Festo
529223
Filter regulator MS6-LFR-3/8-D6-ERV-AS-Z
The Festo 529223 is an MS-series size 6 filter regulator featuring a 40 µm grade of filtration, a fully automatic condensate drain with a 38 ml maximum condensate volume, and an integrated pressure gauge. Operating within a working pressure range of 2 to 12 bar and a pressure control range of 0.3 to 7 bar, this unit delivers a standard nominal flow rate of 5,700 l/min while maintaining a constant output pressure with secondary exhaust. Designed with a plastic bowl guard, a rotary knob actuator lock with accessory lockability, and a vertical +/- 5° assembly position, it processes compressed air per ISO8573-1:2010 [7:4:-] or inert gases within a medium temperature range of 5 to 60 °C.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
