For industrial applications demanding robust filtration under extreme pressure and corrosive conditions, the Eaton EH Series High Pressure Filter stands out as a premier solution. Designed with high-grade stainless steel, this filter housing is engineered to protect critical hydraulic and lubrication systems operating at pressures up to 6,000 psi (420 bar).
Product Overview: Eaton EH Series
The Eaton EH series consists of inline-mounted, stainless steel pressure filters capable of handling the most rigorous hydraulic environments. Unlike standard carbon steel housings, the EH series utilizes Stainless Steel (1.4571 / 316 Ti), making it the ideal choice for offshore, marine, and chemical processing industries where corrosion resistance is non-negotiable.
These filters are designed to absorb pressure peaks with a sufficient margin of safety, ensuring the integrity of your hydraulic circuit. With flow rates reaching up to 119 gpm (450 l/min), the EH series combines high throughput with precision depth filtration.
Key Features and Benefits
- High Pressure Capability: Rated for working pressures up to 6,000 psi (420 bar), suitable for heavy-duty hydraulic power units.
- Corrosion Resistance: Constructed entirely from EN10088-1.4571 (316 Ti) stainless steel.
- Manifold/Flange Mounting: Designed for compact integration directly onto hydraulic manifolds or systems to save space and reduce piping.
- Versatile Fluid Compatibility: Suitable for petroleum-based fluids, HW-emulsions, water-glycols, and most synthetic hydraulic fluids.
- High Intrinsic Stability: The filter elements are designed to withstand high differential pressures without collapsing.

Applications and Usage
The EH series plays a vital role in maintaining fluid cleanliness in sectors where equipment failure due to contamination is not an option. Common applications include:
- Offshore & Marine: Deck machinery, winches, and steering gear where saltwater corrosion is a constant threat.
- Process Industry: Chemical plants and refineries utilizing aggressive synthetic fluids.
- Power Generation: Pitch control systems and lubrication circuits in turbines.
- General Hydraulics: High-pressure testing rigs and mobile machinery.
Filter Element Technology
The EH housing accepts high-performance filter elements (such as glass fiber fleece) that provide deep filtration. These elements offer a high dirt-holding capacity, which translates to longer intervals between service changes and reduced maintenance costs. The flow direction is typically from outside to inside, maximizing the surface area used for contaminant capture.
