Fan ke mochini o nang le li-blade tse peli kapa ho feta ho sutumelletsa moea. Li-blades li tla fetola matla a mechine a potolohang a sebelisoang ka shaft ho eketsa khatello ea ho sutumetsa phallo ea khase. Phetoho ena e tsamaisana le motsamao oa mokelikeli.
Tekanyetso ea teko ea American Society of Mechanical Engineers (ASME) e beha moeli oa fan ho keketseho ea khase e sa feteng 7% ha e feta ka har'a moea o kenang sebakeng sa moea, se ka bang 7620 Pa (30 inches ea kholomo ea metsi) tlas'a maemo a tloaelehileng. Haeba khatello ea eona e le kholo ho feta 7620Pa (30 inches of water column), ke ea "compressor" kapa "blower"·
Khatello ea li-fan tse sebelisetsoang ho futhumatsa, ho kenya moea le moea, esita le tsamaisong ea lebelo le phahameng le khatello e phahameng, hangata ha e fete 2500-3000Pa (10-12 inches of water column)·
Fene e na le likarolo tse tharo tse kholo: impeller (eo ka linako tse ling e bitsoang turbine kapa rotor), lisebelisoa tsa ho khanna le khetla.
E le ho bolela esale pele ka nepo ts'ebetso ea fan, moqapi o lokela ho tseba:
(a) Mokhoa oa ho lekola le ho lekola mochini oa moea;
(b) Tšusumetso ea tsamaiso ea moea ea ho tsamaisa moea tšebetsong ea fan.
Mefuta e fapaneng ea balateli, esita le mofuta o tšoanang oa balateli ba hlahisoang ke bahlahisi ba fapaneng, ba na le likamano tse fapaneng le sistimi
