PSA Oxygen Generator Theory:
PSA oxygen generator is an automatic equipment which separate oxygen from air. Oxygen generator is constructed according to the principle of operation PSA (pressure swing adsorption) and it compressed by two absorption towers filled up with molecular sieve. The two absorption towers are crossed by compressed air (previously purified oil, water,dust, etc) . Molecular sieve’s surface and inner surface and interior are filled with micro pores. Nitorgen molecule has a faster diffusion rate and oxygen molecules has a slower diffusion rate. Oxygen molecules are enriched in the end from the absorption tower.While one of the absorption tower produce oxygen, the other one release nitrogen gas to atmosphere. The process comes in cycle way.

| oxygen purity | 93%±2 |
| Pressure of outlet O2: | 0 - 5.5bar |
| Installed power: | 0.8kw |
| Power supply: | 220V/60Hz |
| Weight: | 2.3 Tons |
| Dew point: | -45℃ |
Features:
1).Full Automation
All systems are designed for un-attended operation and automatic oxygen demand adjustment.
2).Lower Space Requirement
Can be customized design and assembled on the skid.
3).Fast Start-up
Start-up time is only 5 minutes to get desired oxygen purity.So these units can be switched ON&OFF as per oxygen demand changes.
4).High Reliabiity
Very reliable for continuous and steady operation with constant oxygen purity.Plant availability time is better than 99% always.
5).Longer Service Life
Efficient molecular sieve packing, tighter, more solid, and longer service life;
6).Adjustable
By altering flow,you can deliver oxygen with precisely the right purity.
