I-oxygen concentrator ngumatshini ovelisa ioksijini. Umgaqo wayo usekelwe kwiteknoloji yokwahlula umoya. Okokuqala, umoya uxinzelelwe kubuninzi obuphezulu. Emva koko, ukuthatha ithuba leendawo ezahlukeneyo zokujiya zamalungu omoya, irhasi{3}}ukwahlulwa kolwelo kwenzeka kwiqondo lobushushu elithile. Ekugqibeleni, i-distillation yahlula umoya kwi-oksijini kunye ne-nitrogen. Ngenxa yokuba isetyenziselwa ukuveliswa kweoksijini, ngokuqhelekileyo ibizwa ngokuba yi-oxygen concentrator. Ngenxa yoluhlu olubanzi lokusetyenziswa kwe-oksijeni kunye ne-nitrogen, i-oxygen concentrators isetyenziswa ngokubanzi kuqoqosho lwelizwe, ngakumbi kumashishini afana ne-metallurgy, ubunjineli beekhemikhali, i-petroleum kunye nokukhusela.
Olunye uhlobo lwe-oxygen concentrator lusebenzisa iimpawu ze-adsorption ze-molecular sieves. Ngemigaqo yenyama kwaye inikwe amandla yi-oyile yokufuduka ephezulu{2}icompressor yasimahla, initrogen kunye neoksijini esemoyeni zahlulwa ukufumana umoya ophezulu weoksijini. Olu hlobo lwe-oxygen concentrator luvelisa i-oksijini ngokukhawuleza kunye noxinzelelo oluphezulu, okwenza lufanelekele unyango lwe-oxygen kunye nokugcinwa kwempilo kumaqela ahlukeneyo. Isebenzisa amandla aphantsi, ixabisa iisenti ezili-18 kuphela ngeyure, nto leyo eyenza ukuba kungabizi kakhulu ukuyisebenzisa.
