Backdraft Damper: 2BDHD
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.
- Blades that overlap the frame for optimum resistance to weather.
- 2" heavy duty back draft damper constructed of .125 frame and .070 blade thickness
- General operations based on gravity, air flow and pressure
