Face & Bypass Damper

Series 1000 FB

  • These dampers are built with uninterrupted linkage. As a result, there is no mechanism that will loosen, fail, or be omitted.
  • The transmission of torque, or stroke, is direct and without losses,
  • Section connections will not develop any wear or play.
  • The specifically designed blade extrusion is unique to this product.
  • This product offers a choice of opposed or parallel blade action.(Blade action type must be the same for the Face and the Bypass sections of any unit.)
  • Face & bypass dampers are constructed with all of the maintenance-free bearing and linkage components used in Tamco’s other high-quality products.

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

Series 1000 FB, 1500 FB, 9000 FB Face & Bypass Damper:

Although Tamco manufactures these Series for use in face and bypass applications, we suggest that two separate dampers, each operated with its own dedicated actuator, would be the optimal method of achieving face and bypass operation.

Series 1000 FB and Series 1000 FB with ET, MR or SW Options:

The leakage rate does not exceed 3 cfm/ft² (15.2 l/s/m²) against 1 in w.g. (.25 kPa) differential static pressure.

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

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

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 highway

Please click the option above that is most applicable to you for more information.

Recommendation: In applications where the humidity level is unusually elevated, or where there are extremely high levels of dust and dirt particles, we recommend that the damper linkage and bearing system should be cleaned once a year. This can be done with the use of a domestic strength steam cleaner. The loosened dirt and water droplets can then be blown out with compressed air.

SP – Standard profile

  • Manufactured with 4” (101.6 mm) deep frames
  • Manufactured with blades that are a maximum 6” (152.4 mm) deep.

NP – Narrow Profile

  • Manufactured with 4” (101.6 mm) deep frames
  • Manufactured with blades that are a maximum of 4” (101.6 mm) deep.
  • Space saving narrow profile is ideal for space restrictive installations.
