AirElite 4h
The unique Closed Circuit Breathing Apparatus
4 hours rated service time
Air regeneration with KO2
Innovative Hi-Tech
MSA EUROPE 2005
AirElite 4h
Design:2 KO2-canisters
with automatic starters
and service free cooling
Exhalation bag
Inhalation bag
Surplus valve
Blower assisted exhalation
Battery
IC-Air control monitor
Charging jack
MSA EUROPE 2005
AirElite 4h
Design:
Electronic terminal block
Mask connector, automatic start, air hoses Consumption sensor
Air flow routing and convection cooler
Air distributor
Particle filter
MSA EUROPE 2005
AirElite 4h
Circuit:
Exhalation
Inhalation
The exhalation air is enriched with oxygen
CO2 and H2O are absorbed
MSA EUROPE 2005
AirElite 4h
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!
MSA EUROPE 2005
AirElite 4h
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

What is happening in the KO2-canisters?
CO2-absorption
water absorption
O2-generation
chemical transformation of KO2
generation of heat air cooled heat exchangers + maintenance free water cooling
