A high efficiency coalescing filter capable of removing solids and liquids is recommended.

The purpose of this discussion is not to tip the scale toward either technology, but to address air treatment requirements in food processing applications. This means the end-user directly influences the quality of this energy source. ISO has identified two opposing inlet oil aerosols concentrations to determine the performance and pressure drop characteristics of coalescing filters.

Filter manufacturer may elect to publish performance date at either of the two inlet concentrations. 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.

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.

In total volume, condensed water vapor represents the majority of liquid contamination in a compressed air system.

ISO – Filters for compressed air — Test methods — Part 1: Oil aerosols

The challenge concentration selected shall appear in published technical data. Depending on the location of the compressor intake, oil vapor levels in industrial areas may contain ppm of airborne hydrocarbon aerosols. Compressed air systems serving the food processing industry must maintain dry, moisture free conditions mitigating the risk of micro-organism growth. Desiccant dryers- ios activated alumina- will adsorb water vapor from the air most effectively, delivering ISO In a general industrial area, there are nearly 4, airborne particles per cubic foot of air.


125001- activated carbon filter, installed in series, kso also recommended downstream of the coalescing filter. End users are given the choice of selecting from several air compressor technologies, some of which require lubrication in the compression chamber for cooling and sealing purposes, and others that operate less lubricant in the compression chamber.

Air Quality Standards ISO 8573.1 & ISO12500

However, this standard does not address how manufacturers are to test and rate the filters. The adsorption filter will remove trace odors and oil vapor to 0.

You can trust EXPEL Filters to provide you with the clean compressed air you require wherever and whenever you need it. The particulate filter will also enhance the service life of high 1250-01 coalescing filters by minimizing solid loading. The new ISO filter standard addresses this issue and establishes how manufacturers test and rate compressed air filters. High quality compressed air is critical for providing food products that are not jso cost effective to process but also safe to eat.

The ISO is designed to clear up this confusion and apply test standards to benefit air treatment manufacturers such iao EXPEL by providing the means to commercially separate filter products through certifiable performance. Lubricated compressors are typically less expensive to purchase and 122500-1 a lower cost of ownership.

At this level of dryness, bacteria will cease to grow. Filters shall be challenged by solid particulate in the range 0. 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. Air treatment manufacturers present technical data in reference to ISO The remaining oil content should be 0.

The ISO Air Quality standard is serving the industry well by raising end user awareness of how to measure and define the quality of compressed air. Spores, pollen and bacteria are less than 2 micron in size. The ISO standard is a document that provides requirements, specifications, guidelines or characteristics that can be used consistently to ensure that products, processes and services are fit for their purpose.

This compressor technology presents no risk of lubricant migrating into the process air.


Air Quality Standards ISO & ISO | Compressed Air Best Practices

The standard also determines that air quality shall be designated by the following nomenclature:. The ISO filter standard addresses this issue and establishes how manufacturers test and rate compressed air filters. When this ambient air is compressed to psig, the concentration of solid contamination will reach significant proportions.

The vital piece of information which is missing when testing products is a challenge concentration. The end user determines which compressor design best 12500-11 the desired requirements.

ISO International Standards ensure that products are safe, reliable, sio and of good quality to ensure that all our products meet and International Standards. The 12500-11 defines critical performance parameters namely, inlet oil challenge, inlet compressed air temperature and pressure measurement techniques that will deliver certifiable filter performance information suitable for comparative purposes.

Because compressed air may come in direct and indirect contact with food processing, an elevated level of filtration is required.

The playing field is not level and consumers become confused. In most cases, end users select compressed air system components by comparing technical data from various air treatment manufactures. The next time iwo sit down for dinner, take a good look at your food. Hydrocarbon vapors, the primary component of fossil fuel combustion, will condense in a piping system when cooled forming a liquid contaminant.

In pneumatic control circuits, solids particles plug control valve orifices, affect 12500–1 of gauging and score air cylinders walls, causing leaks. ISO is a multi-part standard.

Adsorption filters, utilizing an activated carbon medium, possess the polarity to attract hydrocarbon vapors from an air stream onto a porous surface. Of the primary utilities employed in the food-manufacturing environment, compressed air is the only isk generated by the end-user.

The ISO standard will continue to benefit end-users by defining air quality levels and methods to determine contaminants present in their air system.
