Fan muchina wakashongedzerwa nemablades maviri kana anopfuura ekusundidzira kuyerera kwemhepo. Iwo mablades anoshandura iyo inotenderera mechanical simba rinoshandiswa pashaft mukuwedzera kwekumanikidza kusundira gasi kuyerera. Iyi shanduko inoperekedzwa nekufamba kwemvura.
Iyo yekuedzwa mwero weAmerican Society of Mechanical Engineers (ASME) inomisa feni kune gasi density yekuwedzera isingapfuure 7% kana ichipfuura nepamhepo inopinza kuenda kumhepo yekubuda, iyo inenge 7620 Pa (30 inches yemvura column) pasi pemamiriro ezvinhu. Kana dzvinyiriro yaro inopfuura 7620Pa (30 inches yembiru yemvura), ndeye "compressor" kana "blower" ·
Kudzvinyirirwa kwemafeni anoshandiswa pakudziya, kufefetedza uye kufefetedza mhepo, kunyangwe mumasisitimu ekumhanya-mhanya uye nepamusoro-soro, kazhinji haipfuure 2500-3000Pa (10-12 inches yembiru yemvura) ·
Iyo fan ine zvikamu zvitatu zvikuru: impeller (dzimwe nguva inonzi turbine kana rotor), midziyo yekutyaira uye shell.
Kuti unyatso kufanotaura kushanda kwefani, mugadziri anofanira kuziva:
(a) Maitiro ekuongorora uye kuyedza turbine yemhepo;
(b) Mhedzisiro yemhepo duct system pane fan fan.
Mhando dzakasiyana dzevateveri, kunyangwe iwo mafani emhando imwechete anogadzirwa nevagadziri vakasiyana, vane kudyidzana kwakasiyana nehurongwa
