Festo
8098257
Filter regulator MS4-LFR-1/4-D6-C-P-M-AG-BAR-B
The Festo part number 8098257 is an MS-series size 4 industrial component featuring a structural design that combines a filter regulator with a pressure gauge and a directly controlled piston regulator. It provides a 5 µm filtration grade, a 75% degree of condensate separation, a 16.5 ml maximum condensate volume, and a normal nominal flow rate of 1500 l/min for compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases. Operating within a pressure range of 1 bar to 10 bar, it offers a pressure regulation range of 0.3 bar to 7 bar governed by a rotary knob with detent actuator lock and secondary exhausting.
