BDR2 Commercial Backdraft Damper

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
