Compressed Air Filter for Pneumatic Systems
The Festo LF-1-D-5M-MAXI-NPT is a Maxi-series compressed air filter designed to remove particulates down to 5 µm from pneumatic lines. It handles a standard nominal flow rate of 3800 l/min with a 1 NPT port on each side. The die-cast zinc housing and polycarbonate bowl with metal guard suit industrial environments. A manual, non-detenting drain releases up to 80 ml of condensate.
Suitable Applications and Limitations
This unit suits plant engineers and maintenance teams needing reliable filtration at operating pressures up to 16 bar in a vertical mounting orientation. It is not for buyers who require automatic condensate drainage or a filter grade finer than 5 µm. The RoHS-compliant construction meets moderate corrosion stress demands. Teams needing higher flow capacity or a different port standard should look elsewhere.
Deciding Specification: 5 µm Filtration Grade
The 5 µm grade of filtration is the single figure that determines whether this filter matches your air-quality requirement. If your pneumatic tools or processes demand cleaner air, this grade will not be sufficient. If 5 µm meets the specification, the 3800 l/min flow capacity and 1 NPT connections become the next checks. Verify the vertical mounting requirement against your installation layout.

Questions about this item
How do I install the LF-1-D-5M-MAXI-NPT filter and which step is most often missed?
Mount the housing vertically with the bowl facing down, connect 1 NPT ports to your compressed air line, and fit the metal bowl guard before pressurising — the vertical orientation is the step installers forget.
What maintenance will the 5 µm filter element and 80 ml condensate bowl need over time?
Replace the PE filter cartridge when pressure drop rises, and manually drain the 80 ml bowl before it fills; the bowl guard stays in place during service.
At what flow rate does the 16 bar rated housing hit its 3800 l/min nominal limit during continuous operation?
The standard nominal flow rate is 3800 l/min at 6 bar supply; sustained demand above that level increases pressure drop across the 5 µm element first.
