The Kleenoil Filtration System is a bypass oil filter that passes only a small portion of the total oil flow through a very dense filter cartridge at about 2 to 3 quarts per minute. At this speed, it is possible to remove particles down to 1 micron and totally remove water, greatly decreasing engine wear and prolonging oil life. Kleenoil can eliminate water and particle contamination, extend oil life up to 5 times and hydraulic oil up to 10 times, reduce engine wear and component wear, dramatically reduce downtime, remove particles down to 1 micron, and is applicable to engines as well as hydraulic systems.
