Reznor 208976 Fan Blade

The Reznor 208976 Fan Blade is a critical OEM replacement component designed for high-static air movement in commercial and industrial HVAC applications. This 24-inch diameter fan blade features a precision-engineered 34-degree pitch across a 5-blade configuration, optimized to maintain consistent CFM levels while minimizing operational vibration. Built for durability, it utilizes an aluminum blade construction with a robust steel spider to ensure structural integrity under the high rotational stresses typical of larger Reznor unit heaters and air handling assemblies. With a 5/8-inch bore, this axial propeller is designed for a secure fit on standard motor shafts, facilitating a direct swap that restores factory-spec airflow and heat exchanger efficiency.

Key Benefits:

• OEM Precision: Guaranteed 24-inch propeller sizing and 34-degree pitch ensure internal static pressure remains within design tolerances.
• Enhanced Stability: The 5-blade design reduces harmonic resonance and bearing wear on the blower motor by providing a balanced rotational mass.
• Corrosion Resistance: High-grade aluminum blades prevent oxidation, extending the service life in demanding mechanical room environments.
• Direct Fitment: Standard 5/8-inch bore diameter and set-screw mounting allow for rapid field installation during routine preventative maintenance.
• Optimized Performance: Engineered specifically for Reznor HVAC equipment to restore peak heating and ventilation output.

Common Questions:

How do I verify the rotation for this fan blade?
Rotation is typically determined by looking at the discharge side of the blade. For the Reznor 208976, ensure the pitch matches your existing assembly to maintain proper airflow across the heat exchanger and avoid motor overheating.

What are the signs that my HVAC fan blade needs to be replaced?
Visible stress fractures on the spider, rhythmic vibration, or excessive noise during the start-up cycle indicate the blade is out of balance or nearing failure. Replacing a compromised blade early prevents catastrophic damage to the motor and shaft.

Will this work with a 1/2-inch motor shaft?
No, this unit is specifically machined with a 5/8-inch bore. Attempting to use a bushing or forcing a fit on an undersized shaft will cause dangerous imbalances and lead to premature component failure.
