Mfundo yogwira ntchito ndi yosavuta: madziwo, omwe amanyamula tinthu tating'onoting'ono, timalowa mu cyclone kwenikweni, mizere yolowera mkati ndikupanga gawo la centrifugal mu maluwa aulere. Tinthu tating'onoting'ono timasunthira kudzera kunja kwa madzi ozungulira pa chimphepo chozungulira, ndikutuluka mu spigot ndi kachigawo ka madzi. Chifukwa cha gawo lopanda pake la spigot, voctox yamkati, imazungulira mbali yomweyo pomwe vortex wakunja koma ikukhazikitsidwa ndikusiya chimphepo chamkuntho, chimanyamula tinthu tambiri tambiri ndi icho. Ngati ma spigot mphamvu imapitilira, malo omwe ali pachimake amatsekedwa ndipo kutulutsa kwa spigot kumasintha kuchokera ku maambulera kapena chingwe 'komanso kutayika kwa zinthu zosefukira.
Dongosolo la gawo la cylindrical ndi tanthauzo lalikulu lomwe likukhudza kukula kwa tinthu yomwe ikhoza kulekanitsidwa, ngakhale diamenti ya ma exelelet zitha kusinthidwa popanda kusintha kuti kupatulizedwe. Pomwe ogwira ntchito amayeserera ndi ma cuclonlos ochepa ngati 5 mm, ma c -5 m, ndi kuchuluka kwa ma 1-5- 300 μm, kuchuluka kwa tinthu tambiri. Kutumiza kukakamiza komwe kumayambira 10 bar kwa ma diameter ang'onoang'ono mpaka 0,5 bar kwa mayunitsi akulu.
