Rheem-Ruud 70-21858-15 Fan Blade
When you are onsite for a repair, a failing Rheem-Ruud 70-21858-15 Fan Blade can lead to inefficient airflow or severe vibrations in the condenser. This 17.75" diameter fan blade is a direct OEM replacement fan blade designed to restore factory-spec static pressure and heat transfer efficiency. Constructed with a 27 degree pitch, this 2-blade assembly is engineered for CCW rotation (counter-clockwise) and features a standard 1/2 inch bore on the intake side. This specific configuration is common in many Rheem and Ruud residential and commercial outdoor units where airflow management is critical. Using a genuine 70-21858-15 fan blade ensures the balance matches the original motor's torque profile, preventing premature bearing wear. This is a technical component meant for professional installation in HVAC condenser fan blade replacements to maintain operational integrity across varied ambient conditions and high-demand cooling cycles.
Key Benefits- OEM Compatibility: Precision-engineered for Rheem-Ruud outdoor condensing units, ensuring a seamless fit without hub modifications.
- High-Efficiency Airflow: The 27 degree pitch is optimized for maximum CFM delivery while maintaining a manageable amp draw on the motor.
- Balanced Performance: Factory-set 2-blade design reduces mechanical stress and vibration, extending the life of the fan motor.
- Industrial Build: Durable construction resists the typical warping and surface corrosion found in older or universal-fit replacement fan blades.
- What is the rotation for this blade? This unit is specified for CCW (Counter-Clockwise) rotation when viewing from the intake side.
- Does this include the hub or set screw? This axial fan blade features a built-in 1/2" bore designed to slide directly onto the motor shaft for standard set-screw mounting.
- Can I use this on other brands? While technical specs like the 17.75" diameter and 1/2 inch bore might match, always verify that the 27 degree pitch and weight are compatible with your specific motor's horsepower rating.
