PSA / VSA oxygen generators produce pure oxygen at 90% to 93% concentration by removing nitrogen from the air by using an absorbent.

There are two types of oxygen generators: PSA （Pressure Swing Adsorption） and VSA （Vacuum Swing Adsorption）.

Since VSA oxygen generators are simple to start and stop, this technology is gradually replacing conventional low-temperature separation systems.

**&lt;Features&gt;**  
• Automatic energy saving by accounting for fluctuation in oxygen usage  
• Flexible oxygen supply (50 - 4,000 Nm3/h)  
• Lower cost on-site production compared with the purchase of liquid oxygen  
• Easy, automated operation   
• Remote monitoring and control system (optional)
