Using this, the end-user can make educated decisions as to the filtration performance required to generate a certain quality level. To achieve the recommended ISO Filter manufacturer may elect to publish performance date at either of the two inlet concentrations. This may seem like a lot of particulate matter, but keep in mind, a solid particle 40 um in size is barely visible to the naked eye.

This means the end-user directly influences the quality of this energy source. Because compressed air may come in direct and indirect contact with food processing, an elevated level of filtration is required. We all benefit, appreciating that ISO, a global international standards organization, continues to refine its standards for the betterment of the compressed air industry and private sector.

Jul 14, Original Stories 0 Comments. You can trust EXPEL Filters to provide you with the clean compressed air you require wherever and whenever you need it.

The most scrutinized and often discussed contaminant classified by ISO Solid particulate must be removed from process air serving the food industry. The vital piece of information which is missing when testing products is a challenge concentration. The playing field is not level and consumers become confused. The adsorption process will continue until the activated carbon media is fully consumed. The standard also determines that air quality shall be designated by the following nomenclature:.

Air Quality Standards ISO 8573.1 & ISO12500

In total volume, condensed water vapor represents the majority of liquid contamination in a compressed air system. When properly treated, compressed air is regarded as a safe, clean utility, as compared to other energy sources. This moisture will spoil food products, cause pneumatic machinery failure and promote bacterial growth in the compressed air piping. Since compressed air used in food processing operations may come in direct contact with the food, a compressed air dryer producing a sub-zero pressure dew point is required.


The ISO is designed to clear up this confusion and apply test standards to benefit air treatment manufacturers such as EXPEL by 15200-1 the means to commercially separate filter products through certifiable performance.

ISO does not however address how manufacturers are to test and rate the filters they produce. So even though different manufacturers claim their products meet a certain purity class, they will most likely have been tested with differing concentrations of contamination entering the product and as 125500-1 concentrations are rarely included in technical data, filter isso which may look similar or identical on paper, can provide significantly different results when installed in a compressed air system.

The remaining oil content should be 0. A well maintained scfm lubricated air compressor, with a 1500-1 4 parts per million carry-over, will add up to 4. The ISO standard is a document that provides requirements, specifications, guidelines or characteristics that can be used consistently to ensure that isoo, processes and services are fit for their purpose. ISO has identified two opposing inlet oil aerosols concentrations to determine the performance and pressure drop characteristics of coalescing filters.

Particles may restrict flow through air jet nozzles used to clean food preparation surfaces or adversely affect the consistency of spray coatings applied on food products.

Three separate test laboratories were constructed, each equipped iwo stainless steel piping, state of the art instrumentation and contaminant measurement equipment.

Filters shall be challenged by solid particulate in the range 0. Hydrocarbon vapors, the primary component of fossil fuel combustion, will condense in a piping system when cooled forming a liquid contaminant. The particulate filter will also enhance the service life of high performance coalescing filters by minimizing solid loading.


Motion Industries Names New President. Air treatment manufacturers present technical data in reference to ISO Compressed air systems serving the food processing industry must maintain dry, moisture free conditions mitigating the risk of micro-organism growth. Using this, the end-user can 12500–1 educated decisions as to the filtration performance required to io a certain quality level. Both air compressor technologies are subject to the inherent challenges presented by quality of the intake air.

At this level of dryness, bacteria will cease to grow. An activated carbon filter, installed in series, is also recommended downstream of the coalescing filter. The challenge concentration selected shall appear in published 12050-1 data.

Air Quality Standards ISO & ISO | Compressed Air Best Practices

ISO – Testing of filters for oil aerosol removal performance ISO — Testing quantifies vapour removal capacity of adsorption filters ISO — Testing for solid contaminant removal ISO — Testing of water-removal efficiency and operational pressure drop You can trust EXPEL Filters to provide you with the clean compressed air you require wherever and whenever you need it.

The ISO standard will continue to benefit end-users by defining air quality levels and methods to determine contaminants present in their 12050-1 system. Water vapor enters the system through the intake of the air compressor. Food processors maintain a social responsibility for upholding the quality of their products and that accountability begins with the selection of compressed air system components.

This compressor technology presents no risk of lubricant migrating into the process air. An easy to understand ISO Desiccant dryers- using activated alumina- will adsorb water vapor from the air most effectively, delivering ISO Lubricated 12500-11 are typically less expensive to purchase and have isp lower cost of ownership.
