Broan S99020144 Blower Wheel 1/4" for Ventilation Fan

The Broan S99020144 Ventilation Fan Blower Wheel generates the airflow required to move air through the ventilation fan housing and toward the exhaust passage. Driven by the connected fan motor, its rotating blades draw air into the wheel and direct the moving stream through the unit. The 1/4-inch specification identifies the shaft or connection dimension associated with the wheel assembly, depending on the fan configuration. Its operation works directly with the motor and surrounding housing to maintain the intended air movement during fan operation. Within the ventilation unit, the blower wheel provides the rotating air-moving movement required for exhaust circulation.
