Jenareta set air sefa: Chishandiso chekupinza mhepo chinonyanya kusefa zvimedu uye tsvina mumhepo inoyamwa nepiston jenareta yakaiswa kana ichishanda. Inoumbwa nesefa element uye shell. Izvo zvinonyanya kudiwa zvefirita yemhepo ndeyekusefa kwepamusoro, kushomeka kuyerera kwekudzivirira, uye kuenderera kushandiswa kwenguva yakareba pasina kugadzirisa. Apo jenereta yakagadzika iri kushanda, kana mhepo inoputirwa ine guruva uye zvimwe zvakasvibiswa, inowedzera kupfeka kwezvikamu, saka firiji yemhepo inofanira kuiswa.

Kusefa kwemhepo kune matatu modes: inertia, filtration uye oiri yekugezesa. Inertia: nokuti kuwanda kwezvimedu uye kusvibiswa kwakakwirira kudarika kwemhepo, apo zvidimbu uye tsvina zvinotenderera kana kuita shanduko dzakapinza nemhepo, simba re centrifugal inertial rinogona kuparadzanisa tsvina kubva kumhepo yegesi.

Rudzi rwesefa: tungamira mhepo kuyerera kuburikidza nesimbi sefa sikirini kana sefa bepa, etc. Kuvhara zvimedu uye tsvina uye kunamatira kune sefa chinhu. Oiri yekugezesa mhando: Pane pani yemafuta pazasi pesefa yemhepo, kuyerera kwemhepo kunoshandiswa kukanganisa mafuta, zvimedu netsvina zvinopatsanurwa uye zvakanamira mumafuta, uye madonhwe emafuta akashungurudzika anoyerera nepakati pesefa chinhu chine kuyerera kwemhepo uye kunamatira pane sefa element. Iyo air flow filter element inogona kuwedzera adsorb tsvina, kuitira kuti uwane chinangwa chekusefa.

Iyo yekutsiva kutenderera kwemhepo sefa yejenareta seti: iyo yakajairika jenareta seti inotsiviwa yega yega maawa 500 ekushanda; seti yejenareta inotsiviwa ega ega maawa 300 kana mwedzi mitanhatu. Kana jenareta seti ichiwanzochengetedzwa, inogona kubviswa uye kuvhuvhuta nepfuti yemhepo, kana kutsiva kutenderera kunogona kuwedzerwa nemaawa mazana maviri kana mwedzi mitatu.

Zvinodiwa zvekusefa zvemafirita: mafirita chaiwo anodiwa, asi anogona kunge ari mabhurendi makuru, asi zvigadzirwa zvemanyepo uye zvakaderera hazvifanirwe kushandiswa.
