Review on NANPU 1/2" NPT Compressed Air Filter Regulator Lubricator Combo Water/Oil Trap Separator - Gauge(0-150 Psi), Poly Bowl, Semi-Auto Drain, Bracket - 3 In 1 Two Unit by Emmanuel Winschel

This is the best regulator that i've had the chance to use, it's accurate, maintains pressure and so far haven't had any issues with leaks. I am very pleased with this regulator. During the install I needed to reverse the filter and dryer to accommodate the piping in my garage and it was an extremely easy process to do so. The only drawback that I've noticed is that the dial is extremely tiny and as someone who has bad eyes it can be a challenge to read in poor lighting. Overall, I am very pleased with this regulator.
