In the military sector, oxygen must meet stringent requirements: mobility, safety, operational autonomy and immediate availability in emergency situations. Oxygen purity, reliability and continuity of supply are essential conditions for its use in an operational context.
Nitrogen also plays a key role in defense, notably for inerting tanks, inflating aircraft equipment and protecting sensitive equipment.
In this context, on-site production is an effective solution for the defense sector. Novair offers reliable, self-contained oxygen and nitrogen generators that meet the sector's needs.
The defense sector faces challenges in the use of oxygen and objectives to reconcile such as:
The current oxygen supply system relies mainly on cylinders filled far from the sites of use, resulting in heavy logistical dependence. This organization quickly shows its limits in contexts of prolonged commitments or flow disruptions.
The handling of pressurized gases is also a factor of complexity and risk in terms of mobility and safety.
Faced with the limitations observed, the current model is unable to meet the sector's needs. To address this, an effective solution is needed, centered on three fundamentals:
Technology from DS-PSA
A PSA-type oxygen generator is based on an air separation process using alternating pressurization (Pressure Swing Adsorption). Ambient air, composed mainly of nitrogen (71%) and oxygen (21%), is first compressed and filtered, then directed to molecular sieves. These retain the nitrogen and enable a flow of up to 95% pure oxygen to be obtained.
Developed by NOVAIR's R&D department, DS-PSA (Double Stage Pressure Swing Adsorption) technology is based on a patented double-stage adsorption process. This system eliminates the nitrogen, argon and pollutant residues remaining after an initial treatment phase. It thus achieves some of the highest levels of oxygen purity, up to 99.5%.
The Oxypure DS-PSA oxygen generator features this technology, specially developed to meet the most demanding requirements. It is also equipped with the exclusive OCS (Oxygen Concentration Stabilizer) system, ensuring optimum stability of oxygen flow and concentration, regardless of variations in demand.

Ionic technology
Ionic technology is the result of decades of research carried out in collaboration with NASA. It is based on a new-generation ceramic membrane capable of converting molecular oxygen into ionized oxygen atoms, thanks to an electrochemical process.
Ion technology is the result of decades of research carried out in collaboration with NASA.
On contact with this membrane, atoms are attracted to the front face of a ceramic crystal designed to let only oxygen ions through. A low DC voltage is applied to ionize the oxygen molecules, forcing the ions to migrate through the crystal. They then exit at the back of the membrane, where they instantly recombine into oxygen molecules.
ION from Novair is the world's first ionic oxygen generator, developed in partnership with NASA. Operating without compressors, consumables or maintenance, it is a totally innovative solution: compact, silent and exceptionally reliable. ION achieves purity levels ranging from 99.99% to 99.9999%, meeting the most demanding needs for ultra-pure oxygen.
Nitrogen is widely used in the military field for its inert properties, which guarantee the safety, reliability and performance of many systems. Producing nitrogen directly on site makes it possible to meet the strategic needs of armed forces while limiting the logistical constraints associated with cylinder transport.
NOVAIR designs and manufactures nitrogen generators with PSA (Pressure Swing Adsorption) and membrane technology, capable of producing dry, pure nitrogen from ambient air.
