I was looking at sandblasters and many require 15 cfm at 90 to 100 psi. Is all that really needed? Or is that a rating affixed for maximum possible removal? I could get my hands on a fairly decent compressor, 8cfm at 90psi. This is a 3 hp machine with a large tank. Too big for my space as it is (but I could make room )
Thanks
sandblaster cfm requirements?
Jeff,
Don't bother with anything other than a two-stage, 5hp+, 80 gallon compressor. It will set you back a few more bills, but it will be a good investment. 60 gal is simply too small for what we need them for. Although it can work, it will be a big headache and you will have upgradeitis from the moment you begin blasting and hear that compressor run for 30 minutes or more without stopping. That's not to mention the heat generated and radiated by it. Buy the best you can afford, even if it means buying used.
Best,
Jeff
