Vacuum Pressure Swing Adsorption (VPSA) is an advanced gas separation technology that utilizes the different selectivity of adsorbents for gas molecules to separate gas components. Based on the principle of VPSA technology, the VPSA-O2 units adopt the special adsorbent (model: PU-8, provide material inspection report) to enrich the oxygen in the air and supply it to the user.
