Filter elements are integral to every hydraulic filtration system. They remove contaminants, protect vital components and keep hydraulic fluid clean to maintain consistent system performance. Whether installed in return lines, suction filters, pressure lines, or off-line filtration units, high-quality filter elements ensure longer equipment life and fewer maintenance interruptions.
At DURAfilter, we manufacture high-performance hydraulic filter elements trusted across industrial and mobile hydraulic applications. Our products include DURAfilter-branded filter cartridges, OEM replacements for select brands such as EPE and Bosch Rexroth, and high-quality cross-reference elements compatible with leading hydraulic systems. Each filtration element we produce is engineered for dependability, efficiency, and long service life under demanding operating conditions.
Types of Hydraulic Filtration Media Offered by DURAfilter
Every hydraulic system operates differently, so the right filtration media matters. DURAfilter offers multiple media options to match specific performance goals:
- Glass Fiber (1–20 µm absolute): These hydraulic filtration elements are ideal for systems requiring high-efficiency filtration and consistent cleanliness levels. Glass fiber media provides excellent dirt-holding capacity and low initial pressure drop.
- Stainless Steel Mesh (10–300 µm nominal): These hydraulic filtration elements are perfect for heavy-duty and reusable applications. It offers mechanical strength and easy cleaning for long-term cost savings.
- Sintered Metal Fiber (5, 10, 25 µm nominal): Suited for high-temperature or high-viscosity fluids, the porous structure of these hydraulic filter cartridges ensures stable performance even in extreme environments.
- Paper Media (5–25 µm nominal): A practical and economical option for low-pressure or auxiliary filtration systems, these hydraulic filtration elements offer reliable contamination control.
- Dualglass (G6) and Stainless Fiber Media: These filtration elements are ideal for applications demanding enhanced particle retention and durability across a wide micron range (1–60 µm).

How to Choose the Right DURAfilter Hydraulic Filtration Element
Here are some key factors to consider when selecting the right DURAfilter filter element for your hydraulic filtration system:
- Identify the Fluid Type and Compatibility: Different hydraulic fluids, such as mineral oil, synthetic oil, or water-based fluids, require filter elements that can handle their unique chemical properties. Ensure that the filter element material is compatible with your system’s fluid properties, such as fluid viscosity, fluid contaminants, and fluid temperature range to avoid degradation or failure.
- Determine the Required Filtration Efficiency (Micron Rating): The micron rating defines the size of particles the filter element will capture. Depending on your system’s cleanliness requirements, you will need a filter with the appropriate micron rating.
- Absolute micron rating (e.g., 1 µm) guarantees a high level of particle retention (99.9%). Ideal for high-precision systems.
- Nominal micron rating (e.g., 10 µm) reflects the nominal size range of particles removed but may allow a small percentage of smaller particles to pass through.
- Consider System Pressure and Flow Requirements: The operational pressure and flow rate in your system directly impact the filter element’s performance. A filter element must be able to withstand the system’s pressure without collapsing and maintain optimal flow capacity. If your system operates at high pressures, select a pressure filter element with high collapse and burst resistance (tested under ISO 2941).
- Plan for Maintenance and Replacement Cycles: Consider the maintenance needs of your filtration system and how often the hydraulic filter elements will need to be replaced or cleaned. Systems with high dirt loads or frequent cycling may require more durable, easy-to-clean elements.
