Introduction to the Eaton HYD DA 103 Duplex Filter
The Eaton HYD DA 103 (specifically part of the DA Series ASME Design) is a high-performance duplex pressure filter designed for hydraulic and lubrication systems. It is engineered to provide continuous filtration, ensuring that your machinery remains protected from contamination without the need for costly system shutdowns during maintenance.
As a leading solution in low-to-medium pressure applications, the DA 103 series stands out for its robust carbon steel construction and compliance with ASME VIII Div. 1 standards. Whether you are managing petroleum-based fluids, synthetic hydraulic fluids, or lubrication oils, this filter unit offers high intrinsic stability and dirt-retaining capacity.
How the DA Duplex Design Works
The primary advantage of the Eaton DA 103 is its duplex configuration. Unlike simplex filters that require flow interruption to change a clogged element, the DA series features two filter housings connected by a changeover valve. This design allows operators to:
- Switch Flow: Divert fluid flow from the dirty filter chamber to the clean one using a handle mechanism.
- Equalize Pressure: A built-in pressure equalization system creates a smooth transition, preventing hydraulic shock or pressure drops during the switch.
- Service Continuously: The “offline” housing can be opened, and the element replaced while the system continues to run at full capacity.
Technical Specifications
The DA 103 series is built to rigorous standards to ensure reliability in industrial environments. Below are the key technical specifications for this series.

Filter Elements and Depth Filtration
The Eaton DA 103 utilizes high-efficiency filter elements designed for depth filtration. This method is superior for hydraulic applications as it captures contaminants throughout the thickness of the media, rather than just on the surface. This results in:
- Higher Dirt-Holding Capacity: Longer intervals between element changes.
- Excellent Filtration Efficiency: Utilizing glass fiber fleece (VG) or paper (P) media.
- Versatility: Options available for various micron ratings fitting specific cleanliness requirements (e.g., ISO 4406 standards).
Key Features and Benefits
- Zero Downtime: The defining feature of the duplex design is the ability to maintain system operation 24/7.
- ASME Certified: Designed in accordance with ASME VIII Div. 1, ensuring safety and quality for pressure vessels.
- Operational Safety: The switching mechanism is designed to prevent inadvertent flow shut-off.
- Broad Compatibility: Suitable for mineral oils, HW-emulsions, and most synthetic hydraulic fluids.
Common Applications
The DA 103 series is ideal for critical industries where fluid cleanliness is paramount to equipment longevity.
| Power Generation | Turbine lubrication systems and control hydraulics. |
| Oil & Gas | Compressor lube oil and sealing gas systems. |
| Steel & Manufacturing | Heavy-duty hydraulic presses and recirculation lines. |
| Marine | Main engine lubrication and steering gear hydraulics. |
