Air Compressor Inline Filters

Compressed air systems continually challenge filtration with moisture, solid particulates, and liquid oil or oil vapors. All of these contaminates wreak havoc with pneumatic equipment, processes and end products costing you time and money.

Types of Air Compressor Inline Filters

Filtration comes in various grades depending on what is to be filtered out, and where in your compressed air system the filter is to be placed. The following are general filtration guidelines that should be followed to ensure clean, dry air downstream from your compressor system.

  1. Water Separator – Should be installed after the compressors aftercooler (or a stand alone aftercooler if your system has one).

  2. Separator/Filter – Can be used in place of a Water Separator (described above) or as a prefilter to a refrigerated air dryer.

  3. General Purpose Filter – Typically a 1 micron particulate prefilter for refrigerated air dryers and high efficiency oil removing filters.

  4. Dry Particulate Filter – A dry, solid particulate afterfilter for heatless desiccant dryers (to catch any desiccant particles from traveling downstream of the dryer).

  5. High Efficiency Oil Removal Filter – Can be a prefilter to desiccant and membrane dryers, or an afterfilter for refrigerated air dryers. Also works wells as a stand-alone filter for oil removal at the point-of-use of compressed air.

  6. Maximum Efficiency Oil Removal Filter – Can be used as a prefilter, in conjunction with a general purpose filter, for desiccant and membrane dryers as well as for oil-free air applications (note: oil-free is not the same as oil-less).

  7. Oil Vapor Removal Filter – Used as an afterfilter to a high efficiency liquid oil removal filter for true oil-free applications.

Air Compressor Mist Eliminator (FME Series by Gardner Denver)

Compressed air is directed through a loosely packed bed of highly engineered, water resistant glass fibers. Water droplets and oil aerosols entrained in the air stream are captured by the fibers through the mechanisms of direct interception, inertial impaction, and interception resulting from Brownian motion. The capture aerosols move along the fibers and coalesce into larger droplets that gravitate to the bottom of the housing and are discharged from the system by an optional automatic drain valve.
