在液壓系統中，用于濾除工作介質中的固體顆粒及膠狀物質，有效控制工作介質的污染度。本系列替代進口賀德克濾芯是對國外進口設備用濾芯國產化后的替代產品，可以分別替代PALL、HYDAC、賀德克、MANN，德國emg等公司的產品。替代進口濾芯性能指標：過濾精度：1 ～ 100μm工作壓力（MAX）：21MPa工作介質：一般液壓、磷酸脂液壓油、乳化液、水-乙二醇工作溫度：-30℃～+110℃ 
（二）、賀德克濾芯emg濾芯 
1、可使系統快速達到并維持期望的油液清潔水平。 
2、可延長油液的使用壽命。 
3、 減少軸承磨損。 
賀德克濾芯 
1.產品概括 
該系列高壓油濾芯是安裝在液壓系統的油路中用于清除液壓系統中各元件磨損的金屬粉末及其它機械雜質使油路保持清潔，延長液壓系統壽命。 低壓系列濾芯還設有旁通閥，當濾芯未及時更換時，旁通閥能自動打開，保證系統正常運轉。 該系列產品是美國，德國，英國、意大利等國同類產品的替代品。
