This generator adopts PSA transforming absorpion,which uses carbon molecule to separate Oxygen and Nitrogen from air. It transfers compressed air,which is originated from air source, into absovbing untis formed by two tower after oil removing, drying, filtering, purifying of the air. The compessedair generates Nitrogen when it is transformingly absorbed in one tower, then it is sent to another tower for regeneration. It alternately circulates between two towers, which can unceasing achieve 98%-99.9% of pure and cheap Nitrogen..
