1 µm Fine Filter for Compressed Air

The Festo MS6N-LFM-1/4-BRM-DA is a fiber filter designed to remove fine particles and oil aerosols from compressed air systems. It achieves a filtration grade of 1 µm with 99.99 % efficiency, delivering a maximum standard flow rate of 950 l/min. The unit features a die-cast aluminum housing with a plastic bowl guard and NBR seals, suitable for operating pressures up to 20 bar.

Suited for food-industry prep, not general dust

This filter suits installations requiring high-purity compressed air, such as food-industry applications where residual oil content must stay at 0.5 mg/m³. It is not intended for coarse particulate separation or bulk liquid removal where a pre-filter would be more appropriate. Buyers needing automatic condensate discharge should look elsewhere, as this model uses a manually rotating drain.

1/4 NPT ports fix the connection size

The filter provides two 1/4 NPT pneumatic connections, which determine whether it fits existing piping without adapters. The housing must be mounted vertically within a 5° tolerance for correct operation. Operating and ambient temperatures range from -10 °C to 60 °C, and the bowl holds up to 38 ml of condensate before manual draining is required.

Questions about this item

What NPT thread size do the pneumatic ports use on the MS6N-LFM-1/4-BRM-DA?

Both pneumatic connections are 1/4 NPT, so you need matching 1/4 NPT fittings and sealant rated for up to 20 bar operating pressure.

Which way up must the filter bowl sit during installation?

The unit must be mounted vertically within ±5°; tilting beyond that prevents the manual rotating drain from evacuating the 38 ml condensate capacity.

How often should the borosilicate fiber element be changed?

Replace the element when the visual differential-pressure indicator shows a pressure drop approaching the filter's 99.99 % efficiency limit, typically after the rated service interval for your air quality class.
