Low Maintenance and High Reliability
With no moving parts or complex control systems, membrane nitrogen generators are virtually maintenance-free, providing highly reliable operation even in remote or unattended facilities.
Membrane Nitrogen Generators
Quiet, compact, and maintenance-free on-site nitrogen generation
Air Kraft supplies a range of Atlas Copco NGM and NGM+ Membrane Nitrogen Generators, offering a simple, space-saving solution for continuous nitrogen supply. These units are ideal for industries that require medium to high flows of nitrogen at purities up to 99% - without the complexity or servicing needs of PSA systems.
Whether you're blanketing sensitive materials, purging tanks, or preserving product quality during packaging, membrane nitrogen generators provide a clean, efficient, and cost-effective source of on-site gas.
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.
How Membrane Technology Works
Membrane nitrogen generators use hollow fibre membranes to separate nitrogen from compressed air. As the air passes through the membrane, oxygen, water vapour and other gases permeate through the fibres, while nitrogen continues along the flow path and is collected as product gas.
This passive, mechanical process means no moving parts, virtually no maintenance, and a long service life - making membrane technology ideal for remote installations or where operational simplicity is key.
