Compressed air preparation
Maintenance unit combinations
Festo maintenance unit combinations consolidate multiple conditioning stages, filters, regulators, lubricators, and optional shut-off valves, into a single pre-configured assembly. The MSB series (MSB4, MSB6) are available as ready-made combination blocks with a fixed functional scope, reducing installation and pipework effort compared to stacking individual modules. Port sizes range from G 1/8 to G 1/2; the configuration suffixes (FRC1, FRC5 to FRC12) identify the specific functional combination.
Weatherproof variants (WP) are intended for outdoor use or areas subject to elevated moisture and contamination. Electromagnetically actuated shut-off variants (suffix J, C, A, F) allow the compressed air supply to be switched via PLC or safety controller.

How to choose Maintenance unit combinations
What matters when choosing: properties, comparison and typical applications.
Technical features
MSB configuration variants
| Configuration | Functions | Port |
|---|---|---|
| MSB4-1/4-FRC5:J1M1 | Filter regulator + shut-off valve + manual drain | G 1/4 |
| MSB4-1/4-FRC6:J2M1 | Filter + regulator + lubricator + shut-off valve | G 1/4 |
| MSB4-1/4-FRC7:J3M1 | Extended combination block with additional function | G 1/4 |
| MSB6-1/2-FRC5:J1M1 | Filter regulator + shut-off valve, G 1/2 bore | G 1/2 |
| MSB6-1/2:J1D1A1-WP | Combination with weatherproof housing and electrical shut-off | G 1/2 |
Typical applications
Typical applications: Compressed air supply points in production lines requiring a defined functional package, machines with safety shut-off of the pneumatic circuit via PLC (emergency stop), outdoor installations requiring weatherproof protection (WP variants), and compact service units in confined installation spaces where multiple separate modules do not fit.
