Functional description

When a fire is detected, two or three dampers near the fire site open automatically; the other dampers remain usually closed. At the same time, the exhaust fans are run at maximum speed to ensure efficient smoke exhaust. This enables people to leave the danger zone, and firefighters to fight the fire.

Nominal sizes400 × 440 – 2200 × 2175 mm
Volume flow rate range350 – 95,700 l/s or 1260 – 344,20 m³/h
Differential pressure rangeUp to 5000 Pa
Operating temperature0 – 400 °C/120 mins
Leakage rate0.1 m³/s per m² at 3000 Pa


TROX tunnel dampers are specially designed safety components to control the volume flow rate of the extract air from tunnels; they meet the RABT and RVS requirements.

Units consist basically of a casing, movable blades and linkage. Sprung steel side seals allow for the longitudinal expansion of the components at temperatures up to 400 °C for 120 minutes and ensure very low leakage rates even at high pressures.

Special characteristics

  • Excellent low leakage performance of 0.1 m³/s per m² at a differential pressure of 3000 Pa
  • For high operating pressure of up to 5000 Pa
  • Low pressure drop
  • Maximum corrosion and temperature resistance
