Force Ventilation Fans

Forced ventilation fans, sometimes known as FV fans, force vent fans or force vent units, are a cooling device that fits onto the non-drive end of an AC electric motor.  No matter the motor speed, a force vent fan provides constant cooling air across the body of the motor; keeping the motor cool whilst operating at low speeds.  This is because when you are using a motor at a lower speed, it is unable to pass enough airflow over itself to cool down.  We recommend using a force vent fan if you are using a motor with an inverter, which means your motor will be running at speeds of 50% or less for prolonged periods.
