The PSA Oxygen Generator is an air separation unit which is based on molecular sieves selective adsorption of nitrogen from air and can continuously generate gas oxygen with a purity 90~ 95% at ambient temperature and the adsorbed nitrogen can be desorpted by decreasing the adsorbed bed pressure resulting cyclical adsorption desorption operation. Area: 900m2 Oxygen purity: 90 ~ 95% Oxygen pressure: 1.2 Mpa Oxyge output: 100~10000NM3 / h Installed Capcity: 405KW£»380V 50Hz.
