Ubwoko bwumufana wa gisenge ushyira hanze umwuka mwinshi mubisanzwe umuyaga mwinshi wo hejuru (HVLS).Abafana ba HVLSbyashizweho byumwihariko kugirango bimure umwuka mwinshi neza kandi neza ahantu hanini nko mububiko, ibikoresho byinganda, siporo ngororamubiri, hamwe nubucuruzi bwubucuruzi.Abafana ba HVLS barangwa nibyuma binini bya diameter, bishobora kumara metero 24, kandi umuvuduko wabo wo kuzenguruka buhoro, mubisanzwe kuva kuri 50 kugeza kuri 150 kumunota (RPM).Uku guhuza ubunini bunini n'umuvuduko gahoro bituma abafana ba HVLS kubyara umwuka wingenzi mugihe ukora bucece kandi ukoresha ingufu nkeya.

Ugereranije nabafana ba kaburimbo gakondo, bagenewe ahantu hatuwe hatuwe kandi mubisanzwe bafite diametero ntoya hamwe numuvuduko mwinshi wo kuzunguruka, abafana ba HVLS nibyiza cyane mukwimura ikirere ahantu hanini. Bashobora gukora umuyaga woroheje uzenguruka ikirere ahantu hose, bigafasha kunoza umwuka, kugenzura ubushyuhe, no gushyiraho ahantu heza kubatuye.

Muri rusange, niba ushaka umuyaga wa gisenge ushobora gushyira umwuka mwinshi mumwanya munini, anUmufana wa HVLSbirashoboka. Aba bafana barakozwe muburyo bwihariye kugirango batange umusaruro mwinshi wo mu kirere kandi nibyiza mubikorwa byinganda nubucuruzi aho kugenda neza kwingirakamaro.
