3 min read


PSA (Pressure Swing Adsorption) technology has revolutionized the medical industry by offering a cost-effective and reliable source of oxygen for various healthcare applications. This article aims to comprehensively explore PSA oxygen technology, its working principle, applications, advantages, and key players, with a focus on enhancing knowledge for anyone interested in this topic.

What is PSA Oxygen Technology?

  • Overview of PSA technology for extracting oxygen from air for medical use
  • Eliminates need for traditional oxygen cylinders, making it more convenient, affordable and eco-friendly

Working Principle of PSA Oxygen Generation

  • Uses adsorption characteristics of molecular sieves to separate oxygen from other gases in air
  • Employs two adsorption vessels and a cycling process to generate continuous supply of high-purity oxygen

Benefits of PSA Oxygen in the Medical Industry

  • Provides reliable, on-demand oxygen supply
  • Eliminates dependence on external oxygen production
  • Decreases logistical challenges of cylinder delivery
  • Reduces oxygen costs
  • Ensures consistent purity levels

Applications of PSA Oxygen in Healthcare

  • Widely used to support anesthesia, ICUs, respiratory therapy, neonatal care, emergency medicine, wound healing, and more
  • Crucial role in disaster response and remote medical facilities

Understanding the PSA Oxygen Generation Process

Adsorption Phase

  • Explanation of how oxygen selectively adsorbs onto the molecular sieve material in the pressurized vessels

Desorption Phase

  • Explanation of how decreasing pressure causes adsorbed oxygen to detach and be released from the vessels

Purging Phase

  • Explanation of how the vessel is purged to prepare for the next adsorption phase

Factors to Consider when Choosing PSA Oxygen Generators

Purity and Flow Rate Requirements

  • Important to select generators that meet the purity and capacity needs of the application
