Reznor 96379 Fan Blade

The Reznor 96379 Fan Blade is a critical engineering component designed for high-static efficiency within Reznor unit heaters and air handlers. For contractors servicing FE 75BTU heating units, this OEM replacement fan blade provides a precise 12-inch diameter 3-blade configuration engineered to move high volumes of air while minimizing motor stress. The hub is machined for a 3/8-inch bore, ensuring a secure, concentric fit on the motor shaft to prevent vibration and premature bearing wear. This specific model features a clockwise (CW) rotation, which is essential for maintaining the correct airflow across the heat exchanger to prevent limit-tripping or overheating. Fabricated from heavy-duty materials, the 96379 heater part is built to withstand the thermal cycling and continuous duty cycles of commercial HVAC ventilation systems. Proper pitch and balancing are factory-set to reduce operational noise and optimize peak static pressure, ensuring your client's system maintains consistent temperature control and energy performance throughout the heating season.

• Factory-Balanced Geometry: The 3-blade design is OEM-precision balanced to eliminate mechanical vibration and extend the service life of the fan motor.
• Optimized Airflow Profile: Engineered specifically for Reznor HVAC equipment to ensure proper heat dissipation and system efficiency.
• Industrial-Grade Construction: Built to handle the rigorous environments of unit heaters, resisting deformation under high-temperature conditions.
• Direct Bore Compatibility: Features a standard 3/8" bore for a seamless slide-on fit with factory motor shafts, reducing field labor time.

What is the correct rotation for the Reznor 96379?
This blade is designed for clockwise (CW) rotation. Always verify the rotation of the existing motor before installation, as an incorrect rotation will reverse airflow and potentially damage the heat exchanger.

Will this fit any 12-inch heater fan?
While it is a 12-inch diameter blade, it is specifically hub-indexed for the Reznor 96379 specification. Ensure your motor has a 3/8-inch shaft and that the unit requires a 3-blade assembly for proper performance.

How do I ensure a secure mount on the motor shaft?
The 3/8-inch bore includes a set screw. Ensure the set screw is tightened against the flat portion of the motor shaft to prevent slipping and maintain mechanical integrity.
