Nubwo umwimereregupakiray'amashanyarazi deaerator ikoresha ibice umunani byo gupakira, biragoye kugera kuri leta nziza ya firime yamazi kuko amwe muri yo yaravunitse, aragoramye, kandi arimurwa. Amazi yatewe nyuma yo gutera spray akora amazi atemba kurukuta rwa deaerator. Nubwo yongeye kugabanwa ku isahani y’amazi yongeye kunyuzwa mu kigega cyo gukusanya amazi, biragoye kugera ku gishushanyo mbonera cyo gukwirakwiza amazi mu gice cya spray ku bipfunyika bitewe n’imiterere yacyo (hafunguwe umwobo urenga 4000 Φ8 kuri disiki nini ifite diameter ya 1300mm). Bitewe nuko firime yamazi itameze neza, gutera kumupaki ntago bingana, kubwibyo amazi yatewe hamwe nicyuka cya kabiri kidashobora gukora neza uburyo bwo kwimura no kwimura abantu, cyane cyane uburyo bwo kwimura abantu.
Ibice umunani gusa byo gupakira ntibishobora kuzuza ibisabwa, nimwe mumpamvu zituma deaerator agira ubujyakuzimu bwa deoxygene. Kubera iyo mpamvu, hafashwe ingamba zikurikira:
a) Simbuza igipimo cyo gupakira cyaguye, ni kigufi, kigoramye, cyangwa cyacitse;
b) Ongeramo izindi nzego ebyiri zo gupakira mumwanya muto;
c) Uzuza hejuru yumurongo wamazi hamwe nicyuma cyuma kitagira umuyonga kugirango umenye neza ibitonyanga byamazi byatewe kumupaki.
