About Wall Mounted Fan Covers
Intumescent fan cover units can be installed over Vent-Axia, Xpelair or other makes of wall or window fans, providing fire and smoke protection to escape corridors and staircase fire escapes. Available in brown or white. Other colours and sizes can be made to order.
Application Instructions
The wall-mounted unit simply fits over the fan unit, offering one hour fire protection. This can be fixed to brick, block or concrete using raw plugs & steel screws (32mm No8 or No10 screws or small rawl bolts).
For plasterboard or lath & plaster walls before the plasterboard is applied metal or timber fixings can be allowed for while building, otherwise if fixing to existing walls or ceilings use steel butterfly toggle bolts.
