Membrane Systems - Membrane nitrogen generators are suitable for applications requiring medium to low purity up to around 99.9% and for very high flow rates, as high as 5000 m3/hr. from a single generator. Membrane generators when compared to PSA offer benefits such as compact footprint, lesser frequent maintenance. Thousands of hollow fibres are bundled and encased to form a high performance gas separation module which permeates oxygen, water vapor and other impurities out of its side walls while allowing Nitrogen to flow through its center and emerge as product
