FM27E / FM31E Electric Mobile Breathing-Air Systems 

The FM27E and FM31E have been specially designed to provide safe breathing-air supply for operatives working in hazardous environments. The 3 phase electrically powered road towable unit provides a breathing air supply of up to 2300LPM from either its 4 no. regulated CEJN342 profile outlets or 1 no. unregulated CEJN442 outlet. 
 
Based on the M27E and M31E Kaeser rotary screw compressors these units have been specially modified by Factair for breathing-air applications. The compressed air supplied is purified to breathing air standard by a 5-stage filtration and drying system that will provide breathing quality air well in excess of the criteria stated in EN:12021:2014, dry to a -40°C pressure dewpoint and provide active suppression of CO and CO2
In the event of a mains power failure, or failure of the primary compressor a visual/audible warning will be activated. An airline connection for an emergency breathing-air reserve is provided; should primary air supply pressure drop breathing- air will then continue to be delivered from this secondary source. 
 
There is also a mounting point for the Safeguard air quality monitor this unit will automatically monitor intake air quality and should readings exceed user defined limits the alarm will be activated. If the emergency breathing-air reserve is 
connected then air will be supplied from this source.
