Application and purpose

The Festo MS6N-LFX-1/4-R is an active carbon filter built for compressed-air systems in the food industry. It removes oil vapour and odours to deliver air quality class ISO 8573-1:2010 [1:4:1] with a residual oil content of 0.003 mg/m3. The unit operates at pressures from 0 to 20 bar and handles a maximum standard flow rate of 900 l/min.

Included components and effect

The filter ships in a single box as one pack with a plastic bowl guard and a vertical mounting tolerance of +/- 5°. The active carbon element adsorbs hydrocarbons and odour compounds that standard particulate filters miss, extending the service life of downstream equipment. A three-year parts and one-year labour coverage period applies to the assembly.

Installation checks

Verify that your supply pressure does not exceed 20 bar and that the medium temperature stays between 5 °C and 30 °C. Ambient and storage temperatures must remain within -10 °C to 60 °C. The 600 g weight and size 6 housing require a suitable mounting point with vertical alignment. Buyers needing higher flow rates or different port sizes should look at other models.

Questions about this item

How often will the active carbon filter cartridge need replacement?

The filter reduces residual oil content to 0.003 mg/m3 and delivers ISO 8573-1:2010 class [1:4:1] air; cartridge life depends on inlet contamination and running hours, so monitor pressure drop and oil indicators to schedule changes.

What flow limit appears first during continuous high-demand operation?

Maximum standard flow rate is 900 l/min for the rated air quality class; exceeding this reduces filtration efficiency and increases pressure drop across the size-6 housing.

How much heat does the unit add to the compressed-air line when running all day?

The filter has no moving parts or power supply, so it adds negligible heat; medium temperature must stay within 5 °C to 30 °C and ambient within -10 °C to 60 °C for rated performance.
