To explain it as easily as possible ISO & NAS coding are used to provide an comparative scale for Oil Cleanliness. By having an international standard, it assists industry consumers and suppliers by having a measurement scale by which they can base Oil Cleanliness standards on. This technology is based on and is measured by the level of particle contamination present per milliliter of fluid.

At Pure Oil we take pride in our Oil being at a cleanliness level of ISO 13/11 NAS 5. This level is far cleaner than brand new oil. Through our Effective Filtration Services, Our Experience and our Internally Renowned Products we can ensure that we provide our clients with this cleanliness level or even better.
By having Oil circulating through your system with high contamination can likely affect: machine efficiency, overall performance, higher operational costs, & lower life expectancy of your machines.

Not only can contamination 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. So why wouldn’t you want the oil circulating your machines to be the cleanest it can be.
