Oxygen Generators

High‑performance oxygen generators for industrial and medical applications

CompAir oxygen generators deliver a reliable, on‑site supply of high‑purity oxygen directly from compressed air. Using proven Pressure Swing Adsorption (PSA) technology, they provide a safe, cost‑effective and sustainable alternative to delivered oxygen, cylinders, or liquid oxygen systems.

From compact industrial units to high‑capacity medical and Multi‑SEP systems, CompAir offers one of the most comprehensive oxygen generator portfolios on the market.

Why choose CompAir Oxygen Generators?

  • On‑site oxygen generation – no deliveries, no storage risks
  • High oxygen purity up to 95%
  • Lower operating costs compared to cylinders and bulk oxygen
  • Continuous, reliable performance
  • Flexible configurations for any application or installation environment
  • Designed for efficiency, safety and long service life

PSA oxygen generator technology

CompAir oxygen generators use PSA (Pressure Swing Adsorption) to separate oxygen from compressed air. Nitrogen is adsorbed by the molecular sieve material, allowing oxygen to pass through and be delivered at the required purity and pressure.

Advanced control systems, integrated purity analysers and robust component design ensure stable oxygen output and long‑term operational reliability.

Designed for performance, safety and efficiency

All CompAir oxygen generators are engineered to operate reliably in ambient temperatures from 5°C to 50°C, with controlled outlet pressure, stable purity levels and continuous system monitoring. High‑quality materials, stainless steel piping and intelligent controls ensure safe operation in demanding environments.

Complete oxygen generation solutions

CompAir provides more than oxygen generators. We support complete oxygen systems, including:

  • Air treatment and filtration
  • Oxygen storage and buffering
  • Cylinder filling solutions
  • Monitoring and control integration
  • Lifecycle service and technical support
