Lindab ABJ062 SLU 400-900-100 Round Duct Silencer

The Lindab SLU 400-900-100 is a round duct silencer built to reduce airborne noise travelling through a ventilation system, sized for a 400mm nominal duct diameter.

• 400mm nominal duct diameter
• 900mm length
• Porous rubber acoustic insulation
• Pre-installed seal for faster fitting
• Rigid, non-flexible construction

Fitted into a round ductwork run, this silencer absorbs airflow noise generated by fans and air handling units before it reaches occupied rooms, and the pre-installed seal means installers don't need to source and fit a separate gasket on site during the ductwork run, saving time on installation day.
