ISO 16/14/11 NAS 5 Technology 

ISO & NAS coding is used to provide a comparative scale for oil cleanliness. The ISO cleanliness codes are international standards for fluid cleanliness. This technology is based and measured by the level of particle contamination present per millilitre of fluid. 

By having oil circulating through your system with high contamination can likely affect; machine efficiency, overall performance, increase operational costs, and lower the life expectancy of your machines. 

Not only can contaminate's ruin the machine but it can also reduce the life span of the oil. The higher the pollution of contaminants within the oil, the faster acid develops and the faster it loses all its physical and chemical properties. The only solution is to change the oil. Therefore, why wouldn’t you want the oil circulating through the machine to be at the cleanest?
