SONIE BL

Description

The SONIE BL is an acoustic splitter specifically designed for cleanrooms and controlled-environment applications. It provides effective noise attenuation within ductwork systems while minimizing fibre release in sensitive installations.

Characteristics

• Galvanized steel frame with reinforcing ribbing
• Rounded aerodynamic profile
• Riveted or clipped assembly
• Monobloc mineral wool insulation
• Density: 50 kg/m³ ±10%
• Fire classification: A1 (M0)
• Anti-fibre-release glass fabric protection on both faces
• Available thicknesses: 50 / 100 / 150 / 200 / 300 mm

Performances

Acoustic performance
