For the difference of solubility and diffusion in the hollow fiber membrane, the penetration rates of mixed gas vary at traversing the polymer membrane, the product gas N2 is separated from compressed air. Nitrogen generator by membrane separation is based on above principle to produce high purity N2 from raw material of compressed air.

The devices are suitable for the users who demand a great lot of N2, and not concerning the purity .

Equipment Features
　　 1.With high separation coefficient , the area of hollow fiber membrane is larger than surface;
　　 2.No valves and other moving parts, operation without any noise;
　　 3.The life of membrane group could be maintained more than 10 years;
　　 4.Standard models, nitrogen generator could be parallel for additional nitrogen output;
　　 5.Covering less, can be made mobile, wall-mounted, without investment in infrastructure, low cost of installation;
　　 6.Switch-rapid, easy to operate, could produce qualified N2 in 3 minutes after booting.
