Technical characteristics

Oil filter to filter paper requirements are higher than the air filter, mainly because the temperature of the oil changes from 0 to 300 degrees, in the severe temperature change, the concentration of oil also changes accordingly, which will affect the filter flow of the oil. Quality oil filter paper should be able to filter impurities under severe temperature changes, while ensuring adequate flow.

Product action

Under normal circumstances, the various parts of the engine are lubritated by oil to achieve normal work, but the metal debris produced by the operation of the parts, the dust entered, the carbon deposit oxidized at high temperature and some water vapor will be continuously mixed into the oil, the service life of the oil will be reduced over a long time, and the normal operation of the engine may be affected when serious.

Therefore, the role of the oil filter is reflected at this time. Simply put, the function of the oil filter is mainly to filter the vast majority of impurities in the oil, keep the oil clean and extend its normal service life. In addition, the oil filter should also have strong filtering ability, low flow resistance, long service life and other performance.
