Maintenance-Free Air-Foil Control

Series 8800
Heavy-Duty Air-Foil Control Damper

Series 8800 damper
  • 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.

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

Series 8800 Heavy Duty Air-Foil Control Damper:

  • Specifically designed for elevated static pressure and velocity applications.
  • Recommended for use in high-pressure isolation systems, air handling units, gen sets, and fan inlet or fan outlet locations.
  • Effective solution wherever heavy-duty balancing is required, or for high pressure and/or velocity mixing applications.
  • Ideal for use in facilities such as power plants, mining operations, water treatment plants, military complexes, sports complexes, laboratories, pharmaceutical processing plants, bottling and brewery plants recycling plants, and refineries.

MR - Moisture Resistance Option:

  • Cost effective alternative to the Salt Water Resistance Option for applications where salt spray is not a concern.
  • Suitable 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. (See Options for more details.)

SW - Salt Water Resistance Option:

  • Designed to be used in any of the applications listed above, where there is salt spray or salt content in the air and/or where moisture levels are elevated.
  • 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.)

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.

Series 8800, and Series 8800 with MR or SW Options:

Air leakage through a 24" x 24" (610 mm x 610 mm) damper does not exceed 3.9 cfm/ft² (19.8 l/s/m²) against 1 in w.g. (0.25 kPa) differential static pressure.

MR - Moisture Resistance Option:

  • All zinc-plated steel hardware is replaced with stainless steel, protecting hardware from rust and corrosion when exposed to high humidity or high moisture environments.

SW - Salt Water Resistance Option:

  • Extruded aluminum frames, blades and hardware are clear anodized to a depth of 0.7 mil. (18 microns). This prevents rusting and pitting when dampers are exposed to salt spray or high humidity environments.
  • All zinc-plated, steel hardware is replaced wtih stainless steel, protecting hardware from rust and corrosion.
  • All aluminum linkage hardware parts are clear anodized.
