Festo
531280
Filter regulator MS6N-LFR-3/8-D7-ERV-AS-Z
The Festo 531280 is an MS-series size 6 filter regulator with a pressure gauge, designed for compressed air operation within an inlet pressure range of 2 to 12 bar and a pressure control range of 0.5 to 12 bar. It features a 40 µm grade of filtration, a fully automatic condensate drain with a maximum condensate volume of 38 ml, a plastic bowl guard, and a standard nominal flow rate of 4,000 l/min. The unit provides a constant output pressure with secondary exhaust, a maximum pressure hysteresis of 0.25 bar, and delivers an air purity class at output of 5:7:- per DIN ISO 8573-1 while maintaining a corrosion resistance classification CRC of 2 in a vertical assembly position within +/- 5°.
