Compressed Air Treatment
If you want to ensure a high level of process reliability and the availability of your machines, you must plan for proper compressed air treatment from the very beginning when designing the system. This is because supplying clean compressed air—free of particles, water, or oil—helps prevent malfunctions in pneumatic components, extends the service life of components, and reduces the number of machine failures and downtime. Festo offers systems that ensure compressed air purity in accordance with ISO 85731:20110.
Compressed Air Treatment – Systems from Festo
Our compressed air treatment units form the basis of our compressed air treatment solutions. They ensure the proper quality of compressed air and filter compressor oil, condensate, and dirt particles out of the air. Depending on the application, the air treatment unit consists of a pressure regulator, various filters, a manifold module, and shut-off valves. Various combinations are available from Festo. In addition, air treatment units can be individually configured within the MS modular system.
Air preparation units
The Festo product range also includes corresponding filter regulators, compressed air filters, lubricators, and pressure regulators. We also offer shut-off valves and pressure-boosting valves, compressed air dryers, compressed air distributors, and pressure boosters. Our compressed air treatment system is complemented by condensate drains, pressure gauges, and a wide range of accessories.

Why is compressed air treatment necessary?
Untreated compressed air contains contaminants such as particles, water, and oil. Water and oil can be present in both liquid and gaseous forms or can change from one form to another within the compressed air network. All three contaminants are not present in their pure form in a real compressed air system, but rather form a mixture. This mixture can vary significantly at different points in the system at different times. For example, water may accumulate in branch lines, or particles may settle in dead space over a long period of time and then be swept away all at once by a pressure surge.
One cubic meter of produced compressed air contains millions of dirt particles, significant amounts of water and oil, and even heavy metals such as lead, cadmium, and mercury. If these are not filtered out, the proper functioning of system components cannot be guaranteed in the long term. In addition, these contaminants significantly affect product quality. Therefore, proper compressed air treatment is essential for reducing machine failures and downtime, as well as for ensuring process and product safety.
Poorly treated compressed air leads to malfunctions such as:
• Rapid wear of seals
• Failure of oil valves in control systems
• Contamination of silencers
• Possible effects on the user and the machine:
• Reduced machine availability
• Higher electricity costs due to leaks
• Higher maintenance costs
• Shorter service life of components and systems
How clean should compressed air be?
Compressed air must always be clean enough to prevent malfunctions or damage. Since every filter also creates flow resistance, compressed air must be as clean as is economically necessary. Therefore, the wide range of applications for compressed air places very different demands on the quality of compressed air. If high-quality compressed air is required, it should be filtered in several stages.
ISO 8573 specifies how clean compressed air must be. This designation refers to a group of international standards regarding purity requirements for compressed air and specifies the maximum content of particulates, water, and oil that compressed air may contain in defined classes. This standard has been mandatory for pneumatic automation systems since 2010. For this reason, the various parameters are crucial for compliance with standards and for the energy-efficient treatment of compressed air. Festo compressed air treatment units and filters ensure trouble-free operation. You can find out which standard your application must comply with by contacting our managers.
