Series 7000 CW Suggested Specification (36 KB)
Ideal for installations requiring a robust back draft damper for adjustable pressure relief.
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.
Counterweights are fully adjustable and can be set to relieve air pressure differentials less than .01" w.g.
Counterweights are threaded and allow adjustments to be made with only one tool.
Brackets are slotted to allow precision slide adjustment of the weights.
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 counterweighted 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 counterweighted back draft dampers are available in Front Flange, In Duct, or Rear Flange mounting types.
Series 7000 Counterweighted Back Draft Dampers allow mounting for horizontal air flow and both air flow up and down operation.
