Backdraft dampers are used in ventilation systems to allow airflow in one direction and prevent airflow in the opposite direction. A pressure relief damper is developed with an elevated and adjustable start-open pressure while providing the backdraft function. Backdraft dampers are operated by gravity (where pressure or velocity opens and closes the damper). Overlapping blades provides less leakage. |
