Micro filter for compressed air systems

This Festo MS6N-LFM-1/2-ARV-DA-Z micro filter removes fine particles and oil aerosols from compressed air lines. It achieves a filtration grade of 0.01 µm with 99.9999 % efficiency, delivering air quality class ISO 8573-1:2010 [1:7:2]. The unit operates between 2 bar and 12 bar with a maximum standard flow rate of 900 l/min. A fully automatic condensate drain and visual differential pressure display simplify maintenance.

Installers needing ISO 8573-1 Class 1 particle

Pneumatic technicians and machine builders who require residual oil content down to 0.01 mg/m³ will benefit from this fiber filter. It suits systems with 1/2 NPT ports and flow rates between 135 l/min and 900 l/min. Buyers who need a coarser pre-filter or an activated carbon stage for vapour removal should look at a different filter type. Installations requiring port sizes other than 1/2 NPT cannot use this housing directly.

Filtration grade 0.01 µm decides suitability

The 0.01 µm borosilicate fiber element determines whether this filter meets the application's air purity target. It captures sub-micron particles and oil mist to reach Class 1 particle and Class 2 oil ratings. If the process demands a different micron rating or a chemical adsorption stage, this specific element will not satisfy the requirement.

Questions about this item

What thread size do I need on my airline to connect this micro filter?

Both ports are 1/2 NPT, so the filter fits directly onto a 1/2 NPT compressed-air line without adapters.

How do I install the filter so the automatic drain works, and what step is often missed?

Mount the housing vertically with the bowl pointing down, connect flow in the direction of the arrow, and pressurise slowly — the step often missed is leaving the bowl loose enough for the float mechanism to move freely.

When should I replace the borosilicate fiber element inside this Size 6 filter?

Replace the element when the visual differential-pressure indicator shows a high pressure drop or after the filter has processed its rated service life; the bowl holds up to 38 ml of condensate before the automatic drain actuates.
