i NEED a blasting cabinet. i looked at harbor freight and all of them require 10 CFM at 90 PSI. that's a lot of CFM. i don't want to have to buy a $1000 compressor too. does anybody know of a blasting cabinet that will operate at lower CFM? i'll have to check but i think my compressor only pumps out 4-5 CFM at 90 PSI.
