Review on NANPU 1/2" NPT Air Drying System - 5 Micron Particulate Filter, 0.01 Micron Coalescing Filter, Air Pressure Regulator Combo - Semi-Auto Drain, Poly Bowl W/Metal Gauge by Sonny Nevers

I was having major moisture issues with my air supply. I installed this setup and that has virtually eliminated my problems. I've been running it for a few weeks and the only time I've gotten moisture was when I didn't drain the bowls soon enough. I do wish the bowls were a little larger. They work well to trap moisture but fill up quickly for me. That said, if I make sure to drain them once or twice a day, they are fine.The worst problem I had is that they missed something when making mine. Namely there is a port for Pressure Gauge to attach to on the Regulator. However it wasn't drill through. It WAS drilled and tapped for the gauge, but there was no hole into the air passage. So the gauge wouldn't read any pressure until I drill a small hole myself. That was the ONLY problem I've had with this setup. Well that and the lack of ANY instructions.Would have rated this 4 or maybe even 5 stars due to the Price and How well it works, but the fact that they missed drilling a very important hole is a pretty big strike against them on this one.
