Festo
The Festo size 4 industrial component from the MS series is a fiber filter featuring a fully automatic condensate drain and an integrated metal bowl guard, designed for vertical installation within a plus-or-minus 5-degree tolerance. Operating at a working pressure of 2 to 12 bar, this unit achieves a 99.99% filter efficiency at 1 µm with a maximum condensate volume of 25 ml and a standard flow rate ranging from 54 to 360 l/min using compressed air or inert gases. Weighing 350 g, the device processes media within a temperature range of 5 to 60 °C to deliver an output air purity class of ISO8573-1:2010 [2:7:3] with a residual oil content of 0.5 mg/m3.
