Introduction to Eaton Hydraulic Filtration Solutions
At Purecowater, we specialize in tackling complex solid and liquid filtration problems by distributing top-tier equipment from industry leaders like Veolia, WTS, and Eaton. For industrial applications requiring robust, continuous filtration without system downtime, the Eaton EDU 635 Series stands out as a premier stainless steel pressure filter solution.
This product guide details the technical capabilities, applications, and specifications of the Eaton EDU 635, a change-over pressure filter designed for reliability and performance in demanding hydraulic environments.
What is the Eaton EDU 635?
The Eaton EDU 635 is a stainless steel pressure filter featuring a duplex (change-over) design. Unlike simplex filters that require system shutdown for maintenance, the EDU 635 incorporates a change-over ball valve between two filter housings. This allows operators to switch flow from the dirty filter side to the clean filter side instantly, ensuring zero interruption to operation.
Designed for working pressures up to 464 PSI, this unit is engineered to absorb pressure peaks with a sufficient safety margin, making it ideal for critical hydraulic and lubrication circuits.
Key Features
- Continuous Operation: The change-over ball valve enables element replacement while the system remains live.
- High Stability Elements: Utilizes star-shaped, pleated filter material supported by a perforated core tube.
- Versatile Fluid Compatibility: Suitable for petroleum-based fluids, HW emulsions, water glycols, and most synthetic fluids.
- Installation: Designed for vertical installation with accessible maintenance ports.

Filter Element Options
The performance of the EDU 635 relies on Eaton’s high-quality filter elements. Depending on the required cleanliness level, users can select from various materials:
- Wire Mesh (G): Stainless steel mesh for coarser filtration (25G, 40G, 80G). Cleanable to a limited extent.
- Microglass (VG): Disposable elements for fine filtration (down to 3VG/5µm). Recommended for filtration finer than 40 μm [eaton.com].
- API Microglass: Specified for API standards (10API, 25API).
Applications and Suitability
The EDU 635 is designed for industries where system reliability is paramount and fluid cleanliness cannot be compromised. Common applications include:
- Hydraulic Systems: Protecting pumps and valves from solid contaminants.
- Lubrication Circuits: Ensuring clean oil flow to bearings and gears.
- Marine and Offshore: Due to its robust stainless steel construction and resistance to corrosion.
- Power Generation: For turbine and control fluid filtration.
