Ubu bwoko bwa filteri bukoreshwa muri hydraulic sisitemu yo kuyungurura neza. Akayunguruzo karashobora gushungura umwanda wicyuma, umwanda wa rubber cyangwa ibindi byanduye, kandi bigakomeza isuku. Akayunguruzo gashobora gushyirwaho hejuru yumupfundikizo cyangwa gushyirwaho umuyoboro. Ifite icyerekezo na by-pass valve. Iyo umwanda urundarunda mubintu bishungura cyangwa ubushyuhe bwa sisitemu buri hasi cyane, kandi umuvuduko wamavuta winjira kuri 0.35Mpa, icyerekezo kizatanga ibimenyetso byerekana ko ikintu cyo kuyungurura kigomba gusukurwa, guhinduka cyangwa kuzamura ubushyuhe. Niba nta serivisi ikozwe kandi nkuko igitutu kigera kuri 0.4mpa, by-pass ya valve irakinguka. Akayunguruzo gakozwe mubirahuri bya fibre; bityo ifite filtration yukuri, gutakaza umuvuduko muke wambere, ubushobozi bwo gufata umwanda nibindi. Shungura radio 0 3, 5, 10, 20> 200, filterefficiency n> 99.5%, kandi ihuze na ISO.
