Ideal for installations requiring a robust back draft damper, subjected to higher
air-flows and operating pressures.
Air leakage through a 24" x 24" (610mm x 610mm) back draft 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.
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.
