Premium Hydraulic Filter Cartridges for Clean Fluid Systems
Hydraulic filtration plays a crucial role in keeping hydraulic systems efficient, reliable, and long-lasting. Contaminants such as dust, metal particles, and sludge can damage components and reduce system performance. Hydraulic filter elements are designed to remove these impurities, ensuring that hydraulic fluid stays clean and machinery operates smoothly.
Filter elements are installed in different parts of a hydraulic system, including pressure lines, return lines, suction filters, and off-line filtration units. Their primary function is to protect pumps, valves, cylinders, and other critical components from contamination. Using high-quality filtration elements improves equipment lifespan, minimizes system downtime, and reduces maintenance costs.
At DURAfilter, we design and manufacture high-performance hydraulic filter elements that deliver reliable filtration across demanding industrial and mobile hydraulic environments. Our product range includes DURAfilter-branded cartridges, OEM replacement elements, and cross-reference filter cartridges compatible with leading hydraulic brands such as EPE and Bosch Rexroth. Each filtration element is engineered for durability, efficiency, and consistent performance even in harsh operating conditions.
Types of Hydraulic Filtration Media Offered by DURAfilter
Every hydraulic application has unique operating conditions, which is why choosing the correct filtration media is essential. DURAfilter provides several advanced filtration materials to match various performance requirements.
Glass Fiber Filtration Media (1–20 µm Absolute)
Glass fiber filter elements are ideal for systems that require high-efficiency filtration and strict fluid cleanliness levels. This filtration media provides excellent dirt-holding capacity and low resistance to fluid flow. These elements are widely used in precision hydraulic systems where particle contamination must be tightly controlled.

Stainless Steel Mesh Media (10–300 µm Nominal)
Stainless steel mesh elements are known for their mechanical strength and reusability. These filter elements can be cleaned and reused multiple times, making them a cost-effective option for heavy-duty industrial applications.
Sintered Metal Fiber Media (5, 10, 25 µm Nominal)
For hydraulic systems operating in high temperature or high viscosity environments, sintered metal fiber filtration offers stable and reliable performance. Its porous structure provides consistent filtration even under extreme operating conditions.
Paper Filter Media (5–25 µm Nominal)
Paper filtration elements are a practical and economical solution for auxiliary filtration or low-pressure hydraulic systems. They provide dependable contamination control while keeping operational costs low.
Dualglass (G6) and Stainless Fiber Media
Dualglass and stainless fiber media combine high particle retention with excellent durability. These elements support filtration ranges between 1 and 60 microns, making them suitable for applications requiring broader filtration performance.
Key Features and Advantages of DURAfilter Hydraulic Filter Elements
DURAfilter filtration products are built with advanced materials and precision manufacturing to ensure consistent hydraulic system protection.
Strict Quality Testing
Every hydraulic filter element undergoes rigorous testing to meet important international standards, including:
ISO 2941 – Collapse and burst resistance
ISO 2942 – Fabrication integrity
ISO 2943 – Fluid compatibility testing
ISO 3724 – Flow fatigue testing
ISO 16889 – Multi-pass filtration efficiency testing
These certifications ensure our filter elements maintain reliability even under demanding conditions.
High Dirt-Holding Capacity
Our filter cartridges are engineered with large dirt-holding capacity. This allows them to trap more contaminants before replacement is required, extending maintenance intervals.
Improved System Efficiency
Low pressure drop across the filtration media helps maintain smooth fluid flow. This improves overall system efficiency and reduces strain on pumps and valves.
Durable Construction
Premium materials such as glass fiber, stainless steel mesh, and sintered metal fiber allow our filtration elements to withstand high pressure, high temperature, and varying fluid viscosities.
Compatibility and Custom Hydraulic Filter Solutions
DURAfilter filter elements are designed to integrate easily with industrial hydraulic systems, mobile hydraulic equipment, and fluid power systems.
For applications that require unique specifications, we also manufacture custom hydraulic filter cartridges. Our engineering team can design filtration elements based on:
Required pressure rating
System flow rate
Filtration efficiency
Fluid compatibility
Temperature range
Our solutions are suitable for systems using standard hydraulic oil, synthetic fluids, phosphate esters, or water-based hydraulic fluids.
In addition to filtration elements, we also supply hydraulic breathers, strainers, and filter heads, ensuring your filtration system functions as a complete and efficient unit.
Industries That Use Hydraulic Filter Elements
DURAfilter products are trusted across industries where clean hydraulic fluid is essential for equipment performance.
Industrial Manufacturing
Hydraulic filter elements are used in presses, injection molding machines, and automated production equipment to maintain contamination-free fluid systems.
Mobile Hydraulics and Construction Equipment
Heavy machinery used in construction, mining, and agriculture relies on filtration elements to protect pumps and hydraulic components.
Power Generation
Hydraulic systems in turbines and control systems require high-pressure filter elements to maintain operational stability.
Marine and Offshore Systems
Marine hydraulic systems must withstand salt exposure, humidity, and harsh operating conditions. Reliable filtration ensures smooth operation of steering, propulsion, and deck equipment.
Oil and Gas Industry
Drilling and processing operations require high-performance hydraulic filtration to maintain equipment reliability in challenging environments.
How to Choose the Right Hydraulic Filter Element
Selecting the correct hydraulic filtration element ensures optimal system protection and efficiency.
1. Check Fluid Compatibility
Different hydraulic fluids have different chemical properties. Always select filter materials that are compatible with mineral oils, synthetic fluids, or water-based hydraulic fluids.
2. Select the Correct Micron Rating
Micron rating determines the size of particles a filter can capture.
Absolute micron rating (e.g., 1 µm): Removes nearly all particles of that size. Ideal for precision systems.
Nominal micron rating (e.g., 10 µm): Removes most particles but allows a small percentage to pass through.
3. Consider System Pressure and Flow Rate
Filter elements must withstand system pressure without collapsing. High-pressure systems require elements tested for burst resistance and structural strength.
4. Evaluate Maintenance Requirements
Systems with high contamination levels may require filter elements with higher dirt-holding capacity or reusable designs to reduce maintenance frequency.
