It uses carbon molecular sieve as sorbent, produces nitrogen by making use of the PSA principle. Under certain pressure, carbon molecular sieve has different oxygen/nitrogen adsorption capacity, i.e. much more oxygen adsorption capacity than nitrogen adsorption capacity.PLC controls pneumatic valve open/close to realize two towers alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation and produces nitrogen with desired purity.
