PSA Oxygen Generation System
PSA Oxygen Generation System
The PSA oxygen generation system uses clean compressed air as the feed gas and high-quality zeolite molecular sieve as the adsorbent. Under controlled pressure conditions, oxygen is separated from air through pressure swing adsorption technology. Two adsorption towers operate alternately. One tower produces oxygen, while the other performs desorption and regeneration. Pneumatic valves are switched by a PLC controller, enabling continuous production of high-purity oxygen.

Product Details
Feed Air Pretreatment
- Compressed air passes through a refrigerated dryer and multi-stage filters to remove moisture, oil mist, and impurities. This ensures the inlet air is clean, dry, and oil-free, protecting the molecular sieve from contamination.
Adsorption Separation
- The pretreated air enters the adsorption towers filled with zeolite molecular sieve (ZMS). Under regulated pressure, the ZMS preferentially adsorbs nitrogen, carbon dioxide, and other trace impurities, while oxygen passes through the adsorbent bed as the product gas.
Regeneration Cycle
- Two adsorption towers work in alternating cycles. While one tower is in the adsorption phase to produce oxygen, the other undergoes depressurization to desorb impurities and achieve regeneration. PLC-controlled valves manage the seamless switching between towers to ensure a continuous and stable oxygen flow.
Post-Treatment and Storage
- Produced oxygen passes through fine filtration and sterilization. Oxygen boosters or oxygen storage tanks can be configured according to application requirements to ensure stable supply.
- Ambient temperature and low-pressure operation
Adjustable oxygen purity
- Standard oxygen purity reaches 93%±2%. Secondary PSA purification enables oxygen purity above 99.5% for industrial or medical applications.
Automated control
- Featuring "one-button start" and fully automated operation. Key parameters such as flow rate, pressure, and purity are monitored in real-time, supporting unmanned operation.
