Order LookupMain Line Compressed Air Filters
Available0 products
Main line air filters install into the primary air supply line after the air compressor, and before or after other air treatment equipment such as air dryers and aftercoolers. Particulate filters trap larger-sized particles of water and dirt while coalescing filters trap oil, and activated carbon filters trap oil vapor and odor. The size of particulate trapped in a filter is measured in microns which is specified in the filter rating.
