Festo
185773
Service unit LFR-3/8-D-MIDI-KF
The Festo part number 185773 is a Midi-size Series D industrial component featuring a structural design that combines a branching module, pressure switch, on/off valve, and a filter regulator with a pressure gauge. It operates within a pressure range of 1 bar to 16 bar (0.1 MPa to 1.6 MPa, 14.5 psi to 232 psi) and provides a normal nominal flow rate of 2420 l/min using compressed air or inert gases as the operating medium. Equipped with a 40 µm filtration grade, a manual rotating condensate drain with a 43 cm³ max volume, and a metal bowl guard, this unit maintains a pressure regulation range of 0.5 bar to 12 bar.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
