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..

本设备采用PSA变压吸附原理，利用碳分子筛在压力变化时具有分离空气中氮的能力，以空气为原料，将压缩空气经除油、干燥、过滤等净化处理后，送入双塔组成的吸附组件，压缩空气在一塔内经加压吸附后产生氮气，而另一塔在解吸再生，两塔交替循环，即可不断地得到纯度为98－99.9%的廉价氮气。
