Ventilation Attenuator/Silencers
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.
Ventilation Attenuator Applications:
- Enclosure air inlet system
- Hot air exhausts system
- Boiler/HRSG fans
- Turbine inlet/outlet systems
- Marine Engine room fans
The Design Criteria are:
- Cross sectional size for the required air flow.
- Attenuator length to achieve required noise reduction
- Air way width and length to achieve required pressure drop
- Splitter thickness to absorb noise waves
Key Features
- Also known as Splitter Silencer or Baffle Silencer.
- Low Back Pressure achieved by minimal flow restriction.
- Used for ID/FD/SA Fans, Ventilation Fans, Exhaust Fans for noise reduction.
- Manufactured in Carbon Steel, Stainless Steel with Acoustic Infill.
- Can be added to existing installations.
