液压系统中诸元件磨损产生的金属粉末及密封件的橡胶杂质等污染物，使流回油箱的油液保持清洁。
1. 设计为倒装式结构，进出油口连接尺寸符合SAE法兰标准，过滤器固定、安装连接方便，简化管路布置。
2. 设置滤芯污染发讯器，油路旁通阀，提高液压系统的可靠性。当滤芯被污染物堵塞、系统油温过低、流量脉动等因素造成进出油压差达到0.35MPa时，发讯器发出讯号指示，此时应及时更换滤芯或提高油温，若此时不能马上停机处理这些故障，设在滤芯上的旁通阀会自动开启（开启压力为0.4MPa)。
3. 滤芯采用玻璃纤维材质，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、30≥200，过滤效率n≥99.5%符合ISO标准。
