Filtration, regulation and treatment of compressed air
Compressed air treatment is an indispensable part of the compressor system. You need to treat compressed air because it naturally has dust particles, oil and, last but not least, condensate. This combination is very damaging to any device you connect to the compressor. Corrosion, clogging and sticking of moving parts shorten the life of valves, pneumatic tools and automated line components. That's why we bring you a comprehensive air treatment program that includes air dryers, filters, pressure regulators, separators and cyclone separators. With our air treatment program , you can extend the life of your entire compressor system many times over and avoid expensive service or line downtime. More on how to filter and condition air in the sequel.

Basic principles of air treatment:
- drying - air dryers(condensation dryers, adsorption dryers, membrane dryers)
- filtration - air filters according to ISO 8573(air filtration, high pressure filters, process filters, vacuum filters)
- regulation - air pressure regulators on the distribution lines before the application itself
- getting rid of condensate and oil(cyclone separators, water-oil separation)
What to follow - Compressed air quality classes according to ISO 8573-1
How do you know what quality of compressed air to have for your application? The ISO 8573-1 standard is the guideline. The quality of the produced air is described in the standard by seven classes, from 0 to 6. Each class has a prescribed maximum content of solids, water and oil. Different purity classes are therefore required for different applications and flow rates. For example, for workshop air, the standard prescribes a quality of 4-4-5. The three numbers indicate the three prescribed quality classes in the order - solids quality class, water quality class, oil quality class. The highest demands are of course in the pharmaceutical, chemical and food industries.
We talk in detail about the quality classes in our article from the advisory board: How to filter compressed air
Step-by-step air treatment
It is best to use an air dryerbehind the compressor to ensure that the condensate is removed. It is recommended to use a pre-filter between the air dryer and the compressor. There are different requirements for artisans and different requirements in a medical environment. Therefore, the purity of the air in microns needs to be determined. This filtration is then placed behind the dryer. Finally, we can regulate the compressed air to the desired pressure (atmospheres). All the accessories that we use to treat the air will wear out over time and the filter cartridges or granulate will need to be replaced. We use clogging indicators or differential pressure gauges to measure filter wear. This accessory can only be found on better filters for compressed air treatment.
