Selecting compressed air purification

Published:  09 August, 2018

The international standard for compressed air quality, ISO 8573:2010, is the primary documentation to facilitate compressed air systems component selection, design and performance measures. Hi-line Industries, UK manufacturer of high-quality compressed air purification equipment reports it has been working closely with the British Compressed Air Society to produce a best practice guide for the filtration and drying of compressed air.

The ISO standard introduces a simple system of classification for the three main contaminants present in any compressed air system – particulate, water and oil. Whenever the purity of air required is specified then the standard must be referenced and then the class for each contaminant is simply listed in turn.

For example, compressed air to quality class 2.2.2 would be equivalent to a maximum particle size of 1 micron for solid contaminants, a pressure dewpoint of -40°C or lower and 0.1mg per cubic metre of compressed air of oil content filtration.

Hi-line Industries says it provides a wide range of energy efficient compressed air equipment to meet ISO standards including compressed air dryers, nitrogen and oxygen generators, filtration equipment, condensate systems, heat regenerative adsorption dryers, membrane dryers, drains and service kits.All equipment is designed and built to the highest standards and quality and suitable for use in a broad range of industries ranging from food, beverage, pharmaceutical, medical, dairy, automotive, electronics and breathing air, through to general manufacturing and engineering requirements.
