Aluminum Gravity Backdraft Damper: 2BDE/2BDF
The 2BD dampers offer backdraft protection in light to medium duty applications that demand less than 12 CFM per square foot of leakage at 1/2" w.g. Non-metallic blade-to-blade seal provides quiet operation during the highest spot velocities.
The damper's good looking appearance is maintained by sturdy, corrosion-resistant aluminum construction. Contemporary styling features blades that overlap the frame for optimum resistance to weather.
- 2" deep back draft damper constructed of .090 frame and .025-.050 blade thickness.
- General operations based on gravity, air flow and pressure.
