Vari-Green Constant Airflow Control, Remote Transducer with Pitot Tube

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.
