Festo
185750
Service unit LFR-3/8-D-MIDI-KD-A
The Festo 185750 is a Midi-size industrial component from the D series, featuring a structural design that integrates an on/off valve, a filter regulator with a pressure gauge, and a safety start-up valve. Operating within a pressure range of 3 bar to 12 bar (0.3 MPa to 1.2 MPa) and achieving a normal nominal flow rate of 1890 l/min, this unit incorporates a 40 µm filtration grade, a fully automatic condensate drain with a 43 cm³ max condensate volume, and a metal bowl guard. It is designed for vertical mounting within ±5° and utilizes a rotary knob with detent for actuator locking while maintaining a moderate corrosion resistance class of CRC 2.

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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
