Use cases & applications
High-Contamination Environments
Operating hydraulic equipment in dusty or dirty settings, such as on construction sites, exposes oil to abrasive particles. The 7 µm microfiber media captures these contaminants early, preventing scoring and wear inside cylinders and motors.
Continuous-Duty Machinery
For systems that run long shifts without downtime, clean oil is critical. This element helps maintain fluid cleanliness over extended intervals, reducing the risk of unscheduled stops and protecting components from fatigue failure.
Fleet Maintenance Simplification
When servicing multiple Hydac-equipped machines, carrying one filter that fits across a range of systems streamlines inventory. This filter consolidates stock and cuts procurement time, without compatibility concerns.
Scheduled Preventive Maintenance
Replacing hydraulic filters at fixed intervals ensures consistent protection. With this direct-fit element, maintenance teams can stick to service schedules confidently, knowing the new filter matches the original specification exactly.
Frequently asked questions
Will this filter fit my Hydac system?
Yes, this filter is a direct replacement for Hydac filter elements measuring 116 mm in height, 49.5 mm outer diameter, and 24 mm inner diameter. Confirm your existing element matches these dimensions to ensure proper fit.
What micron rating does this filter have?
It is rated at 7 µm using inorganic microfibers media. This rating indicates the filter’s ability to capture particles down to 7 microns, providing effective contaminant removal for most industrial hydraulic applications.
Are there any threads or special dimensions I need to check?
There are no threads on the element itself. It is a drop-in style designed to fit inside the housing. The key dimensions are a total height of 116 mm, largest outer diameter of 49.5 mm, and largest inner diameter of 24 mm. Always verify these against your current element.
Is this a genuine Hydac filter?
No, this is an aftermarket filter manufactured to the original dimensions and ratings for Hydac-compatible elements. It delivers equivalent performance and will not void your equipment warranty when used as a direct service replacement.
How do I install this replacement filter?
Installation is simple. Remove the old element from the housing, clean the housing interior and sealing surfaces, then insert the new element ensuring the flow direction is Out-In. Reassemble the housing following your equipment’s manual, and check for leaks before restarting the system.
