Activated carbon filter LFX
Classic
The Festo LFX activated carbon filter removes residual oil vapours and organic contaminants from compressed air that mechanical particle filters cannot separate. The range covers 13 versions from G 1/8 to G 1 (MINI, MIDI, MAXI) and is installed as the final filtration stage downstream of an LFMA ultra-fine filter to reach compressed air class 1 per ISO 8573-1.
Activated carbon adsorption - binds residual oil vapours and gaseous hydrocarbons that pass through particle filters
Port sizes G 1/8 to G 1 - MINI, MIDI, MAXI; fits as final stage in all Classic filter trains
Target: ISO 8573-1 Class 1 - compressed air for direct food contact and breathing air applications
Replacement cartridge LFACP - separate LFACP-MIDI and LFACP-MAXI cartridges for maintenance without housing replacement
Dry installation required - must be installed downstream of LFMA; condensate-free air is a prerequisite for activated carbon performance

Typical applications: Final purification stage in compressed air filter systems for direct food contact (ISO 8573-1 Class 1 oil), breathing air supply and diving air (compressed-air-dependent breathing protection devices), paint booths requiring odour-free compressed air, and pharmaceutical production with clean air requirements per EU GMP guidelines.
