109421 Febi Interior Fan Assembly

The Interior Fan Assembly from Febi (MPN: 109421) is sourced from China and has supplier-listed dimensions of 200 x 215 x 215 mm. It is typically used within the HVAC > Blower Motor category of automotive replacement parts. Dimensions are provided by the supplier and may include packaging dimensions. Blower motors are centrifugal fans responsible for forced-air circulation through a vehicle’s HVAC system. Typically located within the HVAC housing, these motors draw ambient air across the heater core or evaporator core and distribute it through vents. Operation relies on an electric motor driving a multi-bladed fan wheel; speed is often controlled via PWM signal or resistor-based voltage reduction. Modern units frequently incorporate variable-speed functionality for enhanced comfort and efficiency. Failure modes include motor burnout, fan wheel damage, or control module malfunction, resulting in reduced or absent airflow.
