Medical Oxygen

Medical oxygen generator supply systems for use in medical gas distribution systems are medical devices that provide medical oxygen production at the point of use from ambient air. They produce a gas whose specifications are defined by the monograph of the European Pharmacopoeia Oxygen 93%.

Medical oxygen is considered a medicine.

Since 1926 and with its know-how since 1970 in the manufacture of adsorption air treatment systems, MIL’S has developed a complete process, from the air plant to the oxygen generator according to various processes (PSA and VPSA) as well as other essential accessories to provide medical oxygen on site.

Requirements recall of pharmacopeia for oxygen :

  • nominal concentration of oxygen 93% ± 3% V/V
  • carbon monoxide concentration ≤ 5 ml/m3
  • carbon dioxide concentration ≤ 300 ml/m3
  • oil concentration ≤ 0,1 mg/m3
  • water vapor concentration ≤ 67 ml/m3
  • nitrous gases concentration NO/NO2 ≤ 2 ml/m3
  • sulfur dioxide concentration SO2 ≤ 1 ml/m3

Our medical oxygen generators use two technologies: PSA (Pressure Swing Adsorption) or VPSA (Vacuum Pressure Switch Adsorption) to produce OXYGENE 93 Pharmacopoeia on site.

The PRO2XY 5 and 12 bar medical oxygen generator is based on PSA technology, an air separation technology that uses ambient air as the only raw material.

The PRO2XY 5 and 12 bar medical oxygen generators deliver oxygen on demand or continuously with a purity of up to 95% at a flow rate of 4 to 35 Nm3 / h.

Like all our other products, our oxygen generators PRO2XY have the CE mark MD class IIB and meet the ISO 7396-1 2016 standard, the European pharmacopoeia OXYGENE 93 and the NFS 95-175

The PRO2XY VAC medical oxygen generators use VPSA technology.

From the ambient air composed of approximately 78% nitrogen (N2), 21% oxygen (O2) and 1% argon (Ar), the PRO2XY VAC medical generator provides a typical concentration 95% oxygen, the remainder being mainly argon. The two tanks of adsorbent (or molecular sieves) take in turn the nitrogen present in the air introduced at the bottom of the tanks. Oxygen concentrates upward and is recovered at the top of the tanks. Thus, the SRP booster sends air into the two adsorbent tanks and the vacuum pump regenerates the sieve by removing nitrogen and moisture.

The VPSA PRO2XY VAC 5 and 12 bar medical oxygen generators deliver oxygen continuously or on demand with a purity of up to 95%. VPSA technology is used by MIL’S oxygen generators at the oxygen concentration present in the air. This makes it possible to produce dry oxygen from 90% to 95% concentration continuously, the remainder of the product obtained being composed mainly of argon and nitrogen.

The PSA PRO2XY medical oxygen generators and the VPSA PRO2XY VAC medical oxygen generators can be placed in a cabin (composite) or in containers (metal) designed for outdoor installation. This equipment includes two compartments, one dedicated to the supply of air, the other to the production of medical oxygen.

The company is also ISO 13485, 9001, 14001 certified.
