Since I am moving my shop down to my basement I need a compressor. We have a 60 gallon cambell hausfeld in the current shop that puts out something like 10.2 scfm at 90 psi, but one of the cylinders is broken so really it is half of that. I need something that can run a harbor freight hvlp gun, and the pneumatic powered blast gates for my cyclone. I would think that the blast gates use less air than the hvlp. I have an old compressor but i think that the tank is past its safe use. Would it be rediculous to buy a smaller compressor and hook it up to the old compressor? Any sugestions?
