The kleenoil Filter Cartridges are made of densely wound pure coniferous long fiber wood pulp paper and manufactured by kleenoil UK itself. The filter cartridges act both by “Absorption and Adsorption” in a continuous recycling process.
The long fiber of the paper attracts the water formed either through the combustion process or by condensation and absorb it like a sponge, at the same time rejecting the large oil molecules, which are forced to pass between the tight winding of the cartridges.
As the oil passes through the cartridge, minute carbon, wear metals and silicon are extracted from the oil by adhering to any of the surfaces of the filter – a process known as adsorption.
The filter cartridge has an additional “Polypropylene disc” at the bottom to remove any particle that may pass through- offering a second stage of filtration.
