range hood exhaust fan?

Has any one ever found a motor replacement that is considerably quieter than the normal exhaust motor in the range hood? I cook a ton when I fish and camp and after a while that fan will drive us out of our minds. I've taken some advice and tried to use the roof exhaust but it doesn't work all that well. I'm looking for just replacing the motor not the disassembly of the whole unit sort of a plug and play if there is such a thing. Thanks in advance, Joe

  • I installed a 6" computer fan and it is very quiet now. Make sure that the one you get is 12 volts.
  • OK, I can definitely replace the fan blade and run the PWM controller.
    How about these?

    This is what's on there.

  • Fans will be always noisy.
    Observe that high-end household hoods use blowers instead. Those are much quieter, but rebuilding factory hood to accommodate blower would make whole project.
  • YES, adding a PWM controller is about the best for reducing fan speed & noise and still maintain enough air flow to evacuate. I replaced our 18 year old motor and blade which was slightly quieter but it was adding the variable speed controller that made it not so atrocious.
  • Noise is a combination of motor, fan blades and exhaust chamber. The shape and size of the fan blades is typically the biggest factor. Maybe look at a variable speed control for your current motor?
