Nitrogen Generator Membrane

UCNM Nitrogen Generators utilize proprietary membrane sepration technology. The membrane divides the air into two streams: one is 95%-99.9% pure nitrogen and the other is oxygen –rich with carbon dioxide and other trace gases. The generators separate air into its component gases by passing Inexpensive, conventional compressed air through bundles of individual hollow fiber, semipermeable membrane. Each fiber has perfectly circular cross section and a uniform bore through its center. Because the fibers are so small, a great many can be packed into a limited space, providing an extremely large membrane surface area that can procuce a relatively high volume product stream.Compressed air is introduced to the center of the fibers at one end of the module and contacts the membrane as it flows through the fiber bores. While oxygen, water vapor and other trace gases permeate the membrane fiber and are discharges through a permeate port, the nitrogen is contained within the hollow fiber membrane, and flows through the outlet port of the module. Water vapor also permeates through the membrane; therefore, the nitrogen product gas is very dry.
