• High-Performance Soundproofing: This model features a high-density acoustic mineral wool layer that reduces noise by up to 15dB at 500Hz and 28dB at 1000Hz, ensuring a quieter environment.
• Durable and Safe: Constructed from robust galvanised steel and filled with fire-resistant mineral wool, the SD-125-600 meets all necessary safety standards and ensures long-lasting performance.
• Energy Efficient: The advanced noise attenuation design provides quiet operation without compromising the airflow, enhancing the efficiency of your HVAC system.

Custom Noise Control for Optimal Performance

The SD-125-600 effectively minimises noise with its perforated inner core and a 50mm layer of acoustic insulation, making it ideal for use in both residential and small commercial settings where quieter HVAC operation is necessary.

Easy Installation for Flexible Use

The SD-125-600 can be installed anywhere in your ductwork, though it is recommended to place it downstream from the air handling unit (AHU) or extractor fan for the best noise reduction. For additional noise control, a second silencer can be installed upstream.

Reduce Cross Talk and Enhance Privacy

The SD-125-600 also works well in reducing cross talk—sound transmitted through shared ducts. This is particularly useful in:

• Offices: Improve privacy between workspaces and meeting rooms by minimising noise travel.
• Homes: Reduce noise transfer between rooms or between apartments in multi-unit dwellings.

Ideal for Residential, Office, and Small Commercial Applications

• Homes: Eliminate HVAC noise to create a quieter, more comfortable living environment in bedrooms, lounges, and home offices.
• Offices: Reduce background noise, improving focus and productivity in the workplace.
• Small Commercial Spaces: Ensure a quieter environment for customers and employees in shops, cafés, and other small businesses.

Additional Benefits

• Air-Tight Sealing: Rubber-sealed connections ensure no air leakage, maintaining system efficiency and reducing energy consumption.
• Compatible Design: The SD-125-600 fits standard 125mm ductwork, making it easy to integrate into existing and new HVAC systems.
