With uses for compressed air growing every day, there is a diverse variation in air quality requirements. The concentration of airborne contaminants during the compression process means the compressed air will inevitably need some form of air treatment before the point of use.
With a wide range of downstream equipment available to satisfy the most demanding compressed air treatment needs, selecting the right equipment can feel like a complex task. And these decisions will affect everything from maintenance schedules to the on-going costs associated with achieving the required air quality standards.
In this blog, we provide an overview on specifying air treatment equipment, and the range of technologies available.

The first step should be to define the precise compressed air purity requirements, ideally using the ISO 8573-1 standard, which is an internationally recognised standard detailing contaminants in compressed air and defining purity classes for them.
It is recommended that compressed air is treated:
Purification equipment should ideally be installed where the air is at the lowest possible temperature, i.e. downstream of air receivers. Point-of-use purification equipment should also be installed as close as possible to the application.
To allow correct sizing and selection of downstream equipment, the following operating parameters must be identified:
Together, these can have a major influence on product sizing and performance.
For each air treatment technology, there will be a variety of questions to ask. For example, when choosing filtration, you will need to check:
There are a wide range of purification technologies found in a typical compressed air treatment system. These include:
