Filtration

Cooper Fluid Systems are a leading service provider of Offline Filtration solutions. Improved oil cleanliness greatly impacts the reliability and life of components, in turn reducing unscheduled downtime of equipment.

Overview

Cooper Fluid Systems are a leading service provider of Offline Filtration solutions. Improving oil cleanliness provides increases component life, improves efficiency, reduces unplanned maintenance, increases oil life and also reduces machine downtime.

Offline filtration, also known as Kidney Loop, systems allow oil to be filtered in a separate system which allows for the control of flow and pressure. This facilitates the use of elements that are capable of high dirt holding capacity, subsequently removing contaminants, water and degradation products (varnish) with a superior efficiency than standard inline systems.

Continuous Fluid Conditioning

Kidney loop filtration solutions for hydraulic, lubrication and gearbox systems across Australian industry

Our highly skilled and knowledgeable team can assist with designing, installing and maintaining an Offline Filtration systems suitable for your requirements. All solutions are supported by our national network of 12 branches.

Up to 80% of Hydraulic Failures Are Contamination-Related.
Offline filtration is one of the most cost-effective investments you can make in the reliability and longevity of critical fluid power assets.

How It Works

1. Draw from Reservoir
A dedicated pump draws fluid continuously from the bottom of the reservoir or sump.
2. Filter & Condition
Fluid passes through a high-efficiency filter element, removing particulate and water contamination.
3. Optional Conditioning
Heat exchangers or desiccant breathers can be integrated to control fluid temperature and moisture.
4. Return Clean Fluid
Filtered fluid is returned to the reservoir, maintaining target ISO cleanliness levels continuously.

Our Capabilities

  • Removes water and oil from a system
  • Impervious to system shocks
  • Applicable to diesel, oil and water glycol
  • In-cab and remote monitoring
  • Non-intrusive to existing system
  • Can remove 50% of 0.8-micron particles or 98% of 3-micron particles in a single pass
  • Superior dirt holding capacity when compared to surface filtration

Key Benefits

Extended Component Life

Maintaining target fluid cleanliness significantly extends the service life of pumps, valves, cylinders, and bearings.

Reduced Unplanned Downtime

Fewer contamination-related failures means less unplanned maintenance and improved production availability.

Lower Maintenance Costs

Extended fluid and component life reduces the frequency of oil changes, part replacements, and repair callouts.

Operates During Downtime

Because the circuit is independent, filtration continues even when the host machine is shut down or idle.

Measurable Cleanliness Targets

ISO 4406 particle counting gives you quantifiable data to verify system performance and meet OEM requirements.

Retrofit-Friendly

Offline systems can be added to existing equipment with minimal modification, making them ideal for reliability upgrades.
