Product introduction
This kind of filter can be used in hydraulic system for fine filtration. It can be installed on the cover of the tank. The filter head should be out of the tank and the filter bowl should immerse in the oil. The inlet port has threaded and flanged connections. The filter has indicator and by pass valve. When the dirt accumulates in the filter element or the temperature of the system is too low, and the oil inlet pressure reaches to 0.4Mpa, the by pas valve will open automatically to keep the hydraulic system safe. It is easy to change filter element and to inject the oil to the tank. Two oil ports at filter head which are M18X1.5, the indicator can be installed at any part and they can filter some oil which may return to the tank. The filter has fluid diffuse. The fluid diffuse is at bottom of the filter and can help the medium flow stably to the tank and avoid the air reentering. The fluid diffuse is made of glass fiber, so it has high filtration accuracy, low initial pressure loss, high dirt-holding capacity and so on. Filter radio β3,5,10,20≥200, filter efficiency n≥99.5%,and fit the ISO standard.
