Air Supply Valves – Fire Rated

Fire-rated air supply valves provide fresh-air supply through ceilings and walls with built-in passive fire protection. Each valve is made from galvanised steel, powder-coated white, and incorporates an intumescent material that expands in the event of a fire to close the valve and help prevent fire spreading through the duct run. The valves carry a 1-hour fire rating.

Choose from four stocked sizes to match standard ducting: 100mm, 125mm, 150mm and 200mm. Installation is the same as a standard air valve, making them a straightforward specification wherever a protected supply point is required.

The extract-side equivalent is our fire-rated air extract valve, and standard air supply valves are available where fire protection is not needed. Order by 3pm for next-day delivery on stocked sizes.
