Review on NANPU 1/2" NPT Air Dryer System - 5 & 0.5 Micron Filtration, Pressure Regulator, Water Trap Separator, Semi-Auto Drain & 150 Psi Gauge W/ Poly Bowl & Metal Bracket by Joel Gumbiner

I really wanted to like this filter setup, it seemed very well built. It worked for about 2 days, then it started leaking. Turned out the diaphragm popped out of the housing. I was able to fix it, but less than a day later it happened again. I think the machining job was poor and there just wasn't enough clamping pressure to sufficiently hold the diaphragm.When I reached out to support to ask for a replacement part, all they offered was for me to return it and buy another. So don't expect any support nor warranty once the amazon return window closes.
