Low Leakage Aluminium Damper – AU350

It regulates the flow of air inside a duct, an air handler or other air handling equipment, and can be used to cut off air to an unused room or to regulate air in different parts of a building according to temperature, climate control, occupancy and so on. Operation can be manual or automatic: manual dampers are turned by a handle on the outside, while automatic dampers regulate airflow constantly through actuators controlled by a thermostat or building management system.
