Key Features & Benefits of the SD-315-900

• Superior Noise Reduction: The SD-315-900 delivers significant noise reduction, with up to 17dB attenuation at 500Hz and 30dB at 1000Hz. This makes it ideal for environments where maintaining a quiet atmosphere is essential, such as offices, homes, and large commercial buildings.

It meets all relevant safety standards, ensuring it can be trusted in both residential and commercial settings.
• Energy Efficiency: Designed to minimise noise without hindering airflow, the SD-315-900 ensures that your ventilation system runs smoothly and efficiently. This helps to maintain a comfortable environment while keeping energy consumption in check.

User-Friendly Design for Practical Use

The SD-315-900 is engineered for straightforward installation and use. Its perforated inner core, combined with a 50mm layer of acoustic mineral wool, provides optimal sound absorption while allowing for easy integration into new or existing ventilation systems. Whether you're a professional installer or a homeowner, this silencer is designed to make your HVAC system quieter and more efficient.

Flexible Installation for Custom Noise Control

The SD-315-900 can be installed at various points in your ventilation ductwork to address noise issues where they are most problematic. For the best results, professionals recommend placing the silencer downstream from an air handling unit (AHU) or extractor fan. If further noise control is required, an additional silencer can be installed upstream to provide comprehensive noise reduction across the system.

Reduce Cross Talk and Ensure Privacy

This silencer also helps to reduce cross talk, which is the transfer of sound between rooms via shared ductwork. The SD-315-900 is particularly effective in:

• Offices: Improve privacy by preventing noise from travelling between meeting rooms or workspaces through the ventilation system.
• Homes: Prevent sound transmission between rooms or apartments, ensuring a more peaceful and private living environment.

Ideal for Large Homes, Offices, and Commercial Buildings

• Homes: Achieve a quieter and more comfortable living space by reducing HVAC noise in bedrooms, lounges, and home offices.
• Offices: Minimise distractions by controlling background noise from ventilation systems, leading to improved productivity and focus in the workplace.
• Commercial Spaces: Ensure a more pleasant atmosphere for customers and employees by reducing HVAC noise in larger areas like shops, restaurants, and warehouses.

Additional Benefits of the SD-315-900

• Air-Tight Sealing: The SD-315-900 features rubber-sealed connections to prevent air leakage, ensuring maximum efficiency and helping to reduce energy costs.
• Standard Duct Compatibility: This silencer is designed to fit standard 315mm ductwork, making installation simple in both new and existing systems.
