Fiber Micro Filter for Compressed Air

The Festo MS6N-LFM-3/8-ARV is a fiber micro filter designed to remove fine particles and oil aerosols from compressed air systems. It achieves a filtration grade of 0.01 µm with 99.9999 % efficiency, delivering a residual oil content of 0.01 mg/m3. The unit features a fully automatic condensate drain and a 38 ml bowl capacity housed in die-cast aluminum with a plastic bowl guard.

Suited for High-Purity Pneumatic Lines

This filter suits installations requiring instrument-grade air quality where sub-micron contamination must be eliminated. It operates between 2 bar and 12 bar with a maximum standard flow rate of 900 l/min and a minimum of 135 l/min. It is not for systems needing only coarse particle separation, applications exceeding the 60 °C medium temperature limit, or pipework incompatible with 3/8 NPT thread connections.

0.01 µm Filtration Grade Decides Fit

The 0.01 µm filtration grade is the single specification determining whether this micro filter meets the required air purity class. It defines the particle and aerosol removal capability critical for sensitive pneumatic components. Verify that the target air quality specification matches this grade before selecting the MS6N-LFM-3/8-ARV.

Questions about this item

How much power does the MS6N-LFM-3/8-ARV micro filter consume during continuous operation?

The MS6N-LFM-3/8-ARV micro filter has no electrical components and consumes zero power. It operates purely on compressed air at 2 to 12 bar with a maximum flow of 900 l/min.

What piping or fittings are required to install the 3/8 NPT connections on this filter?

The filter has 3/8 NPT female threads on both ports. You need male 3/8 NPT fittings and suitable tubing or pipe for your compressed-air line.

Will the 0.01 µm filtration grade protect downstream pneumatic tools that previously used a standard 5 µm filter?

Yes. The 0.01 µm borosilicate fiber element removes 99.9999 % of particles and reduces residual oil to 0.01 mg/m³, far cleaner than a typical 5 µm filter.
