SMC Series AS Pneumatic Silencer & Exhaust Restrictor Function Fitting, 1/8 inches Inlet Connection size, 8mm Outlet Connection size - AS2201FS-G01-08A


This pneumatic silencer and exhaust restrictor function fitting performs flow control and noise attenuation in compressed-air circuits, combining an exhaust restrictor with a silencing element for use in industrial automation and mechanical systems. It connects a female 1/8 inches R inlet to a one-touch 8mm outlet and is intended for in-line speed-control tasks where controlled exhaust and reduced noise are required.

Features & Benefits


• Maximum operating pressure 1 MPa enables controlled actuation speed
• Proof pressure 1.5 MPa provides margin for pressure transients
• Operating temperature range -5°C to 60°C maintains performance across conditions
• Minimal functional pressure 0.1 MPa ensures responsiveness at low supply pressures
• Brass and PBT construction resists wear while reducing component weight
• One-touch 8mm outlet allows Rapid tube connection for quick servicing

**Applications**


• Suitable for controlling cylinder retraction speed in pneumatic actuators
• Ideal for valve exhaust noise reduction on assembly-line tooling
• Used with Compact pneumatic cylinders in pick-and-place systems
• Can be used for flow control in machine-tool pneumatic circuits
• Suitable for retrofit installations requiring simple push-in connections

What connection types are provided for integration into existing pipework?


The unit accepts a female 1/8 inches R threaded inlet and delivers to a male one-touch 8mm outlet for push-fit tubing.

Which materials are in contact with the pneumatic medium and why does it matter?


The internal wetted parts use brass and polybutylene terephthalate, offering a balance of corrosion resistance and dimensional stability for repeated cycles.

How does the product behave under elevated pressure spikes?


It is designed with a proof pressure of 1.5 MPa, so short-term pressure excursions up to that level are within its structural capability.

What approvals support industrial integration and procurement?


The fitting meets multiple standards and approvals including UL, CE, RoHS, JIS B 8370 and relevant ISO certifications.

Are there any ambient limits for reliable operation?


The component functions reliably between -5°C and 60°C, accommodating typical factory and plant environments.
