluminum for coolant. Bonus if in an unheated shop it won't freeze.
-
I have been calling my compressor a yong heng but it appears to be some sort of clone maybe? Looks alot like the yong heng with a few major differences. Obviously no Yong Heng written on the side, the small hose filter is a bit different, the burst disk sits directly on top of the second stage, water hose connectors are different and the major difference is on the inside. Mine doesn't have o rings on the second stage, it is some sort of plastic bushing which I'm sure will be a nightmare to find a replacement for when this one wears out. May have to just see if someone can make me some?
I can't complain really because the ad that I bought it from called it a Vevor compressor but the picture they showed WAS a yong heng. Another member here bought a Vevor compressor from the same seller and said he actually received a yong heng. Thats what I was really hoping for but no big deal as long as it works. He did say that his came with a small amount of oil in it as well so I'm thinking that they test them before shipping and can't drain ALL of the oil out. Mine just happened to spend most of its time upside down which gunked up the top end.
Has anybody else seen a compressor like this one? I am a bit concerned as all the reviews showing the yong heng as a safe little compressor mean nothing now. Who knows if this thing will hold up under the kind of use the yong hengs do? I will be filling to 3500psi for awhile to play it safe.
I'll be happy if it lasts me the summer and then I'll either get a REAL YH or maybe the AV Nomad from pyramyd air (if reviews look good).

Hi,
Did you manage to source the plastoc bushing?
Have busted mine. Have the similar model.
-
OK I read entire post. I just received my Vevor compressor. This thread left some questions unanswered. 1, Did the seals ordered work? 2, Are they still available? 3, Did Travis come thru with improved seals? 4, What is recommended oil? I've got a gallon of AW46 orielly brand. Royal Purple? If there is a current thread that addresses this let me know. Thanks
-
My Vevor worked good but oil is very dirty with less than ten minutes run time, most of which is with open valves. When I did pump up the neutron star to 4500psi smoke was coming out case vent. Temp never rose and water was cold coming out. When I pulled quick connect off probe there was cotton like material in both. It blew thru the screen in probe. So now I have to try and clean out the pressure line and quick connect.

If the oil is dirty in 10 minutes and smoke is coming out of it then you have the wrong type of oil. I started mine with Mobil Jet II but have some Seco 500 on order.
I have no idea if my supposed YH is actually a YH or not.
-
Another reason for smoke is being too full.
That said... there are several models hacked copied rebranded sold by VEVOR. How about some pictures so we know which models we are talking about here.
-
I leveled the pump and filled to center of dot. Using AW46 from O'Reilly. No smoke came out until it got to 3000psi. I ran it close to ten minutes with no load. Mine has the blocks with drain plugs on each side. It's really not very loud either (but I have hearing loss).
