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、本过违器配有永久磁铁，可滤除油液中1微米以上的铁磁性颗粒。3、具有旁通阀：冷油起动时，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基情况下，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。
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。
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，能起粗过滤作用。
6、具有目测指示和电发讯二合一发讯装置、溢流管、积污盅：
当滤芯逐步堵塞后，可在目测表上观察滤芯堵塞情况，同时还可接电发讯发讯(值为0.35MPa)。在滤芯底部设置溢流管及积污盅，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、滤芯过滤材质采用玻璃纤维，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，其过滤精度以绝对过滤精度标定过比β3、10、20≥200，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并加工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，可作系统中少量油液回入油箱过滤或向油箱少量加油之用，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。
