The high efficiency oil remover is to remove the water, oil and impurities of the large particles through the cyclone separation Compressed air, and then filter core to remove small oil to achieve the oil removal effect. At the same time, the filter element is prevented from being blocked by large particles in the Compressed air, and the pressure loss is reduced. The service life of the filter element and the filtering accuracy are prolonged. Usually configured in the adsorption dryer front end and the oil requirements of the relatively low equipment. Cyclone separation, pre-filtration and fine filtration are integrated into a three-stage purification system. Cut The oil right out of the Compressed air. Through cyclone separation, gravity sedimentation, coarse filter core and fine filter core layer filtration, thoroughly remove oil, water and dust in the Compressed air, improve the filtering precision of the treated filter core.
