Iyo firita isina kuchena ndeye cylindrical exter yekuvhara macuter, uye muviri wecylinger izere imba yese yekufeswa, uye muviri wecylinder une chimiro chakakosha chisimbiso munzvimbo ye discharge. Muchina unobvisa musoro wekuparadzira, pahuro uye nhamba huru yemitsetse yeiyo general yeiyo firita, uye rudzi rutsva rwekuenderera mberi kwefaira. Iyo inonyanya kuumbwa ne cylinder, chishandiso chisinga shoma, shaft shaft, dhiza, tangi rakanyura uye rakadaro. Chimiro uye kupatsanurana kwenzvimbo yebasa inoratidzwa mumufananidzo pazasi. Kana iyo firita isiri kushanda, iyo yemukati yeiyo cylinder iri pasi pecuum, kuitira kuti keke yefaira iri pamusoro pejira refaira, uye iyo filtrate uye iyo mvura yekugeza yakanyatsotsungirirwa kubva kumigumo miviri yeiyo gomo rehombodo. Uye iyo yefaira inopera nejira refaira. Iyo discharge roller yakabviswa. Muchina haufanire kuridza zvinhu uye kuchenesa jira refaira pane cylinder. Naizvozvo, basa rechisungo chisimbiso ndeyekusimbisa gomba rechisimba pachikamu cheCylinder rakafumurwa kubva mumhepo (pakati pekuti machira efaira anoendeswa kune iyo yekudzosera iyo jira rekufa) kuti udzivise vacuum kubva pakuva kutyorwa.
Chimwe chinhu chemuchero chemuchina ndechekuti tangi yekupa inotora nzvimbo yakadzika yegroove kuti uwedzere kuyamwisa fidhi nguva yekuwedzera yekugadzira mari yekugadzira. Kumhanya kumwechete, iyo yekunyora nguva yeG40-40 Type isina-kupeta bet filter ndeye 1/3 kusvika 2/3 yakakwirira kupfuura iyo yeiyo general of general filter type.
