Because in any type of filter the oil is made to pass through a filtering material. In a KLEENTEK cleaner, the oil flows within an electrostatic field, whose forces attract and hold the dirt particles.

As thousands of customers have been able to verify, KLEENTEK cleaners do not alter the additives in the oils. Actually, the natural consumption of the additives is appreciably slowed down.

It is the only technology that removes all types of contaminant from the oils, regardless of particle size (even smaller than a micron) and nature (including oil oxidation products).

As thousands of customers have been able to verify, the removal of all contaminants (including moisture) slows down the natural process of oil deterioration, making for a much longer service life.

Because it is precisely below the 1 micron threshold that we find the most dangerous portion of the contaminants, the so-called sludge, which is the root cause of most hydraulic system problems.

As demonstrated originally by KLEENTEK expert Dr. Sasaki in the 1990s, and is now universally acknowledged, traditional filters are one of the main causes of oil breakdown and oxidation. As it goes through a filter, in fact, the oil is electrically charged and the resulting spark discharge within the filter itself and the circuits causes the breakdown of the oil molecules and the formation of free radicals. In a KLEENTEK cleaner, the electrostatic field is carefully dimensioned, also as a function of oil flow rate, so as to ensure that the oil is not charged and damaged.
