Service units without lubricator, LFR
Classic
The Festo LFR-series maintenance units without lubricator combine filter-control valve and on-off valve in pre-assembled units. The suffix structure KA to KG defines the unit composition: which components (HE, HEL, HEE) are combined with the LFR. With 135 versions, this range offers ready-configured maintenance units without a separate lubricator for oil-free compressed air applications.
| Suffix | Component combination | Main application |
|---|---|---|
| -KA | HE + LFR | Manual switch-on + filter regulation |
| -KA-A | HE + LFR, auto drain | As KA, reduced maintenance |
| -KB | HE + HEL + LFR | Switch-on + soft-start + filter regulation |
| -KC/-KD/-KE | Variations with HEE (electric) | Electrically controlled switch-on |
| -KF/-KG | Extended variants | Special combinations |
Typical applications: Maintenance units for oil-free compressed air in food and pharmaceutical industries, decentralised compressed air preparation at assembly machines without oil mist, compact units for confined spaces where individual components do not fit, and replacement of existing individual component solutions with pre-configured units during plant overhauls.
