TM 75EI system – ventilation grids

The double-sided ventilation grilles with clearance are designed for fire doors with a fire resistance of 30 or 60 minutes.

They have a thermo-expandable composite filling that swells as low as 120º, creating a sealed, non-combustible barrier. At the same time, they provide adequate ventilation of rooms and protection against fire and smoke.

Grilles are available in various sizes and flows. They are used in public buildings.

Advantages of the system

  • two-sided ventilation grids with clearance are dedicated to use in fire
    protection doors with fire resistance 30 or 60 minutes
  • filled with thermally expanding composite, swelling in 120 degrees creating
    tight and non-flammable barrier,
  • they also provide good ventilation of rooms and protection against fire and
    smoke,
  • grids are available in various dimensions and with various flow rates,
  • they may be used in public utility buildings.
