(1)PALL濾芯要裝在泵的吸油口處：
泵的吸油路上一般都安裝有表面型濾油器，目的是濾去較大的雜質微粒以保護液壓泵，此外濾油器的過濾能力應為泵流量的兩倍以上，壓力損失小于0.02MPa。
(2)pall濾芯安裝在泵的出口油路上：
此處安裝濾油器的目的是用來濾除可能侵入閥類等元件的污染物。其過濾精度應為10～15μm，且能承受油路上的工作壓力和沖擊壓力，壓力降應小于0.35MPa。同時應安裝
安全閥以防濾油器堵塞。
(3)pall濾芯安裝在系統的回油路上：這種安裝起間接過濾作用。一般與過濾器并連安裝一背壓閥，當過濾器堵塞達到一定壓力值時，背壓閥打開。
(4)pall濾芯安裝在系統分支油路上。
(5)pall濾芯單獨過濾系統：大型液壓系統可專設一液壓泵和濾油器組成獨立過濾回路。
pall濾芯液壓系統中除了整個系統所需的濾油器外，還常常在一些重要元件(如伺服閥、精密節流閥等)的前面單獨安裝一個專用的精濾油器來確保它們的正常工作。
