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

Do you use the beads in the gold filter?

redtrucker610 · « **Reply #5 on:** March 10, 2018, 08:11:25 PM »

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?

bandg · « **Reply #11 on:** March 11, 2018, 04:34:06 PM »

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

Tweeter · « **Reply #13 on:** March 11, 2018, 07:03:54 PM »

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)

Tweeter · « **Reply #14 on:** March 11, 2018, 07:09:19 PM »

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

Sprungout · « **Reply #15 on:** March 12, 2018, 08:41:42 AM »

Maybe wrap a dryer sheet around the breather? I’m 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

bandg · « **Reply #17 on:** March 12, 2018, 11:18:52 AM »

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
