Micro Filter for Compressed Air Systems

The Festo MS4N-LFM-1/8-AUV-DA is a micro filter designed to remove fine particulates and oil aerosols from compressed air lines. It achieves a filtration grade of 0.01 µm with an efficiency of 99.9999 %, delivering a residual oil content of 0.01 mg/m³. The unit suits pneumatic applications requiring high air purity for sensitive downstream equipment.

Sustained Flow and Condensate Management

The filter operates reliably across a pressure range of 2 bar to 12 bar and handles temperatures from 5 °C to 60 °C. It maintains air quality at standard flow rates between 54 l/min and 360 l/min. A fully automatic condensate drain clears up to 25 ml of collected liquid without manual intervention, while a visual differential pressure display indicates element condition during continuous operation.

Installation Checks Before Ordering

Verify that your supply piping uses 1/8 NPT threads to match the filter's pneumatic connections. Ensure the mounting orientation can stay vertical within a tolerance of +/- 5°. Confirm the ambient environment falls within the 5 °C to 60 °C range and that moderate corrosion resistance (CRC 2) meets your site requirements. The die-cast aluminum housing with integrated metal bowl guard adds 350 g to the assembly.

Questions about this item

How much pressure drop and heat should I expect when the MS4N-LFM-1/8-AUV-DA runs continuously at its 360 l/min rating?

The filter operates between 2 and 12 bar with a visual differential-pressure display; medium and ambient temperatures are rated 5 °C to 60 °C, so sustained flow at 360 l/min stays within those thermal limits.

Which fittings and drain arrangement must I already have to install this 1/8 NPT micro filter?

Both ports are 1/8 NPT and the bowl includes a fully automatic condensate drain with a 25 ml capacity, so you need matching 1/8 NPT piping and a discharge route for the drained liquid.

Will the MS4N-LFM-1/8-AUV-DA work inline with older Festo MS series components that use different bowl guards?

The housing is die-cast aluminum with an integrated metal bowl guard and the mounting position is vertical ±5°, matching the standard MS series envelope for direct series connection.
