Festo Midi Compressed Air Filter 5 µm

The Festo LF-3/8-D-5M-MIDI-A-NPT is a midi-sized compressed air filter rated for a standard nominal flow of 1800 l/min. It removes particles down to 5 µm and operates between 2 bar and 12 bar. The housing is die-cast zinc with a polycarbonate bowl protected by a metal bowl guard. Connections are 3/8 NPT on both ports.

Suits pneumatic systems needing fine filtration

This filter suits installations that require 5 µm filtration with a fully automatic condensate drain capable of holding 43 ml. It is not for systems that run below 2 bar or above 12 bar, nor for applications needing a coarser or finer filtration grade than 5 µm. Buyers who need a different port thread or a manual drain should look at other models.

Check your supply pressure port thread

Verify that your compressed air line uses 3/8 NPT fittings to match both pneumatic connections. Confirm the operating pressure stays within the 2 bar to 12 bar range and that the ambient temperature remains between 5 °C and 60 °C. Ensure the polycarbonate bowl material is compatible with the oils and chemicals present in your air supply.

Questions about this item

Does the filter need a 3/8 NPT thread on both the inlet and outlet of my compressed-air line?

Yes, both pneumatic connections are 3/8 NPT, so the line must provide matching threads on the supply and return sides.

Will the automatic drain still empty the bowl if my compressor only reaches 2 bar?

The filter operates from 2 bar up to 12 bar, so the fully automatic drain will function at the minimum pressure of 2 bar.

How can I confirm the filter is removing particles down to 5 µm after installation?

A drop in pressure differential across the filter and no visible contamination downstream indicate the 5 µm element is working as intended.
