Supplied Air Breathing masks [ Chemical Oxygen Technology ] Chemical Oxygen Technology [ Proven Technology - Optimised Function ] Self-contained MSA chemical oxygen [KO 2 ] breathingapparatus for use in oxygen deficient atmospheres, as
well as hazardous atmospheres containing smoke andtoxic gases offer protection for periods of between 15minutes and 4 hours for a variety of applications rang-ing from simple assistance and salvage to tough firefighting and rescue missions.The chemical oxygen apparatus applies the provenprinciple of regenerating the breathing air with oxygenproduced by the chemical Potassium Hyperoxide.Simultaneously retaining the carbon dioxide and
humidity contained in the exhaled air, these breathing
apparatus are very reliable and almost maintenance-
free for extended storage periods.The breathing apparatus AirElite 4h is designed for mis-sions of long duration, in particular for use in tunnels,
high-rise buildings and large storage facilities. In
underground mining it is used by the rescue teams for
quick rescue missions.
SSR 30/100, SavOx and SSR 90 are the standard oxygenself-rescuers that provide breathing safety for
evacuees from fire and smoke, and in gaseous / oxygen
deficient environments. They are used worldwide inmining and tunneling.In addition to these three models, the SavOx Cap 60offers a hood for additional protection of the eyes andface.The small breathing apparatus S15 and SAR 30 L arespecifically designed for use in situations requiring
immediate and reliable breathing protection if hazard-
ous atmospheres develop quickly and unexpectedly.Common to all MSA chemical oxygen apparatus is theircapacity to be stored for long periods in a condition of
immediate readiness, combined with minimum main-
tenance requirements. 30
