Festo
185753
Service unit LFR-3/4-D-MAXI-KD
This Festo D-series industrial component in size Maxi features an integrated on/off valve, a filter regulator with a pressure gauge, and a safety start-up valve configured for vertical installation within ±5°. Operating at an input pressure range of 0.3 MPa to 1.6 MPa (3 bar to 16 bar / 43.5 psi to 232 psi), the unit delivers a normal nominal flow rate of 5000 l/min while providing a 40 µm filtration grade and a manual rotating condensate drain with an 80 cm³ maximum condensate volume. The assembly incorporates a metal bowl guard, a rotary knob with detent for actuator locking, and operates with compressed air or inert gases across a pressure regulation range of 0.25 MPa to 1.2 MPa (2.5 bar to 12 bar / 36.25 psi to 174 psi).

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.
