What is a PSA Oxygen Generator
A PSA Oxygen Generator operates based on the Pressure Swing Adsorption (PSA) principle, a process that separates oxygen from compressed air by using carbon molecular sieves (CMS) to selectively adsorb nitrogen under pressure. As air flows through the adsorption vessels, nitrogen is retained while oxygen passes through as the product gas, allowing continuous on-site oxygen production. The oxygen output can then be measured and regulated through system controls to ensure stable purity and flow for industrial applications.
A standard PSA oxygen generation system typically includes:
Air compressor: provides the compressed air source for oxygen production
Air treatment system: removes moisture, oil, and impurities to protect system stability
PSA oxygen generator unit: separates oxygen from compressed air
Oxygen storage tank: stabilizes oxygen pressure and flow for continuous use
Control system: PLC automatic control for stable and unattended operation

How PSA Oxygen Generator Working Principle
A PSA oxygen generator operates based on the pressure swing adsorption (PSA) principle, where oxygen and nitrogen are separated from compressed air using carbon molecular sieves (CMS). Under pressure, nitrogen molecules are preferentially adsorbed by the CMS, while oxygen passes through as the product gas.
When the pressure is reduced, the adsorbed nitrogen is released and the adsorption material is regenerated, allowing continuous cycling between adsorption and desorption. This alternating pressure process enables stable and continuous on-site oxygen production with controlled purity and flow output.
