What you will learn

• How the Sonic Series acoustic louvre SL4-10 controls airborne sound reduction in mechanical, HVAC and industrial applications within a 100mm system depth, achieving a Weighted Sound Reduction Index of Rw 18dB assessed to AS 1191:2002 (R2016) and rated to AS/NZS ISO 717.1:2004.
• The airflow performance of the SL4-10, including a 22% free open area, coefficient of discharge of 0.87, and Class 1 classification to AS 4740:2000, with pressure drop data across a range of operating velocities.
• How the SL4-10 balances three competing design requirements, acoustic attenuation, aerodynamic efficiency and weather protection, within a low-depth single blade configuration.
• Weather resistance performance assessed in accordance with AS/NZS 4740:2000, including a Class D rain resistance classification and average effectiveness of 0.744 across core velocities up to 3.5 m/s.
• Construction details of the SL4-10, comprising a steel frame, steel front blade, perforated steel rear liner and Rockwool acoustic infill with a powder-coated finish to nominated colour.
• Customisation options available for the SL4-10, including project-specific dimensions, colour finishes and integration with façade and plant screen systems.
