The passenger compartment fan assembly is used to vary the rate at which air is blown into the passenger
compartment, depending on the requirements of the customer.
– Cooling fan assembly:
The cooling fan assembly motor is normally used in order to promote heat exchange in the condenser and
therefore improve the performance of the air conditioning system. Activation of the air conditioning fan unit
depends, among other things, on the vehicle speed and high pressure in the loop.
– Air pipes:
The air flows into an open air inlet scoop towards the exterior. Therefore there must be enough air flow for it
to be channelled into the passenger compartment. This flow can be created by the vehicle speed (in non-
recirculation mode) or by activating the blower. The air flowing into the passenger compartment is protected
by a grille and a rain shield in order to prevent foreign bodies and water from entering. The air is then
distributed inside the passenger compartment.
