Pressure Regulator for Pneumatic Systems

The Festo LR-3/4-D-MIDI is a pressure regulator designed to control compressed air in pneumatic installations. It maintains a consistent output pressure regardless of fluctuations in the input supply. The unit is supplied new in a single box under part number 162581. Its red finish provides clear visual identification in industrial environments.

Suited for Air Preparation Tasks

This regulator suits technicians and engineers setting up or maintaining pneumatic circuits that require stable pressure control. It is not intended for hydraulic fluid or gas regulation applications. Buyers needing integrated filtration or lubrication functions should look at combination service units instead. The component serves specifically as a standalone pressure control device.

G3/4 Port Connection Size

The defining specification is the G3/4 port thread size, which determines compatibility with existing piping and fittings. Matching this connection standard is essential for correct installation and sealing. Verify that your system uses this thread size before purchasing. The three-year parts and one-year labor coverage applies to the regulator unit.

Questions about this item

What compressed-air supply and fittings must I already have to install the LR-3/4-D-MIDI regulator?

You need a compressed-air source with a G 3/4 port and supply pressure up to 16 bar, plus thread-seal tape or compound for the connection.

Will the LR-3/4-D-MIDI work with my existing Festo MIDI-series filters and lubricators?

Yes, the regulator shares the MIDI modular design so it bolts directly to other MIDI components using the standard connecting plates.

How can I confirm the LR-3/4-D-MIDI is regulating pressure correctly after installation?

Turn on the air supply, adjust the knob until the built-in gauge shows your desired outlet pressure, then verify the reading stays steady while downstream equipment runs.
