Why should you switch to OBOGS?

  • To increase the operational reliability of the aircraft (unlimited cruising range: oxygen is no longer a limiting factor for flight range)
  • To reduce ground and logistics supports
  • To avoid fire and explosion hazards in relation to logistics and the use of liquid or high pressure gaseous oxygen
  • To improve flight safety

The pros of Air Liquide technology and design:

  • Responsive and accurate regulation of the gas
  • Wide range of operating pressure, beyond the standard values (particularly at very low inlet pressure)
  • Eased system diagnosis and management with no impact on reliability (Continuous Build-In Test)
  • Very adaptative and flexible design in order to meet any requirement for control of performances: flow, pressure, oxygen content schedules
  • Integrated monitoring device possible in option
  • Compact lightweight system

The pros of Air Liquide expertise:

Our expertise in the fields of gases separation, analysis and storage allows to offer a global solution adaptable to your needs, integrating:

  • Definition of specifications
  • Design
  • Manufacturing
  • Integration
  • Full support

Main technical characteristics

  • Weight of concentrator: < 10.3kg
  • Length x width x height ≈ 350 x 350 x 200mm
  • Minimum inlet pressure: < 5 psig relative to cabin pressure 
  • Electrical supply: 28 Vdc or 115 Vac 
  • Power consumption < 5 A

Oxygen analyzer

As part of an OBOGS, the oxygen analyzer ensures that the system is in good working order. It analyzes the oxygen-enriched) gas and sends an electrical signal reflecting the quantity of oxygen as a percentage or in partial pressure. The O2 analyzer is fitted with a zirconium oxide sensor to ensure its precision and reliability. It can operate at a wide range of pressures, from a few millibars to several bars and temperatures of up to 300°C.
