Eaton HYD DA 251: Advanced Duplex Pressure Filter for Continuous Operation
Efficient hydraulic filtration is the backbone of industrial reliability. The Eaton HYD DA 251 is a high-performance duplex pressure filter designed to ensure cleanliness in hydraulic and lubrication systems where shutdowns for filter changes are not an option. Purecowater is proud to distribute Eaton’s advanced filtration solutions, helping facilities minimize downtime and protect critical machinery.
Product Overview
The Eaton DA series, including the Model 251, serves as a “gatekeeper” for your fluid systems. As a change-over duplex filter, it consists of two filter housings connected by a switching valve. This design allows one housing to remain in operation while the other is isolated for maintenance or element replacement. This capability is essential for continuous process industries such as power generation, marine propulsion, and heavy petrochemical processing.
Unlike simplex filters that require system depressurization to service, the DA 251 allows for 24/7 continuous operation, effectively removing solid particulate contamination from hydraulic oils, lubrication oils, and other process fluids.
Key Benefits of the DA 251
- Uninterrupted Flow: Switch between filter chambers without stopping the system flow.
- Component Protection: Extends the life of pumps, valves, and turbines by maintaining fluid cleanliness classes.
- Robust Construction: Designed to withstand pressure fluctuations and harsh industrial environments.
- Versatile Media Compatibility: Compatible with a wide range of filter elements, including glass fiber, wire mesh, and paper, to target specific micron ratings.
Technical Specifications
The Eaton HYD DA 251 is engineered for medium-pressure applications. Below is an overview of the typical specifications associated with the DA series configuration.
| Specification | Details |
|---|---|

| Fluid Compatibility | Hydraulic oils, Lubrication oils, Synthetic fluids |
| Mounting | Inline or Flanged connections |
| Material Options | Carbon Steel, Stainless Steel, Aluminum (model dependent) |
| Application Focus | Turbine Lube Oil, Gearboxes, Compressors |
Primary Applications
The DA 251 is particularly suited for industries where fluid cleanliness directly correlates to operational safety and efficiency.
1. Power Generation (Gas & Steam Turbines)
Turbine bearings require a constant supply of clean oil. The DA 251 removes varnish precursors and particulates that can cause bearing failure or servo-valve sticking.
2. Marine & Offshore
Used in propulsion systems and auxiliary hydraulic circuits, ensuring reliability in remote environments where maintenance resources are limited.
3. Steel & Heavy Industry
Protects hydraulic control systems in rolling mills and presses where high contamination loads are common.
