Membrane Nitrogen Generators

NGM, NGM+ & NGMS – Flexible, Efficient and Compact Nitrogen Generation

Atlas Copco’s membrane nitrogen generators offer a compact, plug-and-play solution for on-site nitrogen production with purities up to 99.9%. Whether you need a low-flow option or a high-efficiency system for demanding applications, the NGM, NGM+ and NGMS range offers the flexibility to match your exact requirements.

Why Choose Membrane Technology?

Using advanced hollow fibre membranes, these generators separate nitrogen from compressed air to deliver a continuous, dry, high-purity supply – ideal for applications like marine, oil & gas, tyre inflation, packaging, fire prevention and more.

A secure supply of nitrogen and oxygen

Whether your company is specialised in chemical manufacturing, electronics, laser cutting or food and beverage, a dependable supply of industrial gas is crucial. Compared to the on-demand delivery of gas bottles or tanks, on-site production of gas offers a wealth of advantages ranging from cost savings to continuous availability. Atlas Copco’s advanced nitrogen and oxygen generators offer you the ultimate solution: flexible on-site production of industrial gas at the lowest possible cost.

Compact and Cost-Efficient Nitrogen Generation

Membrane nitrogen generators are a robust and reliable alternative when ultra-high purity is not essential. With purity levels up to 99.5%, Atlas Copco’s membrane systems are perfect for applications where size, simplicity, and low maintenance are priorities.

How membrane technology works:
Compressed air passes through hollow fibre membranes, separating nitrogen from oxygen, water vapour and other gases. The result is a steady stream of dry nitrogen — ideal for low- to medium-purity applications.

Advantages of Atlas Copco’s membrane systems:

Purity from 95% to 99.5% (adjustable)
Up to 500 m³/h nitrogen flow
Compact, modular design
No moving parts – minimal maintenance required
Integrated filters and oxygen sensors
Dew point as low as -50°C

Models:

NGM – standard model for general use
NGM+ – improved efficiency and performance
NGMs – optimised for low flow requirements

Ideal for:

Plastic injection moulding
Fire prevention systems
Food storage and packaging
Tyre inflation and marine applications
Wastewater treatment and environmental uses

These systems are plug-and-play, requiring only dry compressed air, and can be installed directly on the production floor for maximum convenience.
