We take air as raw material and utilize the carbon molecular sieve (CMS) as absorbent. CMS 

absorption of oxygen in air is much larger than its absorption of nitrogen under certain pressure, 

thus through programmed on and off process of the automatic pneumatic valves, tower A and B 

will work alternate to achieve pressurized adsorption and depressurize desorption, complete the 

separation of Oxygen and Nitrogen and reach the targeted purity of Nitrogen.

● Fast operating, provide the required nitrogen gas within 15~30 minutes.
● Equipment operating automatically, no workers needed in the whole production process.
● Molecular sieves are effeciently filled, more compact, resulting in longer life span.
● Tailor made the nitrogen generator according to customers’ individual project specifications 

and requirements, with high capacity, pressure and purity ranges. 
● Compact construction, advanced high-tech process, safe and reliable, low consumption.

● Customized pressure, purity and capacity ranges.

● Capacity —— 3～5500Nm³/hr
● Purity —— 95%～99.9995%
● Pressure —— ≤7bar (Adjustable)
● Dew point——≤－40℃（Adjustable）

Note: Higher oxygen content and dew point needed, please contact us for more details about NP 

series nitrogen purification system.
