The Lennox 27K78 is a 10-Inch replacement fan blade specifically designed for unit heaters. Crafted from durable steel, this blade ensures efficient and reliable operation within your heating system. Unit heaters work by drawing in cool air, heating it through a gas burner or electric element, and then distributing the warm air throughout the space. The fan blade plays a critical role in this process by rotating and forcing the heated air out of the unit. This Lennox blade features a 27-degree pitch, which is optimized for optimal airflow in unit heater applications. The fixed hub on the discharge side allows for secure attachment to the unit heater's motor shaft. With a weight of 1.46 pounds, the 27K78 is a lightweight yet robust replacement blade that contributes to efficient and consistent warm air distribution in your unit heater.
