Circuit:

Exhalation

Inhalation

The exhalation air is enriched with oxygen

CO2 and H2O are absorbed

KO2 - function and reaction:

2KO2 + CO2 + H2O >> [K2CO3*H2O] + 1.5 O2 + E(Potassium Hyperoxide) (Potassium Carbonate) (Heat) KO2 is a very reactive, extremely stable chemical, reacting with the humidity and the CO2 of the exhalation air, releasing O2 and heat (exothermic reaction)

KO2 oxidises reliably all foreign substances

... and the breathing air is very dry!

MSA EUROPE 2005

AirElite 4h

KO2 - reaction:

2KO2 + CO2 + H2O >> [K2CO3*H2O] + 1.5 O2 + E: Increased exhalation = more CO2 + more H2O raise the oxygen generation! Or vice versa, less consumption reduces the O2-generation. At any time, more O2 is generated than used!

MSA EUROPE 2005

AirElite 4h

Flexible Service Time:The service time depends on the respiration perform- ance. High performance (heavy work) increases the oxygen generation, low performance (light work) extends the service time!

Sudden changes to high performance are compen-sated by the oxygen surplus!

The breathing air regeneration

Advantage:

O2-generation / CO2-absorption are effected exclusively by KO2:

in one stage, compressed oxygen and CO2 absorbers (soda lime), that must match each other, are not needed.

MSA EUROPE 2005

AirElite 4h

KO2 - B. A. do not need:

oxygen cylinders

oxygen pumps

deep freezers for ice production

MSA EUROPE 2005

AirElite 4h

KO2 offers:

optimal O2-surplus there is no compressed-O2-reserve, which may cause a CO2-intoxication if the soda lime cartridge is exhausted prematurely [CO2 -enrichment in the closed circuit]

a CO2 intoxication is impossible!

KO2 is:

totally breath controlled (no valves and pressure reducers that need maintenance)

simple in construction, has very safe function, and is very quickly ready for use.

almost maintenance free

long storable
