RFA TANK MOUNTED MINI-TYPE RETURN FILTER SERIES
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 0.35MPa, the indicator will give signals showing that the filter element should be cleaned, changed or raise the temperature. If no service is done and as the pressure reaches to 0.4MPa, the by pass 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: open the filter cover, the filter element could be changed or the oil can be injected into 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 diffuser is at bottom of the filter and can help the medium flow stably to the tank and avoid the air reentering. The filter element 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.
