Festo
186493
Filter regulator LFR-1/2-D-O-MAXI-A
The Festo 186493 is a Maxi-size D-series industrial filter regulator featuring a structural design without a pressure gauge, set up for G1/4 pressure gauge connection, and equipped with a rotary knob with detent actuator lock. It operates within a 2 bar to 12 bar operating pressure range, provides a 0.5 bar to 12 bar pressure regulation range with a 0.4 bar max. pressure hysteresis, and delivers a normal nominal flow rate of 9400 l/min for compressed air as per ISO 8573-1:2010 [7:9:-] or inert gases. Built with a metal bowl guard, fully automatic condensate drain, 40 µm filtration grade, and 80 cm³ max. condensate volume, this unit requires a vertical ±5° mounting position and operates with oil lubrication.

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.
