3501/3502
Line filter
TThe line filter is installed in-line to maintain the oil purity level in the hydraulic piping and protect hydraulic equipment from contaminants.
- Downward extraction type element
- Select from many options like indicators, relief valves, etc
- Choose from 2 types of element lengths for all inner diameters
