Compressed Air Filtration Levels

When selecting a filter the designer must consider several factors.

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. 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. Coalescing filters remove most contaminants very well reducing particulate levels down to 0 1 micron in size and liquids down to 0 01 ppm. 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.

Different applications require different levels of air cleaning effectiveness. Because compressed air may come in direct and indirect contact with food processing an elevated level of filtration is required. It is an acronym for high efficiency particulate air filter as officially defined by the u s. Compressed air filters from grainger can help trap dirt particles and other impurities that can prevent your air compressor from operating at peak performance.

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. In stock and ready to ship. Filtration removes a surprising volume of oily water from compressed air. Hepa is a type of pleated mechanical air filter.

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. Many compressed air applications can handle contamination levels well above 0 3 microns. At room temperature a filtration system designed to handle air traveling at 500 std. 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.

These filters also remove particulates from compressed air trapping them within the filter media which can lead to pressure drops if not changed regularly. It should be capable of removing solid and liquid aerosols 0 01 micron and larger. Why compressed air filtration is necessary. A high efficiency coalescing filter capable of removing solids and liquids is recommended.

Additionally the article provides an overview of the compressed air purity classes defined by iso 8573 1 2010.
