This kind of filter can be installed directly under electric magnetic directional valve in order to filter contamination. It is especially used in automatic and servo system.
It has contamination indicator. When the filter element is blocked by contamination and the pressure reaches to 0.5Mpa, the indicator will give signals showing the element should be changed.
This kind of filter is made of glass fiber. Compare to other filters, the filter is designed into small size and ithas high filtration accuracy, low initial pressure, and high dirt-holding capacity. Filter ratio。3,5,10,20>200,filter efficiency n > 99.5%, and fit the ISO standard.
