So you want to use the motor as the compressor itself? Not to power a separate compressor? I would use the motor to power a multi horsepower purpose built air compressor head first.
I know people have turned compressor heads into simple motors so it is feasible. You would have to find a way to get the compressed air from the head, I wouldn't think the manifolds would hold pressure well. And what would you use to power the motor used as a compressor another motor?
