Festo
185741
Service unit LFR-3/4-D-MAXI-KC
The Festo 185741 industrial component integrates an on/off valve and a filter regulator with a pressure gauge in a Maxi size D-series structural design. Operating with compressed air or inert gases across an operating pressure range of 1 bar to 16 bar, this unit achieves a normal nominal flow rate of 8400 l/min with a 40 µm filtration grade and a maximum condensate volume of 80 cm³. It features a rotary knob actuator lock with detent, a manual rotating condensate drain, a metal bowl guard, and vertical ±5° mounting orientation.

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.
