4.  MSA EUROPE 2005 AirElite 4h Circuit: Exhalation Inhalation è The exhalation air is enriched with oxygen è CO 2 and H 2 O are absorbed

5.  MSA EUROPE 2005 AirElite 4h KO 2 - function and reaction: 2KO 2 + CO 2 + H 2 O >> [K 2 CO 3 *H 2 O] + 1.5 O 2 + E (Potassium Hyperoxide) (Potassium Carbonate) (Heat)  KO 2 is a very reactive, extremely stable chemical, reacting with the humidity and the CO 2 of the exhalation air, releasing O 2 and heat (exothermic reaction)  KO 2 oxidises reliably all foreign substances ... and the breathing air is very dry!

6.  MSA EUROPE 2005 AirElite 4h KO 2 - reaction: 2KO 2 + CO 2 + H 2 O >> [K 2 CO 3 *H 2 O] + 1.5 O 2 + E:  Increased exhalation = more CO 2 + more H 2 O raise the oxygen generation! Or vice versa, less consumption reduces the O 2 -generation.  At any time, more O 2 is generated than used!

7.  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!

A. - Part 2: Chemical Oxygen (KO 2 ) Generating Type for work and rescue and vfdb 0802 (Regulations for the selection and use of Respiratory Protection Devices and Chemical Protection Suits for the Fire Brigades) including appendix D (Flame engulfment)

9.  MSA EUROPE 2005 AirElite 4h The breathing air regeneration Advantage: O 2 -generation / CO 2 -absorption are effected exclusively by KO 2 :  in one stage, compressed oxygen and CO 2 absorbers (soda lime), that must match each other, are not needed.

10.  MSA EUROPE 2005 AirElite 4h KO 2 - B. A. do not need:  oxygen cylinders  oxygen pumps  deep freezers for ice production

11.  MSA EUROPE 2005 AirElite 4h KO 2 offers:  optimal O 2 -surplus there is no compressed-O 2 -reserve, which may cause a CO 2 -intoxication if the soda lime cartridge is exhausted prematurely [CO 2 -enrichment in the closed circuit]  a CO 2 intoxication is impossible!

12.  MSA EUROPE 2005 AirElite 4h KO 2 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

13.  MSA EUROPE 2005 AirElite 4h What is happening in the KO 2 - canisters?  CO 2 -absorption  water absorption  O 2 -generation  chemical transformation of KO 2  generation of heat air cooled heat exchangers + maintenance free water cooling
