Compressed Air Filter 5 µm

The Festo LF-3/8-D-5M-MINI-A-NPT is a mini-series compressed air filter designed for pneumatic systems requiring fine particle removal. It suits maintenance engineers and automation technicians who need reliable air preparation at the point of use. The unit filters down to 5 µm and includes a fully automatic condensate drain.

Operating Pressure Range 2 to 12 bar

This filter operates within a pressure range of 2 bar to 12 bar, defining the practical window for installation. Systems running below 2 bar will not actuate the drain reliably, while pressures above 12 bar exceed the housing rating. The 3/8 NPT ports on both inlet and outlet fix the connection standard.

Flow Capacity 1100 l/min

At standard conditions the filter delivers a nominal flow rate of 1100 l/min, providing headroom for typical actuator circuits and air tools. The metal bowl guard protects the polycarbonate bowl in harsh environments, while the 22 ml condensate capacity determines drain frequency under high humidity. The PE filter element handles continuous duty within these limits.

Questions about this item

What does the 5 µm filtration grade mean for my compressed air system?

The 5 µm grade removes particles down to five microns, protecting downstream pneumatic tools and valves from fine contamination.

What does the 1100 l/min standard nominal flow rate mean once the filter is installed?

It indicates the maximum airflow the filter can pass at 6 bar supply pressure and 1 bar pressure drop, so size your compressor and piping accordingly.

How do the 3/8 NPT connections affect what fittings I can use?

Both ports use 3/8 inch NPT threads, so you need matching NPT fittings or adapters; the threads are not compatible with BSP or metric ports.
