AirGen Technologies offers advanced Membrane Nitrogen Gas Generators designed for high efficiency, compact , and consistent performance. Our systems are built for industries that need nitrogen purity ranging from 95% up to 99%
Whether you require a continuous nitrogen supply for a critical process or want to cut down cylinder dependency, AirGen Membrane Generators deliver an on-site solution that’s clean, quiet, and virtually maintenance-free.
How Membrane Nitrogen Generators Work
Clean Air Intake
Ambient air is first compressed and filtered to remove moisture, oil, and particles.
Membrane Separation
The clean, dry air passes through hollow fiber membrane modules. These fibers selectively allow oxygen, water vapor, and other gases to diffuse out, while nitrogen continues through the membrane.
Pure Nitrogen Delivery
The resulting nitrogen gas is delivered at the required purity and flow rate, stored in a buffer tank, and made available on demand.
Product Highlights
Purity: 95% to 99% nitrogen
Flow Rate: 1 Nm³/hr to 500 Nm³/hr
Pressure: 5 – 10 bar (adjustable)
Plug & Play: Simple to install and start using with a compressed air supply
Maintenance-Free: No moving parts = no operational hassle
Compact & Mobile: Skid-mounted for easy installation
Advantages of Membrane Technology
Energy Efficient
Lower air-to-nitrogen ratio compared to traditional systems in low-purity applications.
Quick Start-Up
Generates usable nitrogen within minutes of startup—for on/off operations only.
Low Maintenance
No adsorbent media, valves, or purge losses—cut maintenance costs drastically.
Membrane systems are simpler for Low Purity use only. However, PSA systems offer higher purities (up to 99.999%) and are better for critical or high-purity industrial needs.
