Festo
539684
Filter regulator LFR-1/8-DB-7-MINI-H
The Festo part number 539684 is a mini series DB filter regulator with a pressure gauge and a 44 mm width, designed with a vertical assembly position of +/- 5° and a semi-automatic condensate drain. It features a rotary knob with a lock actuator lock, a 40 µm grade of filtration, a controller function with secondary exhaust and return flow, a working pressure of 1.5 to 10 bar, a pressure 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. Operating on compressed air to ISO 8573-1:2010 [-:9:-] or inert gases with a medium and ambient temperature range of -5 to 50 °C, this 200 g component achieves a corrosion resistance classification CRC of 1 and an output air purity class of ISO 8573-1:2010 [7:8:4].
