Uhlobo lwefeni yesilingi ekhupha umoya omninzi ngokuqhelekileyo yiFani ePhezulu yeVolume Low Speed ​​(HVLS).HVLS abalandelizenzelwe ngokukodwa ukuhambisa umthamo omkhulu womoya ngokufanelekileyo nangempumelelo kwiindawo ezinkulu ezifana neendawo zokugcina iimpahla, izibonelelo zoshishino, ii-gymnasiums, kunye nezakhiwo zorhwebo.Abalandeli be-HVLS babonakaliswa ngamacangci abo amakhulu, anokufikelela kwii-24 ezinyaweni, kunye nesantya sabo esicothayo sokujikeleza, ngokuqhelekileyo ukusuka kwi-50 ukuya kwi-150 revolutions ngomzuzu (RPM).Oku kudityaniswa kobukhulu obukhulu kunye nesantya esicothayo kuvumela abalandeli be-HVLS ukuba bavelise ukuhamba komoya okubalulekileyo ngelixa besebenza ngokuzolileyo kwaye besebenzisa amandla amancinci.

Xa kuthelekiswa nabalandeli besilingi yemveli, eyilelwe iindawo zokuhlala ezincinci kwaye ezineedamitha ezincinci zeblade kunye nesantya esiphezulu sokujikeleza, abalandeli be-HVLS basebenza ngakumbi ekuhambiseni umoya kwiindawo ezinkulu. Basenokwenza impepho epholileyo ejikeleza umoya kuyo yonke indawo, inceda ekuphuculeni umoya, ukulawula ubushushu, nokudala indawo ehlala itofotofo kubahlali.

Ngokubanzi, ukuba ujonge ifeni yesilingi enokukhupha umoya omninzi kwindawo enkulu, iUmlandeli weHVLSinokuba lolona khetho lwakho. Aba balandeli benziwe ngobunjineli ngokukodwa ukuhambisa ukuhamba komoya okuphezulu kwaye bafanelekile kumashishini kunye nezicelo zorhwebo apho ukuhamba komoya okusebenzayo kubalulekile.
