Festo LFR-D-MIDI Filter Regulator

The Festo LFR-D-MIDI Filter Regulator 546425 Series D is a pneumatic test equipment unit designed for air preparation tasks. It combines filtration and pressure regulation in a single compact housing finished in red. The product is supplied as one pack in a box and carries a three-year parts warranty with one-year labor coverage.

Suited for pneumatic system maintenance

This filter regulator suits technicians who need reliable air filtration and precise pressure control for pneumatic circuits. It is not intended for applications that require integrated lubrication, digital pressure monitoring, or multi-stage filtration beyond the standard MIDI series capability.

Consistent pressure delivery over time

Under sustained operation the unit maintains steady outlet pressure while continuously removing particulates and condensate from the compressed air stream. The filter element and regulator diaphragm are built for extended duty cycles without performance drift during prolonged use.

Questions about this item

What compressed-air supply and fittings do I need to connect the LFR-D-MIDI filter regulator?

The unit requires a clean, dry compressed-air line with standard G-thread ports; supply pressure must stay within the regulator's rated range and a suitable mounting bracket or panel cut-out is needed for secure installation.

Will the Series D 546425 regulator work with my existing Festo MIDI-series valves and tubing?

Yes, Series D shares the same port thread and flow characteristics as earlier MIDI generations, so it connects directly to existing valves, tubing and manifold blocks without adapters.

How can I verify the 546425 filter regulator is delivering the correct outlet pressure after installation?

Turn on the air supply, adjust the knob until the built-in gauge reads the desired set pressure, then cycle a downstream actuator to confirm the gauge holds steady under load.
