Festo
The Festo size 4 industrial component from the MS series is a filter regulator featuring a rotary knob with detent, a 40 µm filtration grade, and a manual rotating condensate drain with a 19 ml maximum volume. Designed with a plastic bowl guard and a structural design excluding a pressure gauge, it delivers a normal nominal flow rate of 1500 l/min across an operating pressure range of 0.08 MPa to 1.4 MPa. The unit provides constant output pressure with secondary exhausting and return flow characteristics within a pressure regulation range of 0.5 bar to 12 bar and a maximum pressure hysteresis of 0.025 MPa.
