Emsebenzini omkhulu, ukugcina ukuhamba komoya okuhle kanye nokusebenza kahle kwamandla kubalulekile kokubili ukuze kube nenduduzo kanye nokusebenza kahle. Amafeni ophahla lwezimboni e-HVLS avele njengesixazululo esibalulekile kulezi zinselele, enikeza izinzuzo ezibalulekile ezithuthukisa indawo yokusebenza.

Enye yezinzuzo eziyinhloko zokufaka ifeni yophahla lwezimboni i-Apogee HVLS ukugeleza komoya okuthuthukisiwe. Indawo yokusebenzela ivame ukuba nophahla oluphezulu nezindawo ezinkulu zaphansi, okungaholela emigodini yomoya engami. Ifeni ye-Apogee HVLS isiza ukusabalalisa umoya ngokulinganayo kuyo yonke indawo, umsindo wayo ≤38db, uthule kakhulu. Amafeni e-Apogee HVLS anciphisa izindawo ezishisayo futhi aqinisekise indawo yokusebenza ekhululekile. Lokhu kubaluleke kakhulu ezimbonini lapho abasebenzi behileleke khona emisebenzini enzima ngokomzimba.
