RFB Return-Line Filters
RFB Return-Line Filters are designed as tank top filters. They are mounted directly on the tank top and if 100% of the system oil is filtered they provide the optimum removal of contaminant from the system. This provides the pump with clean oil thus reducing contaminant generated wear. Because of it’s low weight and compact design, they are ideally suited for mobile hydraulic applications. 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.
