RFA Return-Line Filters
RFA Return-Line Filters are a one piece design and can be used as a tank top or an in-line filter. They are mounted in the Return-Line and if 100% of the system oil is filtered, provide the optimum removal of contaminant for the systems. This provides the pump with clean oil, thus reducing contaminant generated wear. A high efficiency of contaminant removal is assured. The high dirt-hold capacity ensures a long service life and as a result reduced maintenance costs. Furthermore, this housing also offers the possibility of pipeline mounting.
