Pressure Differential System

Product catalog summary

Overview
Pressure Differential Systems are vital for maintaining smoke-free escape routes in buildings. Systemair integrates safety with advanced ventilation technologies to enhance fire protection and evacuation efficiency.

Principle of Pressure Differential Systems
These systems facilitate safe evacuation and firefighting by combining EC motor technology with frequency converter control. This integration ensures efficient smoke extraction and overpressure, improving visibility and access during fires.

Functionality
The MUB-EC system by Systemair meets EN 12101-6 standards with fewer components, utilizing electronic control technology to eliminate pressure relief units, thus ensuring low energy consumption and high performance.

Benefits of Electronic Overpressure Systems

Facilitates faster evacuation through smoke-free stairways.
Enhances rescue operations with optimal air volume control.
Offers flexibility and security for emergency personnel.
Reduces construction and operating costs.
Allows architectural freedom without large air terminal devices.

Components
The system includes supply air fan units, control panels, and sensors, supporting real-time operational display and integration with smoke detectors and manual call points.

Multibox EC and Axial Fan AXC
These components maintain constant differential pressure in stairwells, adjusting fan speed to meet setpoint values and can be coupled with smoke extraction fans for enhanced performance.

Technical Specifications
Specifications for Multibox EC and Axial Fan AXC include power, airflow, temperature limits, and sound pressure levels, designed for efficiency, flexibility, and low noise.

Conclusion
Systemair's Pressure Differential Systems offer a comprehensive fire safety solution, combining advanced technology with practical design for effective smoke management and safe evacuation routes.

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 electronic...

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 the...

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 least...
