Festo LF-D-MAXI-A-U Filter Regulator

The Festo LF-D-MAXI-A-U is a Size Maxi filter regulator designed for compressed-air systems that require automatic condensate removal. It combines a sinter filter with a centrifugal separator to deliver a 40 µm filtration grade in a single unit. The metal bowl guard protects the 79.968 ml condensate reservoir in demanding environments. This new component suits maintenance teams and machine builders who need reliable air preparation.

Check operating pressure

Verify that your supply pressure falls between 1.931 bar and 12.411 bar and that the medium temperature stays within 5 °C to 60 °C. The housing must be mounted vertically within a tolerance of ±5° for the automatic drain to function correctly. Ensure the port size matches your existing piping and that the ambient conditions remain inside the stated 5 °C to 60 °C window. Maritime installations should confirm the applicable classification certificate.

Sustained-load behaviour with automatic drainage

At the standard nominal flow rate of 22245.76 l/min the regulator maintains consistent pressure while the centrifugal separator continuously ejects liquid condensate. The fully automatic drain prevents bowl flooding during extended shifts without manual intervention. Corrosion resistance class 2 tolerates moderate corrosion stress over long production runs. The 1329.615 g weight reflects the robust metal construction that resists vibration in continuous operation.

Questions about this item

Does the box include the filter regulator only or are mounting brackets and tubing supplied separately?

The box contains one LF-D-MAXI-A-U filter regulator with metal bowl guard and fully automatic condensate drain; mounting hardware and pneumatic tubing are not included.

The catalogue lists a single Maxi size — are there alternative bowl capacities or filtration grades for this series?

This Maxi variant comes with a 40 µm sinter filter and a 79.968 ml condensate volume; other bowl sizes or micron ratings belong to different LF series codes.

What does the 22245.76 l/min standard nominal flow rate mean when the unit is installed in a 12.411 bar system?

At the maximum 12.411 bar operating pressure the regulator can pass up to 22245.76 l/min of filtered air, provided upstream piping and downstream demand match that capacity.
