CLEAN OIL KNOWLEDGE
Clean Oil Matters
Clean oil is the foundation of reliable machinery.
Explore how oil contamination affects equipment, how offline filtration works, and what you should consider when evaluating the right filtration solution.

REAL IMPACT
of failures in hydraulic and lubrication systems are caused by contaminated oil.
Control contamination - fewer failures, longer oil life, lower total cost. Contamination is the leading cause of failure in every oil-filled system.
Where would you like to start?
What is contaminating my oil?
Understand how particles, water, oxidation products and acidity affect oil performance, components and equipment reliability.
TECHNICAL GUIDE
How should I evaluate oil filtration?
Learn which technical factors matter, including oil type, oil volume, contamination, viscosity, temperature and operating conditions.
Why use offline filtration?
See how offline filtration continuously cleans oil independently of the machine's main lubrication or hydraulic system.
How does CJC® filtration work?
Understand how CJC® filter inserts remove fine particles, water and oil degradation products.
THE FUNDAMENTALS
Why clean oil is critical for every oil-filled system
01
Oil contamination impacts performance
Particles, water, air, and degradation by-products slowly damage pumps, bearings, valves, and gears. Even microscopic contaminants accelerate wear, reduce efficiency, and lead to costly downtime.
02
Clean oil extends equipment life
Effective filtration removes the root cause of failure. The result: higher uptime, less maintenance, and longer equipment lifetime.

“80% of all oil related failures and breakdowns are caused by contaminated oil.”
