SMC Series AS Pneumatic Silencer & Exhaust Restrictor Function Fitting, M5 Inlet Thread, 4mm Outlet size - AS1201FS-M5-04A


This pneumatic silencer & exhaust restrictor function fitting is designed to control exhaust flow and reduce noise in compressed-air systems. It connects directly to an M5 inlet and provides a 4mm one-touch outlet for Rapid tubing attachment, offering a Compact solution for flow restriction and acoustic damping in automated and mechanical assemblies.

Features & Benefits


• Maximum operating pressure 1MPa delivers consistent control
• Proof pressure 1.5MPa increases safety margin during pressure spikes
• Operates from -5°C to 60°C for varied environmental conditions
• Inlet thread M5x0.8 with brass internal parts ensures secure connection
• Polybutylene terephthalate body for chemical and wear resistance

**Applications**


• Suitable for flow regulation on pneumatic actuators in automation
• Ideal for noise reduction in electronic test rigs and test benches
• Used with pneumatic control panels requiring Compact exhaust management
• Can be used for speed control on small cylinders in mechanical assemblies

What inlet and outlet interfaces does it provide?


It uses a male M5 metric inlet thread and a male one-touch 4mm outlet for push-fit tubing connection.

How does material selection affect performance?


The polymer body offers resistance to common pneumatic fluids while internal brass components provide Durable sealing at threaded connections.

What environmental limits should be observed during installation?


It is rated to function down to -5°C and up to 60°C, so installations outside that range may affect performance.

Are there any regulatory restrictions to consider?


The component conforms to RoHS requirements limiting hazardous substances in its construction.

How does the device manage sudden pressure excursions?


It is specified with a proof pressure of 1.5MPa, providing a margin above normal operating pressure to tolerate transient overpressure.
