Aug 16, 2021 · Pneumatic mufflers, or otherwise known, silencers, quietly and safely vent pressurized air into atmosphere on an air compressor. This article will provide you with all the relevant information about them for you to gain a better understanding. Table of Contents. What Are Pneumatic Mufflers? Pneumatic Muffler Materials. Pneumatic Muffler Sizes.
May 26, 2020 · Pneumatic mufflers, also called silencers, safely and quietly vent pressurized air to atmosphere. They are commonly installed on air valves, cylinders, manifolds and fittings.
Oct 25, 2023 · Pneumatic silencers are strategically placed within the system to disrupt and absorb these sound waves, reducing noise levels. With this in mind, pneumatic silencers operate through two primary mechanisms: absorption and diffusion. Absorption: This mechanism involves sound-absorbing materials often placed within the silencer.

A Pneumatic silencer’s function is to vent pressurized air after it has performed work at a safe noise level and to prevent contaminants from exiting (if it is combined with a filter). Excessive noise may be produced as the pressurized air is released to the environment. Noise is the result of turbulent air which is produced when the fast-moving ai...
Pneumatic silencers are designed in differing shapes depending on the application. Application specifications that influence design are housing materials, working temperature ranges, working pressure range, and connection options. Additionally, silencers can be specified with a filter to prevent contaminants (i.e. oil) from being discharged into th...
Material
Silencer housing material should be selected according to application. Housing material will influence the silencer strength, environment compatibility, pressure range, and temperature range. The housing material should be considered carefully during selection. The most common housing materials are sintered brass, sintered plastic, and stainless steel.
Temperature
Silencers are suitable for high or low temperature applications. Material should be specified appropriately, especially in extreme temperatures. During selection, ensure the silencer material can operate correctly across the entire operating temperature range of the application.
Pressure
Pneumatic silencers are specified with an operating pressure. The silencer should be selected in accordance with the correct operating pressure to ensure optimal noise reduction and reduce premature failure. The surface area of the silencer is dependent on housing material and shape. Surface area will impact the overall size, mechanical strength, and noise reduction of the silencer. Additionally, the resulting back pressure during operation will prevent proper machine operation if not selecte...
Throttle valves are commonly included with silencers and are commonly just called adjustable pneumatic silencers or flow control silencers. Adjustable pneumatic silencers are an inexpensive method for pneumatic flow control to control the speed at which air exits the valve. For example, by controlling the exhaust speed of a pneumatic cylinder you c...
Silencers can also contain a filter to remove oil mist and dust in the exhaust air from entering the environment. These are important if the pneumatic air is dirty or toxic to allow you to protect the environment, workers, and/or applications if working in a sterile environment. Figure 9 shows an example of a silencer exhaust cleaner.
To protect workers from exposure to harmful noise and toxic substances levels, organizations and governments define standards for machine manufacturers. Pneumatic silencers are commonly certified to the following standards: 1. Pressure Equipment Directive(PED)- 2014/68/EC 2. Restriction of Hazardous Substances (RoHs) - 2002/95/EC 3. Registration, E...
Pneumatic silencers can be applied in many applications. Applications which operate pneumatics at a high frequency and produce a large amount of noise are well suited for pneumatic silencers. The application examples below commonly use pneumatic silencers. 1. Robotics:Robotics frequently use pneumatics to control movement or perform work on a load....
What is the difference between a silencer and a muffler?
A pneumatic silencer and pneumatic muffler refer to the same device. The term silencer is commonly used in British English, whereas the term muffler is commonly used in America.
Will I ever need to clean my silencer?
It is recommended to routinely clean silencer threads and the housing exterior depending on usage. Dirt and dust can build inside the threads or housing of silencers, especially in polluted exhaust environments. This prevents damage from blockages and reduces the possibility of downtime.
How can I ensure my silencer remains tight?
Depending on the frequency and pressure requirements of your application. A sealant can be applied to the thread of the silencer to ensure it remains tight during operation.
Jan 29, 2024 · In your pneumatic systems, the silencers are also referred to as mufflers, the functions of which are to vent the compressed or pressurised air into the open air. In the industrial setting, a pneumatic silencer will be installed either on the cylinder, fittings, or solenoid valves.

What are the different types of pneumatic silencers?
A Festo silencer, for example, is a body/sintered body that uses several chambers separated by baffles to slow down and cool down the escaping gases of the projectile. This leads to a reduction of the orifice blast and fire of the silencer.
