Fine filter LFMB
Classic
The Festo LFMB fine filter is the intermediate filtration stage between the LF standard filter and the LFMA ultra-fine filter. It separates finer particles and residual oil than the LF and is used where fine dust would impair the function of sensitive pneumatic components. The 52 versions cover port sizes from G 1/8 to G 1, including -DA variants with differential pressure indicator and automatic condensate drain.
| Suffix | Condensate drain | Diff. pressure indicator | Main use |
|---|---|---|---|
| (none) | Manual | No | Basic version, low condensate volumes |
| -A | Automatic | No | Continuous operation, low maintenance |
| -DA | Automatic | Yes | Maintenance diagnostics, process air cleaning |
| -DA-A | Automatic | Yes | Maximum specification, sensitive applications |
Typical applications: Two-stage compressed air preparation (LF + LFMB) for assembly automats and robots, protection of proportional valves and servo-pneumatic components against fine particles, use in electronics manufacturing and semiconductor assembly, and as fine filtration upstream of activated carbon filters (LFX) in odour-sensitive processes.
