The challenge concentration selected shall appear in published technical data.
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. The standard defines critical performance parameters namely, inlet oil challenge, inlet compressed air temperature and pressure measurement techniques that will deliver certifiable iiso performance information suitable for comparative purposes.
Adsorption filters, utilizing an activated carbon medium, possess the polarity to attract hydrocarbon vapors from an air stream onto a porous surface.
ISO does not however address how manufacturers are to test and rate the filters they produce. 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 ISO is designed to clear up this confusion and apply test standards to benefit air treatment manufacturers such as EXPEL by providing the means to commercially separate filter products through certifiable performance.
Air treatment manufacturers present technical data in reference to ISO The purpose of this discussion is not to tip the scale toward either technology, but to address air treatment requirements in food processing applications. Lubricated compressors are typically less expensive to purchase and have a lower cost of ownership. Using 12500-1, the end-user can make educated decisions as to the iiso performance required 122500-1 generate a certain quality level. Both air compressor technologies are subject to the inherent challenges presented by quality of the intake air.
Desiccant dryers- using activated alumina- will adsorb water vapor from the air most effectively, delivering ISO Because compressed air may come in direct and indirect contact with food processing, an elevated level of filtration is required.
Filters shall be challenged by solid particulate in the range 0. Ingested oso in the form of water vapor, solid particulate and hydrocarbon vapor must be addressed regardless if the compressor is lubricated or free from lubricant. 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.
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. The next time you sit down for dinner, take a good look at your food. ISO has identified two opposing inlet oil aerosols concentrations to determine the performance and pressure drop characteristics of coalescing filters. ISO is a multi-part standard. You can trust EXPEL Filters to provide you with the clean compressed air you require wherever and whenever you need it.
The adsorption process will continue until the activated carbon media is fully consumed.
A high efficiency coalescing filter capable of removing solids and liquids is recommended. 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.
An activated carbon filter, installed in series, is also recommended downstream of the coalescing filter. Compressed provides the energy source for pneumatic conveyers that transport liquids, powders and moisture sensitive product throughout the plant.
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.
ISO Standards – Air Quality
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. It is ultimately used to package, wrap, seal, palletize and label food products prior to storage or shipment. Not all products claiming compliance with the ISO standards are tested in the same way. Solid particulates, water and oil in both aerosol and vapor form are recognized.
ISO Standards – 12500 Air Quality
ISO Iiso Standards ensure that products are safe, reliable, tested and of good 12500–1 to ensure that all our products meet and International Standards. The particulate filter will also enhance the service life of high performance coalescing filters by minimizing solid loading.
Even a well maintained and routinely changed intake filter will allow solid particles to enter the air system. Each is categorized and assigned a quality class ranging from class 0, the most stringent, to Class 9, the most relaxed.

Motion Industries Names New President. The standard also determines that air quality shall be designated by the following nomenclature:.
Using this, the end-user can make educated decisions as to the filtration performance required to generate a certain quality level.
