Intumescent Grille / Fire Damper 150x150mm

Firepro FG40 Intumescent Fire Grills

The Firepro FG40 Fire Grills are designed to protect apertures in fire-rated walls and floors. Under normal conditions, they provide free-flowing ventilation, but in the event of a fire, the intumescent material rapidly expands, sealing the opening to maintain complete fire integrity.

These grills are attractive, simple to install, and cost-effective, making them ideal for residential, commercial, and industrial HVAC applications where fire-rated ventilation is required.

Construction

• Made from rigid PVC extrusions with a hollow cross-section

• Hollow section filled with intumescent material

• Robust and easy to clean

• No moving parts, requiring minimal maintenance

Operation

• Under fire conditions, the intumescent core expands rapidly

• PVC casing softens to allow unrestrained expansion

• Core expands to many times its original thickness, forming a firm, non-combustible fire seal

• Low activation temperature and rapid response time ensure effective protection

Applications

• Ventilation through fire-rated walls and floors

• Airflow through metal duct penetrations in floors and walls

• Fire-protected HVAC air distribution points
