Applications:

• 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.
• If coil freeze-up is a concern.
• For air handler intake and exhaust.
• If the damper is closed approximately 50 % of the time.
• Caution: 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 easily with the use of a domestic strength steam cleaner. The loosened dirt and water droplets can then be blown out with compressed air.
  

   Air leakage:

• Leakage does not exceed 3 cfm/ft.² against 1” w.g. differential static pressure.

• These salt water resistance dampers maintain all of the features of the 9000 SC damper, which control the forces of radiation, convection, and infiltration. This ensures blade insulating effectiveness.
• Type 316 stainless steel replaces all parts that are zinc-plated, steel hardware of SERIES 9000 SC dampers.
• All aluminum parts are anodized to a depth of 0.7 mil. (18 microns).
• Side seals and blade gaskets are made of silicone.
• This grade of silicone is virtually unaffected by cold winter temperatures,down to -40°F (-40°C).
• Ensures minimal change in leakage rates as temperature drops, making this damper ideal for severe cold weather applications.
• Constructed with all of the maintenance-free bearing and linkage components of other quality TAMCO products.
  (Caution: Never use any lubricants, such as grease or silicone on TAMCO dampers.)
