RFB-series filters are used in the return line of hydraulic systems. They can be installed on the top at the side or in the bottom of tanks. Every filter is equipped with a permanent magnet to remove ferrous matters in the oil. Filter element is made of non-woven fiber with high efficiency and low restriction. A diffuser is fitted in the lower part of the filter, ensuring steady oil flowing out from the tank when filter element is changed.
The differential pressure indicator will signal when the pressure drop across filter element attains 0.35Mpa and the by-pass valve opens at 0.4Mpa.
