Festo
8098259
Filter regulator MS4-LFR-1/4-D6-C-P-VC-AG-BAR-B
The Festo part number 8098259 is an industrial filter regulator of size 4 from the MS series, featuring a directly controlled piston design with a rotary knob actuator lock and integrated pressure gauge displaying in bar and psi. This component operates within a pressure range of 0.2 MPa to 1 MPa (2 bar to 10 bar) and a regulation range of 0.3 bar to 7 bar, delivering a normal nominal flow rate of 1500 l/min for compressed air conforming to ISO 8573-1:2010 [7:4:4] or inert gases. It incorporates a 5 µm filtration grade, a 75% condensate separation degree, a maximum condensate volume of 16.5 ml, and both fully automatic and manual non-detenting condensate drains while maintaining a vertical ±5° mounting position.
