MSA Safety has more than 100 years of experience, reliability and competence in the field of breathing apparatus and Personal Protective Equipment. This has paid off and made it possible for MSA to develop the AirElite 4h. MSA has successfully applied the principles of oxygen generation from potassium hyperoxide (KO2) for breathing air regeneration for more than 40 years now.

The AirElite 4h is the state of the art successor to the AirElite 2h, which was developed in the year 1995. This was the first long duration device using the KO2 technology exclusively in the market.

Together with its integrated control monitor the IC-Air it forms a unique closed-circuit breathing apparatus.

All the benefits of the KO2 principle are now available for a long service periods of up to four hours.

Developed for all practical purpose in cooperation with the accreditation testing body DEKRA EXAM Ltd. and customers all over the world, the unanimous needs of fire brigades and mine rescue teams were analyzed and taken into consideration. Its main applications is by far for fire brigades at tunnels, chemical plants (like refineries), large storage facilities and high-rise buildings.

Exclusively for mine rescue teams we offer the well-established KO2 technology for their long duration underground and rescue missions.
