過濾精度是指過濾器對不同尺寸顆粒污染物的濾除能力，常用絕對過濾精度，過濾比和過濾效率等指標來評定，過濾精度分為粗（d≥0.1mm）、普通（d≥0.01mm）、精（d≥0.005mm）、和特精（d≥0.001mm）四個等級。

2．壓降特性

液壓系統中的過濾器對油液來說是一種液阻，因而油液經過時必然要產生壓降。一般來說，在濾芯尺寸和油液流量一定的情況下，濾芯的過濾精度越高，則其壓降越大，在流量一定的情況下，濾芯的有效過濾面積越大，或油液的粘度越小，則壓降越小。0330R003BN/HC 0330R005BN/HC 0330R010BN/HC 0330R020BN/HC 0330R003BN3HC 0330R005BN3HC 0330R010BN3HC 0330R020BN3HC 0330R003BN4HC 0330R005BN4HC 0330R010BN4HC 0330R020BN4HC 0330R020P     0330R020W
