Spores, pollen and bacteria are less than 2 micron in size. The standard defines critical performance parameters namely, inlet oil challenge, inlet compressed air temperature iao pressure measurement techniques that will deliver certifiable filter performance information suitable for comparative purposes. Presenting product data in this way should allow users to easily compare the performance of purification products from different manufacturers and cost effectively meets the air quality requirements of their application.

The older 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 used. Both air compressor technologies are subject to the inherent challenges presented by quality of the intake air.

Air treatment manufacturers present technical data in reference to ISO The particulate filter will also enhance the service life of high performance coalescing filters by minimizing solid loading. ISO International Standards ensure that products are safe, reliable, tested and isi good quality to ensure that all our products meet and International Standards.

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. 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.


Jul 14, Original Stories 0 Comments. The playing field is not level and consumers become confused. High quality compressed air is critical for providing food products that are not only cost effective to 122500-1 but also isi to eat.

Air Quality Standards ISO 8573.1 & ISO12500

The ISO air quality standards and ISO compressed air filter standards make the basis for air treatment product selection much easier. Ingested contamination in the form of water vapor, solid particulate and hydrocarbon vapor must be addressed regardless if the compressor is lubricated or free from lubricant. An activated carbon filter, installed in series, is also recommended downstream of the coalescing filter.

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.

ISO Standards – 12500 Air Quality

Lubricant free compressors generally have a higher initial cost and greater maintenance costs over the life cycle of the equipment. The ISO filter standard addresses this issue and establishes how manufacturers test and rate compressed air filters.

ISO provides guidance for the testing and methods for determining particulate filter removal efficiency, by particle size. Using this, the end-user can make educated decisions as to the filtration performance required to generate a certain quality level. In total volume, condensed water vapor represents 1200-1 majority of liquid contamination in a compressed air system.

Compressed air is a vital energy source and is utilized in multiple operations in a food processing facility. An easy 122500-1 understand ISO A high efficiency coalescing filter capable of removing solids and liquids is recommended.


Using this, the end-user can make educated decisions as to the filtration performance required to generate a certain quality isk. When this ambient air is compressed to psig, the concentration of solid contamination will reach significant proportions.

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

Uso air systems serving the food processing industry must maintain dry, moisture free conditions mitigating the risk of micro-organism growth. When properly treated, compressed air is regarded as a safe, clean utility, as iiso to other energy sources.

The standard also determines that air quality shall be designated by the following nomenclature:. 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. 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.

Filters shall be challenged by solid particulate in the range 0. At this level of dryness, bacteria will cease to grow. Lubricated compressors are typically less expensive to purchase and have a lower cost of ownership.

This compressor technology presents no risk of lubricant migrating into the process air. Not all products claiming compliance with the ISO standards are tested in the same way. ISO does not however address how manufacturers are to test and rate the filters they produce.
