Lennox 21703 Wheel

When you are dealing with a critical airflow issue in a high-capacity system, the Lennox 21703 Blower Wheel is the direct OEM replacement fan wheel engineered to restore factory-spec HVAC performance. This double inlet centrifugal wheel features a precise 12-5/8 inch diameter and 12-5/8 inch width, designed specifically for a 5/8 inch bore shaft. Constructed from heavy-duty galvanized steel, this forward-curved blower wheel is built to handle the static pressure requirements of Lennox B10-65-1P models and similar commercial grade air handlers. As a technician, you know that keeping the blower motor assembly balanced is essential to preventing premature bearing failure and excessive cabinet vibration. The Lennox 21703 ensures dynamic balance and optimal CFM delivery, making it the reliable choice for maintaining system integrity in the field. This HVAC blower wheel replacement provides the exact geometry needed for high-efficiency heat exchange and consistent airflow across the evaporator or heat exchanger.

• Direct OEM Fit: Engineered as a genuine Lennox 21703 replacement, ensuring zero-clearance issues during installation in supported cabinets.
• Industrial Durability: Crafted from corrosion-resistant galvanized steel for long-term structural stability under continuous operation.
• Optimized Airflow: The 12.625 x 12.625 forward-curved blade design maximizes HVAC blower assembly efficiency and air distribution.
• Vibration Reduction: Factory-balanced to minimize mechanical stress on the blower motor and reduce audible noise levels.

What is the exact bore size for the Lennox 21703?
This wheel is manufactured with a 5/8 inch bore to match specific high-torque blower motor shafts common in larger Lennox units.

Which direction does this blower wheel rotate?
The Lennox 21703 is designed for clockwise (CW) rotation when viewing from the hub or bore end of the wheel.

Can I use this for non-Lennox applications?
While designed for Lennox equipment, it can function as a universal blower wheel replacement if the dimensions, 5/8" bore, and CW rotation match your existing centrifugal fan specifications.
