Chinhu chekusefa ndicho chikamu chakakosha chemuchina wekuparadzanisa mafuta emhepo. Kazhinji, muchina wekuparadzanisa mafuta emhepo une hunyanzvi hwepamusoro unowanikwa nechinhu chekusefa chine hupenyu hwekushanda hunosvika zviuru zvemaawa. Saka, rudzi urwu rwemuchina wekuparadzanisa runogona kuve nechokwadi chekuti compressor yemhepo inoshanda zvakanaka. Mhepo yakamanikidzwa inogona kunge iine madonhwe akawanda emafuta madiki ane dhayamita iri pasi pe1um. Madonhwe ese emafuta aya achasefa nechinhu chekusefa chegirazi fiber. Pasi pesimba rekupararira kwechinhu chekusefa, achakurumidza kuunganidzwa kuita makuru. Madonhwe makuru emafuta achaunganidzwa pasi pasi pebasa regiravhiti. Pakupedzisira, achapinda muchimiro chekuzora kuburikidza nepombi yekudzosa mafuta. Nekuda kweizvozvo, mhepo yakamanikidzwa inoburitswa mucompressor yemhepo yakachena, uye haina mafuta.
Asi kusiyana nemadonhwe emafuta madiki, zvidimbu zvakasimba zviri mumhepo yakamanikidzwa zvinosara muchikamu chekusefa, zvichikonzera kuwedzera kwedhigirii. Kana differential pressure iri 0.08 kusvika 0.1Mpa, unofanira kutsiva filter element. Zvikasadaro, mari yekushandisa air compressor ichawedzera zvakanyanya.
