Trusted Supplier of Pneumatic Silencer in China

The pneumatic silencer is a cost-effective and easy solution to reduce unwanted noise levels and contaminants from pneumatics.

The pneumatic air exiting from the device produces noise that is harmful to the environment and workers. This air also emits contaminants.

In most industrial applications, the airflow exits at a constant velocity through an orifice which causes noise. The pneumatic silencer uses sintered bronze mesh to reduce noise.

You can use the pneumatic silencer to overcome the issue, preventing harmful contaminants from entering the system.

OSHA (Occupational Health and Environmental Control Agency) is the organization that has set the standards to help protect workers from harmful noise.

Figure 1 Pneumatic Silencer

The pneumatic silencer vent pressurized air and controlled and reduced the noise levels and contaminants from the system. The pressurized air causes excessive noise in the environment.

When the fast-moving air collides with the static air in the vent, it results in noise production.

You can install the pneumatic silencer at the exhaust port of the valve. It diffuses the pressurized air through a larger surface area, which reduces noise levels.

The pneumatic silencer has a porous material to increase the surface area. The pneumatic silencer has holes in it through which the compressed air is divided that increase the sound frequency to levels that are no more harmful to hearing.

The design of pneumatic silencers depends on their application and the type of application.

These designs have different housing materials, working temperature ranges, pressure ranges, and connection options.

You can customize the design of the pneumatic silencer with a filter to prevent contaminants from entering the atmosphere.

They have a throttle valve that can control the speed of the driving device.

There are various models of pneumatic silencers, and you can select one as per your requirements. For instance, air exhaust mufflers have a maximum working pressure of 125 PSI.

The relief valves silencer has a maximum working pressure of 116 PSI and is resistant to corrosive environments. Also, no maintenance is required in normal working conditions.

You can select the material of the pneumatic silencer according to the requirement of your application. The material is chosen based on environmental compatibility.

The most common materials are sintered brass, stainless steel, and sintered plastic.

If you are wondering for a low-cost option, then sintered brass is the best solution. It is suitable for non-corrosive and neutral environments.

Sintered plastic is also a low-cost and lightweight option, offering high chemical resistance to reduce noise.

Stainless steel is an excellent option for applications that need corrosion resistance and operation in a sterile environment.

Figure 2 Sintered Stainless Steel Silencer

You can use a pneumatic silencer in high and low-temperature applications. For high-temperature applications, choose the material carefully.

It is better to select a pneumatic silencer that can operate in different temperature ranges.

The silencer should be selected with the correct operating pressure to reduce noise. The surface area of the pneumatic silencer is determined by housing material and shape.

The surface area affects the noise reduction of the silencer.

The common cause of noise in most factories is a compressed air system and air blowing. The air turbulence leads to loud noise when the air expands freely.

If you control the turbulence, the noise will decrease. In compressed air, there are two sources of noise. First, noise from the air blast for cleaning, sorting, and transport; second, the venting valves’ noise is more aggressive.

The solution from these two sources of noise is a pneumatic silencer. It is proven scientifically that continuous exposure to noise higher than 90 dB causes deafness.

A pneumatic silencer is a great solution to evacuate compressed air from pneumatic systems to preserve hearing health. The pneumatic silencer also protects valves from contamination by dirt and other impurities.

Pneumatic silencer uses threaded end to connect to the ports. These ports can be a pneumatic solenoid valve or pneumatic cylinders.

Throttle valves, also known as adjustable pneumatic silencers, are attached with silencers to control the speed at which the air exits the valve.

By controlling the speed of the pneumatic cylinder, you can control the speed of the piston. The position of the screw can increase or decrease the size of the valve, and it holds the flow rate of air exiting the valve.

Each pneumatic silencer has an exhaust cleaner that removes oil and dust from entering the environment. It has a filter that removes any dirt in the exhaust air.

This is an essential part of the pneumatic silencer to ensure the silencer’s cleanliness and prevent toxic material from entering the environment.

The filter plays an important part to ensure that the pneumatic silencer has long product life. Polluted exhaust air keeps gathering dirt and oil mist which affect the performance of the pneumatic silencer.

A pneumatic silencer exhaust cleaner protects in providing a sterile environment.

The pneumatic silencer is used in many applications. In organizations, which operate pneumatics at high frequency and noisy environments, the pneumatic silencer is well suited.

