Compressed Air Filter

Dry Particulate Filters
Dry particulate filters remove dry particulate from the airstream. They may be compressor intake filters or inline compressor filters (air line filters). Dirt particles are trapped by the filter media through direct interception, inertial impact or diffusion. Large particles are directly blocked by the fibers in the filter media. Smaller particles are intercepted as they move erratically through the media via Brownian motion (diffusion). These particles are held in the media through electrostatic attraction.

Coalescing Inline Filter
A coalescing filter is another type of inline air compressor filter. An oil coalescing air filter is a type of air line filter that removes both oil mists or oil vapors and dry particulates. A coalescing filter works by trapping mists and aerosols in layers of fine mesh. Aerosolized oil particles and water droplets collect on the surface of filter media and coalesce into larger and larger droplets until they are heavy enough to fall. Liquid is collected at the bottom of the filter and drained away. Fine particulates fall out with the liquid, while coarser particles remain trapped in the filter media.

Adsorption Filters
An adsorption air compressor filter is used to trap vapors, gaseous contaminants, chemical fumes and odors. These filters are used for high-purity applications that require the removal of trace gases and vapors along with sub-micron particulates. Activated carbon is the most common material used for adsorption.

Air Compressor Oil Filters
Oil filters are used for oil-lubricated industrial air compressors, such as oil-injected rotary screw compressors. They remove dirt, rust and other coarse contaminants from liquid oil as it circulates through the compressor. This protects the compressor from wear and tear on bearings and other lubricated parts. An air compressor oil filter is similar to the oil filter you might find on your car or lawnmower.
