Working Principle 

According to the press swing adsorption theory,the high quality carbon molecular sieve as the adsorbent, under the certain pressure, carbon molecular sieve has different oxygen/nitrogen adsorption capacity,the oxygen is adsorbed largely by the carbon molecular sieve, and the oxygen and nitrogen is separated. 
Since the adsorption capacity of the carbon molecular sieve will be changed according to different pressure, once lowering the pressure, the oxygen will be desorbed from the carbon molecular sieve. Thus, the carbon molecular sieve is regenerated and can be recyled.
We use two adsorption towers, one adsorb the oxygen to generate nitrogen, one desorb the oxygen to regenerate the carbon molecular sieve, cycle and alternation,on the basis of PLC automatic process system to control the pneumatic valve open and colse, thus to get the high quliaty nitrogen continuously.
