Oil filter; is designed to keep away contaminant particles from the engine and transmission. Particles, dirt and dust which sources from the erosion can be easily mixed with the oil during the engine start. A part of these foreign bodies are hold by the oil filter and the magnet. Moreover, tiny particles are filtered before their entrance to be able to prevent any damages to the oil system. In situation where it is not prevented from the damages, the performance of the engine falls while use of fuel increases. The circulation is needed in required quantity and speed circulation is needed to be able to get high efficiency from the engine performance. The oil filter and the filtration element is important when the subject is the circulation of oil. In addition to that, it needs to be paid attention to the use of convenient oil in terms of the engine type and the convenient filter in terms of the use of oil, in the sense of operating time of the filter and the engine. GFT filter provides customer satisfaction by producing its oil filter convenient for the engine and the oil. The advantages of using the GFT Oil filters: High safety, efficiency in the strict and the broad sense and ideal performance duration It provides lubrication to the moving parts of the engine. It provides clean filtered required oil which reduces the friction. The proofing features materials such as carbon and metal particles which sources from combustion, friction and pressure. Oil filters are usable in vehicles such as; heavy duty oil machines, commercial cars, mine machinery, agricultural machinery, automobiles, generators, compressors.
