Lennox 13K13 Blower Wheel

The Lennox 13K13 Blower Wheel is a critical 13-3/16-inch diameter by 12-5/8-inch width component engineered for precise HVAC airflow optimization. As a genuine Lennox OEM replacement part, this belt drive blower wheel is built to maintain the specific static pressure requirements of commercial and residential package units, including the CHA16, CHA24, and GCS24 series. The 13K13 is technically identical to Lennox 13K1301, ensuring a direct drop-in fit for technicians performing furnace blower wheel replacement. Featuring a 1-inch bore with a double hub and two square head set screws on each side, this 43-blade wheel is factory-balanced to eliminate vibration and reduce mechanical stress on the motor and bearings. Utilizing a high-strength construction, it effectively restores centrifugal force within the blower housing, preventing common issues like short-cycling or insufficient heat exchange. For contractors, prioritizing genuine Lennox parts ensures seamless integration with existing drive pulleys and consistent CFM delivery across all cooling and heating cycles.
