A membrane nitrogen generator extracts the N₂ in the air supplied by a compressor so that it can be used for professional applications. The compressed air is pushed through a membrane filled with hollow fibers. Oxygen and water vapor dissipate through the fiber walls and are vented out. This leaves only the very dry nitrogen inside the fibers, pushed out on the other end of the membrane, ready for you to use.
Types: NGM+ & NGMs
Another way of generating nitrogen is through Pressure Swing Adsorption (PSA). PSA technology is the ideal and easiest method if you have an industry that requires very high purity levels. Pressure Swing Adsorption separates nitrogen molecules from oxygen molecules by trapping oxygen from the compressed air stream using adsorption. Adsorption takes place when molecules bind themselves to an adsorbent, in this case, the oxygen molecules attach to a carbon molecular sieve.

A nitrogen gas purifier is designed to enhance the purity of nitrogen generated on-site. It operates by taking lower-purity nitrogen from a generator and using a controlled hydrogen reaction to achieve a purity of 99.999% or higher. This two-stage process reduces the need for high feed air volumes, resulting in lower energy consumption and reduced emissions. Nitrogen purifiers are ideal for applications that demand very high purity, providing an efficient and reliable solution for on-site nitrogen production systems.
