SMC Corporation AF40-N03B-Z-A-X2141 Pneumatic Cylinder

SMC AF40-N03B-Z-A-X2141 is a mist separator in SMC's AF-series air filtration line, designed to remove oil mist and moisture from compressed air before it reaches downstream components. It has a 3/8 NPT port size, body size 40, a manual drain, and a polycarbonate bowl that provides visual indication of condensate. Threaded for NPT connections, the unit weighs about 0.38 kg and is intended for inline installation in standard pneumatic circuits. By separating entrained liquid and aerosols from the air stream, it helps protect valves, cylinders, and actuators from contamination, extending service life and improving system reliability. Common applications include automation lines, packaging equipment, and general manufacturing where clean, dry air is critical for predictable performance of cylinders, sensors, and control valves. As part of the AFM/AFD mist separator family, the AF40-N03B-Z-A-X2141 offers a compact footprint suitable for tighter installations while providing straightforward maintenance through its manual drain and accessible bowl.
