What are pneumatic silencers?

Pneumatic silencers refer to specially engineered components designed to vent pressurized air while minimizing noise. They are generally used across applications that operate high-frequency pneumatics and are prone to excessive noises. Pneumatic 5/2-way solenoid valves and pneumatic cylinders often have pneumatic silencers installed in them.

Importance of pneumatic silencers

When pneumatic air comes out of an exhaust port, the difference in pressure and airflow can cause some noise. Besides noise, the air can also include containments, both harmful for the environment and workers. Pneumatic silencers are important and cost-effective solutions that ensure quieter operations and minimize exposure to pollutants in the working environment.

Best practices while buying pneumatic silencers

Before you buy pneumatic silencers, consider the following:

Material

When you are buying a pneumatic silencer, you should consider what material the silencer housing is made of. This is because the housing material will have considerable influence on the silencer strength, pressure and temperature range, as well as application compatibility.

The most common materials that you can go for are sintered brass, stainless steel and sintered plastic, depending on your needs. For example, if you want a low-cost option that offers long durability for non-corrosive environments, consider choosing sintered brass material. On the other hand, sintered plastic is a durable option that offers greater chemical resistance. Stainless steel housings, on the other hand, provide the most effective corrosion resistance and are suitable for sterile environments.

Temperature

The temperature at which your pneumatic silencer is going to operate is another important thing to consider. Before you buy a pneumatic silencer, make sure that it can operate across the entire temperature range of your application.

Connection type

Consider the connection type before buying a pneumatic silencer. They can be connected to different kinds of ports, including a pneumatic solenoid valve (5/2-way, for example) and a pneumatic cylinder, etc. Similarly, the thread that connects the silencer with the port can be different, like NPT (National American Pipe Thread), BSP (British Standard Pipe), or metric (ISO standards).
