Fresh Air Injection Dampers FLIK

This damper design replaces the function of jet fans within road tunnels. Depending on the blade’s position, the fresh air is supplied into the selected tunnel area or smoke / Co2 is exhausted to outside. The design enables high flow velocities within the blade’s gap, which leads to an ideal efficiency at smallest damper surface.

  • Swivel angle of blades: up to 150°
  • Pressure-resistant: up to 6.000Pa
  • Flow velocity: up to 50m/s
  • Leakage rate: 0,1m³/m²/s at 4.000Pa
  • Material: galvanized steel and stainless steel
  • Dimensions: up to 5x5m
