    This is my new compressor and tank setup. 

    The Yong Heng Compressor

    It’s hefty and looks well built. The user manual is not the greatest, but I figured everything out before I used it. I’d probably not recommend this for someone who’s not mechanically inclined. I’ve seen some how to use videos by guys not using it right. 

    I shopped around and found a seller on eBay in the US who has the 110VAC adjustable pressure auto shut off model for the price of the base model. It arrived in 4 days in perfect condition. Grainger was the only local place I could find the correct oil. I bought a gallon of Mobil 427 ISO 100 anti-wear compressor oil. The user manual says ISO 46, but then recommends Mobil 827 ISO 100. Go figure. I went with the 100. After putting a total of 1 hour of use on the compressor, the oil had a clear medium gray appearance and I decided to change the oil at that point. Likely the gray is metal sediment from wearing in of the compressor parts. The compressor runs beautifully and fills fast. $268 for the 110 VAC adjustable pressure compressor and $41 for the gallon of oil. 

    Water and Oil Separator 

    The small separator that comes with the compressor will be very saturated with water and some oil on a 30 minute run. You absolutely need an extra filter. I added a hefty 18” Tuxking separator after it. The small one removes most of the condensation and the large one takes care of the rest. I modified it though. I inserted a 6cm piece of the fiber filter at the inlet end filled the rest packed tight with blue indicating molecular sieve beads and then a 2cm fiber filter piece at the outlet end. 

    After a 30 minute run with no periodic opening of the drain valves, the compressor’s small separator is saturated. Then inspecting the outlet end of the big separator, it is completely dry and no oil residue. At the inlet end there is some moisture and evidence of a little oil residue in the fiber filter, but most of that piece is dry. I ordered a small 5” fiber separator to add before the big one. The idea being to contain all the liquid condensate in that, which will mean that the molecular beads will be depleted less. One other mod I’m making is to put a check valve on the tank connect line so I can bleed the compressor to no load before shutting off. Just something that’ll take a tad more stress off the compressor.

    Releasing some air from the filled tank, I don’t smell anything other than some new tank smell. Nothing oily or otherwise. I feel very confident that this big modified separator is doing an excellent job at keeping the tank dry and oil free. $89 for the separator and $30 for 2 lbs of molecular sieve beads.

    The Tank

    After browsing lots of SCBA and SCUBA tanks, I decided to buy an iorman 3L 4500 PSI carbon fiber SCUBA tank with the valve and hose included. It’s an excellent well built looking tank and valve setup! It looks very  made. I bought a very nice padded shoulder bag made for the tank. $299 for the tank setup. 

    Summing Up

    I’m very happy with this setup for $729 including the oil and sieve beads. When the 3L tank got down below 3000 PSI, it took 7 minutes to charge it up to 4300 PSI. When charging my PCP rifle, the tank valve gives you good fill rate control. That 3L tank will give me plenty of refills for a day out shooting. I estimate it’ll fill my Gauntlet 25 around 14 times, which takes about 2 seconds. 

    I was looking at the Nomad compressor at about the same price as this setup and I’d much rather have this setup! The on the go mobility is far better. I can fill this tank from low in 7 minutes and take it with me anywhere and get around 14 or so quick refills instead of having to go connect up a noisy compressor, be tethered to a power source,  and then wait for the rifle to fill.

    Very nice setup enjoy it. I would recommend that you mount the gold filter vertically instead of horizontally that will get you the most use out of the media.

    I don't know if it's a typo or you are a little confused about the capacity of your three litre tank. A 60 minute SCBA cylinder has a 9 litre capacity, giving it 3 times the space of your bottle. If you lift the coolant container level with the compressor, the little water pump won't have to work as hard. I think that they are only rated to lift about 3 feet.

    If you want to get more cooling water to the compressor just get a bigger pump

    https://www.amazon.com/dp/B017R708QO/ref=psdc_2975475011_t3_B07NRJFLSD

    this pump is under $20 and can do up to 550 gpm fish tank submersible pumps are cheap and reliable. I have some in my fish tank at home that have been running for 8 years only stopping for semi annual cleaning.

    i use a ryobi  wet tile saw pump from home depot works great and add ice to the water .

    I have had my Yong Heng a bit over 2 years, have not had any issues. Watch the heat, watch the oil level, pop the drain knob while running every 5 minutes or so. Take care of it and it will take care of you. Good luck…

    I have been. :) I wasn’t sure how it would all workout, but it was fine on the first run. As far as the filter, it only gets a few drops of liquid and the beads are packed tight, so I haven’t seen a need to put it vertical. I plan on putting another separator tube of fiber ahead of it to catch all the liquid to make the beads last longer. I have about 2 hours of run time and the indicator beads are still very blue. That 2 lb jar of beads will last a long time.

    Nice! I ordered one. The cooling is kind of marginal with this pump.

    Know idea what I was thinking. lol I don’t deal with a lot of mixed volumes and capacities and got one tank mixed up with another smaller ci tank. The pump is definitely marginal and I have another much higher volume one coming.

    So far so great! I ordered that pump as well. :)

    With the stock pump on a 21 minute run it took 7 gallons of water to keep below max temperature.

    I’m the type that has decades old gear that works like new. I’m particular about how I operate things :) I prefer running it for 20 minutes max, which works out just perfect with the 3L tank. I haven’t seen a need to drain while running since the big molecular bead filled separator is still dry after a 20 minute run, except for a light dampness in the small fiber piece at the inlet end. 2 hours of use and the indicator beads are still deep blue.

    I believe that the supplied pump is quite adequate. I have a slightly larger capacity unit that I bought for a spare. So far it has not been required. The only real advantage of using a stronger pump is for its' higher lifting ability. The size of the inlet and outlet spigots limit the flow through the water jacket. IMO using ice is not necessary, like you have found, a large tub of water is enough to keep the temperature stable. I agree also, that the filter should be mounted vertically so that any moisture that condenses in the hose doesn't end up in the filter. I have also found like you, that the little supplied filter catches 90% of the contaminates. I consider the large gold filter as overkill and a waste of air. I'm now using the smaller black type one that is available from eBay or AliExpress. Fitting a check valve at the tank end has a number of advantages and is probably the best tip for improving the safety and usability of these things.

    I think a higher pump flow may negate needing extra water for my at most 20 minute runs. As far as the filter I’m swapping out the little black filter for one that maybe the black one you described. It’s definitely overkill, but, the filter media will last a very long time and the air couldn’t get any drier or oil free. lol And yeah, that gold filter charges up with enough air to power a PCP decently. It’s kind of annoying with these filters that they mix 1/8 NPT and M10x1.0 fittings.

    What I was trying to say was, that a higher flow rate pump won't flow more water because the inlet and outlet size restrict the flow in and out meaning you will get higher pressure upstream from the inlet making the pump work harder but the return flow will be only marginally higher. The supplied pump has about the right flow rate for the diameter of the hoses and spigots. In my experience, after initial run in period of an hour or so, the temp. Stabilizes at 50-55C depending on the ambient temperature, with only 4-5 gallons of water. It did get as high as 65C whilst breaking in. You are learning about the different thread standards, BSPP is another you'll come across. You will also run into compatibility issues with the different Foster connectors. I now have a fairly large selection of them and can rig up just about every type of combination that I need with as few joints as possible for less chance of leaks or blown seals.

    my problem was the  stock pump was intermittent and would stop working all in a sudden.
