3 Return line filters Series Description The filters series are suitable for application on the return line of hydraulic circuits with rated flow up to 5 l/min. They are designed to be installed on the tank top, semi immersed in the oil tank. ll series are equipped with y-pass valve and an air breather available with filtration rating of or 4 microns. It is designed into the head of the filter for reservoir ventilation. visual or electrical indicator is available as an option. The filters series are specifically designed for use on small power units for industrial or mobile applications. Technical data filter elements /: paper treated with resin, filtration rating and 5 microns, ßx /G/H: inorganic fiber, filtration rating 6, and 5 microns, ßx M/L: stainless steel wire mesh (ISI 34), filtration rating 5 and 6 microns /E: brass wire mesh, filtration rating 9 and 5 microns End cap in galvanized steel Support tube in galvanized steel Support mesh in galvanized steel with epoxy coating Technical data complete filter Filter head in aluminium alloy ap and bowl in fiber glass reinforced ylon Max working pressure = bar Differential collapse pressure filter elements = 5 bar y-pass valve set at,5 bar ± % Working temperature from - up to +95 onnections: SP PT SE threaded ports from / up to Filter elements are manufactured in accordance with the following ISO standards: ISO 457 Filtration performance valuated with Multi-pass test ISO 94 Verification of collapse/burst resistance ISO 94 Verification of fabrication integrity and determination of the first bubble point ISO 943 ompatibility of materials with fluids (type HH, HM, HR, HV, HG according with ISO 6743/4) ISO 373 Method for the end load test ISO 374 Verification of flow fatigue characteristics ISO 3968 Evaluation of pressure drop versus flow characteristics
