As we all know, the line filter is composed of ZU-H pressure line filter and ZU-A return line filter. It can be seen from the model, but they are fundamentally different. The following we will give you a brief introduction to the difference between the two.
First: different meanings - ZU-H is a pressure line filter
ZU-A belongs to the return line filter
Second: different installation places - ZU-H filter installed on the hydraulic system pressure line
ZU-A is installed on the return line of the hydraulic system
Third: different pressures - ZU-H filter has three levels of pressure, H stands for high pressure 32Mpa, E stands for medium pressure 16Mpa, C stands for low pressure 6.3Mpa
A in the ZU-A filter represents a low pressure of 1.6Mpa
Fourth: the connection method is different - the former has tubular connection, flange connection, plate connection, inverted tube type, inverted flange type, flip-chip type
The latter is tubular, flanged, plate
Fifth: the filter model is different - the former is HX-10*#
The latter is TZX2-10*#
