Festo
The Festo size 4 industrial component from the MS series is a filter regulator featuring a structural design without a pressure gauge, a 5 µm filtration grade, and a manual rotating condensate drain with a maximum volume of 19 ml. Engineered with a rotary knob actuator lock with detent that can be closed with accessories, this unit operates within a pressure range of 0.8 bar to 14 bar and delivers a normal nominal flow rate of 1200 l/min using compressed air according to ISO 8573-1:2010 [-:4:-] or inert gases. It provides constant output pressure with secondary exhausting and return flow characteristics, a plastic bowl guard, a 75% condensate separation degree, and a G1/4 setup for a pressure gauge while maintaining a moderate corrosion stress rating of CRC 2.
