Introduction to the Eaton HYD ELA 103
In the world of industrial hydraulics and lubrication, equipment reliability is directly tied to fluid cleanliness. The Eaton HYD ELA 103 represents a high-performance solution within Eaton’s ELA series of stainless steel inline filters. Designed to handle operating pressures up to 580 psi (40 bar), this filter is engineered for systems that demand durability, intrinsic stability, and continuous operation.
As a distributor for premium filtration brands, Purecowater provides the Eaton ELA 103 to industries requiring robust filtration for petroleum-based fluids, HW-emulsions, and synthetic oils. This unit is particularly valuable in environments where corrosion resistance and high dirt-retaining capacity are non-negotiable.

Key Features of the ELA 103
The Eaton ELA 103 distinguishes itself with features designed to minimize downtime and maximize protection for downstream components.
- Stainless Steel Construction: The housing is crafted from stainless steel, offering superior resistance to aggressive environments and fluids compared to standard carbon steel housings.
- Integrated Change-Over Valve: A standout feature of the ELA series is the integrated three-way change-over valve located in the middle of the housing. This allows operators to switch from the dirty filter side to the clean filter side without interrupting system operation, a capability crucial for continuous process lines.
- High Intrinsic Stability: Designed to absorb pressure peaks with a sufficient safety margin, ensuring the housing integrity during hydraulic surges.
- Versatile Fluid Compatibility: Suitable for mineral oils, lubrication oils, and most synthetic hydraulic fluids.
