Low Leakage, Maintenance-Free, Dependable

Series 7000
Medium-Duty Backdraft Damper

Series 7000 Backdraft Damper
  • TAMCO's aluminum construction provides a long, rust-free operational life.
  • Aluminum pivot points are over-sized for additional strength and durability.
  • TAMCO's backdraft damper blades are securely linked via a large diameter aluminum linkage rod.
  • Self-lubricating Celcon bearings ensure a maintenance-free and long-cycle life.
  • Silicone seals are provided as standard to ensure sealing longevity and remain flexible down to -40° F/C.
  • TAMCO’s linkage and bearing systems combine to provide durable, maintenance-free performance.
  • TAMCO Backdraft Dampers are available in Front Flange, In Duct, or Rear Flange install types
  • Series 7000 Backdraft Dampers allow mounting for horizontal airflow and airflow up operation.

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.

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. (See Options for more details.)

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.(See Options for more details.)

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:

  • All zinc-plated steel hardware is replaced with stainless steel, protecting hardware from rust and corrosion when exposed to high humidity or high moisture environments.

SW - Salt Water Resistance Option:

  • Extruded aluminum frames, blades and hardware are clear anodized to a depth of 0.7 mil. (18 microns). This prevents rusting and pitting when backdraft dampers are exposed to salt spray or high humidity environments.
  • All zinc-plated, steel hardware is replaced wtih stainless steel, protecting hardware from rust and corrosion.
  • All aluminum linkage hardware parts are clear anodized.
