    Ventilation blowers

    The air in the cabin is propelled by a motor driven fan, more commonly known as a blower. The blower module is located inside the HVAC.

    It consists of:

    • A fan
    • A drive motor
    • A power control device

     

    The blower is designed on the basis of:

    • The thermal power to be drawn from the heat exchangers in order to achieve the right flow rate
    • The heat loss in the circuit, in order to set the pressure.

     

    The blower ensures efficient air flow in the cabin. It is a key component for passenger comfort and safety by demisting the windscreen for example. The blower must be replaced after a crash. Most vehicles are equipped with a blower, including non air conditioned vehicles One out of every two vehicles produced in Europe is equipped with a Valeo blower
