Festo
531223
Filter regulator MS4N-LFR-1/4-D6-ERM-AS-Z
The Festo part number 531223 is an industrial MS series size 4 filter regulator with a pressure gauge and a manual rotary condensate drain featuring a 19 ml max. condensate volume and a 40 µm grade of filtration. Designed for compressed air operation with an inlet pressure range of 0.8 to 14 bar and a pressure control range of 0.3 to 7 bar, this component delivers a standard nominal flow rate of 1,700 l/min while maintaining a constant output pressure with secondary exhaust and return flow. Housed with a plastic bowl guard and a corrosion resistance classification CRC of 2, the unit operates at temperatures between -10 and 60 µ0°C and achieves an air purity class at output of 5:7:- per DIN ISO 8573-1 in a vertical +/- 5° assembly position.
