Intumescent Air Transfer Grille

These intumescent air transfer grilles are fire rated for both 30 and 60 minutes. These are designed for use in fire resisting doorsets and compartment walls. When dormant, the grilles enable air to be circulated throughout the building and in the event of a fire they are designed to close and restrict the flow of hot gases and fire.

• Up to 1 hour fire resistance
• The frames are constructed from Zintec mild steel
• The system is easy to install and maintenance free

Intumescent vents are for use on fire doors, not fire and smoke doors. If you require ventilation for a fire and smoke protection door you will need to install a smoke damper. Contact our customer service team today for more information.
