The Kleenoil Bypass Micro-filtration System is installed to filter the fluid whenever there is oil pressure. Our unique design allows the water to be extracted from the fluid and still allows the larger oil molecules to pass through unchanged. The dirt and wear particles are trapped in the filter giving you a continuous self-contained recycling system. Changing the Kleenoil Filter Cartridge takes much less time than a conventional oil change, and can be done in less than 10 minutes! -Removes particles down to 1 micron -Removes 99.95% of all water -Extends oil life up to 5x (10x for hydraulic)
