ONH Systems industrial oxygen generators operate on the Pressure Swing Adsorption (PSA) principle. This technology separates oxygen from compressed air using a molecular sieve that selectively adsorbs nitrogen under pressure.
Each unit consists of two adsorption columns filled with synthetic zeolite. As compressed air enters one column, nitrogen is retained by the adsorbent, while oxygen flows to the user. Meanwhile, the second column regenerates, ensuring a continuous oxygen supply.
Operating Principle
- Zeolite adsorbent selectively retains nitrogen molecules, releasing oxygen. With proper air filtration, its service life is virtually unlimited.
- Dual-column system: one column operates while the other regenerates, ensuring uninterrupted production.
- Continuous cycle delivers stable oxygen purity up to 94 ± 2 %.

Advantages of ONHS PSA Oxygen Generators
- Lower operating costs: on-site production of the exact oxygen volume required eliminates dependence on external suppliers. Most clients achieve ROI within 2 years.
- Reliable supply: uninterrupted, on-demand oxygen generation.
- Enhanced safety: no heavy cylinders, no high-pressure risks, no cryogenic storage of flammable gases.
- No logistics constraints: save time by avoiding repeated orders, invoices, and transport procedures.
- Eco-friendly: reduces environmental impact by eliminating oxygen deliveries via road transport.
