Duct Silencers: Commercial - Industrial - HVAC

Silencers or Duct Silencers are an engineered product specifically designed to control airborne noise in ducts, openings in buildings, enclosures, or from equipment. They may also be referred to as industrial sound attenuators. Their noise reduction capabilities make them ideal for commercial use at hospitals, conference rooms, hotels and office buildings in which a silent environment is preferred. Our industrial silencers are custom engineered to meet the requirements of any application.

Spatial limitations, fan requirements and pneumatic pressure drops are all factors that call for particular attention when incorporating noise control products, including sound traps and duct silencers, into the existing system construction.

Some examples of duct silencers and their applications:

  • Acoustical Silencers - Reduction of sound reverberation
  • Gen-Set Silencers - Control noise produced by       generators/engines
  • HVAC Silencers - Sound attenuators for building ventilation systems
  • Sound Traps - Reduce sound volume from noisy machinery on the factory floor

Standard and Custom Duct Silencers
  • For projects that necessitate silencers that are larger than the maximum standard dimensions (48" x 48"), we carry rectangular duct silencers. These can be fabricated as two separate standard silencers and constructed to fit the structure you are working with.
  • We also carry round duct silencers with features including but not limited to: galvanized  perforated sheet metal, spun head to reduce pressure loss, a pressure light casing.

Industrial Duct Silencers

Openings into or out of noisy environments are primary systems for the application of industrial duct silencers. These consist of utility rooms, building ventilation systems, etc. Imagine how difficult it would be to work in a conference room filled with the noise of a fan motor, or recovering from an illness in a hospital room only to be disturbed by the sounds from a loud duct right outside the window. Noise control measures, such as silencers, allow the air to flow freely from the necessary generators without the addition of any unwanted sound.
