Ultrafine filter LFMA
Classic
The Festo LFMA ultra-fine filter separates oil aerosol particles and fine dust from compressed air and is designed as a downstream stage following the LF standard filter or LFMB fine filter. The 52 versions cover port sizes from G 1/8 to G 1. Variants with the suffix -DA combine a differential pressure indicator and automatic condensate drain in a single housing.
Ultra-fine filtration for oil aerosols - separation of residual oil and fine particles after the LF standard filter stage
Port sizes G 1/8 to G 1 - MINI, MIDI, MAXI; same frame size as LF and LFMB for in-line mounting
Variant -DA - differential pressure indicator signals filter change requirement, automatic condensate drain included
Variant -A - automatic condensate drain without differential pressure indicator, reduced maintenance
Classic compatibility - filter cartridge change (LFMAP) without dismantling the pipework
| Suffix | Condensate drain | Diff. pressure indicator | Typical use |
|---|---|---|---|
| (none) | Manual | No | Basic version, low condensate |
| -A | Automatic | No | Continuous operation, low maintenance |
| -DA | Automatic | Yes | Documented filter change, high requirements |
| -DA-A | Automatic | Yes | Full specification, food/pharma |
Typical applications: Compressed air preparation for painting and coating lines (low residual oil), supply to laboratory measuring instruments and pneumatic precision instruments, use in food and pharmaceutical industries as a third filter stage, and as a quality assurance stage upstream of oil-sensitive instruments and analysers.
