BD-300 : Backdraft Damper, Vertical Mount
Model BD-300 is a vertical-mount backdraft damper designed for horizontal airflow applications, preventing reverse airflow when the fan is off. The blades open in response to system pressure differential and close by gravity for reliable, power-free backdraft protection. A flanged intake simplifies installation and secure mounting. Commonly specified as an accessory for wall-mounted fans and centrifugal inline fans.
