Festo
The Festo 8229778 is an industrial size 4 filter regulator from the MS series featuring a structural design without a pressure gauge and set up for a G1/4 pressure gauge. It operates within a pressure range of 0.8 bar to 14 bar, offers a regulation range of 0.5 bar to 12 bar, and delivers a normal nominal flow rate of 850 l/min using compressed air or inert gases. Equipped with a 5 µm filtration grade, a manual rotating condensate drain with a 19 ml max volume, a 75 % condensate separation degree, and a rotary knob actuator lock with detent, this component achieves constant output pressure with secondary exhausting and return flow characteristics within a vertical ±5° mounting position.
