Festo
The Festo Size 4 industrial component from the MS series is a filter regulator featuring a rotary knob with detent, integrated pressure gauge, and a structural design incorporating a plastic bowl guard. It operates within a 0.2 MPa to 1.2 MPa pressure range, providing a 0.5 bar to 12 bar regulation range, a 5 µm filtration grade, and a normal nominal flow rate of 1200 l/min for compressed air or inert gases. Configured with both fully automatic and manual non-detenting condensate drains, it maintains a maximum condensate volume of 19 ml and a 75% condensate separation degree with a maximum pressure hysteresis of 0.025 MPa.
