Medium Duty Backdraft Dampers
Series 7000

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.)

Series 7000 WT

Series 7000 WT Medium Duty, Maintenance-Free Weighted Backdraft Damper:

  • For installations where adjustable blade resistance is required to resist or delay opening.

  • Used to increase resistance to the opening of blades against airflow until a desired static pressure is achieved.

 
 
Series 7000 CW

Series 7000 CW Medium-Duty, Maintenance-Free Counterweighted Backdraft Damper:

  • Ideal for installations requiring a maintenance-free backdraft damper with field-adjustable pressure relief.

  • Used to accelerate opening of blades and designed to allow opening at lower pressures and airflow velocities.

 

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.)

 
Heavy Duty Backdraft Dampers
Series 7600

Series 7600 Heavy-Duty Backdraft Damper:

  • 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.

  • They are an excellent solution whenever resistance to vibration in fan isolation systems or resistance to the effects of turbulent air is necessary.

 

ET - Elevated Temperature Option:

  • 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.(See Options for more details.)

 

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.)

Series 8800
  • TAMCO Series 8800 Heavy-Duty Dampers are constructed with robust components to withstand up to 30” w.g. (7.5 kPa) of static pressure and velocities up to 5000 fpm (25.4 m/s).

  • They are designed for operation in temperatures ranging from -40°F (-40°C) to 300°F (149°C).

  • The innovative blade stop design increases free area. As a result, TAMCO Series 8800 pressure drop is significantly lower than that of industry standard heavy-duty dampers.

  • Series 8800 Dampers are constructed with all of the maintenance-free bearing and linkage components of other quality TAMCO products.

  • Assorted coatings and finishes can be applied to the Series 8800 Damper, further enhancing the range of applications for which this Series is suitable.
