What Air Quality Class do you need for your application?

Recently we have been carrying out extensive works to improve the air quality on a customer premises. We thought it might be a good idea to relook at ISO8573-1 air quality and what it means.

Different applications require different compressed air quality levels to deliver optimal safety and efficiency. The International Organization for Standardization (ISO) maintains a set of guidelines called ISO 8573. This defines the classes of compressed air quality based on specific testing criteria.

The ISO standard classifies compressed air quality under ISO 8573 and provides standard criteria for testing air contaminants, including solid particles, oil, and water. While the ISO does not classify gasses and other pollutants like microbiological contaminants and volatile organic compounds, it does include methods for measuring such pollutants. The ISO standards are periodically updated to keep up with fast-changing industries. The most recent update was ISO 8573:1:2010.

SO8573-1 is the primary document used from the ISO8573 series as it is this document which specifies the amount of contamination allowed in each cubic metre of compressed air. ISO8573-1 lists the main contaminants as Solid Particulate, Water and Oil by three-digits, such as 1.1.1, 1.2.1, or -.8.-. The digits are read from left to right, with the first digit representing solids particles, the second water, and the third oil. A low number means air with fewer contaminants, while a high number means highly-polluted air.

Please see the picture which is Compressed Air Purity Levels shown within ISO8573-1 in tabular form.

What ISO8573 does not do, is define air quality levels per type of application. Air4u Group have solutions that can help you meet the right class for your application. Our team of air understands that every application requires a unique air system solution to provide the ideal class of air.

Air4u Group provides a complete solution, whether you are purchasing a new air system for installation or have an old air system that requires updating or professional diagnosis and repair.
