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.

The fans are used: as a part of a smoke extraction system for air pressurization to create a positive air pressure differential in stairway enclosures,

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

BMS "How a Staircase and Lift Lobby Pressurization System works in the event of Fire."

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.

With the Systemair Pressure Differential System those fans are not needed. Higher security for emergency task forces: High air velocities combined with electronically controlled ventilation reduces the concentration of flammable gases and hot air in the zone on fire. This reduces the risk of backdrafts and delays flashover.

In order to pressurize the stairs of vertical buildings, it is necessary to install sets of fans that suck air into the stairwell, keeping pressure of 0.10 – 

Stair pressurization fans are not turned on except when there’s smoke and usually, when the fire alarm detects smoke, the fans will be turned on automatically. You won’t have to worry about any details when you call us for your staircase pressurization services.
