Valeo Ventilation Blowers Air conditioning for Passenger Car

Ventilation Blowers

What is a blower?

The air conditioned air that enters a car’s cabin is propelled by a motor driven fan, known as a blower. The blower module is located inside the Heating Ventilation Air Conditioning system (HVAC).

Parts of a blower

A ventilation blower consists of:

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

How does a blower work?

A ventilation blower uses the correct amount of thermal power from the heat exchangers to achieve the desired flow rate. A blower is also designed to monitor the heat loss in the air conditioning circuit, in order to set the pressure.

The importance of the blower

The ventilation blower ensures efficient air flow in the cabin. It is a key component for passenger comfort and safety. It is the blower’s responsibility to demist the windscreen for example. Most vehicles, including those without air conditioning, are equipped with a blower.
