We are offering High Quality Nitrogen Air Generator. Generator Introduction: 　　　Combined two gas generators, N2/Air generator is a perfect machine which combines to produce pure nitrogen and air. Compact size, easy operation. It is an idea gases resource. Little noisy, could drain water automatically. Greatly increased automation level. Three level purifications in order to produce ultra pure gas. Air generator inside with stainless steel storage tank. Could be used with kinds of gas chromatographs and other analysis instruments. 　　　 　　　 characteristics: 1. Nitrogen is produced also by water electrolysis technology. Membrane separation, through electrolysis water and air under KOH catalyst, to get pure N2 gas. 2. Air is powered by whole sealing silent air compressor. After purification, water, oil, dust and impurities are removed. Through pressure stable system, pure and silent air is 　 finally produced under stable pressure. N2 and air generator is an ideal equipment to replace high pressure gas cylinders. Technology Parameter NA-300/500 N2 Pure Air Output Flow Rate(ml/min) (Adjustable) 0--300/0--500 0---2000 N2 Output Pressure 4bar ( under stable pressure) Air Output Pressure 0--4bar ( under stable pressure) Output Purity 99.999% O2 content Water dew point: -56 oC Pure air Input Power 1Meghom/cm Working Noisy
