The compressed air passes through the air purification system to remove the impurities, such as oil, water and dust, and into the adsorption tower with zeolite molecular sieve. The nitrogen, carbon dioxide and water vapor in the air are adsorbed in large quantities by molecular sieves, and oxygen and nitrogen are separated because of the high diffusion rate of oxygen.
When the nitrogen and other impurities in the adsorption tower reach saturation, the pressure is reduced and the zeolite molecular sieve is regenerated and reused.
The two adsorption towers are operated under the control of PLC and continuously produce high quality oxygen.
