Model BD-330 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, delivering dependable, power-free backdraft protection. With a non-flanged design for flexible field installation, the BD-330 is commonly specified as an accessory for wall-mounted fans and centrifugal inline fans.
