Filter Regulator Function

The Festo LFR-1/4-D-MIDI-A is a filter regulator designed to clean and control compressed air pressure in pneumatic systems. It combines particle filtration with precise pressure adjustment in a single compact unit. The 43 cm3 internal volume suits small to medium air flow requirements. Model 186484 identifies this specific MIDI series configuration.

Suitable Applications

This unit suits maintenance technicians and automation engineers who need reliable air preparation for actuators, valves or air tools. It fits installations where space is limited and a combined filter-regulator reduces piping complexity. Buyers who require separate high-capacity filtration or oil removal should look at dedicated filter or coalescing units instead.

Key Specification

The 43 cm3 bowl capacity determines how much condensate and particulate the filter can hold before draining is required. This volume directly sets the maintenance interval for a given air quality and flow rate. Verify that the capacity matches your system duty cycle to avoid unexpected pressure drops or contamination carry-over.

Questions about this item

What does the 43 cm³ capacity mean when the regulator is installed in a pneumatic circuit?

It indicates the internal volume of the filter-regulator housing, which determines how much compressed air is held inside the unit during operation.

Which connection standard does the G 1/4 port follow and what flow limit does it impose?

The port uses a G 1/4 thread for standard pneumatic fittings; the regulator’s internal design sets the practical flow ceiling for the system.

What physical space and mounting method does the MIDI body require?

The MIDI-series body fits standard DIN-rail or bracket mounts and needs clearance for the 43 cm³ housing plus the bowl and adjustment knob.
