This filter is used to finely filtrate return oil from the hydraulic system and filtrate metal particles generated due to wear of the hydraulic system elements, seal rubber impurities and other contaminants, so as to keep oil from the oil return tank clean. 1. This filter can be directly mounted on the tank cover plate, or can be mounted by using pipes. 2. This filter is provided with a filter contamination and blockage indicator and bypass valve so as to improve the reliability of alternative hydraulic flow. When the filter is blocked by contaminants or the fluid temperature of the system is too low and the oil inlet pressure is 0.35MPa under the influences of flow fluctuation and other factors, the indicator sends a signal. At this time, you shall immediately replace the filter or raise the temperature . If you cannot stop it for troubleshooting,the bypass valve on the filter will automatically open (pressure: 04Mpa). 3. The filter is made of glass fiber, and has advantages such as high filtration precision, high oil flow capacity, low initial pressure loss and high dirt holding capacity, and its filtration precision is calibrated based on the absolute filtration precision. The filtration efficiency n reaches 99.5% or higher when the filtration ratio β3, 5, 10, 20 is equal to or larger than 200, up to ISO standards.5% or higher when the filtration ratio β3, 5, 10, 20 is equal to or larger than 200, up to ISO standards.5% or higher when the filtration ratio β3, 5, 10, 20 is equal to or larger than 200, up to ISO standards.
