Festo
185748
Service unit LFR-1/4-D-MIDI-KD-A
The Festo 185748 is a Midi size D series industrial component featuring an on-off valve, a safety start-up valve, and a filter regulator with a pressure gauge. It provides a 40 µm grade of filtration, a fully automatic condensate drain with a 43 cm³ max. condensate volume, and a rotary knob with detent actuator lock. Operating within a pressure range of 3 bar to 12 bar (43.5 psi to 174 psi) and a normal nominal flow rate of 1440 l/min, this unit utilizes a metal bowl guard and operates on compressed air per ISO 8573-1:2010 [-:-:-] or inert gases with a vertical ±5° mounting position.

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.
