OBOGS and OBIGGS for L159 [ Return towards  Military training aircrafts  ]

Air Liquide has used its competences as main system manufacturer to provide Aero Vodochody with global recommendations (aircraft integration, technical systems specifications) to meet flight crew oxygen activation needs and tank inerting needs from knowledge of aircraft circuit characteristics.
Air Liquide has supplied the OBOGS system on board the L159s (oxygen concentrator, oxygen and anti-G regulator, plane seat connector, emergency source, junction plate) and the OBIGGS system.

The systems designed and manufactured by Air Liquide have represented a crucial technological advance given the low supply pressure available on the aircraft.
Our technology of electronically controlled motorized valves has made it possible to withstand the low pressure on board the L159 and to reach the performance levels specified by the plane-maker: percentage oxygen supplied by the concentrator, G-suit pressurization time and altimeter overpressure guaranteed by the regulator.
