Lennox 21793 Blower Wheel
Replace a failing or unbalanced Lennox 21793 blower wheel to restore peak volumetric efficiency in residential Lennox air handlers and furnaces. This 12 5/8 x 9 1/2 blower wheel features a 1/2 inch bore size and is engineered for clockwise (CW) rotation when viewing the hub end. Constructed from heavy-duty galvanized steel, this double inlet direct drive wheel utilizes 43 precisely spaced blades to ensure quiet, stable operation at speeds up to 1200 RPM. As a genuine OEM Lennox replacement part, it provides exact fitment for CBA27UHE, CBX27UH, and CB31MV series units, eliminating the vibration and motor strain caused by generic alternatives. When the blower assembly begins squealing or showing signs of hub shearing, replacing the squirrel cage is critical to prevent total motor failure and maintain calibrated airflow across the evaporator coil. This HVAC blower wheel replacement is the industry standard for maintaining static pressure requirements in multi-speed and variable-speed Lennox systems.
- OEM Compatibility: Validated for use in Lennox CBX32MV, CB27UH, and CBX27UH air handlers.
- Precision Balancing: High-grade galvanized steel construction minimizes shaft runout and extends motor bearing life.
- Technical Specs: 12 5/8" diameter by 9 1/2" width with a standard 1/2" bore for seamless direct drive integration.
- Performance: Optimized for clockwise rotation with a convex hub design to maximize CFMs and system efficiency.
Common Questions
How do I know if I need a Lennox 21793 replacement?
Listen for high-pitched squealing or "thumping" sounds. Inspect the blower for sheared hubs or bent fins, which often occur due to debris buildup or age-related fatigue.
Is this a direct drive or belt drive wheel?
This is a direct drive blower wheel designed to mount directly onto the 1/2" motor shaft using a standard set screw. It is not compatible with belt-driven assemblies.
What is the correct rotation for this part?
This part is specifically Clockwise (CW) rotation. Ensure your motor moves in the same direction before installation to prevent airflow reversal or performance drops.
