Review on Air Filter Regulator Lubricator Combo (FRL) With Auto-Drain And Water/Oil Trap Separator - 1/4" NPT, Gauge (0-150 Psi), 5 Micron Brass Element, Poly Bowl, Metal Bracket By NANPU by Joshua Gaines

I can’t remember what I liked, but I do remember what I don’t like. No manual/directions . No clear easy was to phone vendor to get help. Right out of the box , air is gushing out from adjustment know. Gage needle moves when increasing or decreasing pressure via the plastic adjustment knob, but it sounds like there’s no o-rings or something . Nothing telling me how to get the knob off, so I’ve been out of business for 3 days now trying to figure this out . What a waist of my vault level time. No such thing as old fashion trained cust service anymore . They even make an effort not to show their phone number ( which s/be the 1st thing you see when trying to contact vendor.Price paid for buying online - no quality chks , no care from the manufacturer for their saps, I mean customers. Regret, I mean regards . . . Sean 6/23/22
