Profile Fan Series. Exhausts and supplies air to a wide range of commercial applications such as change rooms, laundries, warehouses and workshops, gymnasiums, bulk’ goods retail outlets and assembly halls. Cowl, base and inlet spigot are made of UV-stabilised plastic, steel components have a corrosion resistant finish.

Pressurisation systems prevent smoke from entering escape routes through air overpressure. In the event of a door opening or an air leak, the system reacts by increasing the air flow rate, so that the routes are always free of smoke in an emergency situation. Escape routes include corridors, staircases, lifts and lobbies.

Conclusion. The basic duct connection of a pressurization fan consists of a weatherproof external louvre, a plenum box, several duct reducers, two fire-rated canvas, pressurization and a non-return damper. The entire connection is then followed by the rest of

Pressurization of a shaft is one means of maintaining it tenable during a fire. This involves increasing the pressures inside the shaft above those of adjacent floor spaces by injecting outdoor air into the shaft with a supply fan. The direction of air flow would then

One of the main parts of a staircase pressurization system is a staircase pressurization fan (SPF). When a fire breaks out, these fans force clean air into the stairwell, preventing smoke from clogging the escape route. In high-rise buildings, the fans also help in pressurizing the stairwell. Stair pressurization fans are not turned on except

1/2 · Now if you open a stairwell door, the 4 square feet becomes 25 square feet. To achieve the same pressure, your initial 5,000 cfm now becomes about 36,000 cfm. If two doors are open, you’d need a 76,000 cfm fan. It needs to be accepted that the code mandated pressure cannot be met with egress doors open.
