I have to find mine, I have one like that somewhere here also but not been running much for air tools since I got the last compressor. Those normally work ok.
I drain my tank often also, but I have lots of humidity here and I am overloading on the filter systems
The air tools like impacts, ratchets, cutters, grinder and drill, I don't care so much about, one filter is good enough and I keep those oiled also.
Anything that effects paint, powders, blasting media, etc.. though I figure never too many filters! Even the blow gun for blowing off parts before painting or coating I don't want any trash in the air.
