Backdraft Damper

Series 7600 CW: Internally Counterweighted Heavy-Duty

Each blade is fitted with a fixed internal counterweight.
Counterweights are provided to accelerate opening of blades, and to allow blades to achieve the full open position at lower pressures and airflow velocities.
Tamco heavy-duty backdraft dampers are constructed with robust components to withstand up to 12” w.g. (3.0 kPa) of static pressure and velocities up to 3500 fpm (17.8 m/s).
Blades are designed with a rounded head. This reduces pressure loss.
Tamco’s dual bearing linkage system is self-sealing, self-lubricating, and non-absorbent, resulting in a maintenance-free performance.
Silicone seals are provided as standard to ensure sealing longevity and remain flexible down to -40° F/C.
For horizontal and vertical airflow operation

Caution: Never use any lubricants, such as grease or silicone, on Tamco dampers.

Used to accelerate opening of blades and designed to allow opening at lower pressures and airflow velocities
Specifically designed for installations requiring a heavy-duty backdraft damper, subjected to elevated velocities and operating pressures
Recommended for use in high-pressure isolation systems, air handling units, gen sets, and fan inlet or fan outlet locations

Suitable for high heat environments where temperatures may reach as high as 300°F (149°C),and where UL regulated control dampers are not a requirement
For use in back-up generator stations, where excessive heat may be an issue
For test laboratory applications, wherever high-heat conditions may exist
A practical solution in mildly acidic applications, where Celcon bearings may not withstand environmental conditions

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

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
