The company's MRC 2 has been designed with the chamber´s user environment in mind, said Jama.
Air purification technology has been added that renews oxygen - exhaled air is captured via a "scrubber", a cassette that chemically binds the carbon dioxide.
To lower the temperature in the rescue chamber, it is showered on the outside. Air from a tube maintains an overpressure that prevents pollutants such as dust, smoke or gases from penetrating.
If the power supply is interrupted, a reliable and well-sized battery pack is activated that lasts up to 50 hours. The chamber is also equipped with a toilet, emergency exit and visual signals such as external sound and light alarms.
"The [air quality features] mean that the need for fresh air masks has been eliminated, you can simply sit and breathe as usual. Avoiding using a mask is a great convenience and significantly reduces stress," said Johan Marklund, Product Manager R&D at Jama.
