Festo
537649
Filter regulator LFR-1/8-DB-7-O-MINI-H
The Festo 537649 is a mini DB-series filter regulator featuring a 44 mm width, a 40 µm filtration grade, and a semi-automatic condensate drain designed for vertical installation within a +/- 5° tolerance. It operates with a working pressure of 1.5 to 10 bar, a regulation range of 0.5 to 7 bar, a maximum pressure hysteresis of 0.5 bar, and a standard nominal flow rate of 700 l/min or greater while utilizing compressed air or inert gases across a temperature range of -5 to 50 ¼irc}C. This 200 g unit includes a rotary knob with lock, secondary exhaust, return flow, and G1/8 pressure gauge preparation, achieving corrosion resistance class CRC 1 and an output air purity class of ISO 8573-1:2010 [7:8:4].
