Founded with smart business administration and workmanship, we at "KRISHNA ENGINEERING" are occupied as manufacturer and supplier of Lobbies Pressurization System in Pune, Maharashtra, India. A smoke shaft is a common method for ventilating lobbies of tall buildings, used to maintain tenable conditions in the common escape routes in the event of a fire in the building. Originally smoke shafts were developed by BRE as a passive system requiring large risers and dampers to allow for the buoyancy effects of the fire to provide motion to clear smoke from the corridors. The FlÃ¤kt Woods Smoke Shaft Vent reduces the required shaft area specified by BRE by the addition of a set of smoke extract fans located at roof level; saving on lettable space within the development and removing the risk of wind or negative heat effects limiting the effectiveness of the passive ventilation system.
