NITROGAS® NG series is a range of top quality, efficient and reliable modular Nitrogen generators, current state of the art of PSA technology. Nitrogen is produced by selective adsorption on a bed of molecular carbon sieves starting from compressed air class 1.4.1 according to ISO 8573.1-2010 standard. The most important parameter measuring your generator’s efficiency is absolutely the AIR FACTOR, which is the ratio between inlet air and Nitrogen outlet flow rates. As a result, lower the air factor, lower the consumption of compressed air. This also means higher efficiency, with IMPRESSIVE SAVINGS on the electric bill. Be smart, choose the lowest air factor on the market with modular Nitrogen generators NITROGAS® NG series.
