Festo
531309
Filter regulator MS6N-LFR-1/2-D6-CRM-AS-Z
This Festo industrial component, part number 531309, is an MS-series size 6 filter regulator with a pressure gauge, designed for compressed air operation with a standard nominal flow rate of 5,600 l/min and a pressure control range of 0.3 to 7 bar. Featuring a 5 µm filtration grade, a manual rotary condensate drain with a 38 ml maximum condensate volume, and a plastic bowl guard, the unit maintains a constant output pressure with secondary exhaust and includes a lockable actuator lock via accessories. It operates within a medium and storage temperature range of -10 to 60 µC, an inlet pressure of 0.8 to 20 bar, and achieves an air purity class at the output of 3.7.- per DIN ISO 8573-1 alongside a corrosion resistance classification CRC of 2 in a vertical +/- 5° assembly position.
