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.

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.

Depending on 1200-1 location of the compressor intake, oil vapor levels in industrial areas may contain ppm of airborne hydrocarbon aerosols. In most cases, end users select compressed air system components by comparing technical data from various air treatment manufactures.

An easy to understand ISO In pneumatic control circuits, solids particles plug control valve orifices, affect accuracy of gauging and score air cylinders walls, causing leaks. 125000-1 vapor enters the system through the intake of the air compressor. The purpose of this discussion is not to tip the scale toward either technology, but to address air treatment requirements in food processing applications. The ISO test standards will benefit air treatment manufacturers by providing the means to commercially separate filter products through certifiable performance.

ISO Standards – Air Quality

The most scrutinized and often discussed contaminant classified by ISO Each is categorized and assigned a quality class ranging from class 0, the most stringent, to Class 9, the most relaxed.

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 challenge concentrations are rarely included in technical data, filter performance which may look similar or identical on paper, can provide significantly different results when installed in a compressed air system.

A high efficiency coalescing filter capable of removing solids and liquids is recommended. ISO provides guidance for the testing and methods for determining particulate filter removal efficiency, by particle size. The vital piece of information which is missing when testing products is a challenge concentration. 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. The playing field is not level and consumers have become very confused. In total volume, condensed water vapor represents the majority of liquid contamination in a compressed air system.

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. Because compressed air may come in direct and indirect contact with food processing, an elevated level of filtration is required. This filter combination will ensure specified filtration levels achieve ISO The ISO standard will continue to benefit end-users by defining air quality levels and methods to determine contaminants present in their air system.

Spores, pollen and bacteria are less than 2 micron in size. ISO International Standards ensure that products are safe, reliable, tested and of 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.

Lubricant free compressors generally have a higher initial cost and greater maintenance costs over the life cycle of the equipment. It provides power for pneumatically operated tools and equipment that renders meat products, aerates liquids and mixes granular ingredients. The challenge concentration selected shall appear in published technical data. 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.

Air Quality Standards ISO 8573.1 & ISO12500

Lubricant is only required for the bearings and timing gears, which is segregated from the compression chamber. Adsorption filters, utilizing an activated carbon medium, possess the polarity to attract hydrocarbon vapors from an air stream onto a porous surface.


The ISO filter standard addresses this issue and establishes how manufacturers test 12500-11 rate compressed air filters.

Three separate test laboratories were constructed, each equipped with stainless steel piping, state of the art instrumentation and contaminant measurement equipment. Using this, the end-user can make educated decisions as to the filtration performance 12050-1 to generate a certain quality level.

When properly treated, compressed air is regarded as a safe, clean utility, as compared to other energy sources.

Air Quality Standards ISO & ISO | Compressed Air Best Practices

You can trust EXPEL Filters to provide you with the clean isl air you require wherever and whenever you need it. ISO is a multi-part standard, with ISO encompassing the testing of coalescing filters for oil aerosol removal performance, ISO quantifies vapor removal capacity of adsorption filters, and; ISO outlines requirements to test particulate filters for solid contaminant removal.

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. High quality compressed air is critical for providing food products that are not only cost effective to process but also safe to eat.

The remaining oil content should be 0. An activated carbon filter, installed in series, is also recommended downstream of the coalescing filter. ISO determines the adsorption capacity and pressure drop of hydrocarbon vapor removal filters.

Even a well maintained and routinely changed intake filter will allow solid particles to enter the air system. Solid particulates, water and oil in both aerosol and vapor form are recognized. 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.

Air treatment manufacturers present technical data in reference to ISO
