Use cases & applications
High-Pressure Hydraulic Systems
Ideal for use in hydraulic power units operating at high pressures, where robust filtration is critical to protect pumps and valves from wear. The 210 bar collapse pressure ensures reliability under extreme conditions.
Continuous-Duty Industrial Machinery
Suitable for machinery that runs continuously, such as in manufacturing plants, where consistent filtration quality is needed to maintain system cleanliness and reduce downtime.
Mobile Hydraulic Equipment
Works well in mobile equipment like excavators or loaders, where the wire mesh media can handle varying flow rates and shock loads without clogging.
Frequently asked questions
How do I confirm that this filter fits my hydraulic system?
Check the total height (373 mm), largest inner diameter (47.5 mm), and largest outer diameter (83.5 mm) against your existing filter. Also verify the thread type and port size from your system specifications.
What does the 90 µm filtration rating mean?
The 90 µm rating indicates the filter captures particles larger than 90 microns. The wire mesh media is cleanable and offers low flow resistance, suitable for systems where fine filtration is not required.
What are the exact dimensions and thread specifications?
The filter has a total height of 373 mm, largest inner diameter of 47.5 mm, and largest outer diameter of 83.5 mm. For thread details, consult your system's port thread as this filter does not include a thread specification.
Is this filter a genuine OEM part?
