Compressed air service unit

Maintenance units for compressed air

With proper compressed air treatment using Festo maintenance units, you can increase the service life of your components, avoid downtimes and machine failures, and significantly improve your process and product safety. Our compressed air maintenance units precisely meet the requirements your production needs: from standard applications to application-specific solutions that place the highest demands on purity, pressure and flow. Thanks to integrated monitoring functions, you will always be informed about the condition of compressed air filters and can plan needs-based maintenance. Pressure, flow and consumption are therefore always in the green range.

Festo maintenance units

Our "one MS worldwide" offers maintenance units for every need: from simple standard to application-specific solutions with the highest requirements for compressed air quality. MS-B is ideally suited for standard applications. If there are special requirements for compressed air purity, up to the high-end range, the MS series with its modular design is the ideal choice.

Depending on the application, a service unit consists of a pressure regulator, various filters, a branch module and pressurization and exhaust valves. The air preparation units ensure the correct compressed air quality, and filter compressor oil, condensate and dirt particles from the air. These are based on decades of expertise and a clear understanding of the demands of tomorrow.

Selection tool for your maintenance unit

Find the best service unit for your application: With our engineering tool, you can put together the right air preparation unit combination for you. The tool uses "typical application" parameters to produce a recommendation for the air quality class and components. Alternatively, you can specify a compressed air purity class or assemble a filter cascade directly. If you want to add any of our most popular service modules, the tool will recommend the right layout and size of the units in accordance with the required flow rate. The air preparation unit is pre-configured, which means that oversizing is a thing of the past!

To the engineering tool


The sizing of the air preparation units depends on the system's air consumption. Undersizing leads to pressure fluctuations and to reduced filter service life. For cost reasons, high quality compressed air should only be used where it is absolutely necessary. Branching modules between the individual filter stages enable the user to tap off compressed air of various qualities.