In robotics, pneumatics controls the movement of the arm by opening and closing the pneumatic silencer and controlling exhaust noise.

The pneumatic silencer is also used on packaging machines to control motion. The signal from the controller activates the pneumatic device, which contains the noise.

The pneumatic silencer has applications in fence production machinery to protect workers from damaging noise.

A muffler is an American term that reduces the noise of the exhaust system. The pneumatic silencer is a British word that performs the same function of reducing excessive noise.

Both are mounted for the exhaust system and made from self-absorbing materials.

A muffler is a soundproofing device for reducing the sound of the engine. It consists of a chamber or pipes with holes in them.

The resonator is attached to the hole with air capable of producing waves that cancel the sound frequency.

Most pneumatic systems don’t require oil or lubricants, but the majority of them are lubricated. Lubrications reduce friction which improves efficiency and ensures high operating speed.

It also reduces wear and longer product life, but it causes discharge oil when the air exhausts.

The Occupational Safety and Health Administration (OSHA) provide standards to limit toxic substances. The simple solution to the noise problem is the pneumatic silencer that reduces noise and limits emissions of oil and dirt.

The pneumatic silencer complies with these standards.

The pneumatic silencer needs exterior cleaning by cleaning pollutants properly with the cleaning materials. There are many solvents commercially available that can thoroughly clean the pneumatic silencer.

Don’t clean them with the solvents having chlorinated hydrocarbons because it can damage the pneumatic silencer.

To clean the pneumatic silencer, first, soak the utensil in the solvent for a few minutes. Then scrub it using a nylon brush. Avoid using wire-brushed as they harm the silencer.

After scrubbing, blow the pneumatic silencer using compressed air.

A pneumatic silencer can vent pressurized air to the atmosphere. You can install it on air valves, cylinders, and fittings.

Without a pneumatic silencer, the loud sound of a pneumatic silencer can be harmful to the environment and workers—the noise results when fast-moving turbulent air collides with the static air.

The noise happens because of the factors like air density and velocity. So, the pneumatic silencer reduces the noise from pneumatic equipment by 15 to 35 dB(A).

The pneumatic silencers have various designs, such as cone, flat, and cylindrical shapes.

Pneumatic silencer offers many advantages to applications with a high noise atmosphere. The pneumatic silencer has versions and materials depending on the application.

A plastic pneumatic silencer with plastic fibres acts as a noise-reducing medium. The pneumatic silencer leads to a lower risk of hearing damage, increased performance of labour, and a better working environment.

The pneumatic silencer is lightweight, economical, and provides high chemical resistance, with better noise reduction. Pneumatic silencer can handle temperature to about 200°F.

The pneumatic silencer is cost-effective to reduce noise levels and unwanted contaminants entering the system.

Figure 5 A Variety of Pneumatic Silencer Material

Two common types of a pneumatic silencer, conical and flat, are designed for different working pressure and temperature ratings. They have other housing materials of metal and plastic.

The housing material of the pneumatic silencer should be selected based on the environment and your application.

Most pneumatic silencers have threaded connections or hose-in connections. The pneumatic silencer has 40 microns with 300 Psig maximum, and temperature ranges from -65°F to 300°F.

The stainless steel pneumatic silencer has an SS316 base, SS316 sintered powder, and a temperature range from 35°F to 392°F.

Pneumatic silencer plays an essential part in reducing the sound. The sound is caused when the valve’s exhaust port ventilates air. A Pneumatic silencer can lead to downtime if they are not maintained and replaced when necessary.

The pneumatic silencer divides the compressed air through small holes and reduces sound levels.

The pneumatic silencer can reduce the sound level by 30-40dB (A). However, old silencers have to replace as the pneumatic silencer becomes clogged with dirt.

It is harmful because it risks enormous counter pressure if the filter gets clogged. Therefore, replacing the old ones with new pneumatic silencers is crucial.

Before selecting the pneumatic silencer, you have to consider three points. The airflow of the silencer must be equal to or greater than the flow of the device, which avoids air restriction.

Make sure that the airflow capacity of the pneumatic silencer is similar to the flow rate. In a highly corrosive environment, it’s rational to choose a pneumatic silencer with stainless steel or plastic.

Thirdly, choose the pneumatic silencer according to the available space. For selecting the pneumatic silencer, consider the pressure of the air blast and the type of equipment.

