  1. AirElite 4h • The unique Closed Circuit Breathing Apparatus • 4 hours rated service time • Air regeneration with KO2 • Innovative Hi-Tech  MSA EUROPE 2005

  2. AirElite 4h Design: 2 KO2-canisters with automatic starters and service free cooling Exhalation bag Inhalation bag Surplus valve Blower assisted exhalation Battery Charging jack IC-Air control monitor  MSA EUROPE 2005

  3. AirElite 4h Design: Mask connector, automatic start, air hoses Consumption sensor Air flow routing and convection cooler Air distributor Particle filter Electronic terminal block  MSA EUROPE 2005

  4. AirElite 4h Circuit: Exhalation Inhalation • The exhalation air is enriched with oxygen • CO2 and H2O are absorbed  MSA EUROPE 2005

  5. 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

  6. 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

  7. 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!  MSA EUROPE 2005

  8. AirElite 4h 7,200 Litres Breathing Air for 4 hours at 30 litres / minute consumption DIN 58652 - Respiratory Protective Devices - Self Contained Closed Circuit B. A. - Part 2: Chemical Oxygen (KO2) 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)  MSA EUROPE 2005

  9. AirElite 4h 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

  10. AirElite 4h • KO2 -B. A. do not need: • oxygen cylinders • oxygen pumps • deep freezers for ice production Superfluous  MSA EUROPE 2005

  11. 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

  12. 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  MSA EUROPE 2005

  13. AirElite 4h • 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  MSA EUROPE 2005

  14. AirElite 4h Dimensions and weight: 600 mm 190 mm 360 mm 15 kg  MSA EUROPE 2005

  15. AirElite 4h Simple donning and doffing, also during use (breathing hoses under left arm)  MSA EUROPE 2005

  16. AirElite 4h Low cost training  TR-conversion kit for quick conversion of the operational AirElite into a trainer  MSA EUROPE 2005

  17. AirElite 4h Trainer •  dependent of the ambient air, • the P3 particle filter permits training in dense fog and nontoxic smoke  MSA EUROPE 2005

  18. AirElite 4h • and the IC-Air • manages and monitors the AirElite • clears the AirElite for the mission • warns of defects • counts the consumption • signals audibly and visually • alarms at immobility • offers a manual alarm  MSA EUROPE 2005

  19. Automatic immobility alarm > 95 dBa AirElite 4h and the IC-Air Test button and display illumination LED red/green Reset and calibration Manual immobility alarm  MSA EUROPE 2005

  20. AirElite 4h IC-Air display at start : Function check: display segments + + beep + light = OK Failures: 1 = battery 2 = starter / canister 3 = blower 8 = sensor 1 Beep  MSA EUROPE 2005

  21. AirElite 4h IC-Air display in use: Capacity indication: 100 % to 0 % Cylinder symbol : 8 segments 50 % residual capacity: short beep 15 sec 20 % residual capacity: LED red/green, interval beep, escape symbol 5 % residual capacity: LED flashing red, continuous beep, escape symbol flashing 0 % residual capacity: AirElite continues operation  MSA EUROPE 2005

  22. AirElite 4h Donning:  MSA EUROPE 2005

  23. AirElite 4h Inspection & Maintenance 6 months: visual check (lead seals) recharge battery check readiness (test button) (if fitted) 2 years: replace KO2-canisters training 5 years: replace battery consume originally packed KO2-canisters  MSA EUROPE 2005

  24. AirElite 4h • Cleaning & Disinfection • Mask • Breathing tubes • Breathing bag and valve control • Air distributor • Blower (spray disinfection only)  MSA EUROPE 2005

  25. AirElite 4h  MSA EUROPE 2005

  26. AirElite 4h Application Mining: Mine Rescue Teams The BA on site with the lowest maintenance requirements, the least periphery logistics, the fastest readiness, the most cost efficient training. The BA for quick missions!  MSA EUROPE 2005

  27. AirElite 4h Application Fire Brigade: The BA for the rare long-run missions! For stand-by rescue teams (2 AirElite for fire engines) Fire Brigades with tunnel missions (Railways/Subways/Road tunnels) Chemical industries, Refineries, Tank farms. Military facilities, Bunkers, Depots. Port authorities: onboard fire fighting Free from frequent service & maintenance!  MSA EUROPE 2005

  28. AirElite 4h USPs in a nutshell: • excellent breathing comfort: low resistances low air temperature dry breathing air • maintenance and ice free cooling • no periphery logistics (cylinders, pumps, ice) • low cost training • slim design, breathing hoses under the arm  MSA EUROPE 2005
