AF SYSTEMS AF M500J

The AF M500J pressurisation system is a device compliant with Ministerial Decree of 18 October 2019, designed to ensure the pressurisation of the smoke filter chamber in the event of a fire, following a command received from the fire detection system (or other signalling device).‎ In the event of an alarm, the control board will activate the pressurisation system, ensuring that an overpressure of 0.‎30 mbar (30 pascals) is achieved, taking into account pressure losses due to air leakage through fire-rated doors and windows (as per the average values tabulated in standard UNI EN 12101-13)* and any service penetrations sealed in accordance with the fire resistance characteristics of the smoke filter itself.‎ In the event of a power cut, thanks to the supplied backup battery kit, the AF M500J system will ensure that the positive pressure is maintained for over 120 minutes.‎ Further info from manufacturer on AF M500J AF SYSTEMS
