Pneumatic Silencers

Pneumatic silencers are used in pneumatic systems to safely vent pressurized air to the atmosphere. Also known as mufflers, they are typically used with valves, manifolds, cylinders, compressors, and fittings. Pneumatic Resources offer a range of high-quality silencers from the leading brand, SMC.

Why would I need a pneumatic silencer?

Vented air that exits from an exhaust port can be so powerful it produces noise loud enough to be harmful to the environment or workers. Additionally, the exhausted air can contain contaminants that may clog pneumatic systems. A silencer is a cost-effective solution used for noise reduction and to prevent unwanted contaminants from entering the system.

How does a pneumatic silencer work?

Silencers are installed directly into the exhaust port of pneumatic valves and equipment. They work by diffusing the released air over a larger surface area, which reduces turbulence and decreases noise levels.

What are the different types of pneumatic silencers?

The two most common types of silencers are conical and flat. Both designs come with various working pressure and temperature ratings, connection types, and housing materials including metal and plastic. The specific application will influence which type of silencer is selected.

Housing Materials

The housing material should be carefully considered based on your application and environment. Common materials include sintered brass, sintered bronze, and stainless steel.

Connection Types

Most pneumatic silencers have a threaded male connection, or alternatively, a push-in hose connection. Thread standards include BSP (British Standard Pipe), which can be BSPP (parallel or G) or BSPT (tapered or R). Other thread types include NPT (National Pipe Thread) and Metric sizes such as M3, M5, and M7.
