AF FIREGRILLE

AF FIREGRILLE is a fire protection grill for air exchange areas.

The product is made with an external structure in steel sheet.

Inside it has a series of wings made of an intumescent material, which at temperatures above 200 °C, it expands and closes the internal space preventing the passage of smoke and flames.

The internal space reduction is 30% for dimensions up to 300x300mm and up to 40% for dimensions bigger than 300x300 mm.
