Compressed Air Filtration Levels

A compressed air filter can also remove moisture helping to provide better compressor air flow and improve air pressure for auto painting and machinery maintenance jobs.

Compressed air filtration levels.

It is an acronym for high efficiency particulate air filter as officially defined by the u s. Why compressed air filtration is necessary. A high efficiency coalescing filter capable of removing solids and liquids is recommended. Choose from our selection of compressed air filters including over 1 000 products in a wide range of styles and sizes.

This type of air filter can theoretically remove at least 99 97 of dust pollen mold bacteria and any airborne particles with a size of 0 3 microns µm. Ft 3 min from an air compressor operating at 100 psi will might handle about 30 gallons of condensed water every 8 hours notes the compressed air and gas handbook. It should be capable of removing solid and liquid aerosols 0 01 micron and larger. Many compressed air applications can handle contamination levels well above 0 3 microns.

Most fine particle tests use 0 3 micron as the standard to measure liquid or solid particle filtration. Pleated filters generally have higher efficiencies and lower pressure drops than panel filters which is why they are used in larger capacity units such as blower coils and high performance fan coils. Coalescing filters remove most contaminants very well reducing particulate levels down to 0 1 micron in size and liquids down to 0 01 ppm. One cubic foot of compressed air can contain millions of dirt particles considerable amounts of water and oil and even heavy metals like lead cadmium and mercury.

At room temperature a filtration system designed to handle air traveling at 500 std. When selecting a filter the designer must consider several factors. Compressed air utilized for pneumatic purposes can oftentimes be supported by a standard dry particulate filter that provides filtration down to 1 or 0 01 micron however if your process requires an osha approval and elimination of oil vapors then a charcoal activated filter will have to be utilized. Different applications require different levels of air cleaning effectiveness.

Hepa is a type of pleated mechanical air filter. If a filter tested on this particle size proves to be 100 efficient then it s fairly safe to say this filter can remove any particle above this size. Compressed air filters from grainger can help trap dirt particles and other impurities that can prevent your air compressor from operating at peak performance. Because compressed air may come in direct and indirect contact with food processing an elevated level of filtration is required.
