Low Leakage, Narrow Profile

Series 1400
Air-Foil Control Damper With 4" Blades

Series 1400 damper
  • Standard blade depth is 4” (101.6 mm).
  • When damper blades are in the fully open position, each blade seal extends only 0.2" (5.1 mm) beyond the 4” (101.6 mm) deep frame.
  • This damper's all-aluminum construction provides a prolonged and rust-free operational life.
  • Series 1400 dampers are assembled using slip-proof linkage components that keep blades aligned as per factory adjustment.
  • These dampers are supplied with extremely flexible silicone side seals and EPDM blade seals, that are resistant to weathering, compression set, and heat.
  • TAMCO seals provide outstanding dynamic fatigue resistance, ensuring consistent minimal leakage rate performance and sealing longevity.
  • TAMCO’s dual bearing system is self-sealing, self-lubricating, and non-absorbent, resulting in totally maintenance-free performance.

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

Series 1400 Air-Foil Control Damper With 4" Blades

  • Space-saving narrow profile is ideal for space restrictive installations.
  • Modulating, or 2 position control dampers.
  • Where maintenance is an issue.

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:

  • Excellent solution for high moisture/high humidity applications such as water treatment facilities, municipal pools, and greenhouses.(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.)

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 1400, and Series 1400 with ET, MR, or SW Options:

Leakage rate through a 36” x 36” (915 mm x 915 mm) damper does not exceed 2.35 cfm/ft² (11.9 l/s/m²) against 1 in w.g. (0.25 kPa) differential static pressure. Tested in accordance with ANSI/AMCA Standard 500 D.

ET - Elevated Temperature Option:

  • Blade and frame seals are extruded silicone, ensuring minimal change in leakage rates as temperature increases, making this damper ideal for high temperature applications.
  • Dampers are designed for operation in temperatures as high as 300°F (149°C) with bronze-oilite bearings.

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.
  • Blade and frame seals are extruded silicone, for reduced air leakage.
  • All zinc-plated, steel hardware is replaced wtih stainless steel, protecting hardware from rust and corrosion.
  • All aluminum linkage hardware parts are clear anodized.
