PSA nitrogen generator 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 on/off to realize two towers alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation and produces nitrogen with desired purity.

Applications:

1. Pharmacy: medicine packing, medical gas replacement and medical gas transport.
2. Biological technology, intermediate, etc.
