The Siberkit fire has been designed to automatically control the differential pressure and maintain it at 50Pa in a single stage in accordance with the UNE-EN 12101-6 standard. The Siberkit fire pressurization kit consists of a control panel and a drive unit (any unit for air supply) that will provide sufficient pressure to the stairways or escape route. The Siberkit fire has everything needed to operate autonomously, making the installer's job much easier, and it will only need to be connected to the ventilation unit and the fire detection center.
