Some of you say you do it so I believe you, but I'm really surprised that a small compressor will drive a blasting cabinet.
I used to have a medium sized cabinet and it needed 8 cfm @100 psi for continuous duty. That's like two stage twin cylinder 4-5 hp in 220v. It needed continuous duty to glass bead something like a cylinder head or an exhaust manifold. I guess gun parts are smaller and don't need continuous duty? Maybe the orifices are smaller on the smaller blast cabinet guns?
I would think that the blast cabinet owner's manual would spell out how much air it needs - mine did. ?? I'd match the compressor to that.
$.02
PS I have two Speedaire 220v compressors and plugs to run both at the same time. One is 4 hp and the other is 5 hp. I chain them together to blow out my 1/2 acre sprinkler system in the late fall. I also have a high-end DeVilbiss moisture trap/pressure regulator. If anyone in the Rogue Valley wants to come over and hook up a your own cabinet to do some gun parts, send me a PM.
