Festo LFR-D-MIDI-A | LFR Series Filter Regulator MIDI Size, G1/4 or G3/8 Port, 40 µm, Metal Bowl, Auto Drain
Festo LFR-D-MIDI-A modular filter regulator (LFR series, MIDI size) — 5 µm / 40 µm filtration, relief-type regulator 0.05–0.85 MPa, metal bowl with sight glass, auto drain. G1/4 or G3/8 port, for MS/ES series modular FRL banks.

Product Overview

The Festo LFR-D-MIDI-A​ is a modular combination filter regulator (FRL)​ from Festo's LFR series in MIDI body size (≈ G1/4–G3/8 port range). It integrates a particulate filter (standard 40 µm — 5 µm optional)​ and a relief-type pressure regulator (0.05–0.85 MPa / 7–123 psi)​ in one unit. The "-D" denotes a metal bowl with polycarbonate sight glass and semi-automatic (float-type) drain; "-A" specifies the MIDI size with standard mounting holes / alignment pins​ for coupling with Festo MS/ES series lubricators, soft-start valves, or shut-off valves using union connectors. Ports are typically G1/4​ (for LFR-1/4-D-MIDI-A) or G3/8​ (LFR-3/8-D-MIDI-A) — the generic "LFR-D-MIDI-A" code is a family descriptor; exact port thread is selected by the numeric prefix in the full order code (e.g. LFR-1/4-D-MIDI-A = 159630​ / LFR-3/8-D-MIDI-A = 159631). Suitable for main air line conditioning upstream of valves and actuators.

Key Features

  • Space-Saving Combo:​ One unit replaces separate filter + regulator — reduces piping, weight, and envelope on the air header.
  • Semi-Auto Float Drain (D):​ Condensate evacuates automatically when unit depressurizes or via manual push-button — no constant air loss unlike timed auto drains.
  • Metal Bowl + Sight Glass:​ Robust metal bowl with visible fluid level; optional full polycarb bowl (no guard) or metal bowl with guard available in other suffixes.
  • Modular Expandability:​ Couples directly with Festo MS6-LR (regulator-only), MS6-F (filter-only), MS6-LFM (lubricator), MS6-D (shut-off), MS6-SV (soft-start) using union nuts.
  • Lockable Regulator Knob (on most -A variants):​ Push-to-lock or pull-to-adjust — prevents unauthorized pressure changes on the shop floor.

Typical Applications

  • Main Air Line Conditioning:​ Installed at machine entry to clean and regulate shop air before distribution to valves/cylinders.
  • Packaging / Assembly Machinery:​ Consistent regulated pressure + particle-free air critical to cycle repeatability.
  • Panel Build / OEM Skids:​ Compact FRL bank with modular add-ons (lubricator, gauge, shut-off) — easy to specify and assemble.
  • Retrofit / Upgrade:​ Drop-in replacement for older Festo or other ISO-compliant FRL brands with same port spacing in MIDI envelope.
