Rectangular and Round Silencers

  • FläktGroup SEMCO also offers a wide-range of acoustic silencers engineered and independently tested to fit your application. Our silencers are designed to reduce noise primarily in heating, ventilating, and air conditioning systems.


    Silencer models are specifically designed to reduce noise in specific octave bands or across a wide range of noise levels. They are available in either a rectangular or round configuration, including straight flow models. They come in a wide range of performances and materials, and are available for either exterior or interior applications.


    Applications include heating, ventilating, and air conditioning; custom air handling units, generator enclosures, and exhaust stacks, manufacturing equipment and almost any other situation where noise pollution is a concern.

    This product is eligible for AVRON46® coating which provides proven protection to HVAC air duct systems where mold and other fungi are of particular concern.  To read more about this option, click here.
