Ventilation Attenuator/Silencers are also referred as Splitter Silencers or Baffle Silencers. The Ventilation Attenuators/Splitter Silencers are typically installed to reduce noise emitted by the ventilation systems, components like axial fans, ventilation blowers, ID/FD/SA fans, AHU’s etc. These attenuators can be installed in either existing duct (circular/rectangular/square) or cones as an additional element with the housing/casing.
