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.

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.

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

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

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.
