· Principle: The core of membrane separation is the physical process of gas separation by using the diffusivity of different components in the air on the polymer material. The polymer material is made into a mesoporous fiber film as thick as a hair, and the gas passes through the inside of the hole, and the end gets the nitrogen we need (90-99.9%). The side is the oxygen-rich gas discharged, and the concentration of oxygen-rich gas can reach 40%.

· Original imported film components :(PRISM) Prison, (UBE) Ube, (Generon) agile film;

· Fewer moving parts, low maintenance workload;

· Integrated engineering design of standard membrane components, quick installation and simple operation;

· Nitrogen product quality is stable and reliable;

· Nitrogen production can be increased;

· Clean nitrogen and low dew point.
