Festo
526291
Filter regulator LFR-QS4-D-7-O-5M-MICRO
The Festo 526291 is a micro-sized D-series industrial filter regulator designed without a pressure gauge and equipped with an M5 ready connection for pressure gauging. This component features a rotary knob with lock actuator, a manual rotary condensate drain with a 3 cm3 maximum condensate volume, and a 5 µm filtration grade operating at a working pressure of 1 to 10 bar and a pressure regulation range of 0.5 to 7 bar. It delivers a standard nominal flow rate of 170 l/min for compressed air to ISO 8573-1:2010 [7:9:-] and inert gases, functioning within a medium and ambient temperature range of -10 to 60 µC.
