Series 7000
Medium Duty, Maintenance-Free Back Draft Damper


  • Ideal for installations requiring a robust back draft damper, subjected to higher air-flows and operating pressures.

   Air leakage:

  • Air leakage through a 24" x 24" (610mm x 610mm) back draft damper does not exceed 4.32 cfm/ft (21.95 l/s/m) against 1" (0.25 kPa) w.g. differential static pressure at standard air. Standard air leakage data is certified under the AMCA Certified Ratings Program.
  • TAMCO's aluminum construction provides a long, rust-free operational life.
  • Aluminum pivot points are over-sized for additional strength and durability.
  • 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 back draft damper blades are securely linked via a large diameter aluminum linkage rod.
  • TAMCO’s linkage and bearing systems combine to provide durable, maintenance-free performance.
  • TAMCO's back draft dampers are available in Front Flange, In Duct, or Rear Flange mounting types.
  • Series 7000 Back Draft Dampers allow mounting for horizontal air flow and air flow up operation.
