Festo
185733
Service unit LFR-1/4-D-MINI-KC
The Festo part number 185733 is a mini D-series structural assembly combining an on/off valve and a filter regulator with a pressure gauge, featuring a vertical ±5° mounting position and a rotary knob with detent for the actuator lock. It operates within a pressure range of 1 bar to 16 bar and regulates pressure from 0.5 bar to 12 bar, delivering a normal nominal flow rate of 1150 l/min for compressed air as per ISO 8573-1:2010 [-:-:-] or inert gases. Equipped with a 40 µm filtration grade, a manual rotating condensate drain with a 22 cm³ maximum condensate volume, and a metal bowl guard, the unit achieves a maximum pressure hysteresis of 0.2 bar and provides an output air quality class of ISO 8573-1:2010 [7:8:4] under a 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.
