Nitrogen Generators

NGM 1-7: Membrane nitrogen generators, capacity 1.4-140 l/s, flow 5-500 Nm³/h, purity 95-99%

Atlas Copco’s NGM membrane nitrogen generators provide a cost-effective, reliable and secure supply of nitrogen. The nitrogen generator’s working principle is based on membrane air separation. The membrane allows nitrogen to pass and other gases (like oxygen, water vapor and CO2) to permeate. The NGM series delivers flows from 5 to 500 Nm3/h and purities from 95% to 99%. These features make the NGM ideal for applications such as fire prevention, tire inflation, oil & gas, marine, packaging and more.
