Optimal Noise Control for Larger HVAC Systems

The SD-200-900 is perfect for large ventilation systems, offering high-performance noise reduction with a perforated inner core and a 50mm layer of high-density acoustic mineral wool. Its extended length makes it particularly effective in environments that require advanced soundproofing, such as large homes, offices, and commercial spaces.

Flexible Installation Options Backed by Expert Knowledge

Designed for ease of use, the SD-200-900 can be installed at any point within your ventilation system. For maximum noise reduction, professionals recommend placing the silencer downstream from an air handling unit (AHU) or extractor fan. For additional noise control, you can install a second silencer upstream.

Reduce Cross Talk and Improve Privacy

With its superior noise reduction capabilities, the SD-200-900 also helps prevent cross talk—unwanted sound transmission between rooms through shared ducts. This feature is especially valuable in:

• Offices: Improve privacy by minimizing noise transfer between meeting rooms, workspaces, and open-plan offices.
• Residential Spaces: Eliminate noise transfer between rooms or units in multi-family homes or apartment complexes, ensuring a more peaceful living environment.

Ideal for Large Residential, Office, and Commercial Spaces

• Homes: Achieve a quieter living environment by reducing HVAC noise in larger spaces such as bedrooms, home offices, and living rooms.
• Offices: Minimize background noise from ventilation systems, helping to improve focus, productivity, and comfort in large offices.
• Commercial Spaces: Provide a more comfortable and enjoyable atmosphere for customers and employees by controlling HVAC noise in retail stores, restaurants, warehouses, and other commercial settings.

Additional Benefits of the SD-200-900

• Air-Tight Sealing: Equipped with rubber-sealed connections, the SD-200-900 prevents air leakage, ensuring that your system remains efficient and effective while reducing energy consumption.
• Fits Standard Ductwork: The SD-200-900 is designed to integrate seamlessly with standard 200mm ducts, allowing for easy installation in new or existing ventilation systems.
