Festo
The Festo Size 4 MS series filter regulator features a structural design integrating a pressure gauge, rotary knob with detent actuator lock, and plastic bowl guard for vertical installation within a plus-or-minus 5-degree tolerance. It operates within a 2 bar to 12 bar pressure range, delivering a 1500 l/min normal nominal flow rate for compressed air as per ISO 8573-1:2010 [7:4:-] or inert gases, while providing a 40 µm filtration grade and 75 percent condensate separation with fully automatic or manual non-detenting drainage. Featuring constant output pressure, secondary exhausting, and return flow characteristics, this component achieves a maximum pressure hysteresis of 0.25 bar and a maximum condensate volume of 19 ml under moderate corrosion stress of CRC 2.
