SRFA Duplex Tank Mounted Mini-type Return Filter Series SRFA-40 SRFA-63 SRFA-100 SRFA-160 SRFA-250 SRFA-400 SRFA-630 SRFA-800 INTRODUCTION  The SRFA series filter is compose of two signal bowl filters and a 2-position 3-way directional valve, by-pass valve, indicator and diffuser. It is simple in structure and easy to use. It is mounted on tank top, there is by-pass valve and contamination indicator in it, for protecting the hydraulic system safety.  The feature of this filter allows continuous operation even during replacing element which is clogged by contaminant. When the filter element is clogged by contaminant that results in the temperature reaching to 0.35MPa, the indicator will give signals. At this time, turn the directional valve in order to make the other filter work then change the element.  If the element can not be changed in time that make the pressure reaches to 0.4MPa, then theBy-pass valve will open to keep the system safety.  The diffuse is installed under the filter bowl, which makes the medium flow stably into the tank.  The filter element is with high filtration accuracy, low initial pressure loss and high dirt holding capacity. Filter ratio β 3. 5. 10, 20 ≥ 200 filtration efficiency n ≥ 99.5%, and fit the ISO standard. Technical Data ModelFlow RateFiltr.(um)DiaPress.Pressure loss (MPa)IndicatorConnectModel of element(L/Min)(mm)(MPa)InitialMax(V)(A)SRFA-25X*L-C/Y251201.6≤0.080.35122.5ThreadSFAX-25X*SRFA-40X*L-C/Y40320242SFAX-40X*SRFA-63X*L-C/Y63532631.5SFAX-63X*SRFA-100X*L-C/Y10010322200.25SFAX-100X*SRFA-160X*F-C/Y1602050FlangeSFAX-160X*SRFA-250X*F-C/Y2503050SFAX-250X*SRFA-400X*F-C/Y40065SFAX-400X*SRFA-630X*F-C/Y63090SFAX-630X*SRFA-800X*F-C/Y80090SFAX-800X*SRFA-1000X*F-C/Y100090SFAX-1000X* 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.
