Filter regulator LFR-1/2-D-16-5M-O-MIDI-T18-EX4

The Festo part number 4772770 is a Series D Midi industrial component functioning as a filter regulator without a pressure gauge, featuring a structural design with a 5 µm filtration grade and a manual rotating condensate drain with a maximum volume of 42 cm³ inside an integrated metal bowl guard. Operating within a pressure range of 1 bar to 20 bar and a regulation range of 0.5 bar to 16 bar, this unit achieves a normal nominal flow rate of 1665 l/min while supporting a G1´4 pressure gauge setup and maintaining a vertical mounting position within ±5°. Actuation is controlled via a rotary knob with a detent, and the assembly includes CE and UKCA markings alongside EPL Db and EPL Gb certifications for explosion protection in ATEX and UKEX zones 1, 2, 21, and 22, covering gas category II 2G and dust category II 2D.
