Rheem-Ruud 70-42268-01 Fan Blade

For service technicians requiring a reliable condenser fan replacement, the Rheem-Ruud 70-42268-01 Fan Blade is a standard-spec axial impeller engineered for high-static pressure environments. This 22-inch diameter fan blade features a 30-degree pitch and a 3-blade configuration designed to optimize airflow across the coil. Operating with a counterclockwise (CCW) rotation, it includes a 1/2-inch bore positioned on the intake side for secure attachment to the motor shaft. Constructed from durable galvanized steel and aluminum, this OEM replacement part is built to withstand the rigorous duty cycles of residential and commercial condensing units and heat pumps. When performing a HVAC motor and fan blade replacement, ensuring the correct pitch and rotation is critical to prevent motor overload and maintain system SEER ratings. This replacement fan bblade is compatible with various Rheem and Ruud models, serving as a direct substitute for legacy part numbers including 70-41799-02 and 5151-5534.

Key Benefits

• Aerodynamic Efficiency: The 30-degree pitch facilitates maximum CFM output while maintaining low acoustic levels during operation.
• Corrosion Resistance: Fabricated from corrosion-resistant materials to ensure longevity in outdoor environments subject to moisture and debris.
• Precision Balance: Factory-balanced design reduces vibration, protecting the motor bearings and increasing the lifespan of the condenser fan motor.
• Standardized Fit: Features a universal 1/2-inch bore for seamless integration with standard 48-frame and 56-frame HVAC motors.

Common Questions

How do I verify if the rotation is correct for my unit?
Rotation is determined by looking at the discharge side (top) of the fan. This 70-42268-01 model is CCW (Counterclockwise) rotation, which is standard for many Rheem and Ruud vertical discharge condensing units.

Can I use a higher pitch blade to increase airflow?
Increasing the pitch beyond the 30-degree factory specification will increase the amp draw on your condenser motor, potentially leading to premature motor failure. Always match the OEM pitch for optimal performance.

What is the proper way to install the fan blade on the shaft?
Ensure the shaft is clean and free of burrs. Slide the hub onto the shaft and tighten the set screw onto the flat portion of the motor shaft to prevent slipping and out-of-balance operation.
