Keeping Contaminants Out is Better Than Taking Them Out

When improving fluid cleanliness, it is easier (and cheaper) to exclude contaminants by ensuring seals, vents and breathers are in good shape rather than to filter out contaminants when they are already inside a component. Consider using a full-flow spin-on filter (with an appropriate beta rating) as an air filter. Because the differential pressure across an air filter is lower than across a full-flow oil filter, oil filters are typically more efficient at removing particles from the air than they are from oil.

How Particle Contamination Affects Oil

From the book: Oil Analysis Basics

Particles, especially catalytic metal particles like copper, iron and lead increase the rate at which oxidation occurs. Particles also strip the oil of its polar additives, including antiwear additives, extreme pressure additives, rust inhibitors and dispersants. Also, numerous very small particles in stable suspension can cause the oil's viscosity to increase.

More about the book Oil Analysis Basics


Elevation Assists in Contamination Control

The higher a machine is located above ground level, the lower the ingression of particles into the oil.

A Guideline for Machine Cleanliness Levels

As a general guideline, the cleanliness of an oil in a machine before starting operation should be two ISO classes below warning levels (targets) for that machine.


Most Commonly Found Contaminants in Industrial Lubricants

Some of the most common industrial contaminants found in lubricating oil systems are solid particles such as dirt and dust, water, oxidation products and air.
