The BDR2 round backdraft damper was developed in response to industry requirements for a round backdraft damper. It features:
- Low leakage.
- Easy to install in round spiral ductwork.
- Specially designed blades with closing spring insuring a tight seal.
- Minimized back flow through the damper.
- Ruskin's exclusive blade hinge design with no frame penetrations to allow air leakage out of the duct.
- Integral rolled blade stop.
