Use cases & applications
High Contamination Environments
In dusty or dirty settings like construction sites, the 25-micron wire mesh traps abrasive particles that can damage hydraulic components. Using this filter extends the life of pumps and motors, reducing unplanned downtime.
Continuous Duty Operations
For 24/7 industrial machinery, the integrated 3 bar bypass valve prevents oil starvation if the filter becomes heavily loaded. This allows operations to continue safely until the next scheduled maintenance window.
Fleet Standardisation
This filter replaces multiple brand-specific filters across different machine makes. Standardising on this single part simplifies inventory management and reduces procurement complexity for large workshops.
Cold Climate Start Up
In low temperatures, hydraulic oil thickens and resists flow. The bypass valve opens at 3 bar to maintain circulation during warm-up, protecting the pump from cavitation damage and ensuring reliable cold starts.
Frequently asked questions
How can I be sure this filter fits my Hydac equipment?
This filter is a direct replacement for Hydac hydraulic filters and cross-references with many popular brands like Fleetguard and Internormen. Compare your existing filter's dimensions with ours: total height 196 mm, largest outer diameter 95 mm, and inner diameters of 48.5 mm and 46 mm. If your current element matches these measurements, it will fit.
What is the filtration rating of this element?
It features a wire mesh media with a 25-micron absolute rating. This level of filtration effectively removes fine contaminants from hydraulic oil, protecting sensitive components from wear and ensuring system reliability.
What are the critical dimensions to check before ordering?
The filter is a drop-in element with no threads. Confirm your housing accepts an overall height of 196 mm, an outer diameter of 95 mm, and inner diameters of 48.5 mm (largest) and 46 mm (smallest). The flow direction is out-to-in, and the bypass valve is set at 3 bar.
Is this an original Hydac part?
No, this filter is a high-quality aftermarket filter built to the original dimensions and ratings. It is not a genuine Hydac product but delivers equivalent performance and durability at a significantly lower cost.
How do I install this replacement filter?
Follow standard hydraulic filter replacement practices. Depressurise the system, remove the old element, and insert this filter with the flow arrow pointing out-to-in. Replace the housing seal, then re-tighten according to the manufacturer's torque specifications. Prime the system if needed before restarting.
What delivery and guarantee do you offer?
We provide worldwide shipping with full tracking on every order. All purchases are covered by our 30-day money-back guarantee and price-beat promise. If you find a lower price elsewhere, we will match or beat it. Simply return the filter within 30 days for a full refund if you are not satisfied.