Different pneumatic silencers do not have the same performance criteria.

Figure 6 Sizes of Pneumatic Silencers

When using the pneumatic silencer, it is difficult to see when it is blocked. Sometimes, it is challenging to identify blockage that creates problems for the operator.

A pneumatic silencer has a warning system. When the pneumatic silencer is blocked, the red line indicates that the silencer needs to be replaced.

Compressed air can cause high noise levels. The sound spikes can be harmful for short periods.

It is vital to reduce the sound levels as it makes a big difference for operators, as when the sound level decreases by 10 dB (A), it makes a drastic change.

You must consider the connection and pressure capacity while installing the pneumatic silencer. It is not essential to seal the connection thread on the pneumatic silencer.

The task of the silencer is to reduce the sound from the outer port. The silencer is easy to install, and you can install them by hand.

The outflow time in the compressed air system is affected by the volume and pressure. Silencers are designed for outlet ports on pneumatic systems.

The pressure at the silencer is not the same as supply pressure but lower. It would help if you chose a pneumatic silencer with extra flow capacity.

The pneumatic silencer can reduce the noise levels in various industrial applications. However, the exhaust ports of these valves must be protected from debris to prevent the pneumatic silencer from immature wear.

Bug screens are an effective way of protecting the ports by using wire mesh or gauze. There are loud discharges in large flow systems that over-cede the noise limits.

The silencers offer the bug screen with up to 70% noise reduction through the filter media.

The bug screen combines compact dimensions and corrosion resistance to provide optimum performance in harsh conditions.

Bug screen has the material of 316 stainless steel and is ideal for use in valve systems.

Many machines use the method of pressurized air as it is an efficient way of energy transfer. However, with the release of this air, the dB (A) reaches up to 100.

The noise depends not on the nozzle or tube but the air velocity. So, changing the size of the equipment is useless as it makes no difference, as where there is compressed air, there would be noise inevitably.

The pneumatic silencer is critical for the productivity of the equipment and to ensure a better working environment. It is essential to install a pneumatic silencer in all systems as noise control is part of US legislation.

The legislation includes The Control of Noise at Work Regulations 2005, Noise 2015, and The Environmental Noise Regulation 2010.

While pneumatic silencer contributes to controlling noise pollution and ensuring a safe working environment, the main problem with the silencers is the pollution in the piping causing’s clogs.

Oil is used as a lubricant to increase the pressurized airflow. This lubrication results in clogging. The contaminants and clogging pose a challenge.

According to the Health and Safety Executive (HSE), it is vital to maintain the quality of the pneumatic silencer.

You must purchase the pneumatic silencer with a noise reduction between 18 dB (A) and 25 dB (A). A Pneumatic silencer should not reduce the flow rate and maintain a flow rate even on polluted systems.

A pneumatic silencer must be strong enough to withstand the impacts of unexpected accidents. The last one is the maintenance of the pneumatic silencer.

It is an essential feature as the pneumatic silencer is neglected till they reach the critical point, so maintenance is crucial.

Figure 8 PTFE Plastic Silencers

A pneumatic silencer is an effective tool to reduce the sound level and facilitate maintenance. If you want to make your pneumatic silencer durable, you can attach the built-in indicators as they identify which silencer needs replacing.

However, another common problem associated with the pneumatic silencer is that filter or diffuser gets clogged by contaminants, leading to costly downtime, malfunctions, and risk of injury during operation.

To overcome this issue, you can install a movable internal diffuser that allows the silencer to set the optimum combination of flow capacity and sound reduction.

This will minimize operational disruptions, low back pressure, and noise suppression. It also ensures the long service life of a pneumatic silencer.

A standard sintered brass silencer is widely used to reduce the noise levels in pneumatic systems. It exhausts noise to industry-accepted levels of noise reduction and with minimum flow restriction.

You can use sintered brass silencers on valves, cylinders, air tools, and other systems as filters to resist dust and other contaminants from entering the system and causing valve failure.

The sintered brass silencer is made of brass powders and brass housing. A sintered brass pneumatic silencer is durable and has wide applications.

They have an operating pressure range of 0-10 bar, and the operating temperature range is -20°C to +60°C. The sintered brass pneumatic silencer has a 20-25 DB noise reduction capacity.
