KAIR FIRE RATED SUPPLY CEILING VALVE 125MM

Fire rated ceiling valve usage is constantly growing in domestic and commercial properties. Protection against fire should always be a concern and all safety measures should be considered. These fire rated ceiling valves have a 60 minute rating, which prevents fire spreading through ceilings. In case of a fire the intumescent pad inside the ceiling valve expands and prevents fire spreading through a building.

The Kair fire rated exhaust valve incorporate integral intumescent materials. During a fire, the intumescent material expands and closes the apeture of the valve, re-instating the fire resistance of the structure.

Valve manufactured from 1.0mm thick sheet steel painted in white RAL9016 Satin. Mounting ring manufactured in 0.6mm thick galvanised steel with four 3mm fixing holes. The valve body is supplied with a cellular plastic gasket to form an air-tight seal.

The air flow is adjusted by rotating the control disc and locking with a lock nut when set. The control disc incorporates an intumescent pad which expands to seal the valve in a fire.
