Filter Regulator for Pneumatic Systems

The Festo LFR-3/8-D-MIDI-A is a filter regulator designed to clean compressed air and maintain consistent downstream pressure. It combines a 40 µm filter element with a pressure regulation function in a single compact housing. The unit is supplied new in a box as a single pack under part number 159583.

Suited for General Air Preparation Tasks

This device suits workshops and production lines that need reliable air quality and stable pressure for pneumatic tools or actuators. The 40 µm filtration grade handles standard industrial contamination but is not intended for applications requiring fine oil removal or sub-micron particle capture. Buyers needing coalescing filtration or precision pressure control should look at alternative equipment.

40 µm Filtration Grade Defines Air Quality

The filter element rated at 40 µm is the specification that determines whether this regulator meets your air preparation requirements. It protects downstream components from coarse particles and bulk water while allowing a practical flow rate for general-purpose pneumatic circuits. Verify that this filtration level matches the air quality class your equipment demands.

The box contains one filter regulator unit (part number 159583); mounting brackets, tubing fittings and pressure gauges are not included and must be bought separately.

Which version of the Festo MIDI-A filter regulator should I choose for 40 µm filtration?
