Particles in lubricating oil—especially hard metallic contaminants—are an invisible killer of industrial equipment. Even microscopic debris can cause significant mechanical and chemical damage over time. If left unfiltered, these particles can:
Accelerated Wear – Hard particles act like fine sandpaper, grinding friction surfaces and shortening the lifespan of bearings, gears, and pumps.
Clog Oil Passages – Accumulated contaminants can block oil lines, disrupt flow, and lead to lubrication failure.
Speed Up Oxidation – Certain metal particles catalyze oxidation reactions, causing oil to degrade faster and lose its protective properties.
Affect Equipment Precision – In hydraulic or servo systems, even particles smaller than 5 microns can cause malfunctions, unstable pressure, or control failure.
A lubricating oil purifier is designed to remove particulate matter effectively through multi-stage filtration. Regular purification provides measurable operational and economic benefits:
Extend Equipment Life – Cleaner oil minimizes surface wear and protects precision components.
Prolong Oil Service Life – Maintaining oil cleanliness reduces the need for frequent oil changes, cutting costs and waste.
Reduce Downtime – Stable lubrication ensures reliable machine operation and fewer unexpected shutdowns.
Improve Energy Efficiency – Clean oil lowers friction losses, improving mechanical efficiency and performance.
The performance of an oil purifier depends on its filtration accuracy, usually measured in micrometers (µm). Typical levels include:
Standard Filtration: Removes particles around 25 µm (about one-third the thickness of a human hair).
Precision Filtration: Removes particles as small as 10, 5, or 3 µm.
Ultra-Fine Filtration: Advanced systems can capture particles down to 1 µm or smaller.
Filtration efficiency is often evaluated using the ISO 4406 cleanliness standard. A high-performance purifier can achieve cleanliness levels such as ISO 15/13/10 or better, where lower numbers indicate cleaner oil.
Removing particulate matter from lubricating oil is not just maintenance—it’s essential protection for your equipment and operating budget.
A quality oil purifier can achieve deep, micron-level filtration that prevents wear, extends oil service life, and improves overall system reliability.
When selecting a lubricating oil filtration system, always match its filtration accuracy to the sensitivity of your machinery. The right purifier will ensure optimal oil cleanliness, stable operation, and long-term savings.
