The Constant Airflow Control is used to monitor velocity pressure in a system, automatically adjusting the fan speed to maintain a desired velocity pressure (constant CFM). This control reduces energy consumption not only by reducing the speed and the energy used by the fan, but will also reduce the amount of conditioned air that is exhausted. Recommended for use in multi-family structures, hotels and schools where demand control ventilation applications exist.

The Vari-Green transformer provides a 24-volt power source from the existing line voltage at the fan to the motor and controls. It has two dry auxiliary contacts (one normally open and one normally closed) available to signal a motorized damper or interlock with other devices.
