Working  Principle

 

According to the compressed air of gas in membrane module of the solubility and diffusion coefficient difference, lead to gas in through the membrane module of relative permeability at different speeds, seepage velocity faster gas such as hydrogen, oxygen through the membrane module, in the membrane penetration side be enrichment, and infiltration rate slower gas such as nitrogen, argon, etc, in the membrane of the viscous flow side be enrichment, achieve the purpose of separation of oxygen and nitrogen.

 

+Increase the membrane module can enlarge system produce nitrogen.

+Imported PLC intelligent program controller,automatic operation.

+Purity IN95-99.9% between straight by flow freely adjust

+Import original membrane module ,start to normal supply of only a few minutes,membrane group life can be for ten years.

+Light weight, compact structure, convenient installation
