With minimal pressure drop and low noise levels the SDV controls the airflow rate of conditioned air into an occupied space in response to a thermostat control signal. Incorporation of an airflow sensor allows the SDV to compensate instantly for any change in supply air pressure that might alter the supply volume resulting in a pressure independent variable air volume system.
