Ifeni ngumatshini oxhotyiswe ngeencakuba ezimbini nangaphezulu ukutyhala ukuhamba komoya. Iiblades ziya kuguqula amandla omatshini ajikelezayo asetyenziswe kwi-shaft ekunyukeni koxinzelelo lokutyhala ukuhamba kwegesi. Olu tshintsho luhamba kunye nokuhamba kwamanzi.
Umgangatho wovavanyo we-American Society of Mechanical Engineers (ASME) unciphisa umtshini ekunyukeni koxinzelelo lwegesi olungekho ngaphezu kwe-7% xa udlula kwi-inlet yomoya kwi-outlet yomoya, malunga ne-7620 Pa (30 intshi yekholomu yamanzi) phantsi kweemeko ezisemgangathweni. Ukuba uxinzelelo lwayo lungaphezulu kwe-7620Pa (i-intshi ezingama-30 zoluhlu lwamanzi), yeye "compressor" okanye "blower"·
Uxinzelelo lweefeni ezisetyenziselwa ukufudumeza, ukungena komoya kunye ne-air conditioning, nakwi-high-speed and high-pressure systems, ngokuqhelekileyo ayidluli kwi-2500-3000Pa (10-12 intshi yekholomu yamanzi) ·
I-fan iqulethe izinto ezintathu eziphambili: i-impeller (ngamanye amaxesha ibizwa ngokuba yi-turbine okanye i-rotor), izixhobo zokuqhuba kunye neqokobhe.
Ukuze uqikelele ngokuchanekileyo ukusebenza kwefeni, umyili kufuneka azi:
(a) Indlela yokuvavanya nokuvavanya i-injini yomoya;
(b) Impembelelo yesixokelelwano sombhobho womoya ekusebenzeni kwefeni.
Iindidi ezahlukeneyo zabalandeli, kunye nohlobo olufanayo lwabalandeli abaveliswa ngabavelisi abahlukeneyo, banobudlelwane obuhlukeneyo kunye nenkqubo
