SMC Series AS Pneumatic Silencer & Exhaust Restrictor Function Fitting, 1/8 inches Inlet Connection size, 8mm Outlet Connection size - AS2301F-01-08SA


This pneumatic silencer & exhaust restrictor function fitting is a Compact flow-control device designed for pneumatic systems where controlled exhaust and noise attenuation are required. It connects a 1/8 R female supply to an 8mm one-touch outlet, combining flow regulation with muffling to manage exhaust behaviour in automated and industrial installations.

Features & Benefits


• Maximum operating pressure 1MPa delivers consistent control under load
• Rated to 60°C supports elevated-temperature operation
• Proof pressure 1.5MPa provides margin for transient pressure spikes
• Minimum operating pressure 0.1MPa permits low-pressure modulation
• Brass and polybutylene terephthalate construction resists wear and corrosion
• RoHS compliance meets material-restriction requirements for installations

**Applications**


• Suitable for cylinder exhaust throttling in assembly automation
• Ideal for pneumatic panel installations requiring reduced noise
• Used for flow control on Air preparation units in production lines
• Can be used with pick-and-place equipment to adjust actuation speed
• Suitable for retrofitting into existing compressed-Air manifolds

What port genders are used for inlet and outlet connections?


The inlet accepts a female 1/8 R threaded connection while the outlet uses a male 8mm one-touch fitting for Rapid tube attachment.

How does the unit behave under low-temperature conditions?


It is specified to operate down to -5°C, maintaining flow-control characteristics within that temperature range.

Which materials are in contact with the medium and what are their roles?


The fitting combines brass for mechanical strength at the threaded inlet and polybutylene terephthalate for the one-touch outlet and internal components to balance durability and moulded precision.

Is the device suitable where brief overpressure events occur?


Yes, the 1.5MPa proof pressure provides a safety margin against short-term pressure excursions above normal operating pressure.
