Nitrogen Gas Generator NNGG-100 is an on-site Pressure Swing Adsorption (PSA) unit that compresses atmospheric air using an air compressor. This unit delivers high purity nitrogen as the atmospheric air is padded through a tightly packed Carbon Molecular Sieve (CMS) column. As a result, only the smaller nitrogen molecules are passed through whilst the larger molecules of oxygen and other molecules are adsorbed by the CMS. As a result, these are an ideal solution for nitrogen requirements.
