After (fresh) air has been cooled or heated, it needs to be delivered into the car cabin on demand. Cabin blower fans are the component that performs this function. With an impeller and electrical motor, they generate a flow of air that passes through the evaporator and/or heater core to raise or lower the cabin temperature.
The flow of air into the cabin is controlled either manually by the driver or passenger(s), or automatically when the vehicle is equipped with climate control. All DENSO cabin blower fans are manufactured to the highest OE quality standards, with a comprehensive range ensuring maximum coverage of vehicles and applications.
