Kazhinji, firita yemafuta ecompressor yemhepo ifirita yakaoma yakaiswa panopinda pombi yemafuta, nokudaro ichidzivirira tsvina kupinda mupombi. Rudzi urwu rwefirita rwuri nyore muchimiro. Rine simba shoma asi mafuta anoyerera akawanda. Chinofambisa mafuta akawanda chakasungirirwa papombi inodzosera mafuta ye hydraulic system, yekusefa zvidimbu zvesimbi, tsvina yepurasitiki, nezvimwewo. Kushandiswa kukuru kwefirita iyi ndeyekuchengetedza kuchena kwemafuta mukati metangi remafuta. Duplex firita ine chimiro chiri nyore uye iri nyore kushandisa. Kunze kwevharuvhu ye bypass, inewo mudziyo wekuyambira kana wekudzivisa kusvibiswa, kuitira kuti system ive yakachengeteka.
