Smoke Pressurization Fan at Katrina Addie blog

Smoke Pressurization Fan. The pressurization is used to push back on smoke, keeping the smoke out. Where one fan is used, it is generally placed at the top of the stairwell or at the bottom. Smoke exhaust fans are ul793 listed for operation at 500 f (260 c) for 4 hr or 1,000 f (538 c) for 1 hr. During normal mode, these fans are running at low speed to provide basic ventilation to staircases and lift lobbies. A good pressurization system uses variable speed fans. For systems using multiple fans, these fans may be placed along an exterior wall (if one of the stairwell walls is an exterior wall of the building). When there's a fire, clean outside air is forced by a stair pressurization fan into a stairwell. Stair pressurization is the concept of pressurizing an enclosed stairway to have a higher pressure relative to the rest of the building, reducing the chance that smoke and other fire products. During fire mode, pressurization fans ramp up their rotational speed to pressurize the staircase and lift lobby. Pressurisation fans provide an elevated pressure with the protected regions, preventing smoke leakage into the lobby / stair well by overcoming the pressure developed by a burning fire. Eurotec have developed the lift shaft & stairwell pressurisation controller, which enables control of the pressurisation fan in your stair well or lift. The pressurization may be done with one or more fans.
