　　　Air filterUsually the compressed air flowing from the inlet is introduced into the deflector. The deflector has evenly distributed helical teeth similar to fan blades, forcing the high-speed compressed air to rotate strongly along the tangential direction of the teeth, and mixed in the air The liquid water, oil and larger impurities in the water are separated under the action of strong centrifugal force and flow to the bottom of the water cup. The compressed air that removes liquid water, oil and larger impurities is further filtered by the filter element to remove tiny solid particles, and then the clean compressed air is output from the outlet.Air filterThe umbrella-shaped water baffle divides the water cup into upper and lower parts, and the lower part maintains a pressure static zone, which can prevent the high-speed rotating airflow from sucking up the water and oil at the bottom of the cup. The water and oil collected at the bottom of the cup are drained from the drain valve. The air filter must be installed vertically with the water cup down. The diameter of the upper orifice is too large, and the volume of the float required must also be large, which will increase the structural size of the water cup; if the diameter is too small, it will be difficult to make it during injection molding. In general, the diameter of the upper orifice is 0.8 to 1.5mm.

The water cup of the air filter is generally made of transparent polycarbonate (PC) material, which is convenient for observing the water level in the cup. The thickness of the water cup should be greater than 3mm, and the thickness used for the higher the pressure. Because PCs are fragile, they are generally used in larger sizes.Air filterWhen using, to add metal protective cover. When adding the protective cover, the protective cover should hold the bottom of the water cup to let the protective cover bear the main pressure. Metal cups can be used at high pressure, but a transparent scale should be used to display the water level. Different filter elements can be used according to the needs of filtration accuracy.Air filterThe filter element has 3 kinds of metal mesh type, sintering type and fiber condensation type. Metal mesh type filtration precision is low, fiber coagulation type filtration precision is high. Commonly used sintering type and copper bead sintering, resin sintering and ceramic sintering 3 categories, of which copper bead sintering common. By selecting different diameters of copper beads, different filtration accuracy can be achieved. Generally, there are 5 m,20 m,50 m,100 m 4 kinds of filtration accuracy. After free molecules contact with living carbon, they are condensed into liquid in the micropores due to the capillary principle, and some of them are integrated with the material. Adsorption without significant chemical reaction is called physical adsorption. There are a large number of invisible micropores in the living carbon material, which has a large adsorption area. In the live carbon of the size of a grain of rice, the area of the micropores is more than ten square meters.
