A compressor for a blast cabinet will need a LOT of CFM and the compressor really should have a 100% duty cycle because it will run a lot. The CFM required will be determined by the size of the blast nozzle and the air pressure regulator setting but even with a relativity low pressure and a small nozzle the air flow requirement will still be high, it's just the nature of the beast. Basically you will be concerned with CFM first (that will be your main concern!) and duty cycle second plus the over-all quality of the outfit, while it's tempting to want the largest tank you can get it's not really all that important and if the other two requirements are there (CFM and Duty Cycle) then the HP and tank will be sized properly by the manufacturer, whatever else you do DON'T pass up higher CFM to get a bigger tank because contrary to popular belief a bigger tank does not make up for lack of CFM!
