Lennox 15W77 Blower Wheel
The Lennox 15W77 Blower Wheel is a precision-engineered direct drive blower wheel designed for high-efficiency airflow management in commercial and residential HVAC systems. Featuring an 11-inch diameter and 10-inch width, this OEM Lennox replacement part (replaces LB-29333BDC) provides the necessary centrifugal force to maintain consistent indoor temperatures. The 1/2-inch bore ensures a secure fit on standard motor shafts, while the CCW (Counter-Clockwise) rotation is critical for proper directional air movement in 15W77-compatible blower assemblies.
Constructed from heavy-duty galvanized steel, this wheel is balanced to minimize vibration and reduce mechanical stress on the motor. For technicians servicing Lennox KCA and KCB models, including the KCA060 and KCB060 series, the 15W77 restores factory-spec static pressure performance. This drop-in replacement is optimized for HVAC blower assembly repairs where maintaining original equipment performance and quiet operation are the primary requirements for the contractor.
Key Benefits- OEM Compatibility: Exact replacement for Lennox 15W77 and LB-29333BDC, ensuring no-mod installation.
- Precision Balancing: Factory-balanced design reduces bearing wear on the blower motor and eliminates resonance.
- High-Volume Airflow: The 11" x 10" blade configuration maximizes CFM output in high-static applications.
- Standardized Fit: The 1/2" bore size accommodates common direct-drive motor shafts used in Lennox air handlers.
What is the rotation of the Lennox 15W77?
This blower wheel is designed for CCW (Counter-Clockwise) rotation when viewing from the hub side. Always verify the rotation of your existing blower motor before installation to ensure proper airflow direction.
Which models are compatible with this 11x10 blower wheel?
The 15W77 is standard in various Lennox units, specifically within the KCA060 and KCB060 rooftop and air handler series. It is also found in select Allied, Armstrong, and Concord equipment using the LB-29333BDC specifications.
Why is a 1/2-inch bore critical for this wheel?
The 1/2-inch bore identifies the shaft diameter of the direct-drive motor. Using a wheel with an incorrect bore will result in slippage or an inability to mount the wheel, leading to potential motor failure.
