staircase pressurization fan catalogue

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

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.

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.

The stairwell pressurization system is a mechanical ventilation system. In order to pressurize the stairs of vertical buildings, it is necessary to install sets of fans that suck air into the

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.

11/14 · The most common way for designers to comply with these requirements is a stairwell pressurization system. The premise of stairwell pressurization is pretty simple: push a bunch of outdoor air in with a fan to keep the smoke out. This allows for building occupants to evacuate the building safely. From an Architectural standpoint, there are some

Stairwell pressurisation and purging systems. When a smoke detector detects a fire in the building, the dome opens and the fan is activated.

A pressurization grille will be installed at every 3-4 floors in the staircase. However, a pressurization grille is needed for each lift lobby because lift lobbies are not interconnected. In

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
