The Ø125mm fire rated metal extract valve has been developed to provide maximum protection for penetrations created by air valves fitted in fire rated ceilings.
The extract valves are available in two colours - RAL 9010 (Pure white) and RAL 9016 (Traffic white).
The extract valve does not require any additional supports or fixing and can be fitted as normal. The unique intumescent gasket material does not restrict the air flow of the air valve. However, in a fire situation, the material rapidly expands to seal off the open air valve. The penetration is then sealed against the spread of fire and the fire rating of the ceiling construction is maintained.
The fire rated metal extract valve has been tested for fire resistance in accordance with BS EN 1365-2:1999 and BS 476 standards.
