The inside of the oil filter creates a strong high-temperature permanent magnetic field. During high-temperature and high-speed operation, engines naturally produce metal particles. Iron particles are extremely hard; if they circulate with the oil, they can enter critical engine components and increase wear. Magnetic technology helps capture these particles before they cause damage. Adsorption force: Utilizes niobium alloy magnetic steel to generate a powerful magnetic field that firmly captures small iron filings produced by the engine, preventing them from re-entering the system. Extend engine life: Oil filtered through the magnetic system contains fewer impurities, resulting in smoother performance and reduced frictional resistance. This contributes to quieter and smoother engine operation. Purification oil: The oil filter magnet captures iron particles and other harmful solid contaminants. Even beyond regular maintenance intervals, oil remains cleaner and more effective. Reduce consumption, more environmentally friendly: Helps reduce engine wear by up to 90%, significantly lowering the rate of wear. While maintaining engine performance, it also supports environmental protection by improving efficiency.
