Series 7000 Medium-Duty, Maintenance-Free Backdraft Damper:

  • Ideal for installations requiring a maintenance-free backdraft damper, subjected to medium airflows and operating pressures
  • Suitable wherever low-leakage performance is essential

Standard air leakage data for Series 7000 Backdraft Dampers is certified under the AMCA Certified Ratings Program.

Air leakage through a 24″ x 24″ (610 mm x 610 mm) backdraft damper does not exceed 4.32 cfm/ft² (21.95 l/s/m²) against 1″ (0.25 kPa) w.g. differential static pressure at standard air.

MR – Moisture Resistance Option:

  • Suitable for applications where dampers are exposed to extended periods of high humidity or high moisture, such as water treatment facilities, municipal pools, and greenhouses.
  • Cost effective alternative to the Salt Water Resistance Option for applications where salt spray is not a concern

SW – Salt Water Resistance Option:

  • Ideally suited for coastal climates
  • Recommended for inland applications, where tire spray from winter-salted roads have been known to corrode dampers installed in close proximity to roads or highways
