Purpose and audience

The Festo MS6N-LFM-1/2-ARV micro filter provides 0.01 µm filtration for compressed air systems requiring high purity. It suits pneumatic installations where residual oil content must stay at 0.01 mg/m3 and flow rates reach 900 l/min.

Thermals noise and power

The unit operates without external power across a medium temperature range of 5 °C to 60 °C. A fully automatic condensate drain removes up to 38 ml of liquid without manual intervention, maintaining steady airflow and filter efficiency of 99.9999 %.

Build and connections

Die-cast aluminum housing with a plastic bowl guard meets corrosion resistance class 2 for moderate stress environments. Dual 1/2 NPT ports allow straight-through piping while the vertical mounting tolerance of +/- 5° eases installation in tight cabinets.

Questions about this item

How do I install the MS6N-LFM-1/2-ARV micro filter and what alignment step is often missed?

Connect the 1/2 NPT ports and mount the housing vertically within ±5°; the bowl guard must face downward so the fully automatic condensate drain can expel the 38 ml capacity correctly.

What part of the MS6N-LFM-1/2-ARV will need replacement and how often?

The borosilicate fiber filter element should be replaced when pressure drop rises or after the rated service interval; the NBR seals and polycarbonate bowl are inspected at the same time.

What is the first limit the MS6N-LFM-1/2-ARV hits during continuous high-flow operation?

The 900 l/min maximum standard flow rate for air quality class is reached before the 12 bar pressure ceiling, so sustained demand above 900 l/min degrades the 0.01 µm filtration grade.
