Intumescent Fan Covers for windows, walls and ceilings

An intumescent fan cover for fan units mounted on walls, ceilings or windows, compatible for use over most leading fan models.

The fan cover fits around the fan unit and is fixed to the wall, ceiling or window. The unit is fronted with an MG or MGL Grille (Product 35), which is fitted with intumescent strips. In the event of a fire, the intumescent expands seals the opening, thus preventing fire and smoke spread.

  • Intumescent fan covers can offer up to 1-hour intumescent fire protection. Effectively provides fire and smoke protection, ideal for use in escape corridors and also staircase fire escapes.
  • Suitable for use on numerous surfaces, including brickwork, blockwork, plasterboard, etc. For plasterboard, or lath-and-plaster walls, use metal or timber fixings prior to installing the fan cover.

We can supply fan covers with smoke shutters activated by a 24V electromagnet with an auto-reset solenoid.
