Festo MS6N-LFM Filter Series

The Festo LF-1/4-D-5M-MINI-A-NPT is a new compressed air filter from the MS series, size 6. It uses a fiber filter design to remove fine particles and condensate from compressed air systems. The unit carries part number 173683 and weighs 600 g. It is supplied as a single unit in a box with a red finish.

Installers needing ISO 8573-1:2010 class 6:8:4 air

This filter suits pneumatic systems that must meet the stated air quality class with a filtration grade of 0.01 µm and 99.9999 % efficiency. It operates between 0 bar and 20 bar pressure. Buyers who require an automatic drain mechanism or a higher flow capacity than 900 l/min should look at alternative models.

Sustained flow between 135 l/min and 900 l/min

Under continuous operation the filter maintains its rated efficiency across the standard flow range from 135 l/min up to 900 l/min. Condensate collects in a 38 ml bowl that is emptied by manually rotating the drain. The housing is built for long service intervals with three years parts coverage and one year labour coverage.

Questions about this item

Does my compressed air system need to supply a minimum flow of 135 l/min for this filter to meet its rated air quality class?

Yes, the filter requires at least 135 l/min to achieve the specified air quality class; below that rate the 0.01 µm filtration grade and 99.9999 % efficiency are not guaranteed.

Will the 1/4 NPT ports on this MS6 series filter connect directly to my existing 1/4 NPT fittings without adapters?

The LF-1/4-D-5M-MINI-A-NPT model uses 1/4 NPT threads, so it mates with standard 1/4 NPT fittings already on your lines.

After installation, how can I confirm the filter is delivering the rated 0.01 µm filtration and 99.9999 % efficiency?

Monitor the differential pressure indicator; a steady reading within the green zone while flow stays between 135 and 900 l/min shows the fiber element is performing to spec.
