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. RS offer a range of high-quality silencers from leading brands including Festo, SMC, Legris IMI Norgren and of course RS PRO.

### Why would I need a pneumatic silencer?

Vented air that exits from an exhaust port can be so powerful it can produce a noise loud enough to be harmful to the environment or workers. Additionally, the exhausted air can also contain contaminants during operation. A silencer is a cost-effective solution used for noise reduction and to remove unwanted contaminants from clogging pneumatic systems.

### 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 via a larger surface area. This, in turn, reduces the turbulence and decreases noise levels.

### What are the different types of pneumatic silencers?

The two most common types of silencer are conical or flat. Both designs come in a range of different working pressure and temperature ratings, connection types and housing materials both metal and plastic. The application will influence the type of silencer selected.

**Housing Materials**

The housing material of your silencer should be carefully considered when making your selection, application and environment will influence this. There are various housing materials available, the most common being sintered brass, sintered bronze and stainless steel.

**Connection Types**

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

<p>Venting pressurised air from your pneumatic system can be a noisy process, so use a pneumatic silencer from Norgren to keep noise levels low.</p><h2>What does a Pneumatic Silencer do? </h2><p>The function of a pneumatic silencer is to minimise the noise caused by releasing pressurised air or gases. In areas where excess noise can be harmful, such as workplaces, it is crucial to reduce it to safe levels. It also makes for a more comfortable working environment for personnel. Additionally, a silencer can decrease the impact on downstream components from high-pressure air release (which would otherwise cause damage) resulting in a longer lifespan for your equipment.</p><h3>What are the benefits of brass silencers? </h3><p>Brass is a highly durable material, so brass silencers are well suited for use in challenging industrial environments across a wide range of applications. It is also corrosion resistant, so you can be sure of a long service life even in harsh environments. What's more, brass has great visual appeal which can make it a preferable choice compared to other materials, and it can be a more economical option than materials such as bronze.</p><p>Norgren have an excellent range of pneumatics components available here at RS so you can build and maintain a safe and efficient compressed air system. As a trusted global industry leader in precise motion control and fluid technology, you can rely on Norgren pneumatics products for high quality and performance.</p>

Norgren Pneumatic Silencers | RS

<p>Bring some peace and quiet to your compressed air system with Norgren pneumatic silencers. Here at RS Norgren have a great range of silencers to choose from, so you can find the ideal one to suit your needs. As an expert in the field of motion control and fluid technology, Norgren are trusted worldwide for their high-quality, high-performance products.</p><h2>What's a Pneumatic Silencer? </h2><p>When gas or air builds up in a compressed air system it needs to be safely vented to avoid damaging equipment. This process can be loud, and that's where a silencer comes in handy. A pneumatic silencer is a device which reduces the noise created when releasing pressurised air. They're often used in environments where it's vitally important to reduce noise levels, such as industrial areas where equipment is in close proximity to people.</p><h3>How does a Pneumatic Silencer work? </h3><p>This type of silencer is usually made up of one or more chambers, through which the pressurised air is directed. These chambers allows the fast-moving air to expand gradually, reducing its velocity and making it quieter and less turbulent. Porous materials such as foam or sintered metal are sometimes also used to further absorb sounds waves. The air is then safely expelled to the atmosphere.</p><h4>What's the difference between a Pneumatic Silencer and a Pneumatic Muffler? </h4><p>Both mufflers and silencers reduce noise levels of pneumatic equipment and these terms are often used interchangeably, although there are some differences. Mufflers are designed to dampen sounds caused by air flow in a pneumatic system, whilst pneumatic silencers are a more specific type of muffler. Silencers minimise the noise created from venting pressurised air.</p><p>Norgren's range at RS includes series such as the T20, T40, MB, and M/S. You can choose from units made of durable materials with porous properties such as plastic, brass, aluminium and bronze. Many of their silencers have a compact design and are lightweight to easily fit into your set-up. Some can be screwed directly into the exhaust port for quick installation, such as the M/S and T40 series. MA and MB series units are an ideal choice if you want high-flow capacity for heavy duty usage. They come with a brash mesh screen construction, cleanable element, and ensure improved flow and a longer life-span.</p>
