List of featured suppliers of FAN CONTROLLERS Variable Speed on Building Products Index
Fan controllers, variable speed are devices that are used to regulate the speed of fans. They can adjust the speed of the fan based on the temperature of the room or the amount of air flow that is required. These controllers are typically installed in HVAC systems to improve energy efficiency and reduce noise levels. They work by adjusting the electrical current that is supplied to the fan motor, which in turn changes the fan's speed. The speed can typically be controlled manually or automatically through a built-in thermostat or sensor.
