Variable Air Volume (V.A.V) Control Dampers

Description• Chassis Material: Galvanized Steel Sheet. The pressure sensor is made of aluminum. • Usable of providing fresh air in a steady flow rate at ventilating systems. Able to be used for both supply and return air ducts. • Designed for applications that have high-velocity airflows or variable flow rates at a single duct. • On request, the chassis interior can be covered with heat and sound isolation. • Two models available: Prismatic model (VAV-151) and Circular model (VAV-251). • All VAV-units are equipped with an electronic velocity control device, a servo-motor and a pressure sensor. Requested pressure value is provided independently of resident constant or variable airflow rate.
