Ultra-Low Leakage Air-Foil Control

Series 1500
Ultra-Low Leakage, Enhanced Air-Foil Control Damper

Series 1500 damper
  • The Series 1500 damper utilizes smooth aluminum end caps installed on the hollow air-foil blades.
  • This improves sealing where damper blades meet the side frames and reduces leakage rates significantly.
  • The unbroken surface of the end caps creates nearly frictionless wear on the frame seals. This enhances damper longevity and ensures that the damper retains consistent sealing ability over time.
  • Silicone seals are provided as standard to ensure tight sealing in both cold or warm climates.
  • Series 1500 ultra-low leakage dampers are 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.)

Series 1500 Ultra-Low Leakage, Enhanced Air-Foil Control Damper:

  • When the damper is closed and a low air leakage rate is critical.
  • Where infiltration is a concern.
  • Where condensation and freeze up are not a concern, but where an energy efficient, low infiltration, maintenance-free damper is essential.
  • Ideal specification choice for outside wall dampers intended for use in warmer climates, where energy efficient, non-insulated dampers are required.

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 1500 Ultra-Low Leakage, Enhanced Air-Foil Control Dampers, including all applicable options, are rated Leakage Class 1A at 1” w.g. static pressure differential. Standard air leakage data is certified under the AMCA Certified Ratings Program.

ET - Elevated Temperature Option:

  • 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.
  • All zinc-plated, steel hardware is replaced wtih stainless steel, protecting hardware from rust and corrosion.
  • All aluminum linkage hardware parts are clear anodized.
