Abalandeli be-High Volume Low Speed ​​(HVLS).zibonakala ubukhulu bazo obukhulu kanye nesivinini sokujikeleza esinensayo, esibahlukanisa nabalandeli bendabuko be-ceiling. Nakuba isivinini esiqondile sokuzungeza singahluka kuye ngemodeli ethile nomkhiqizi, abalandeli be-HVLS ngokuvamile basebenza ngesivinini esisuka ku-50 kuya ku-150 revolution ngomzuzu (RPM).

Igama elithi “ijubane eliphansi” kumafeni we-HVLS lisho isivinini sabo esinensayo sokuzungeza uma kuqhathaniswa nabalandeli bendabuko, abavame ukusebenza ngesivinini esiphezulu kakhulu. Lokhu kusebenza kwesivinini esiphansi kuvumela abalandeli be-HVLS ukuthi bahambise kahle amavolumu amakhulu omoya kuyilapho kukhiqiza umsindo omncane futhi kudla amandla amancane.

Ijubane lokujikeleza lefeni ye-HVLS yakhelwe ngokucophelela ukuze kuthuthukiswe ukugeleza komoya kanye nokuzungeza ezindaweni ezinkulu ezifana nezindawo zokugcina izimpahla, izindawo zokukhiqiza, izindawo zokuvivinya umzimba, nezakhiwo zentengiso. Ngokusebenza ngesivinini esiphansi kanye nomoya onyakazayo ngendlela emnene, engaguquguquki,Abalandeli be-HVLSingakha indawo enethezekile futhi enomoya omuhle kubahlali ngenkathi inciphisa ukusetshenziswa kwamandla kanye nezindleko zokusebenza.
