Food-industry fine filter

The Festo MS6N-LFM-1/2-BRV is a 1 µm fiber filter built for compressed-air preparation in food-industry environments. It delivers a maximum standard flow of 950 l/min and a minimum of 140 l/min while meeting ISO 8573-1:2010 class [5:7:3] at the output. Filter efficiency is rated at 99.99 % with a residual oil content of 0.5 mg/m³. The unit is new and supplied as a single pack.

Die-cast aluminium housing with NPT ports

The housing uses die-cast aluminium with a polycarbonate bowl protected by a plastic bowl guard. Seals are NBR and the filter medium is borosilicate fiber. Both pneumatic connections are 1/2 NPT, and the mounting position must stay within vertical ±5°. A fully automatic condensate drain handles up to 38 ml of collected liquid. The assembly weighs 600 g and carries a moderate corrosion-resistance rating of CRC 2.

Operating range and maintenance

Operating pressure spans 2 bar to 12 bar with medium and ambient temperatures from 5 °C to 60 °C. Storage temperature extends down to -10 °C. The automatic drain reduces daily attention, while the bowl guard and CRC 2 rating support durability in moderately corrosive settings. Replacement intervals follow the manufacturer’s parts and labor coverage of 3 years and 1 year respectively.

Questions about this item

What ISO 8573-1:2010 air quality class does the 1 µm filter deliver at its rated flow?

The filter provides compressed air to class [5:7:3] at up to 950 l/min, with 99.99 % efficiency and a residual oil content of 0.5 mg/m³.

What thread size and bowl clearance does the Size 6 housing require?

It uses 1/2 NPT inlet and outlet ports, a die-cast aluminum body with plastic bowl guard, and must be mounted vertically within ±5°.

How is the fully automatic condensate drain commissioned correctly?

Pressurise the system between 2 and 12 bar, verify vertical mounting within ±5°, then confirm the drain cycles — the common error is installing the bowl off-vertical so the float cannot operate.
