Industrial Silencers

Industrial Silencers for Fan Noise Reduction

VAW Systems manufactures industrial-grade silencers for noise control. We offer customizable silencer designs for intake and discharge air systems. Our silencers are compatible with virtually all axial and centrifugal fans and can be configured to fit almost any space. This allows us to integrate efficient silencers in practically any industrial or commercial space. 

Types of Silencers We Produce

Standard VAW Industrial Silencers: 

  • Rectangular Inlet Box (VRIB)
  • Rectangular Horizontal Box (VRHB)
  • Rectangular Side Inlet Box (VRSB)
  • Elbow Inlet Box (VEIB)
  • Circular Inlet (VCIBi)
  • Rectangular Discharge (VRDS)
  • Circular Discharge (VCIBd)

Custom Industrial Silencers are available for any pressure drop and space limited application, and installation with very low noise criteria.

VAW Systems’ Manufacturing Capabilities

VAW Systems’ extensive manufacturing capabilities mean we can design, engineer, and manufacture industrial silencers for almost any application. Our manufacturing can be scaled up for OEMs looking to integrate noise-reduction devices into their products. We have strong relationships with suppliers of various sound-absorbing materials; our knowledge of these materials and noise control means we can create noise-reduction products with rapid turnaround times.

Certification and Compliance

VAW Systems operates with strict quality assurance standards. It is ISO 9001:2008 certified, a CWB (Canadian Welders Bureau), and an AWS (American Welding Society) certified company.

What Is a Silencer?

Silencers and mufflers are used to control noise caused by various processes. Typically, silencers are used to reduce airborne noise caused by engines, generators, blowers, compressors, fans, and other devices. A variety of materials and designs are used to mitigate noise and keep businesses compliant with local noise ordinances. 

What Types of Industrial Silencers Are Available, and How Do I Choose the Right One?

We have a variety of different silencers available, including vent, stack, and compressor silencers. Choosing the right silencer depends on a number of factors, from the level of noise suppression needed to where the silencer will be placed. To determine which silencer is right for you, contact VAW Systems for a consultation.

How Effective Are Industrial Silencers in Reducing Noise, and What Reduction Levels Can I Expect?

Industrial silencers are designed for noise suppression; depending on the context in which they are being used, noise suppression levels can range from 15 decibels to a reduction of over 60 decibels in noise. 

How Effective Are Industrial Silencers in Reducing Noise, and What Reduction Levels Can I Expect?

Industrial silencers are designed for noise suppression; depending on the context in which they are being used, noise suppression levels can range from 15 decibels to a reduction of over 60 decibels in noise. 

Can Industrial Silencers Be Customized To Fit Specific Machinery or Space Requirements?

Yes. One-size-fits-all solutions don’t exist in this industry, as space requirements can vary significantly, and the type of machinery generating noise can dramatically differ; the amount of noise suppression needed will also vary. VAW Systems will work with you to customize a silencer to fit your precise needs. 

How Do I Determine the Correct Size and Specifications for the Silencer I Need?

The best way to determine the correct size and specifications for an industrial silencer is to work on a custom solution with your noise control engineer. They will ask for details about the kind of noise being suppressed, why suppression is needed, the dimensions of the machinery creating the noise, and surrounding vents, hoods, and other structures. 

The Fansil software selection tool is a quick and effective way to size a silencer that will meet your noise criteria, both occupational noise (nearfield) and property line noise (farfield).  Fansil is a free software that delivers product submittal drawings, materials options and overall weights.

What Is the Lifespan of an Industrial Silencer, and What Kind of Maintenance Is Required?

The lifespan of an industrial silencer varies depending on its application. Regularly inspecting, cleaning, and repairing your silencer can increase its lifespan. Depending on the materials used and their function, an industrial silencer may last anywhere from 5 to 20 years. 

Are There Any Legal or Regulatory Considerations I Should Be Aware of When Using an Industrial Silencer?

Industrial silencers are often used to comply with local noise regulation by-laws; being aware of these laws can help you select the right industrial silencer. Silencers must also abide by any safety codes governing the use of machinery.
