Filtration Rating
Filters are rated on the basis of their ability to separate particulate matter of certain size levels from a fluid, under specific operating conditions. Click here to read this whitepaper.

Ozone Questions And Answers
What is Ozone? Ozone is active oxygen, O3. It occurs naturally in the Earth's atmosphere to protect us from the Sun's harmful rays. Click here to read this whitepaper.

Principles of Separation / Coalescence
Separation: Separating oil or solvents from water by mechanical means involves the application of some basic physical principles. First, oil and water are not soluble in each other. Even so called soluble oils are really an emulsion-not a true solution. Second, water is denser than oil or petroleum based solvents. These properties tend to result in separation naturally unless other factors interfere. Click here to read this whitepaper.

New Engines and Oil Require Better Filters
1991 Emissions Standards Mean Increased Engine Wear. With the 1991 models tough new exhaust emission laws will be in effect. New fuels, new oils, and new engine designs are all needed to help meet the requirements. Some fuels, and many oils have already been formulated, and are now in the marketplace. The engines are in their final stages of development, and will be out soon. Click here to read this whitepaper.

Since 1966 Engineers knew that particles smaller than Five microns (5µ) Caused most engine wear!
"….particulate contamination (1 micron and smaller) is a contributing factor to wear in valve lifters." Click here to read this whitepaper.

Measuring Bearing Oil Film Thickness
The relationship between high temperature engine oil viscosity and its load carrying capability is not well established. A new test method now offered at Southwest Research Institute measures the bearing oil film thickness (BOFT) of lubricants in a fired engine under various operating conditions.
