Series 9000
Thermally Insulated Control Damper

Series 9000 Thermally Insulated Damper:

• If coil freeze-up is a concern.
• For air handler intake and exhaust.
• If the damper is closed approximately 50 % of the time.
• Where low leakage, maintenance-free dampers are required for ducted or non-ducted outside walls, or plenums.

SC - Severe Cold Temperature Option:

• Where retaining low leakage performance at severe cold temperatures is a concern. Silicone seals are virtually unaffected by cold winter temperatures. (See Options and Leakage for more details.)

MR - Moisture Resistance Option:

• Excellent cold climate solution for applications where dampers are exposed to extended periods of high humidity or high moisture, such as water treatment facilities, municipal pools, greenhouses and cooling towers.
• 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 and Leakage for more details.)

Recommendation: In applications where the humidity level is unusually elevated, or where there are extremely high levels of dust and dirt particles, TAMCO recommends that the damper linkage and bearing system should be cleaned once a year. This can be done by blowing away dust using compressed air. If needed, a domestic-strength steam cleaner can be used to loosen dirt, which can then be blown out with compressed air, along with any remaining water droplets.
