KLEANOIL engine oil filter partner (engine oil filter scrap iron adsorption device) can be widely used for engine oil filter of automobiles, airplanes, ships and engineering machinery. This product uses super-powerful magnetic materials and has the features of high temperature resistant, permanent magnetism and no diffusion of magnetism after using the collected magnetic force field and other technologies. Technical conditions: The oil filter now used in engine generally consists of filter shell and filtering core, and filtering core uses filter paper as filtering media. This filtering manner can effectively remove large-size impurities, but it is incapable of filtering and purifying the iron powder below 13.6um. The high-speed running generator will generate many scrap iron from time to time, 40% of which cannot be filtered away, the scrap iron left will enter into engine with cycle of engine oil, scratch wall of cylinder, damage inside parts and enlarge the inside clearance of engine, therefore it will reduce power of engine, increase oil consumption and finally have to take an overhaul. This device can stop scrape iron to enter engine again to cause damage on inside wall of engine, reduce the resistance inside engine, strengthen power output of engine and reduce oil consumption. KLEANOIL engine oil filter partner (engine oil filter scrap iron adsorption device) fixes five-group square magnetic on the same side surface of each link of chain, the area of link is larger than area of magnet, holding magnetic force line and preventing it to leak. The folding edge in the link side can also block off magnetic force line. When one side of magnetic column is fixed on the surface of link, two neighboring magnetic poles will form super-powerful magnetic field, which can effectively 1.3 um metallic particulates in engine oil, and the metallic particulates filtered is 12 um less than that filtered by traditional filters. It is shown in experiments that the filtration rate is up to 99.8%. For proper Use of chain structure, this device can be used for various engine filters. After two or three years of driving, the power of many cars has a remarkable reduction, but if you install this device on these cars, their power is nearly same as new car.
