Zvinoenderana nepfungwa yekusefa, sefa yemhepo inogona kukamurwa kuita mhando yefirita, mhando yecentrifugal, mhando yekugeza mafuta uye mhando yecompound. Mafirita emhepo anowanzoshandiswa muinjini anosanganisira inertia oil bath air filter, paper dry air filter, polyurethane filter element air filter nezvimwewo. Inertia oil bath air filter yakapfuura neinertia type filter, oil bath type filter, filter type filter three filtration, mhando mbiri dzekupedzisira dzemhepo filter kunyanya kuburikidza nefilter element filter type filter. Inertia oil bath air filter ine mabhenefiti ekusapinda zvakanyanya, inogona kuchinjika kunzvimbo yekushanda ine guruva uye jecha, hupenyu hwebasa hurefu, nezvimwewo, zvaimboshandiswa mumhando dzakasiyana dzemotokari, mainjini etractor. Zvisinei, rudzi urwu rwesefa yemhepo haruna kushanda zvakanaka, huremu hwakakura, inodhura zvakanyanya uye kugadzirisa kwakashata, uye yakabviswa zvishoma nezvishoma muinjini yemotokari. Sefa yepepa yakaoma yesefa yemhepo yakagadzirwa nepepa remafirita rine microporous filter rakagadziriswa neresin. Bepa rekusefa rine maburi, rakasununguka, rakapetwa, rine simba remuchina uye rinodzivirira mvura, uye rine zvakanakira kushanda zvakanaka, chimiro chiri nyore, huremu hushoma, mutengo wakaderera, kugadzirisa zviri nyore, nezvimwewo. Ndiyo firita yemhepo yemotokari inoshandiswa zvakanyanya pari zvino. Chinhu chekusefa chefirita yemhepo chakagadzirwa nepolyurethane yakapfava, ine maburi uye ine spongy, iyo ine simba rakasimba rekuisa mvura. Iyi firita yemhepo ine zvakanakira sefirita yemhepo yakaoma yepepa, asi ine simba shoma remuchina uye inoshandiswa zvakanyanya mumainjini emotokari. Zvakashata zvefirita mbiri dzekupedzisira dzemhepo ndezvekuti hupenyu hupfupi hwebasa uye kushanda kusina kuvimbika mumamiriro ezvinhu akaoma.
