Imashini itanga ubuvuzi bwa ogisijeni hamwe na tekinoroji ya adsorption (PSA) nkishingiro, kugirango ikure ogisijeni mu kirere cyibikoresho bishya, gukoresha tekinike ya molekuline yumubiri hamwe na tekinike ya desorption muri generator ya ogisijeni itanga imizigo, mugihe umuvuduko mwikirere irashobora kuba azote adsorption, ogisijeni isigaye idakusanyirijwe hamwe, ihinduka nyuma yo gutunganya ogisijeni yuzuye.Igikorwa cyihariye cyo gukora nuko umwuka wafunzwe usukurwa nicyuma cyoguhumeka ikirere hanyuma ukinjira muminara ya adsorption unyuze mumashanyarazi.Mu munara wa adsorption, azote ihindurwamo na sikeli ya molekile, ogisijeni irundarunda hejuru yumunara wa adsorption mu kigega kibika ogisijeni, hanyuma ikanyura mu gukuraho umunuko, kuyungurura ivumbi hamwe no kuyungurura sterisile yujuje ubuziranenge bwa ogisijeni yo kwa muganga.Ibice byingenzi bigize: ikigega cyo mu kirere, compressor yo mu kirere, imashini yumisha ikonje, umushyitsi wa ogisijeni, ikigega cya ogisijeni n'ibindi.
