Fox x 4...this is one case where bigger is better!
I have a BIG Quincy single stage, two cylinder, pressurized oiling system with unloaders and a 5hp motor that is on a 60 gal tank. I have the pressure switch set at 125 pounds and I've been running it for 20+ years (it was used when I got it), sand blasting, cabinet blasting, tools, painting etc. If I had to buy a new one I'd get the two stage because of the higher pressures they can maintain.
