Actuators & Resistors

To keep drivers and passengers comfortable, the HVAC system’s actuators and resistors need to run efficiently.

Actuators & Resistors

How they work

To make sure the right amount of cold and hot air enters the cabin, the HVAC system needs to run efficiently. High-quality actuators and resistors achieving this by controlling the flow of air into the cabin.

Actuators control the airflow within the HVAC system itself and help regulate the mixture of hot and cold air by sending it to the required position within the passenger cabin. Resistors have a similar function, but instead of controlling the temperature of the air, they control the power of the airflow via the cabin blower fan speed. This means the driver can easily adjust the speed of the blower fan according to their needs.
