I was wondering if this compressor would push a D/A sander? I know they take a lot of cfm but i don't know how to find out how much this compressor puts out.

D/A? That'd be duckass? Sorry just not familiar with the term. Air files and jitterbugs do take a lot of air . . . Ah, D for disk? No matter, still takes a lot of air. If this thing is old the HP rating is probably conservative. By your description of it, its got as fair sized tank. If the pump has twin cylinders and you have good air storage capacity, you should be in business.

I have a 3hp compressor with a 20 gallon tank which runs on 220 volts. I also have three air files. One is Taiwanese junk which has been stripped for parts. The second is a new Coleman "Air Force." The third is a Chicago-Pneumatic purchased at a used tool shop for $10. It had a bad valve from too much exposure to solvents.

After replacing its valve the CP has proven to be the only file of the three that will work continuously with this compressor. The others draw significantly more air and do less work with it. My point, the air tool may be the biggest variable determining whether this compressor will work for you.
