ISO Hydraulic Tank Return Filter RFA-1000*3F-C RFA-800*3F-Y

















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 indior 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 indior 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
indior 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.
