Show more BACKDRAFT SHUTTER DAMPER - Square Style design air duct connector with the back draft damper, adopts durable environmentally friendly materials, acid and alkali resistant, oil resistant, heat resistant. backdraft damper is able to allow contaminated air to flow out of the home but prevents contaminated air from sweeping back in to the home. Without a backdraft damper in place, horrid odors that sometime infiltrate a certain room in the home would not have a way of dissipating WORKING PRINCIPLE - 1. When exhaust started, the air pressure will push and open the butterfly valves, and the odor and exhaust gas is quickly discharged into the public flue. 2. When exhaust is ended, the duct butterfly valves will automatically closed under the principle of gravity. The check valve will remains closed always to to prevent exhaust gas, debris, dust, and odors of the public flue from entering to the room VALVE OPEN & CLOSE AUTOMATICALLY - HVAC butterfly valve with rear spring and 17°acute angle tilt design, helps to open the valve smoothly when it was driven by airflow during exhaust process.
