The TENMAT Firefly Fire Rated Ceiling Air Valves are a unique and cost effective alternative to air valves with fire dampers.


The TENMAT Fire Rated Ceiling Air Valves are available in all sizes for both Extract & Supply. The Fire Rated Ceiling Air Valves offer a fire rated solution where recessed ceiling air valves are to be installed in fire rated ceilings.
