Festo
531227
Filter regulator MS4N-LFR-1/4-D6-ERV-AS-Z
The Festo 531227 is a size 4 MS-series filter regulator featuring a design structure with a pressure gauge, a 40 µm filtration grade, and a fully automatic condensate drain with a maximum condensate volume of 19 ml. Engineered for compressed air operating within an inlet pressure range of 2 to 12 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. It includes a plastic bowl guard, a lockable actuator lock via accessories, and operates at medium temperatures between 5 and 60 µC within a vertical assembly position of +/- 5°.
