CVAV

circular variable air volume control dampers CVAV enable the regulation of supply or exhaust air volume in ventilation systems. They consist of an adapted air-tigth damper, a measuring device and an electric actuator. The actuator turns a damper blade which has a rubber seal on it. Depending on project requirements CVAV can be controlled by 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 CVAVZ.
