SMC Series AS Pneumatic Silencer & Exhaust Restrictor Function Fitting, 1/4 inches Inlet Connection size, 6mm Outlet Connection size - AS2301F-02-06SA


This pneumatic silencer & exhaust restrictor function fitting provides combined noise reduction and flow control for compressed Air exhausts in industrial systems. It connects to pneumatic lines via a 1/4 inches female R inlet and delivers controlled discharge through a one-touch 6mm outlet, operating within typical factory Air networks. The device is constructed from brass and polybutylene terephthalate to balance durability and lightweight performance while being suitable for general automation and control panels.

Features & Benefits


• Maximum operating pressure 1MPa enabling Compact system designs
• Proof pressure 1.5MPa enhancing short-term overpressure resilience
• Temperature range -5°C to 60°C allowing varied ambient use
• One-touch 6mm outlet simplifies tubing installation and removal
• 1/4 inches female R inlet supports common R-thread pipework
• RoHS compliance reduces restricted-substance concerns in assemblies

**Applications**


• Suitable for speed regulation on pneumatic actuators in automation
• Ideal for exhaust control on valve manifolds and pilot lines
• Used with control cabinets where Compact silencing is required
• Can be used for flow metering on Air preparation stations
• Used for noise reduction on pilot-operated cylinders in machinery

What materials comprise the body and what advantage do they provide?


The fitting uses brass for the main external port and polybutylene terephthalate for the functional silencer components, combining corrosion resistance with reduced weight and compatible wear characteristics for compressed air.

How does the inlet threading affect pipeline integration?


The female R-thread inlet matches common 1/4 inches R standard pipework, allowing direct connection to tapered BSPR fittings without additional adaptors for many installations.

What operating pressures are acceptable for continuous use?


Continuous operation is supported down to 0.1MPa and up to a maximum of 1MPa

temporary excursions may be tolerated to the 1.5MPa proof pressure but should be avoided for routine use.

How does the outlet Interface influence maintenance procedures?


The one-touch 6mm outlet permits Rapid tubing replacement and reduces downtime for routine line changes or reconfiguration, as push-fit removal requires only a simple collar depress.
