DA Problem

I agree, most any compressor with 5hp or larger should have adequate cfm. My Quincy has a 7.5hp and puts out 22.6cfm @ 175psi. It will run a DA all day long without batting an eye. Im just curious of the specs on his compressor are.
I have seen 6hp single stage compressors before. A safe rule of thumb when buying an air compressor is to get the biggest one you can afford and your electric will support. For me I couldnt go any bigger because of the electric demand. This one pulls a whopping 80-90 peak amps when it starts up!
