Casualty bags made of rubberised fabric as well as gastight have high ambient temperature inside the bag rise up within a short time to 60 70C and the humidity to 90 100%.

However, owning to the gas-proof design of this protective-system, the time it can be worn may be restricted to a few minutes depending on the ambient temperature.

With the protective NBC-ventilation equipment the wearing time at high ambient temperature increase up to 4 hours two time a day with a rest of 2 hours.

Through the air distribution system of the casualty bag with the protective ventilation unit  SBV-93, filtered air is blown into the interior of the bag.

In connection with the air-distribution system installed in the bag, its interior is not only evenly cooled to a bearable temperature; the moist air simultaneously abducted via discharged valves, thereby creating an acceptable environment.

This protective device was developed and tested close with and delivered to the Austrian Federal army and is now in service in 24 armies in Europe, Near and Far East and South America.
