3R濾油機濾芯，精密過濾器經過三層過濾， 層是濾芯的表面層，濾去可見的大粒子；第二層是上層，濾去較小的粒子；第三層是加壓層，濾去微米級的粒子。所以華日自主生產3r精密過濾器能保證油液達到NAS7-8級，甚至達到NAS5~6級。金碩自主生產3r精密過濾器設備輕小，技術安全性高，體積小，設備安裝簡單、而且成本相對低。維護容易，只需定期更換濾芯3R精密濾油機：        CS-SS305-2RBQ,CS-SS102-1RB,CS-SS103-2RB,CS-SS103-3RB,CS-SS304-2RB,CS-SS304-1RB,CS-SS305-1RB,CS-SS305-2RB,CS-SS103PF-10-20-1RB,CS-SS104PF-10-20-1RB,CS-SS104PF-10-20-2RB,CS-SS104PF-10-20-3RB,CS-SS312PF-20-20-1RB,CS-SS312PF-20-20-2RB,CS-SS103-4PF10-20-1RB,CS-SS103-4PF10-20-2RB,CS-SS305-12PF20-20-1RB
