High efficiency air filtration is a necessity to modern engine operation for peak performance and regular service life. The atmosphere contains both natural (pollen, dust, sand, etc.) and industrial (soot, abraded materials, pollutants, etc.) contaminants which can adversely affect the combustion process and cause engine damage.
Various advanced media technologies are used engine intake air filtration, including cellulous wetlaid, meltspun, drylaid, and nanofiber composites, etc.
