Minimum Air Compressor

The biggest lie out there are brands that rate at ZERO PSI......and a LOT of them do. Like Del said, get the highest CFM @90 PSI and the biggest tank you can afford. I Frankensteined my big shop compressor a few years ago. I got a H/F (I know) 2 cylinder pump, a 7 HP 220V motor and mounted them on an older Kellog American 120 gallon horizontal tank after I derusted it and coated the inside. It works good with a 175 PSI regulator on it. It keeps up with my blasting cabinet as well as my 110 pound sand blaster. If your compressor will pump up, turn off and cycle all over again while you're using your biggest CFM hog, you got enough compressor. Mine does just tat.
