Review on NANPU DFR-04 1/2" NPT Air Drying System - Double Air Filters, Air Pressure Regulator Combo - Semi-Auto Drain, Poly Bowl by Matthew Sutton

Bought this to add to my water separation system on my air compressor, this didn't catch any water while it was on my system I had 2 more separators set up past this unit, the separator next to this caught a lot of water that went right through this pos and I have one final separator at the end of my air hose that attaches to my hvlp sprayer that caught any remaining water that the first 3 didn't. After 2 weeks of use the diaphragm popped and now has a hole in it that constantly blows air, the pressure adjuster was not accurate at all, overall a waste of money and time. I do not recommend this unit even in a pinch you won't have any improvement over running without a separator. Spend a little more on a larger unit made by a company that cares about their reputation.
