Auto Damper

Auto dampers also known as stack heads or roof ventilators are used when exhausting through the roof. The auto damper is placed on top of the ductwork and prevents rain from entering the ductwork. Internal flaps automatically open when airflow is present and close when airflow has stopped. Constructed from galvanized steel for superior corrosion resistance. The heavy duty mounting flange provides a secure connection to the mating ductwork. Ideal for venting paint booths, powder coat booths, mixing rooms, and other industrial equipment.
