Airfoil Control Damper

Series 1500: Ultra Low Leakage

  • All-aluminum construction provides a prolonged and rust-free operational life.
  • Tamco’s dual bearing linkage system is self-sealing, self-lubricating, and non-absorbent, resulting in a maintenance-free performance.
  • Smooth aluminum end caps are installed on the hollow air-foil blades.
  • Improved sealing where damper blades meet the side frames which reduces leakage rates significantly.
  • End caps create nearly frictionless wear on the frame seals. This enhances damper longevity and ensures that the damper retains consistent sealing ability over time.
  • Tamco silicone seals provide outstanding dynamic fatigue resistance, ensuring consistent minimal leakage rate performance and sealing longevity.

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

Series 1500 Ultra-Low Leakage, Enhanced Airfoil Control Damper:

  • When a low air leakage rate is critical
  • Where an energy efficient, low infiltration, maintenance-free damper is essential
  • For outside walls in warmer climates
  • Standard blade depth is 6″ (152 mm).

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.

Options are available for the airfoil control damper (Series 1500) which can be upgraded to the following options to suit a wider range of applications:

ET – Elevated Temperature Option:

  • Blade and frame seals are upgraded to extruded silicone.
  • For operation in temperatures as high as 300°F (149°C)
  • Bronze-oilite bearings replace Celcon and polycarbonate bearings.

MR – Moisture Resistance Option:

  • Stainless steel hardware replaces zinc-plated components.

SW – Salt Water Resistance Option:

  • Extruded aluminum frames, blades and hardware are clear anodized to a depth of 0.7 mil. (18 microns).
  • Blade and frame seals are extruded silicone.
  • All zinc-plated, steel hardware is replaced with stainless steel, protecting hardware from rust and corrosion.
