SMC Series AS Pneumatic Silencer & Exhaust Restrictor Function Fitting, 1/4 inches Inlet size, 8mm Outlet size - AS2201FS-02-08SA


This pneumatic silencer & exhaust restrictor function fitting provides controlled exhaust flow and noise attenuation for pneumatic systems in industrial settings. It combines a brass body with polymer components to manage backpressure and reduce audible emissions while interfacing between a female R‑threaded inlet and a push‑in outlet on compressed Air lines.

Features & Benefits


• Operates across 0.1–1 MPa for adaptable flow control
• Withstands temperatures up to 60°C for routine industrial use
• Proof pressure rated at 1.5 MPa for transient pressure resilience
• Female 1/4 inches R inlet to 8mm male push‑in outlet for easy tubing connection
• Constructed from brass and PBT for chemical and wear resistance

**Applications**


• Suitable for machine tool exhaust flow regulation
• Ideal for pneumatic panel outlets in automation racks
• Used with compressed Air actuators for cycle speed control
• Can be used for noise reduction on cylinder exhausts

What connection types are required to install it?


The fitting accepts a 1/4 inches R female thread at the inlet and provides an 8mm one‑touch male outlet for push‑in tubing.

What materials contact the process Air and what advantages do they provide?


Brass and polybutylene terephthalate are used, brass offers robust metal sealing and PBT provides lightweight resistance to oil and typical contaminants.

How does it behave under short‑term pressure spikes?


It is proof‑tested to 1.5 MPa, allowing it to tolerate temporary overpressure above normal operating limits without failure.

Which approvals cover environmental and quality considerations?


It meets standards including CE, RoHS, ISO 9001, ISO 14001, CSA, JIS B 8370 and UL, reflecting compliance with recognised quality and environmental criteria.
