Working PrincipleFollowing the principle of pressure swing adsorption, high-quality carbon molecular sieve is used as the adsorbent. Under certain pressure, due to the dynamic effect, the diffusion rate of oxygen and nitrogen on the carbon molecular sieve is different. The oxygen molecules are adsorbed by the carbon molecular sieve in large quantities. Nitrogen molecules are enriched in the gas phase to achieve oxygen and nitrogen separation. Since the adsorption capacity of carbon molecular sieve for oxygen varies significantly with pressure, reducing the pressure can adsorb the oxygen molecules adsorbed by the carbon molecular sieve, so that the carbon molecular sieve can be regenerated and reused. Two adsorption tower processes are adopted, one is for adsorption and nitrogen production, and the other is for desorption and regeneration, alternating cycles and continuous production of high-quality nitrogen.

| No | MAIN PART | FUNCTION | ||
| 1 | Air compressor | Air is used as raw material to collect & compress air to 8 bar, (Screw type) | ||
| 2 | Refrigerated dryer | The standard configuration removes moisture and impurities in the air, so that the air dew point reaches -20°C (the intermediate configuration uses an adsorption dryer, and the dew point reaches -40°C; the advanced configuration uses a combined dryer, and the dew point reaches- 60ºC). | ||
| 3 | Precision Filter | A/T/C three-stage filter to remove oil, dust and impurities. | ||
| 4 | Air buffer tank | Store pure and dry air for subsequent adsorption and separation of oxygen and nitrogen as raw material storage. | ||
| 5 | Adsorption tower | A&B adsorption tower can work alternately, regenerating adsorption, filling sodium molecular sieve to filter out oxygen molecules. | ||
| 6 | Analyzer | Real-time monitoring and analysis of oxygen & nitrogen purity, indicating that the equipment is working normally and alarming. | ||
| 7 | Valves & pipelines | Intelligent control valves realize automatic operation of equipment, PLC control, SUS304 pipelines. | ||
| 8 | Gas Buffer Tank | Store oxygen & nitrogen with qualified purity, which can be directly piped or used for bottle filling. | ||
| 9 | Pressure regulator | Adjust and temperature the outlet pressure of oxygen & nitrogen (3-6 Bar). | ||
| 10 | Dust filter | Remove the dust brought by molecular sieve in oxygen & nitrogen | ||
| 11 | Check valve | Prevent oxygen & nitrogen back flow | ||
| 12 | Gas Booster | Pressurize the oxygen&nitrogen to the filling pressure, generally 150bar or 200bar. | ||
| 13 | Filling Manifold | Split high-pressure oxygen & nitrogen into each gas cylinder | ||
1) Metallurgy, metal processing industry
Widely used in metal heat treatment, powder metallurgy, magnetic materials, copper processing, metal wire mesh, galvanized wire, semiconductor, powder reduction and other fields. Some of these industries require nitrogen with a purity greater than 99.5%, while others require high-quality nitrogen with a purity greater than 99.999%.
2) Chemical industry, new material industry
Mainly used in chemical, spandex, rubber, plastic, tire, polyurethane, biotechnology, intermediates and other industries, many chemical industries do not have high requirements for nitrogen purity, many purity greater than 98% can be used. Glass manufacturing, preventing surface oxidation and furnace cooling during glass manufacturing, etc.
Gas protection during float glass production to prevent oxidation of the tin bath.
Rubber industry: packaging and storage of rubber; Tire production, etc.
Fertilizer industry: nitrogen fertilizer raw materials; Displace, seal, wash, protect catalyst and other gas.
Plastics industry: pneumatic transmission of plastic particles; Oxidation prevention in plastic production and storage.Rubber industry: packaging and storage of rubber; Tire production, etc.
In chemical fiber production, high-purity nitrogen is often used as a protective gas to prevent chemical fiber products from being oxidized and affecting the color during production. The higher the purity of nitrogen, the more beautiful the color of the chemical fiber product.
3) Food and pharmaceutical industry
Mainly used in food packaging, food preservation, pharmaceutical packaging, pharmaceutical replacement air, pharmaceutical conveying atmosphere. The food industry does not have high requirements for nitrogen, many more than 98% purity can meet the requirements, the pharmaceutical industry usually requires nitrogen with a purity of 99.9%. Medicine and health Pharmaceutical raw materials, drug nitrogen-filled packaging, transportation and Chinese herbal medicine mothproof, anti-corrosion protection.
Pharmaceutical nitrogen equipment (nitrogen purity 99.99%) is a pharmaceutical nitrogen generator developed according to GMP specifications based on the experience of professional research and development of pressure swing adsorption nitrogen generator in recent years, which has low operating cost, stable nitrogen purity and easy operation compared with cylinder nitrogen (or liquid nitrogen) in use.
Pharmaceutical industry: nitrogen-filled storage and preservation of traditional Chinese medicines (such as ginseng); Western medicine injection nitrogen filling; nitrogen filling of storage and containers; Air source for pneumatic transportation of pharmaceutical materials, etc.
Food industry is used for food preservation and food storage, food drying and sterilization, food flash freezing, etc. Nitrogen-filled storage and preservation of fruits, vegetables, tea, etc. is also a state-of-the-art method. 
4) Electronics industry, SMT industry
In the production process of electronic components and semiconductor components, nitrogen with a purity of more than 99.999% is required as a shielding gas.
Mainly used in wave soldering, reflow soldering, crystal, piezoelectric, electronic ceramics, electronic copper strip, batteries, electronic alloy materials and other industries. The electronics industry generally has high requirements for nitrogen, usually requiring 99.9% or 99.99%, and more than 99.99% nitrogen.
5) Other areas of use In addition to the above industries, nitrogen generators are also widely used in coal, petroleum, oil transportation and many other fields. With the advancement of science and technology and the development of society, the use of nitrogen is more and more extensive, on-site nitrogen (nitrogen generator) with its investment saving, low cost, easy to use and other advantages have gradually replaced liquid nitrogen evaporation, bottled nitrogen and other traditional nitrogen supply methods.
