PD-1250 Pressure Relief Backdraft Damper
Formed aluminum blade and aluminum frame damper
The PD-1250 damper provides backdraft protection in light to medium duty applications that demand less than 12 cfm per square foot of leakage at 1/2 inch WG. The PD-1250 provides system relief when operational pressures exceed system defined maximum level.
- Aluminum construction maintains a good-looking appearance.
- Blades overlap frame, providing optimum resistance to weather.
- Non-metallic blade-to-blade seal provides quiet operation during highest spot velocities.
