What Is An N2 Generator?
An N2 generator is a machine that separates nitrogen molecules from compressed air. Nitrogen generators can be used in many commercial and industrial applications, including
- Improving the quality of a product
- Improving a process
- Preventing combustion as a safety measure
- Scientific equipment
Nitrogen generators can be stationary or mobile. Most on-site nitrogen generation systems used in industries are Pressure Swing Absorption (PSA) nitrogen generators.
Nitrogen generators can have purities of up to 99.999%. When choosing an N2 generator, it's essential to consider the purity level of nitrogen needed. For example, a 95 percent purity would be 95 percent nitrogen, 5 percent oxygen, and other inert gases.
Nitrogen generators can be sized based on inlet air temperature ranges. When sizing a pre-treatment package, the generator should be sized, and then a pre-treatment package that allows a 1 bar(g) pressure differential should be selected.
How Does A N2 Generator Work?
Nitrogen generators work by enriching nitrogen and oxygen. They use a process called pressure swing adsorption (PSA) to produce a continuous stream of nitrogen gas from compressed air:
- One vessel is filled with compressed air at high pressure.
- The compressed air passes through one vessel, where the sieve material adsorbs oxygen, water vapor, and other gases.
- The nitrogen molecules can travel through the adsorber–absorbent–containing vessel.
- The other vessel takes over immediately to ensure a continuous stream of nitrogen.
- When the pressure is released on the first vessel, the oxygen is released back into the air, and the process repeats itself.
- The nitrogen is then collected and stored for use.
Nitrogen generators can also use nitrogen membrane technology, which uses a high-selectivity membrane for nitrogen gas separation.

Through the process of adsorption, a nitrogen generator separates nitrogen molecules from other molecules by snatching oxygen and other gases from the combusted air stream. The process of continuous nitrogen generation via PAT uses no chemicals, thus reducing annual conumable cost.

The preventive wing The ad orption separation system was founded on this idea. While absorption involves the entire volume of the material, adsorption just involves the surface of the object. The ad orption method involves a liquid or gas molecule adhering to the ad orbent's surface.
P. A. Procedure21% oxygen, 78% nitrogen, 0.9% argon, and 0.1% rare ga e are all present in ambient air. A specific molecular ieve designed to add orb nitrogen under pressure is used in the P A procedure to create oxygen-enriched air that contains at least 93% oxygen.
P A purchases everything, whereas VP A purchases only oxygen. Due to the rugged design of the ad orption column, VP Ay systems are more susceptible to humid environments than P Ay systems. By using an oil-free blower, VP A avoids any oil carryover that is typical of oil-lubricated components.
