Features: 
1、Skid-mounted structure, easy installation, small occupying area. 
2、The unique process and adsorber structure provide high nitrogen output rate, high recycling rate and obvious energy-saving effect. 
3、The top-down gas flow, exclusive rate control and side-vibrating loading and sieving guarantee the static operation of molecular sieve without powdering or adding. 
4、The air pretreatment system is equipped with dehydrator, degreasing devices, deduster and voltage regulator. The clean air source insures long service life and high adsorption efficiency of adsorbers. 
5、Modular design, one-finger operation, simple maintenance, no extra care, perennial safe autorun. 
6、The internal and external surfaces of pressure-bearing components are derusted by sand blasting and degreased in order to extremely extend the service life of pneumatic components and detective components. 
7、More suitable for small oxygen use.
