Description

The backdraft damper is an automatic mechanism designed to connect 2 air ducts when building ventilation systems. The damper is fitted with metal flaps that open when there is airflow in one direction and close when air is drawn back. When there is no airflow, the flaps remain closed with the help of a spring.

 

  • Designed to connect 2 separate air ducts
  • Prevents treated air from flowing back into the room
