Stairways Pressure Differential Systems

The system solution in stairways

In case of fire, smoke gases are a dangerous threat to escaping people and can also endanger and obstruct rescuers. Therefore, electronically controlled positive pressure units are the next step in fire protection.

The fire fighters can use an ordinary switch to increase the supply air fan volume to maximum air volume and therefore less mobile fans are necessary or even none at all. Electronic pressure differential systems are a great help for self rescue. They also give an additional protection from smoke gases for the fire fighters during high fire temperatures, provide a clear view and allow a faster approach to the source of fire.

Benefits of electronic overpressure systems

  1. Faster self rescue: Fire escape stairways are recommended even if other arrangements are permitted for escape and rescue routes. People evacuation is faster through smoke-free stairways or stairways with less smoke – the panic risk can be reduced.
  2. Faster rescue by others: On electronic overpressure systems, the air supply of the fans can be switched to the maximum air volume by a fire fighter's switch. This enables pushing back and leading smoke away, even at high fire temperatures. The pressure in the stairway exceeds the standards limitation, and a time-consuming installation of mobile fans, allowing a clear view, in many cases is unnecessary.
  3. Reduction of construction costs: Openings for air outlets are not required. Control dampers and additional weather protection equipment are usually not necessary.
