The PennBarry 56344-0 motor is a multi-speed electric motor found in HVAC equipment, particularly exhaust fans and blower fans. These fans play a critical role in moving air throughout the system. In exhaust fans, the motor helps remove combustion gases from the furnace by spinning the inducer fan within the flue pipe. Blower fans, powered by this motor, circulate conditioned air throughout the ductwork, delivering warm or cool air to your home depending on the season.
