The PMNG 1–3 uses hollow-fiber membrane technology to separate nitrogen from compressed air.

 

Step 1 – Compressed Air Intake
Dry, treated compressed air enters the nitrogen generator.

 

Step 2 – Membrane Separation
Compressed air passes through specially designed hollow-fiber membranes.

 

Step 3 – Selective Permeation
Oxygen, water vapor, and other gases permeate through the membrane walls.

 

Step 4 – Nitrogen Concentration
Nitrogen remains within the fibers and becomes concentrated at the outlet.

 

Step 5 – Nitrogen Delivery
The generated nitrogen is supplied continuously at the selected purity and pressure.

The PMNG 1–3 combines simple membrane technology, compact installation, and dependable on-site nitrogen generation.

 

High-Quality Membrane Separator

Advanced aluminum and fiber construction supports consistent nitrogen separation from compressed air.

 

No Moving Parts

The simple membrane design reduces mechanical complexity and maintenance requirements.

 

Compact Plug & Play Design

Integrated filters and controls provide an enclosed, easy-to-install nitrogen generation solution.

 

Flexible Purity

Produces nitrogen from 90% to 99.5% purity according to application requirements.

 

High-Pressure Nitrogen

Provides nitrogen pressure up to 12 bar without requiring an additional booster.

 

Compressed Air Savings

The optional Economizer automatically reduces air consumption when the target condition is reached.

Frequently Asked Questions

Find quick answers about the PMNG 1–3 membrane nitrogen generators, including purity, pressure, operation, installation, and applications.
The PMNG 1–3 can produce nitrogen from 90% to 99.5% purity, allowing users to select a purity level appropriate for their application.
Compressed air passes through hollow-fiber membranes. Oxygen, water vapor, and other gases permeate through the fibers, while nitrogen remains and is collected at the outlet.
The PMNG 1–3 can generate nitrogen at pressures up to 12 bar, without requiring an additional nitrogen booster.
The range includes PMNG 1, PMNG 2, and PMNG 3. At 95% purity, nominal free nitrogen delivery is 4.68, 9.36, and 14.04 Nm³/h respectively.
No. Its enclosed plug-and-play design includes integrated filtration and controls, allowing straightforward installation without specialist commissioning.
The standard system uses pneumatically controlled valves, while the optional nitrogen analyzer is battery-powered, minimizing external power requirements.
Yes. Atcorp can help Indian industrial buyers assess nitrogen purity, flow, pressure, and application requirements and assist with the appropriate membrane nitrogen generation solution, product supply, and service support.
