SMC AN120-M5 – M5 Pneumatic Silencer, Sintered Body Noise Reducer

✅ SMC AN120-M5 is a pneumatic silencer from the AN Series, designed to reduce exhaust noise generated when compressed air is discharged from pneumatic valves and compact automation equipment.

✅ The AN120-M5 features an M5 threaded connection, making it suitable for miniature solenoid valves, small pneumatic valves and compact pneumatic mechanisms.

✅ The silencer uses a BC sintered copper-alloy body, providing a porous structure that helps diffuse exhaust air and reduce noise while maintaining a compact installation size.

✅ The AN120-M5 provides approximately 18 dB(A) noise reduction, an effective area of approximately 5 mm² and sonic conductance of approximately 1 dm³/(s·bar). Recommended flow is approximately 0.4 m³/min (ANR) or less, depending on operating conditions.

✅ The silencer can operate with compressed air up to approximately 1.0 MPa. The series is suitable for ambient and fluid temperatures of approximately 5 to 150°C, provided freezing does not occur.

✅ With a weight of approximately 3.4g, the AN120-M5 is suitable for applications where noise reduction is required without significantly increasing the size or weight of the pneumatic assembly.
