Air compressor

  1. Mar 30, 2008 #1
    If I have an air compessor that uses an 11 horse power gas engine.
    How do I know what size electric motor, and what RPM will do the same job?

    Can't you just match the horsepower and rpm to the one you have?

    Electric motors are often sized in H.P. They do however provide much more power at lower rpm than do gas engines. I would suggest you look for a compressor duty motor. Try Grainger, Mcmaster Carr or Northern Tool. 11 h.p is pretty big for a home air compressor. Will you be able to connect it to a 220V source? Even at 220V you will need almost 40 amps.
