过滤精度是指过滤器对不同尺寸颗粒污染物的滤除能力，常用绝对过滤精度，过滤比和过滤效率等指标来评定，过滤精度分为粗（d≥0.1mm）、普通（d≥0.01mm）、精（d≥0.005mm）、和特精（d≥0.001mm）四个等级。

2．压降特性

液压系统中的过滤器对油液来说是一种液阻，因而油液经过时必然要产生压降。一般来说，在滤芯尺寸和油液流量一定的情况下，滤芯的过滤精度越高，则其压降越大，在流量一定的情况下，滤芯的有效过滤面积越大，或油液的粘度越小，则压降越小。0330R003BN/HC 0330R005BN/HC 0330R010BN/HC 0330R020BN/HC 0330R003BN3HC 0330R005BN3HC 0330R010BN3HC 0330R020BN3HC 0330R003BN4HC 0330R005BN4HC 0330R010BN4HC 0330R020BN4HC 0330R020P     0330R020W
