A Dual Stage Compressed Air Filter; the first stage is an elongated centrifugal passage that spins the air and separates the liquids from it. This centrifugal passage has the unique ability to remove extremely high amounts of bulk liquids and to maintain separation efficiency throughout its full operating flow range. The second stage is a high efficiency coalescing element that removes sub-micron oil and water aerosols down to .03 microns and dirt particles as fine as 3 microns.
