They are used to separate solid matter from the hydraulic fluid that is flowing back into the tank. They have the following features: Filter elements based on inorganic fibre Excellent separation characteristics (b-values) over a wide differential pressure range High contamination retention capacity due to large specific filter surface area Good chemical resistance of the filter elements due to the use of epoxy resins for impregnation and bonding High bursting pressure resistance of the filter elements (e.g. during cold start) Water and water traces in the hydraulic fluid do not cause a reduction in the filtration capacity µm filter rating absolute by Bosch Rexroth AG, Industrial Hydraulics, D-978 Lohr am Main All rights reserved.

Z gn ge ZL PE ge gn Z5L -N PE Function, section These return line filters are designed to be directly mounted onto the fluid tank. They basically consist of the filter housing (), cover () with connection for backpressure indicator (), filter element (), strainer (5 ) ) as well as clogging indicator (6) (connection provided as standard). The filter elements comprise by-pass valves (7). The hydraulic fluid is fed via port A to the filter element (), where it is filtered in accordance with the relevant filter rating. The dirt particles filtered out settle in the strainer (5) ) and filter element (). The filtered hydraulic fluid is directed via port B to the tank. When the filter element () is taken out, the strainer (5) ) is pulled out as well, which prevents the settled dirt particles from entering the tank. A 6 7 ) only 5 ) B Only use filter with the clogging indicator fitted! ABZFR /8 RE 5 8/.
