Hydraulic oil

Reliable hydraulic systems start with clean hydraulic oil

Clean hydraulic oil is the foundation of reliable machine performance. In every hydraulic system, the smallest particles, moisture and oxidation residues are enough to cause sticking valves, pressure instability and accelerated pump wear.


These issues rarely appear suddenly, but develop over time as contamination accumulates in the oil and moves through the system during normal operation. When the oil is allowed to degrade, components work harder, heat builds up and efficiency drops.


The result is more downtime, increased maintenance hours and higher annual operating costs. By keeping hydraulic oil clean and dry, you protect the system against the most common causes of failure and extend the lifetime of critical components.


Continuous offline filtration makes this possible by removing the very contaminants that inline filters cannot handle. The outcome is stable operation, longer oil life and predictable performance in demanding industrial environments.

Stop paying twice by filtering out unwanted costs

Spanner symbol representing maintenance work and troubleshooting time.

Maintenance hours and troubleshooting

Contamination causes unstable valve and pump behaviour, increasing the need for cleaning and adjustments.

Valve symbol representing valve and pump malfunction or wear.

Valve and pump failures

Particles accelerate wear in critical components, leading to sticking, loss of performance and premature failure.

Gear with exclamation mark symbol representing system faults and production stoppages.

Production downtime

Dirty oil triggers valve and pump malfunctions that slow or stop production.

Dollar symbol representing oil costs and increased operating expenses.

Annual oil consumption

Degraded oil must be replaced more often, increasing cost and waste.

How it works

Outcome for maintenance teams

Upward trend arrow icon representing extended oil service life through improved contamination control.

Extended oil lifetime

Effective contamination control slows oxidation and degradation, allowing hydraulic oil to remain in service significantly longer, often several years in stable systems

Mechanical component icon representing reduced wear on valves, pumps, and other system parts.

Reduced wear on critical components

Cleaner oil minimizes abrasive particles that cause premature wear on servo valves, pumps, and proportional valves, preserving system responsiveness

Shield with checkmark icon representing improved reliability and fewer unexpected equipment shutdowns.

Fewer unplanned stoppages

Stable oil cleanliness reduces failure events linked to contamination, helping prevent unexpected shutdowns and production interruptions.

Droplet icon representing stable oil cleanliness levels meeting ISO standards.

Consistent ISO cleanliness levels

Hydraulic systems maintain target cleanliness classes, such as ISO 16/14/11, even under demanding operating conditions, ensuring predictable performance.

Clean Oil Is Not a Recommendation. 

It Is a Reliability Strategy.

Understand contamination mechanisms, ISO codes, water control, and how to extend oil and component lifetime.

Case studies show that hydraulic systems operating at ISO codes above 18/16/13 have failure rates several times higher than systems kept clean. Clean oil directly translates to higher reliability and lower operating costs.
