Festo
537651
Filter regulator LFR-1/8-DB-7-O-MINI
The Festo 537651 is a mini DB-series filter regulator featuring a 44 mm width, a 40 µm filtration grade, and a manual rotary condensate drain. This component operates within a working pressure range of 1.5 to 10 bar, a pressure regulation range of 0.5 to 7 bar, and delivers a standard nominal flow rate of 700 l/min or greater for compressed air to ISO 8573-1:2010 [-:9:-] or inert gases. Equipped with a lockable rotary knob actuator, secondary exhaust, return flow, and a G1/8-prepared pressure gauge port, the 200 g unit functions within a medium and ambient temperature range of -5 to 50 µC.
