Wayne Combustion 21427-SER Blower Wheel 3.44" W X 4.25" OD Standard

The Wayne Combustion 21427-SER Blower Wheel is a rotating air-moving component measuring 3.44 inches wide with a 4.25-inch outside diameter, designed to generate controlled airflow within the burner assembly. As the motor drives the rotor and its balanced blades draw in and discharge air to maintain the airflow required for the combustion process. It is connected securely to the motor shaft allowing smooth rotation with proper alignment during operation. By delivering consistent airflow in HVAC systems, it supports balanced air distribution, maintains combustion efficiency, reduces airflow irregularities and ensures stable burner performance.
