The overpressure ventilation technology was invented during the eighties as an appropriate element within fire protection concepts for skyscrapers. The manufacturer Systemair was instrumental in pushing the development of an important improvement: the electronic control for pressurisation ventilation fans. This system provides higher security for selfrescue and especially for the fire brigade.

Principle Pressure Differential Systems Stairways Pressure Differential Systems Important for save live and for a fast fire fighting In the case of fire, it is not just for the people fleeing that smoke gases present the greatest threat. It also puts the rescue service personnel at risk and hinders their work. Therefore, electronically-controlled overpressure systems bring a new dimension to fire protection. With a simple switch, the fire services can switch the supply air fans to maximum power, limiting the need for mobile fans to be used, or even making them unnecessary. This means that...

Principle Pressure Differential Systems Ten 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 firefighter‘s switch. This enables pushing back and leading smoke away, even at high fire temperatures. The pressure in...

Multibox EC Thanks to a special control system, we are able to 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. This prevents the forces required to open the doors from getting too high (max. 100 N). By selectively controlling the outflows in the individual storeys, e.g. windows, the necessary airspeed (at...

Axial fan with frequency control Thanks to a special control system, a constant differential pressure is realised in the stairwell using AXC 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 fans is adjusted by the control system so that the setpoint values are adhered to in the stairwell. This prevents the forces required to open the doors from getting too high (max. 100 N). By selectively controlling the outflows in the individual storeys, e.g. windows, the necessary...
