A wide range of solutions for the aeronautical industry
Why choose Air Liquide as your gas supplier for Aviation?
High quality gases for aviation, to ISO standards
Aircraft manufacturers and their subcontractors need high quality gases and equipment to carry out and simplify their manufacturing and maintenance activities. Air Liquide gas offers are reliable, reproducible and comply with the most stringent regulations as well as their evolution.
Our products are reliable, repeatable, and compliant with regulations set by the National Aerospace and Defense Contractors Accreditation Program (NADCAP).
Used in the manufacture of components and aircraft maintenance, our gases are compatible with new ultralight composite materials. For metals or light materials such as composites, Air Liquide offers solutions for manufacturing structures and equipment for aviation.
Metal fabrication for aviation
Heat treatment is a process that optimizes the properties of metals intended for the manufacture of various components (landing gear, engine pylons, turbines or even engines). Our ALNAT™ metal heat treatment solutions include gases, processing equipment and related services to ensure treatment uniformity and reproducibility. We also supply gases and their solutions for surface treatment processes, such as HVOF (supersonic flame spraying) or plasma assisted deposition, to give parts their final properties.
Arc welding is also essential in the fabrication of various metal components of an aircraft. For this step, our shielding gases are among the most reliable in the industry. Compliant with ISO standards and used for welding and backing, ARCAL™ is our flagship brand of arc welding gases (argon and argon-based mixtures).
Air Liquide's offer for the aeronautics industry is a complete solution adapted to the needs of our customers. It includes gas, the technical services of our experts as well as an extensive range of the best welding products and safety equipment.
Global network of experts
With an international network of experts specialized in heat treatment, welding and surface hardening, Air Liquide is ready to support your development and your innovations.
We are involved in all stages of aircraft manufacturing that require expertise in materials processing, welding and composite implementation.
We also offer associated services and equipment for manufacturing, assembly and material processing operations.

Focus on onbaord gas generation systems
Backed by its mastery of air gas separation technologies, Air Liquide is a major partner for civil and military aviation in the design of onboard gas generation systems.
On-board gas generation with OBOGS
The autonomous generation system OBOGS (On Board Oxygen Generating System) produces oxygen-enriched air directly and unlimitedly on board aircraft. This equipment makes it possible to cover all the physiological needs of pilots (breathing gas and anti-g protection). The electronic control of all the functions of the OBOGS offers great flexibility in the management of operating settings (altimetric overpressure laws, monitoring law, etc.).
Selected on numerous military aeronautical programs, Air Liquide's OBOGS should equip more than half of new generation aircraft. From now on, it also equips civil aircraft.
The OBIGGS for the protection of fuel tanks
For its part, the OBIGGS range (On Board Inert Gas Generating System) improves the safety of airplanes and helicopters thanks to an inerting system eliminating the risk of fire or explosion of fuel tanks. Part of the oxygen contained in the tank is replaced by nitrogen-enriched air, generated on board by the OBIGGS, thus making the fuel vapors non-flammable. This equipment does not require any calibration or logistics before the flight.
Aircrew respiratory protection equipment
Finally, Air Liquide designs and manufactures respiratory equipment (hoods-PBE: Protective Breathing Equipment) specially designed for commercial flight personnel having to operate in a polluted atmosphere following an incident (smoke on board, cabin contaminated by toxic fumes, etc.). These anti-smoke hoods, which use aeronautical quality compressed oxygen, provide on-board personnel with the protection and autonomy necessary for the smooth running of evacuation operations in the event of an incident.
Made of Nomex fabrics providing optimal protection in the event of fire and fitted with an anti-fog and anti-scratch treated polycarbonate visor, the hoods do not require any adjustment when fitted. A phonic membrane makes it possible to maintain communication with the means available on board.
