RVAV

rectangular variable air volume control dampers RVAV enable the regulation of supply or exhaust air volume in ventilation systems. They consist of a casing made of galvanized steel sheet, aluminium blades with silicone gasket, a measuring device and electric actuator. Depending on project requirements RVAV can be controlled over temperature sensors, air quality sensors or pressure sensors placed in a room or ventilation ducts. Data on differential measuring by a measuring device are transmitted to the motor actuator where they are compared with the reference signal. Depending on a signal difference, the actuator closes or opens therefore keeping optimal air amount in the room. On request, the regulators can be equipped with external insulation model RVAVZ.
