Festo
The Festo size 4 industrial component from the MS series is a filter regulator lubricator featuring a structural design with a 40 µm grade of filtration, a 19 ml max. condensate volume, and a 30 cm³ max. oil capacity. It operates within a pressure range of 0.15 MPa to 1.4 MPa (1.5 bar to 14 bar) and provides a pressure regulation range of 1 bar to 7 bar with a maximum standard flow rate of 1400 l/min using compressed air as per ISO 8573-1:2010 [-:4:-] or inert gases. Equipped with a manual rotating condensate drain, a plastic bowl guard, a rotary knob actuator lock with detent that can be closed with accessories, and a pressure gauge, this unit functions with constant output pressure, primary pressure compensation, secondary exhausting, and a return flow characteristic.
