Digoema DGMH4520, direct aftermarket replacement. This filter is a hydraulic filter element built to replace filters in Hydac hydraulic systems. The media is inorganic microfibres with a 12-micron rating, delivering reliable particle capture from hydraulic fluid. Flow direction is out-to-in, suitable for a range of operating pressures.
This aftermarket filter cross-references directly to elements from Digoema, Dynapac, Fai Filtri, Hydac, and Oxfil. It is engineered to the original dimensions and ratings, offering a cost-effective alternative with the same fit and performance. Every filter comes with a
30-day money-back guarantee and a
price-beat guarantee.
With a height of 395 mm and an outer diameter of 88 mm, it installs simply into the filter housing. The inorganic microfibre media resists moisture and chemical degradation, supporting consistent filtration over the service interval.

Use cases & applications
Dusty Worksites
In quarries, mines, or construction sites where airborne dust is high, the 12-micron media prevents fine particles from entering the hydraulic circuit. This keeps pumps, valves, and cylinders free from abrasive wear, extending component life.
Continuous-Duty Machinery
For excavators, compactors, or stationary hydraulic systems running long shifts, the inorganic microfibre media maintains consistent flow and filtration efficiency. It resists plugging under sustained loads, reducing unplanned filter changes and downtime.
Multi-Brand Fleets
Because this filter cross-references several filter brands, you can hold a single part number for multiple machines. This simplifies inventory, cuts carrying costs, and ensures you have the right replacement on hand when due.
Routine Maintenance Intervals
The filter is a direct drop-in replacement that matches the original housing dimensions. Technicians can swap it quickly during scheduled service, minimising labour time and returning the machine to production sooner.
Frequently asked questions
Will this filter fit my hydraulic system?
It is a direct replacement for filters used in Hydac hydraulic equipment. It cross-references to part numbers from Digoema, Dynapac, Fai Filtri, Hydac, and Oxfil. Verify that your existing filter matches these dimensions: 395 mm total height, 88 mm outer diameter, and 40.5 mm inner diameter on both ends.
What is the filtration rating and media type?
The filter uses inorganic microfibre media rated at 12 microns absolute. This means it captures particles as small as 0.012 mm. The media is inherently resistant to moisture and chemical degradation, preserving filtration performance across the service interval.
What are the exact dimensions and does the filter have threads?
The filter has a total height of 395 mm, an outer diameter of 88 mm, and a consistent inner diameter of 40.5 mm at both the top and bottom openings. It seals via the inner diameter onto the housing spigot, so no threaded connection is required or present.
Is this a genuine OEM filter?
No, this is an aftermarket replacement element manufactured to the original dimensions and ratings. It provides equivalent fit, form, and function at a more affordable price. It is not a genuine Hydac, Digoema, Dynapac, Fai Filtri, or Oxfil part.
How do I install this filter?
Installation is straightforward. Remove the old filter, clean the housing, inspect the sealing surfaces, and insert the new element. Ensure the housing o-ring is in good condition and tighten the cover to the manufacturer’s torque specification. No special tools are needed.
What are the delivery options and guarantee?
We ship worldwide with tracking on every order. Your purchase is covered by a 30-day money-back guarantee and our price-beat guarantee. If you find a lower advertised price on an identical in-stock item, we will beat it.
