Characteristics

The SONIE BS+ is a high-performance acoustic splitter designed for ventilation and air handling ductwork systems. It effectively reduces noise generated by HVAC installations.

Its reduced weight compared with a standard acoustic splitter improves on-site handling and installation. This weight reduction also makes it possible to optimize splitter dimensions, increasing the overall attenuation performance of the silencer.

Characteristics

  • DX51+Z275 galvanized steel frame
  • Rounded aerodynamic profile
  • Mechanical reinforcement by ribbing
  • High-performance glass wool insulation
  • Insulation density: 24 kg/m³ ±10%
  • Fire classification: A2-s1,d0 (M0)
  • Anti-fibre-release glass veil protection
  • Available thicknesses: 50 / 100 / 150 / 200 / 300 mm

Performances

  • Acoustic performance
    • Tested in an independent laboratory in accordance with EN ISO 7235
    • Acoustic improvement of up to +15 dB at low frequencies compared with standard insulation
  • Pressure loss
    • The rounded frame profile can reduce pressure losses by up to 30% compared with a straight-edge profile in certain configurations

Mechanical robustness

    • High-strength steel frame ensuring stability, long service life, and proven mechanical performance validated through testing

Applications

  • Commercial ventilation systems
  • Air handling units (AHUs)
  • Industrial ventilation systems
  • Technical rooms
  • Installations requiring high acoustic attenuation
  • Ductborne noise control
  • Low-frequency noise treatment in HVAC systems
