(1) Convenient and fast production of nitrogen: advanced technology, unique air distributor make the air distribution more uniform, efficient use of carbon molecular sieve, 20 minutes to provide qualified nitrogen

（2） Easy to use: compact equipment structure, overall skid mounted, small floor area, no infrastructure investment, less investment, just connect the power supply on site to produce nitrogen immediately

（3） It is more economical than other nitrogen supply methods: PSA process is a simple nitrogen supply method, using air as raw material, and the energy consumption is only the electric energy consumed by air compressor, which has the advantages of low operation cost, low energy consumption and high efficiency.

(4) Mechatronics design to achieve automatic operation: imported PLC control full operation, pure nitrogen flow pressure adjustable and continuous display, can achieve unattended

（5） Wide range of applications: protective gas for metal heat treatment process, production gas for chemical industry, nitrogen filling and purification of various storage tanks and pipes, production gas for rubber and plastic products, oxygen exhausting and fresh-keeping packaging for food industry, purification and disinfection for beverage industry, nitrogen filling and oxygen exhausting packaging for pharmaceutical industry, nitrogen filling and oxygen exhausting for containers, electronic components for electronic industry, Protective gas in semiconductor production process. Adjustable purity, flow rate, stable pressure, to meet different customer needs.
