Transit Dampers

AWV manufactures top-quality dampers to meet and exceed transit applications such as large scale projects, i.e. road tunnels, rail tunnels, and underground metro stations. Tunnel fire dampers are designed to be used as life saving equipment to ensure that the extractions of smoke and toxic fumes during a fire are efficiently maintained during the evacuation of passengers. These dampers also provide a protective barrier to keep fire away from other capital investments such as ventilating fans and silencers.
