Imashanyarazi ya VPSA Oxygene ni moteri ya adsorption hamwe na generator ikuramo umwuka wa ogisijeni. Umwuka winjira muburiri bwa adsorption nyuma yo kwikuramo. Umuyoboro udasanzwe wa molekuline uhitamo nitorojeni, dioxyde de carbone n'amazi ava mu kirere. Icyuma cya molekile noneho kijugunywa mugihe cyimyuka, ikongera gukoresha ogisijeni yuzuye (90-93%). VPSA ifite ingufu nke zikoresha, zigabanuka no kongera ingano yibihingwa.
Shanghai LifenGas VPSA itanga amashanyarazi iraboneka muburyo butandukanye. Imashini imwe ishobora kubyara 100-10,000 Nm³ / h ya ogisijeni ifite 80-93%. Shanghai LifenGas ifite uburambe bunini mugushushanya no gukora inkingi ya radiyo ya adsorption, itanga umusingi ukomeye kubihingwa binini.
