Hydraulic oil tank air breather filter element EF5-65 IntroductionThis kind of series has 8 models. It includes oil filtering and air filtering. EF series filter incorporated with oil filling is widely used in the tank of hydraulic system. Filter element is made of sintered copper powder, which is robust in const-ruction, stable in filtration and resistant to high temperature. The oil level will rise or drop during the operation of hydr-aulic system. When the oil level rises, the air will be expelled from inside. When the oil level drops, the air will be inbre-athed from outside. The breather filter can be installed directly on the tank cover to filter the inbreathed air. It also can be oil filter. When injecting the oil into tank through this breather filter, the contaminant will be filtered. Breather filter can keep the tank clean and also balance the pressure in the tank. It prolongs the service life of the components. Technical Data ModelEF1-25EF2-32EF3-40EF4-50EF5-65EF6-80EF7-100EF8-120Filter flow (l/min)91421324770110160Air flow rate (m³/min)6510517026045067510551512Oil filter area (cm2)801201802704006009421370A(mm)80100120150190220274333B(mm)4550555970808898a(mm)Φ39Φ47Φ55Φ66Φ81Φ96Φ118Φ138b(mm)Φ51Φ59Φ66.5Φ82Φ102Φ120Φ140Φ160c(mm)Φ64Φ70Φ80Φ98Φ120Φ140Φ160Φ180Screw(mm)M4X10M3X10M2X14M6X14M8X16M8X16M8X20M8X20Air filtration(mm)0.2790.2790.2790.1050.1050.1050.1050.105Oil filtration125(μm) (120Mesh/inch) (or as customer request) Filter elements are tested according to the following ISO standards:ISO 2941 Verification of collapse/burst resistanceISO 2942 Verification of fabrication integrityISO 2943 Verification of material compatibility with fluidsISO 3723 Method for end load testISO 3724 Verification of flow fatigue characteristicsISO 3968 Evaluation of pressure drop versus flow characteristicsISO 16889 Multi-pass method for evaluating filtration performance Packing & ShippingPlastic bag inside,carton box outside, or according customer special requirement.Pallet or wooden box or according customer special requirement. Our ServiceHydraulic FiltersArgo, Boll, Bosch Rexroth, CJC, Donaldson, Eaton (Internormen), Filtrec, Gardner Denver, Hydac, Hy-pro, Hifi, Hilco, Indufil, Mahle, Mp Filtri, OMT, Pall, Parker, Stauff, SF, Schroeder,Taisei Kogyo, UFI, Vickers... Compressor Air Filters & Oil Filters & SeparatorsAtlas Copco, Aerzen, ABAC, Boge, Bolaite, Compair, Ceccato, Elgi, Fusheng, Gardner Denver, Hifi, Hitachi, Ingersoll Rand, Kobelco,  Kaeser, Liutech, Mann, Quincy, Sullair, Samsung, Sotras... Compressed Precision Inline FiltersAtlas Copco, AFE, ABAC, ATS, Airflux, Beko, Boge, BEA, Ceccato, Compair, CTA, CKD, Deltech, Domnick Hunter, Donaldson (Ultrafilter), Friulair, Fusheng, FST, Gardner Denver, Hifi, Hankison, Hiross, Ingersoll Rand, Kaeser, Knocks, Kellin, KSI, Liutech,  Mikropor, MTA, Nano, Numatics, OMI, Omega, Orion, Parker, Risheng, Sotras, SMC, Sege, Shanli, Sullair, Walker, Wikerson, Zander... Vacuum Pump FiltersBusch, Leybold, Becker, Rietschle Suction Strainers, Coalescer Filters, RRR Filters, Leemin Filters, Natural gas filter, Oil Filter Purfier...  FAQQ1.
