RFB系列直回自封式磁性回油过滤器用于液压系统回油精过滤，滤除液压系统中由于元件磨损产生的金属颗粒，以及密封件磨损的橡胶杂质等污染物，使流回油箱的油液保持清洁。
性能与特点：
1、本过滤器可直接安装在油箱顶部，侧面或底部，过滤器滤头露于油箱外，筒体部分浸入油箱内，从而简化了系统管路，使系统布置较为紧凑。
2、本过滤器配有永久磁铁，可滤除油液中1微米以上的铁磁性颗粒。
3、具有旁通阀：冷油启动时，因系统液温过低，流量脉动等因素造成过滤器压差过大，主机不能工作，以及滤芯被污染物堵塞情况下，滤盖下部并联的旁通阀会自动开启，（开启压力差为0.4MPA）以保护滤芯及系统正常工作。
4、具有止回阀：过滤器置于油箱侧边和底部，在更换滤芯时，油箱内的油液不会流出。
5、设有液流扩散器，与筒体下部组成的液流扩散器能使回油平稳地流入油箱内，不易产生气泡，减少重新进入的空气，减弱已沉积污染物的骚动，且当旁通阀开启时，能起粗过滤的作用。
6、具有目测指示和电发讯二合一发讯器装置、溢流管、集污蛊。当滤芯逐步堵塞后，可在目测表上观察滤芯堵塞情况，同时还可以接电发讯器。在滤芯底部设置溢流管及集污蛊，更换滤芯时可随同一起带出，从而避免了污染物重新掉入油箱内的现象。
7、滤芯采用玻璃纤维过滤材质具有过滤精度高、通油能力大、原始压力损失小、纳污量大等优点。其过滤精度以过滤精度标定，过滤比β3、5、10、20≥200，过滤效率n≥99.5%，符合ISO标准。
8、具有安装连接及更换滤芯方便的特点：进油口为法兰连接，对于滤头与油箱安装法兰，用户可按图表中尺寸在油箱板上设计加工6只法兰螺孔即可。旋开过滤器顶盖可更换滤芯或向油箱内加油。
9、具有附带回油孔：在过滤器滤头侧面与顶部设有两个小回油孔，可作系统中少了油液回入油箱过滤或向油箱内少量加油之用，过滤器装在油箱侧面或底部时，旋开小孔盖又可放除过滤器内含有污染杂物的油液，从而延长滤芯使用寿命，又有利于油液的净化。
