I-oxygen concentrator ingumshini okhiqiza umoya-mpilo. Isimiso saso sisekelwe kubuchwepheshe bokuhlukanisa umoya. Okokuqala, umoya ucindezelwa ukuze ube nokuminyana okuphezulu. Bese, kusetshenziswa izindawo ezihlukene zokujiya zezingxenye zomoya, ukuhlukaniswa kwegesi{3}}kuvela ezingeni lokushisa elithile. Ekugcineni, i-distillation ihlukanisa umoya ube umoya-mpilo ne-nitrogen. Ngenxa yokuthi ngokuyinhloko isetshenziselwa ukukhiqiza umoya-mpilo, ngokuvamile ibizwa ngokuthi i-oxygen concentrator. Ngenxa yobuningi bokusetshenziswa kwe-oksijeni ne-nitrogen, izigxili ze-oxygen zisetshenziswa kakhulu emnothweni wezwe, ikakhulukazi ezimbonini ezifana ne-metallurgy, ubunjiniyela bamakhemikhali, i-petroleum, ne-defense.
Olunye uhlobo lwe-oxygen concentrator lusebenzisa izakhiwo ze-adsorption zama-sieve amangqamuzana. Ngezimiso zomzimba namandla{1}}kawoyela oguquguqukayo aphezulu{2}ophezulu{2}}i-compressor yamahhala, i-nitrogen nomoya-mpilo osemoyeni kuyahlukaniswa ukuze kutholwe ukugcwala okuphezulu komoyampilo. Lolu hlobo lwe-oxygen concentrator lukhiqiza umoya-mpilo ngokushesha futhi ekugxiliseni okuphezulu, okwenza lufanele ukwelashwa komoya-mpilo kanye nokugcinwa kwezempilo kwamaqembu ahlukahlukene. Isebenzisa amandla amancane, ibiza amasenti angu-18 kuphela ngehora, okwenza ingabizi ukuyisebenzisa.
