Festo
529165
Filter regulator MS4-LFR-1/8-D6-ERM-AS-Z
The Festo part number 529165 is a size 4 MS-series filter regulator featuring a 40 µm filtration grade, a manual rotary condensate drain, and a 19 ml maximum condensate volume within a plastic bowl guard. Designed with a built-in pressure gauge and a rotary knob lock actuator, this unit operates within a working pressure of 0.8 to 14 bar and a pressure control range of 0.3 to 7 bar to deliver a standard nominal flow rate of 1,000 l/min. It maintains a constant output pressure for compressed air to ISO 8573-1:2010 [-:4:-] and inert gases, functioning in medium and storage temperatures from -10 to 60 µC in a vertical +/- 5° assembly position.
