Rheem-Ruud 70-18629-01 Blower Wheel

The Rheem-Ruud 70-18629-01 Blower Wheel is a precision-engineered OEM replacement blower wheel designed for high-static pressure HVAC applications. Measuring 10 5/8" diameter x 10 5/8" wide, this assembly features a 1/2" bore sized for standard direct-drive motor shafts. As a double inlet blower wheel with 48 blades and a concave disc, it provides balanced airflow distribution and reduced vibration in high-demand furnace and air handler cabinets. This unit utilizes clockwise (CW) rotation (facing the hub) and serves as the direct replacement for 70-20218-03, ensuring HVAC part compatibility without field modifications. Whether you are performing a routine Rheem blower motor repair or correcting a noisy assembly, this 10x10 blower wheel delivers the aerodynamic efficiency required for optimal system performance. Designed for durability in residential and commercial units, it features a single set screw for a secure mechanical bond to the shaft, maintaining critical clearance and airflow across the evaporator or heat exchanger.

• OEM Compatibility: Serves as the factory-authorized 70-18629-01 direct replacement for the discontinued 70-20218-03 part number.
• Enhanced Airflow: The 10 5/8 inch double inlet design and 48-blade configuration maximize CFM output and static pressure handling.
• Precision Balance: Features a concave disc and robust construction to minimize axial runout and prevent premature motor bearing failure.
• Direct Drive Ready: Integrated 1/2" hub with set screw allows for immediate mounting on standard HVAC blower motors.

What is the correct rotation for this wheel?
This is a CW (Clockwise) rotation wheel when viewed from the hub side. Always verify the rotation of your existing motor before installation.

Does this wheel include the set screw?
Yes, this centrifugal fan wheel comes with the manufacturer-standard set screw required to secure the 1/2" bore to the motor shaft.

Will this fit my specific Rheem or Ruud unit?
This 10.625" x 10.625" wheel is standard in many 10x10 nominal blower housings. If your current part is 70-20218-03, this is the correct technical update.
