In many respects, standards are the foundations that underpin all industrial operations. They create a level playing field that ensures fair competition, while reducing risk and enhancing safety, efficiency and innovation. They also provide the frameworks that help manufacturers develop reliable production processes, with accepted parameters against which performance, reliability and quality can be measured.

For industrial users of compressed air, one of the key standards is ISO 8573. This defines the nature and permissible concentration of contaminants in a compressed air stream. Note that ISO 8573 does not include breathing or medical air; these are covered in separate BS EN 12021 standards and various HTM (Health Technical Memoranda) guidelines.

ISO 8573 was originally introduced in 1991 and has subsequently been updated on a number of occasions; the latest version is ISO 8573:2017. As the International Standards Organisation (ISO) tends to reappraise standards every five years, we should be due for a review in 2022.

The current version of the standards consists of nine parts, with the Part 1 relating to the types of contaminants and different levels, or classes, of purity, while the remaining eight parts cover various test methods and instruments. In full, these are:

For each Group, the standard then categorises different Quality Classes, each with a maximum permissible concentration of contaminants. For example, for Group B, there are 9 Quality Classes, ranging from Class 1, which is the most stringent, to Class 9, the most basic, while for Group A there are seven Classes and for Group C five Classes. These are shown below:

It is normal for equipment to be specified in line with these categories. For example, a compressed air filter might offer performance to ISO 8573:2010 Class 1-2-2; i.e. it conforms to Class 1 for particulate filtration, Class 2 for moisture removal and Class 2 for oil filtration.

Note that in each Group there is a Class 0. This is normally based on an agreed specification between the user and equipment supplier and is set at a level that is suitable for the application and that can be validated using the relevant test criteria stipulated in ISO 8573 Parts 2 to 9.

Note also that Group A does not include microorganisms, although testing for the presence of these contaminants is defined under Part 7 of the ISO 8573 standard. In applications such as food and beverage, where microbiological contamination needs to be controlled, the normal approach is to define safe criteria based on the demands of the application itself. This can then be controlled by using precise dew-point measurement and air drying, to the level where the growth of microorganisms is inhibited, followed by specialised sterile point-of-use filtration.

A final, but equally important point, is that the standard can help to minimise energy costs. By having a clear understanding of the exact requirement for the maximum acceptable levels of contamination, especially moisture, it is possible to optimise the performance of systems components such as dryers without affecting air or final product quality.

The International Standards Organization (ISO) created ISO 8573-1 to measure compressed air quality by the amount of solid particulates, water, and oil content in one cubic foot of compressed air. This standard outlines the levels of solid particulates, water, and oil allowed based on the classification.

Oil-free air compressors provide manufacturers with peace of mind by avoiding contamination risks from trace oil reaching their product and protecting their corporate reputation. This peace of mind continues further downstream by preventing oil contamination in pneumatic equipment lines leading to higher maintenance and downtime.

Oil-flooded air compressors generate oil-contaminated condensate that is often regulated by governing authorities for disposal. This hidden cost of monitoring, testing, and disposing of condensate is eliminated with the use of oil-free air.

The more energy efficient the compressor, the more direct impact the machine will have on lowering operating expenses. Oil-free compressors are typically 10-15% more efficient than equivalent capacity oil-flooded rotary machines. Subsequently, since energy costs are generally 60-75% of the total life-cycle costs of an air compressor, overall cost savings from efficiency alone can result in several thousands of dollars in life-cycle savings.

Oil-flooded machines also require several oil filters and oil separators in the air path to clean the manufactured compressed air. Each one of these items will cause a pressure drop across the filter, resulting in lower air pressure delivery downstream in the plant. The decrease in pressure means the compressor must work harder to maintain the demand needed for the plant creating lower efficiencies and higher energy costs.

Understanding the long-term benefits an oil-free air compressor brings to manufacturing, FS-Elliott is committed to only designing air compressors that deliver 100% guaranteed oil-free, ISO 8573-1 Class 0 air.

ISO 8573 is an international standard in the United States, United Kingdom, Germany and India that defines contaminants found within compressed air. It is known as the guideline to understand air purity levels within a compressed air system.

The standard is divided into nine different parts. 8573-1 defines air quality classes based upon specific contaminant types to allow users to determine the appropriate purity levels for any given application. 8573-2 through 9 outline methods to test and quantify an air sample to determine which purity class it falls into. ISO 8573-1 is the most frequently used aspect of ISO 8573, and we will explain it in more depth throughout this blog.

The ISO 8573 group of International Standards is used to classify compressed air quality by describing its contaminants. It also provides test methods and analytical techniques for each type of contaminant.

A compressed air purity classification is achieved by installing specific compressed air treatment equipment. Depending on the use of a compressed air system, the air quality may have to be validated in accordance with the necessary quality class as defined by ISO 8573-1.

The table below demonstrates the purity classes used by ISO 8573-1 to classify compressed air quality. The purity classes define the maximum amount of contaminants that may exist in the air stream.

The ISO 8573-1 standard is split up into three groups, based on the type of contaminants: solid particulates, water (liquid and vapour) and oil (aerosols and vapour). Within each category, there are multiple purity classifications. It is crucial to understand the lower the number, the purer the air needs to be.

Although it is not a legal requirement to meet ISO standards, it ensures you are installing the right compressed air treatment equipment to produce high-quality end products. If the quality of your compressed air does not meet the necessary standards set by ISO 8573-1, there is a chance that damage will occur to your equipment and end product.

for compressed air treatment equipment that is ISO 8573-1 certified, it is essential to understand the classifications. This image shows an example that indicates the filter is Class 1 for particles, Class 2 for water and Class 1 for oil.

Within each of these three categories, there are different classifications for each contaminant. The lower the number in each category, the higher the purity and the cleaner the air needs to be. For example, within the particles category (see table above), class 5 air can have a maximum of 100,000 particles per cubic metre whereas, class 4 air can only have a maximum of 10,000 particles per cubic metre. Therefore, class 5 air can contain more particles than class 4.

The example below illustrates how filtration is used to accommodate an average quality level. The system is designed to remove bulk liquid and high concentrations of oils, which may contain burnt by-products such as lacquers. The classification shows that this will remove Class 3 particles and Class 4 oil.

The second example below demonstrates a much higher-quality air system. This package provides the user with the best possible compressed air quality. In some cases, specific equipment required to achieve a given air purity class must itself be protected with additional air treatment equipment. For example, the dryer is necessary to meet water content class 2, but it must be protected by a water separator and high-efficiency filter in order to do so efficiently. The classification of this package demonstrates that it removes Class 1 particles, Class 2 water and Class 1 oil.
