TUXING 4500Psi Air Compressor filter,Pcp Water Oil Separator Molecular Sieve Diving Separator with 8mm Female and Male Quick Connector for Pcp Air Rifle Scuba Tank Charging L350*OD49*ID36mm Gold

It works great.

Perfect for my needs and under 100 bucks I'd say its a bullseye win for me

The male quick connect would not work with my female end from my compressor. Have not been able to use it yet, but appears well made.

First unit I rec'd had two problems, one I fixed myself, one I could not. First issue is the quick disconnect or Foster fitting was too big by about 3/1000 and none of the female connectors on the compressor feeding it would fit over the male input on the filter. I had to use fine grit sandpaper to lessen the diameter enough so the male input on the filter would fit inside the compressor female output. 2nd issue, I could not fix, it was a leak at the crimp on the output side of the air filter hose. I ordered a replacement and it came next day. All I needed was the new hose, so that's all I used from the replacement package. Put the new hose on the original unit I got with the reduced diameter fitting and all seems right now. Be CAREFUL when tightening the end caps, the O-RING is very loose, if you aren't slow and careful, you will pinch it as you close up the unit and that will close a leak.

PCP tanks, need dry air. Period. Buy this filter for PCP. You don’t need the activated charcoal since you are not breathing from the tank. All you need is the desiccant pellets, and this filter is packed with them, plus comes with spare. Built like a tank also.

Does what it is supposed to do... now paired with a pre-filter with check and purge so I can break up the fill cycle and not lose the air in the filter.

O rings are too large in diameter and not sufficiently thick to fill the space they are intended to seal. Even with very careful closing of the unit, the loose O-rings get pinched, which causes leaks. After a few openings and closings, they leak anyway, even if they don’t get pinched. The extra O-rings are nice; however, if the O-rings were the correct size, spare O-rings would be superfluous. The unit has no internal condensate trap or drain so (in a humid place) only ten minutes of pumping fills the cavity between the media tube and the shell with condensate. The entire product must be completely disassembled and dried with rags. If you don’t, the condensate will be absorbed by the media, saturating the media. I filled a scuba tank half full and the media was so saturated that water got into the scuba tank. This was done indoors, with the windows shut. Update: I received a communication from TUXING. They were very courteous and apologetic. Hopefully, they are listening and add some sort of drain mechanism. I subsequently purchased a supplemental mechanical water separator for $138.00. TUXING advertised that their $70 product could do the job alone. That's why I bought it. Updated Update: Turns out the courteous communication I received was a form letter. Subsequent communications revealed that no one there can read or write English well enough to service their products.

Works as it should after filling 3 45min bottles from 2000-2300psi. I put an additional passive water trap after the desiccant and it was bone dry after topping off three tanks. Time will tell how long it lasts, I was pleasantly surprised that it also includes a “rebuild” kit with additional desiccant, seals, etc.
