Lennox 21708 Blower Wheel
The Lennox 21708 Blower Wheel is a high-precision OEM replacement part engineered for demanding air distribution in residential and light commercial HVAC units. Featuring a 10 x 8-1/2 inch configuration and a 1/2 inch bore, this direct drive blower wheel is built to maintain tight tolerances and static pressure requirements in Lennox furnaces and air handlers. With 48 precisely pitched blades, this CW rotation blower wheel (clockwise from the hub end) ensures optimized CFM delivery while minimizing mechanical vibration that can lead to motor bearing failure. As a genuine Lennox 21708 component, it offers a drop-in fit for specific G61MP, CBX32, and G40 series models, restoring factory-spec airflow and efficiency. For technicians servicing high-efficiency systems, using this HVAC blower assembly component ensures the internal balance necessary to prevent resonant noise and premature wear on the blower motor shaft.
Key Benefits- Precision Balanced: Factory-set balance reduces vibration, protecting the motor and ensuring quiet operation.
- OEM Compatibility: Designed specifically for Lennox HVAC systems to match original airflow performance.
- Durable Construction: High-grade materials resist fatigue under high-static conditions and temperature fluctuations.
- Optimized Airflow: The 48-blade design provides consistent air circulation and maintained static pressure.
- Direct Drive Fit: Features a standard 1/2" bore with a set screw for secure mounting to the motor shaft.
How do I verify the rotation of this blower wheel?
The Lennox 21708 is a clockwise (CW) rotation wheel. For HVAC components, rotation is typically determined by looking at the wheel from the hub or motor side.
What happens if I use a wheel with the wrong bore size?
A 1/2" bore is non-negotiable for 1/2" motor shafts. Attempting to use a 5/8" or different bore size will result in catastrophic failure or inability to secure the blower wheel hub.
Will this fit my Lennox G61 series furnace?
Yes, this Lennox blower wheel is the standard OEM replacement for several G61MP models. Always check the specific furnace or air handler data plate for the required part number before installation.
