The air flow contributed by the pressurisation system can eliminate that smoke from the staircase. It is assumed that during the evacuation, the occupants will remain alert and ready, and be familiar with the area in which they are moving, with the ensuing reduction of the time they remain inside the building. CLASS A SYSTEM

In a high-rise building it is possible to increase the pressure of a stairwell to prevent the infiltration of smoke if fire crews configure the fans

Additionally, the blade pitch is field adjustable to accommodate system changes. Capacity Ranges:

However, just because the building meets the definition of a high-rise does not necessarily imply that every stairwell, or any stairwell for that matter, is required to be provided with stairwell pressurization. The code simply requires that every exit stair serving floors more than 75 feet above the lowest level of fire department access shall

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.
