Maintenance units with lubricator, FRC
Classic
Festo maintenance units with lubricator of the FRC series combine filtration, pressure regulation and compressed air lubrication in a compact three-component block. Available in MIDI and MAXI sizes with port sizes G1/8 to G1, the lubricator variants are identified by a lubricator type code (KA, KB, KC, KE, KF) that describes the lubricator type and its connection to the regulator. Automatic float drain (5M) or manual drain valve (7), optional differential pressure indicator (DI) and integrated pressure gauge (-A) cover all maintenance tasks on the device.
| Item | Size | Port | Lubricator type |
|---|---|---|---|
| FRC-1/4-D-MIDI-KA | MIDI | G1/4 | KA - standard |
| FRC-1/2-D-MIDI-KA to KF | MIDI | G1/2 | KA / KB / KC / KE / KF |
| FRC-1/2-D-MAXI-KA to KF | MAXI | G1/2 | KA / KB / KC / KE / KF |
| FRC-1/2-D-DI-MAXI-KA/KB/KF | MAXI | G1/2 | KA/KB/KF + DI indicator |
Typical applications: combined compressed air preparation and lubrication for pneumatic cylinders and rotary actuators in assembly and handling systems, maintenance station installation at the machine inlet with automatic condensate drain, preparation for pneumatic tools (screwdrivers, grinders) requiring lubrication, system pressure regulation with integrated oil mist dosing, and replacement of ageing three-component maintenance units in existing systems.
