AN AIR FILTER, USED TO FILTER COMPRESSED AIR IN PNEUMATIC APPLICATIONS. THE FILTER USES CENTRIFUGAL MOTION TO FORCE LIQUID OUT OF THE COMPRESSED AIR. AN INTERNAL SPINNER CAUSES SPINNING MOTION. THE CONDENSATE JOINS TOGETHER ON THE WALL OF THE DEVICE. WHEN THE CONDENSATE GAINS ENOUGH MASS IT FALLS TO THE BOTTOM OF THE SEPARATOR BOWL WHERE IT POOLS IN THE SUMP UNTIL IT IS FLUSHED OUT OF THE SYSTEM BY A FLOAT DRAIN VALVE. SECONDLY THE AIR WILL BE PUSHED THROUGH A FILTER TO REMOVE THE REMAINING SOLID PARTICLES OF DUST AND DIRT. REMOVING THE CONDENSATE FROM THE COMPRESSED AIR IS CONSIDERED THE PRINCIPAL FUNCTION.
