Nitrogen generator refers to the equipment that takes air as raw material and uses physical methods to convert oxygen and nitrogen to obtain nitrogen. According to different classification methods, namely low-temperature air separation, molecular sieve air separation (PSA) and membrane air separation, nitrogen generators used in industry can be divided into three types. Nitrogen making machine is a nitrogen making equipment designed and manufactured according to pressure swing adsorption technology.

The nitrogen generator uses high-quality imported carbon molecular sieve (CMS) as adsorbent, and uses the principle of normal temperature pressure swing adsorption (PSA) to separate air to produce high-purity nitrogen. Usually, the two adsorption towers are connected in parallel, and the inlet pneumatic valve is controlled by the inlet PLC to operate automatically. The pressurized adsorption and decompression regeneration are carried out alternately to complete the nitrogen and oxygen separation and obtain the required high-purity nitrogen
