Yong Heng (4500-psi) - Compressor Quick Review And Instructions 

Nice demonstration and review. I too have 3 of these units and the oldest is 3 years old and running. I too have a similar configuration but recommend that your large filter be verticle with the outlet at the top so gravity keeps solids and liquids on the bottom rather than pushing it along through your media, also be sure to open that vessel and allow it to air dry to minimize any corrosion. One last bit of friendly advice is that the little submersible pump that is provided has a very limited head rating of something like 24", consider upgrading to a pump with a greater head capability with flow rate adjustment. Again awesome video and thanks for sharing!

Had my Yong Heng for 3 years and had zero issues,I attached a extra large filter,gold colour cylinder plus fitted a moisture filter to air intake. Fills FX Streamline .22 from 1200psi to max in about 5 minutes. Also fill a Air venturi Avenger to 4000psi in about 7 minutes Instead of using ice,I've used the blue freezer packs you use in coolers,just helps keep things cooler in summer,also use mine in basement where I use dehumidifiers which helps keep moisture below 60%

love my yong heng for the $287 i paid it has been great for me. good review 👍

I absolutely LOVE my 'Heng. It's really sweet. I can fill 4 PCP's from empty to full in a few minutes and it never gets above 100˙ƒ. I use refrigerated distilled water and I leave the fish tank pump in the gallon (cut a slit in the side) and have the two tubes coming out the top. Takes me 30 seconds to set up.

I got one coming so this was good to see how to run the Yong Heng and to fill a gun like I'm going to do too. Thanks

Push your temp guage probe in all the way for an accurate reading. Also you should keep your coolant bucket higher than the pump, it will make your water pump last longer and work more effectively. I also add some ice to my bucket.they also suggest 2 gallons minimum of water, i use a 5 gallon bucket with a few cups of antifreeze and some "heet" good video man.

MAY-BE TRY COOLENT BUCKET ABOVE THE MOTOR GRAVITY PUTS LESS STRESS ON THE WATER PUMP.

Will it not power on until the item you're filling is connected?

How do you determine what pressure to have the compressor at? Should it be right at the max psi for your rifle or above that?

Appreciate the video. Could you supply links for the filter, pump, and any other add-ons as that would be helpful as it looks like you have it pretty well figured out. Be curious of the model number/type of compressor that is. I need to do something to get away from hand pumping :)

Hello, I have a question, I was using my Yong Heng today for the first time, I am filling a big 9L 4500psi carbon fiber air tank. I changed the oil in the compressor when it got to 1000psi for the break in, and then when it got to 3400psi, I noticed the oil was dark, so I changed it again, and I decided to check the ice bottles I have in the 5 gallon water bucket, Now when I reached into the water all the water had an oily feeling to it. Is that normal for the water to feel oily? I did not finish airing up the air tank after the second oil change at 3400psi. I am being cautious I do not want to damage the compressor.

Anyone got any input on that, I think it's made by GX pump or something, but it's a one piece air-cooled unit. No bucket of water, no oil changes Guys seem to like it a lot, I'm just wondering about longevity. It's $480 or so.

I used to think the worst purchase I ever made was buying a boat until the day my young hang air compressor was delivered, AAAAARRRRGGGG!

And another downside is: Well there are many. This thing if actually used weekly will not last six months. It is actually a cheap piece of junk, regular use it will not withstand. Use it once a month, OK it may last a year. So 350 bucks for the compressor. 60 bucks for hydraulic oil 200 bucks for a decent filter to get rid of water 400 and up for a decent 4500 psi tank. So that is 1010 bucks........conservatively-plus other odds and ends. Uh oh......not so cheap in price after all!! Or just go buy and Omega Trail for 900 bucks and fill your gun direct and forget all the aggravation, down time, and worry about water in your air gun or tank, and toss the tank also, you can carry the Omega with you, hook it to your car battery, etc, etc, or fill up your gun direct at home from the nearest 110 outlet. Yong Heng used to be a less than ideal solution , as time has progressed it is now only an exercise in frustration that will actually cost more than a modern decent high pressure air compressor. Times have changed, progress has been made. Check out the small direct fill compressors designed to fill your air gun directly. This is currently the best and most economical way in our current world.......or cheaper yet, go rent a 6000 psi Nitrogen tank and buy a regulator and enjoy 100 plus fills per tank and a yearly rental of on average 125 bucks and a fill 75 bucks , regulator one time cost 200 bucks. 200 bucks a year, by 100 fills equals 2 bucks a fill. Let them worry about the tank safety and hydrostat. Cheers Kit

Theres no point in having a moisture filter laying on its side as moisture lays in the bottom of the filter laying down and therefore bypasses the the micro beads!! Filter should be verticle to be able to do their intended job.

If you enjoy shooting and like your guns , run away from this Yong Heng compressor. Save and spend the extra money so you can get a good quality, well made compressor mine cost me about $1600 and that money resolve all the headache and troubles that I was having with the " 2 " Yong Heng compressors that I had previously purchased. Take it from me don't waste your time fixing , adjusting and filtering oil and water its just not worth any hard working man's time .
