MAGNETIC FILTRATION

     
      

  

 

Studies have shown that for each grade the ISO code is lowered, the life of a hydraulic component 

can be doubled or tripled!

As shown in the chart, new oil is approximately rated at 18/15. Kleenoil Bypass Filters will attain 

ISO 4406 to a standard of less than 14/11!
