AC Fan

An important player of the air conditioning system

The fan plays an important, supportive role for the effective operation of the engine cooling and climate systems of the vehicle. In the climate system, the AC fan forces air through the condenser. 

High operation pressures inside the condenser and the temperature produced by the condensation process require an additional air flow supporting the heat exchange between the ambient air and the refrigerant inside.  Cooling produced by the fan is crucial for proper condenser operation.

Technical Details

A nonperforming AC fan has a very negative impact on the condensation process inside the condenser thus the entire AC system performance.

As an electrical device, the fan is often exposed to failure due to problems with the vehicle’s electrical system, e.g. overvoltage, bad fuse, nonperforming alternator.

Depending on the vehicle application, the AC fan can be engaged by means of: pressure switch, indirect connection to the compressor clutch, the vehicle’s Electronic Control Module (ECM) or signals sent from the AC-ON button.
