If you are unsure, and only know that you have to protect your system from dust, then you need to find out your air quality requirements. For some applications, such as inflating tires, some contaminants in the compressed air do not pose any problems. Others, such as applications in cleanroom environments, require the highest air purity
Knowing your air quality requirements and which standards to comply with will help you select the right air filter, which could lower your investment costs and ensure that you get the most out of your compressed air system. If you are not sure which ISO standard applies to your operation or which type of contaminant you have to protect your system from, you can contact Atlas Copco or consult the two tables below.
