Fire resistant ventilation grid - type W66 


Type W66

Function

  • At room teperature: The ventilation between 2 rooms will be ensured as per normal conditions.
  • Under fire conditions: The ventilation will be interrupted and the fire resisting function will come into effect.

Working Principle

  • The closing of the ventilation opening is realized by the louvres that expand/swell so much that the ventilation is closed off above temperatures of ±120șC.
  • This will act as a static fire resistant closure for 60 Minutes

Mounting

  • The grid is simply mounted in the opening that should be ventilated.
  • The gap between the grid and the wall is then filled with a fire resistant putty/foam or silicone.
  • A Test Certificate is available on request.
