Hoping someone can provide some advice. I'm planning to build a bead blast cabinet for occasional use. I've had experiences using low end cabinets driven by 2hp (true 2hp) that don't have enough air, siphon systems that don't siphon, etc. Felt like sandblasting with an air brush.
What's the best way to match things up and get the most blast from the limitd air I have available (about 13-14 cfm)? I was planning to buy one of the cheap Sears portable siphon sandblasters and use that for the gun.
I have two compressors. One is an Emglo contractor type 220 volt rated at 13.5 cfm at 125 psi and 13.8 cfm at 100 psi. Small tanks on this, but 4 cylinders single stage and reputed to have accurate cfm rating. Motor is only 3hp, but it's huge, compressor rated 1.2 or so duty cycle, and Emglo suggests a 30amp 220 volt circuit. I can keep the air fairly dry, though a long run of 3/4 copper pipe, a drain, and a filter. The other compressor might possibly be worth piping in, but it's only a cheap 3-4 cfm portable. Probably not worth the effort, unless there's a magic gun that wants 15 cfm instead of 13?
Any suggestions to match things up?
