Built to withstand the demands of continuous use, this silencer is ideal for both new and existing ventilation systems.
• Optimised Energy Efficiency: Engineered to minimise noise without disrupting airflow, the SD-250-900 helps maintain the energy efficiency of your ventilation system. This ensures smooth air circulation while keeping your system running effectively.

Designed for Practical Use

The SD-250-900 is engineered with the user in mind, offering straightforward installation and excellent performance. Its perforated inner core, combined with a 50mm layer of acoustic mineral wool, provides optimal sound absorption for quieter HVAC operations.

Easy Installation for Flexible Applications

The SD-250-900 can be installed at any point in your ductwork, depending on your specific noise control needs. For the best results, install it downstream from an extractor fan or air handling unit (AHU). For even more effective noise reduction, you can install an additional silencer upstream to ensure comprehensive sound control.

Reduce Cross Talk and Improve Privacy

The SD-250-900 is also effective at minimising cross talk—sound travelling through shared ductwork between different rooms or spaces. This feature is particularly valuable in:

• Offices: Improve privacy by preventing sound from travelling between meeting rooms or workspaces via the ventilation system.
• Homes: Stop noise transfer between rooms or apartments, ensuring a more peaceful and comfortable living environment.

Perfect for Homes, Offices, and Large Commercial Buildings

• Homes: Create a quieter, more comfortable home by reducing ventilation noise in areas such as bedrooms, lounges, and home offices.
• Offices: Reduce background noise from HVAC systems to improve concentration and productivity in workspaces.
• Commercial Spaces: Ensure a more enjoyable and peaceful environment for customers and employees in shops, restaurants, and large commercial spaces.

Additional Benefits of the SD-250-900

• Air-Tight Sealing: The SD-250-900’s rubber-sealed connections prevent air leakage, ensuring that your ventilation system remains energy-efficient and effective.
• Standard Duct Compatibility: This silencer is designed to fit standard 250mm ductwork, making installation straightforward in both new and existing systems.
