Rheostat with a Gable Fan?
I have a gable fan that is very loud. I'd like to slow it down via a
rheostat/potentiometer. Is this possible? Is it advisable? If so, can anyone suggest a rheostat that is adequate for the job? TIA |

If so, can anyone suggest a rheostat that is adequate for the job? It is going to depend on the type of motor used in the fan. Don't try a light "dimmer". They are not designed for motor control. Is it direct drive, or belt driven? If belt driven, you could change pulley sizes to change the speed. Bob |

If so, can anyone suggest a rheostat that is adequate for the job? TIA Many fractional HP motors can be controlled by a rheostat, similar to a light dimmer switch. Be sure you have one that can handle the HP of hte motor. |

Be sure you have one that can handle the HP of hte motor. Every AC motor that would be used in a gable fan that I have ever seen is fixed speed and determined by the freq of the AC source driving it. You can't slow it down by lowering the voltage with a rheostat, which wouldn't be very good idea to begin with. You;d just be dissipating energy as heat. Either get a quiet new fan or maybe switch to a passive ridge vent system. |
