Not exactly sure what you mean by hoist tank. The compressor I use is my shop Dewalt and it runs when I have it hooked up because of bleed down in the connection fittings (not on the water trap or input to lift fitting side). The max is 125 psi, they recommend 75 ish psi, can't remember if they call out a cfm, doubt it. Bendpak used to sell an "air station" that was mounted on the column but I think they had issues so were discontinued. Maybe a small tank compressor mounted on the column might be a better arrangement as I'll want to use air while the car is on the lift.
