Hromee 1/4 Inch Air Compressor Filter Regulator Combo, Water Oil Separator with Pressure Gauge, Manual Drain, Ball Valve and Bracket AW2000-02

I purchased this after buying a plasma cutter to keep the air required clean and oil free. Set up was a breeze. The ports on here are 3/8" NPT. The unit works as advertised and it saves my consumables. Precise psi adjustment is easy and accurate.

Works great, well built

First regulator/trap I've got that doesn't leak, which is surprising with a double trap. Even the one that originally came with the compressor leaked. This one has been able to maintain pressure even with the compressor turned off for a couple of days. Impressive.

So far it works as intended. As of lately I’ve been having problems with my air compressor spraying out water but I drain my tank and leave the drain open until I get ready to use it but it’ll still blow out water. I put this nice little gadget on and I sprayed the blower until all the water wouldn’t spray no more and i haven’t had any problems with water blowing out since then. When I say water, I mean a little moisture. It’s very easy to install and definitely worth having.

I bought a couple of these and added them to my compressor for painting mid-size projects, mostly motorcycle restorations. Good value for the price and quality. Had them for a couple years now and no issues.
