Rheem-Ruud 70-21858-06 Fan Blade

If you are servicing a Rheem or Ruud condenser and pulling a 70-21858-06 Fan Blade from your truck, you know exact specs are non-negotiable for maintaining static pressure and compressor longevity. This HVAC replacement fan blade is a precise 22-inch diameter component with a 21-degree pitch, specifically engineered for counter-clockwise (CCW) rotation. Designed with a dual-blade configuration, it minimizes vibration and mechanical stress on the motor bearings. The 1/2" bore is located on the intake side, ensuring a secure fit on standard condenser fan motor shafts. As a veteran tech, you'll recognize this as the direct cross version of 70-21859-06, making it a versatile OEM HVAC part for several generations of outdoor units. Whether you’re dealing with a bent blade from storm debris or a hub failure, this 2-blade condenser fan restores factory-spec airflow to keep head pressures within an acceptable range and prevent premature system fatigue.

• Precision Airflow: The 21-degree pitch is calibrated to maximize CFM while maintaining high energy efficiency.
• Direct OEM Compatibility: Serves as a drop-in replacement for Rheem 70-21859-06 and North American HVAC models.
• Balanced Design: The 2-blade geometry reduces centrifugal runout, protecting your motor’s shaft and seals.
• Durable Construction: Heavy-duty materials resist the warping and corrosion typically found in coastal or high-humidity environments.

• How do I confirm rotation? This blade is CCW (Counter-Clockwise) when viewing from the discharge side. Always check your motor's nameplate before installation.
• Will this fit a 5/8" motor shaft? No, this blade features a 1/2" bore. Attempting to bore out the hub will throw the blade out of balance.
• Can I use this for the 70-21859-06? Yes, this is the designated direct cross-reference part for that older number.
