Maintaining the cleanliness of hydraulic fluids and lubricants is critical for the longevity of industrial machinery. The Eaton US 20 Stationary Off-Line Filter Unit is a compact, high-performance solution designed to serve high-viscosity applications where reliability is non-negotiable. As a trusted distributor for Eaton Filtration, Purecowater provides this unit to help facilities optimize their oil service operations.
What is the Eaton US 20?
The Eaton US 20 is a stationary off-line filter unit specifically engineered for the fine filtration, filling, or flushing of hydraulic systems. Unlike in-line filters that handle the full pressure and flow of a working system, this off-line unit operates independently. It utilizes a dedicated gear pump driven by an electric motor to draw oil from a reservoir, pass it through high-quality filter elements, and return the purified oil to the tank.
Ideally suited for gearboxes and systems using mineral oil-based hydraulic fluids, the US 20 is designed to remove contaminants such as dirt particles and water, ensuring the operating fluid maintains the required cleanliness class.
Key Features
- Compact Design: The unit’s small footprint allows it to be easily integrated into cramped industrial environments.
- Unattended Operation: Once started, the unit works without constant supervision, utilizing safety valves to ensure secure operation.
- Tool-Free Maintenance: Filter elements can be replaced easily without the need for specialized tools, reducing downtime.
- High Dirt Holding: The elements are designed for maximum capacity, extending the intervals between service.
- Versatile Functionality: Can be used for continuous polishing, transferring fluids during tank filling, or flushing systems after maintenance.

Performance Capabilities
The Eaton US 20 reinforces existing in-line filters by handling the “kidney loop” filtration duties. This results in a significantly longer service life for both the system components and the operating fluids. The unit is capable of handling fluids with a maximum allowable dirt particle size of < 200μm, refining them down to as low as 4 microns depending on the element selected.
Applications
This unit is versatile and can be deployed across various industries, including:
- Power Generation: Filtration of turbine oils and control fluids.
- Manufacturing: Hydraulic presses and injection molding machines.
- Marine: Gearbox lubrication and hydraulic steering systems.
- Construction & Mining: Maintenance of mobile equipment fleets (during service intervals).
