(1)頗爾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)頗爾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)頗爾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)頗爾濾芯安裝在系統分支油路上。   
  (5)頗爾濾芯單獨過濾系統：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。頗爾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。  PALL頗爾濾芯PALLHC572FEC9H，HCS630KUN9H，HCS630KUP9H，HCS630KUS9H，HCS630KUT9H，HC0101FKN36H，HC0101FKP36H，HC2216FKP6Z，HC2216FKS6H，HC2216FKS6Z，HC2216FKT6H，HC2216FKT6Z，HC2217FKN4H，HC2217FKN4Z，HC0101FKS36H，HC0101FKT36H，HC2206FDN3H，HC2206FDP3H，HC2206FDS3H，HC2206FDT3H，HC2206FDN6H，HC2206FDP6H，HC2206FDS6H，HC2206FDT6H，HC2207FDN3H，HC2207FDP3H，HC2207FDS3H，HC2207FDT3H，HC2207FDN6H，HC2207FDP6H，HC2207FDS6H，HC2207FDT6H，HC2208FKN4Z，HC2208FKN6H，HC2208FKP6Z，HC2208FKP4H，HC2208FKP4Z，HC2208FKS6H，HC2208FKS6Z，HC2208FKS4H，HC2208FKT4Z，HC2208FKT6H，HC2208FKT6Z，HC2216FKN4H，HC2216FKN4Z，HC2216FKP4H，HC2216FKP4Z，HC2216FKS4H，HC2216FKS4Z，HC2216FKT4H，HC2216FKT4Z，HC2216FKN6H，HC2216FKN6Z，HC2216FKP6H，HC2253FDN6H，HC2253FDP6H，HC2217FKP4H，HC2217FKP4Z，HC2218FKN4H，HC2218FKN4ZHC2218FKP4H，HC2218FKP4Z，HC2218FKN6H，HC2218FKN6Z，HC2218FKP6H，HC2218FKP6Z，HC2225FDN6H，HC2225FDP6H，HC2225FDN13H，HC2225FDP13H，HC2233FDN6H，HC2233FDP6H，HC2233FDN13H，HC2233FDP13H，HC2235FDN6H，HC2235FDP6H，HC2235FDN13H，HC2235FDP13H，HC2236FDN6H，HC2236FDP6HHC2236FDN13H，HC2236FDP13H，HC2237FDN6H，HC2237FDP6H，HC2237FDN13H，HC2237FDP13H，HC2238FDN6H，HC2238FDP6H，HC2238FDP13H，HC2238FDP6H，HC2252FDN6H，HC2252FDP6H，HC2252FDP13H，HC2252FDP6H，HC2253N6H，HC2253P6H，HC6500FKN26H，HC6500FKP26H，HC2257FDN6H，HC2257FDP6HHC2257FDP13H，HC2257FDP6H，HC2285FDN6H，HC2285FDP6H，HC2285FDN13H，HC2285FDP13H，HC2293FDN6H，HC2293FDP6H，HC2293FDN13H，HC2293FDP13H，HC2295FDN6H，HC2295FDP6H，HC2295FDN13H，HC2295FDP13H，HC2544FKN9H，HC2544FKP9H，HC2544FKN19H，HC2544FKP19H，HC2618FDN6H，HC2618FDP6HHC2618FDN13H，HC2618FDP13H，HC6200FKN4H，HC6200FKP4H，HC6200FKN8H，HC6200FKP8H，HC6400FKN8H，HC6400FKP8H，HC6400FKN13H，HC6400FKP13H，HC6400FKN16H，HC6400FKP16H，HC6400FKN26H，HC6400FKP26H，HC6500FKN13H，HC6500FKP13H，HC6500FKN16H
