Vacuum Pressure Swing Adsorption (VPSA)

Vacuum Pressure Swing Adsorption (VPSA) is a process used in oxygen generators to produce high-purity oxygen by separating oxygen from ambient air. Unlike conventional Pressure Swing Adsorption (PSA), which uses pressurized air to separate gases, VPSA adds a vacuum phase to improve efficiency and reduce energy consumption. VPSA is widely used in medical, industrial, and environmental applications due to its efficiency and ability to produce a steady supply of high-purity oxygen.
