NANPU 1/4" NPT High Pressure Compressed Air Filter Regulator Lubricator Combo Water/Oil Trap Separator - Gauge(0-230 psi), Poly Bowl, Semi-Auto Drain, Bracket - 3 in 1 Two Unit

This was perfect for what I needed on my set up. The oiler is the only reason i give it 3 stars. The oiler is large enough that i don't have to continually fill it and i can adjust the flow easily. I installed it in a box protected from the weather at the corner of the house giving me access to unregulated air and regulated / oiled air in my driveway without having to run 100' of air hose. Worked great for about 4 months. The leak developed at the screwed fitting for the water holder bypassing the o-ring seal. I replaced the oring and it still leaked, I tried sealing the threads and using an o-ring lube on another new o-ring, still leaks. I replaced it with a regulator and will buy an oiler that I can connect to my hose reel for my air tools. disappointing to waste this much money for only 4 months of occasional use.

Look well made and rugged. No real instructions on where to put the gauge. A lot smaller than depicted.The gauge goes as depicted on side with arrow after removal of plug on the regulator. The square with the big blue knob that adjusts the pressure.

Works fine but initially found air leak because 2 places to pick to put gage and instead of a metal plug it is plastic.

It mounted and adjusted easy but once the oil run out there was no way to remove the oil tank to refill it., which made it useless.

Just got done installing.This thing leaks from the top where the regulator attaches to the black ring. Very ticked off.

Gauge came broken..

So far works just as described. Very good product.

Well made and reasonably priced
