A stairwell pressurization system is considered a smoke control system and is subject to the many requirements of Chapter 909 in the building code. Taking advantage of the stairwell pressurization alternative will require that a rational analysis be prepared by a qualified design professional.

In case of fire in a high rise building, a Stair Pressurization Fan (SPF) uses clean outside air to pressurize the air in stairwells. The pressurized air helps people escape the fire and firefighters battle the fire. Stairways are Fire Escape Routes Nowadays, stairwells have better fire ratings than the rest of the building.

This allows stairwells to remain mostly free from smoke. A pressure control unit is installed in combination with a roof light dome, e.g. at the top of a stairwell. When a smoke detector detects a fire in the building, the dome opens and the fan is activated. The pressure control unit creates a minimum closed-door pressure of 15 Pa.

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

realise a constant differential pressure in stairwells, using EC fans. The constantly-measured differential pressure is evaluated in the control system in real-time and compared with corresponding setpoint values. The speed of the EC fans is adjusted by the control system so that the setpoint values are adhered to in the stairwell.

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

5/27 · In its simplest form, a stair pressurization system uses a supply fan to blow outside air into a stairwell, creating a positive pressure differential across the enclosure boundary. However, the design of these systems can depend greatly on the codes and standards used in design. Per IBC Section 909.20.5, the differential pressure limitation
