Air Filter refers to the Air Filter device, generally used for clean workshop, clean workshop, laboratory and clean room, or used for electronic machinery communication equipment and other dust prevention.There are primary filters，medium efficiency filter,high efficiency filters.All filters work the same way.Understanding its rationale can help us better understand the filters.
Compressed air from the air source contains excessive moisture and oil droplets, as well as solid impurities such as rust, sand, and pipe sealant, which can damage piston seal rings, clog small vents on components, and shorten or invalidate the component's service life.The purpose of an air filter is to separate liquid water and oil droplets from the compressed air and to filter out dust and solid impurities, but not the gaseous water and oil.
The structure of the air filter from the inlet flow of compressed air, guide plate was introduced, on the guide plate has a uniform distribution of similar fan blade helical, forcing high-speed flow of compressed air along the tangent direction of the tooth to the rotation of the strong, mixed liquid water in the air, oil, and the larger impurities in powerful under the action of centrifugal force, to the glass on the inner wall of the flow to the bottom of the cup.The compressed air is removed from the liquid water, oil and large impurities, and further filtered through the filter element to remove the tiny solid particles, and then the clean compressed air is exported from the outlet.The umbrella-shaped baffle separates the cup into two parts, and the lower part keeps the pressure static zone, which can prevent the high-speed rotating air from sucking up the water and oil at the bottom of the cup.The accumulated oil and water at the bottom of the cup is discharged from the drain valve.The air filter must be mounted vertically down the water cup.
