Designed to extend the life of pneumatic tools by filtering out water, oil aerosols and dirt particulates from air lines, the CleanAir product line offers three types of filtering units: centrifugal filter-regulator units, which filter out water and oil aerosols and dirt particles up to 5 microns; coalescer filter-regulator units, which remove water, dirt and oil from the system down to 0.01 micron; and three-stage desiccant units, which offer particulate removal to 5 microns, 0.01 micron, and water vapor filtering to a dewpoint of -40°F (-40°C).
