Compressor Horsepower

  1. Oct 3, 2007 #1
    I have a 10 HP electric motor on a compressor. The motor goes south but I have a good 5 HP electric motor. Will it work? I am sure I could not get the PSI that the 10 horse produced, probably have to reduced the hi shutoff.

    Horsepower has a torque/time value. At 5 hp you might have to work with pulley ratios to get it running, especially when pumping into an already pressurized tank or load. The psi should be the same. Time to fill a given volume to a given psi will be increased. That's how those little cigarette lighter powered air pumps for your car work. Same psi but takes longer to fill the tire.
