Abalandeli beVolume High Speed ​​​​Low Speed ​​(HVLS).ziphawulwa ngobubanzi bazo obukhulu kunye nesantya esicothayo sokujikeleza, esibahlula kubalandeli besilingi bemveli. Ngelixa isantya esichanekileyo sokujikeleza sinokwahluka ngokuxhomekeke kwimodeli ethile kunye nomenzi, abalandeli be-HVLS ngokuqhelekileyo basebenza ngesantya esisuka kwi-50 ukuya kwi-150 revolutions ngomzuzu (RPM).

Igama elithi "isantya esiphantsi" kwiifeni ze-HVLS libhekisa kwisantya esicothayo sokujikeleza xa kuthelekiswa nabalandeli bemveli, abasebenza ngesantya esiphezulu kakhulu. Lo msebenzi unesantya esisezantsi uvumela abalandeli be-HVLS ukuba bahambise ngokufanelekileyo umthamo omkhulu womoya ngelixa besenza ingxolo encinci kwaye besebenzisa amandla amancinci.

Isantya sokujikeleza somqhubi we-HVLS siyilwe ngononophelo ukwenzela ukuba kuphuculwe ukuhamba komoya kunye nokujikeleza kwiindawo ezinkulu ezifana neendawo zokugcina iimpahla, iindawo zokuvelisa, iindawo zokuzilolonga, kunye nezakhiwo zorhwebo. Ngokusebenza ngesantya esiphantsi kunye nomoya oshukumayo ngendlela ethambileyo, engaguqukiyo,HVLS abalandeliinokudala indawo ekhululekile kunye nomoya ococekileyo kubahlali ngelixa unciphisa ukusetyenziswa kwamandla kunye neendleko zokusebenza.
