Noise Reducing Circular Ventilation Duct Attenuator Ventilation Silencer

Blauberg Duct Silencer – Best Noise Reduction for Quiet Ventilation

Boost the performance of your ventilation system with the Blauberg Duct Silencer, designed for superior noise reduction and cross talk attenuation. These silencers are ideal for reducing HVAC noise while maintaining smooth airflow, making them perfect for home, office, and industrial ventilation installations.

Key Features & Benefits

Wide Range of Size Options: Blauberg duct silencers come in a variety of sizes, fitting duct diameters from 100mm to 315mm, making them suitable for different ventilation systems in homes and businesses.
Different Lengths Available: Choose from 600mm or 900mm lengths to tailor the silencer to your specific space and noise reduction needs.
Effective Soundproofing: Each silencer contains high-density acoustic mineral wool to maximise sound absorption and minimise noise, providing a quieter environment in homes, offices, or industrial ventilation installations.
Built to Last: Made from durable galvanised steel and mineral wool.

Advanced Noise Reduction Technology

The Blauberg duct silencer uses advanced noise reduction technology. Air moves through a perforated inner core surrounded by a 50mm layer of acoustic mineral wool, effectively absorbing sound. This guarantees quiet operation while maintaining optimal airflow, making it an excellent choice for MVHR (Mechanical Ventilation with Heat recovery) systems, MEV (Mechanical Extract Ventilation) and any HVAC system.

Flexible Installation Options

Blauberg silencers are easy to install at any point in your ventilation ductwork. For the best performance, install them downstream from an extractor fan, heat recovery unit, or air handling unit (AHU). For extra noise reduction, you can add another silencer upstream to reduce inlet noise, ensuring maximum noise control throughout the system.

Reduce Cross Talk for Improved Privacy

Blauberg silencers are also highly effective at reducing cross talk, which is the transmission of sound between rooms via shared ducts. This is particularly useful in:

Offices: Prevent noise from travelling between meeting rooms or workstations, improving privacy and reducing distractions.
Homes: Stop noise transfer between rooms or flats in multi-family homes or apartment blocks, ensuring a more comfortable and private environment for occupants.
Hotels and Commercial Buildings: In hotels, hospitals, and other shared spaces, Blauberg silencers reduce cross talk to provide a quieter, more peaceful atmosphere for guests and clients.

Noise Control for Homes, Offices, and Commercial Spaces

The Blauberg Duct Silencer is a highly effective solution for reducing noise in a variety of environments, including:

Home Ventilation: Eliminate noise from your HVAC system to create a quieter, more comfortable living space in bedrooms, lounges, and home offices.
Office Ventilation: Reduce background noise from your ventilation system, improving concentration and productivity in work environments.
Commercial and Industrial Ventilation: Blauberg silencers provide noise control in large areas like shops, restaurants, and factories, creating a more comfortable space for employees and customers.
Apartment Buildings: Minimise sound transmission between units, ensuring a quieter and more private environment for tenants.

Additional Benefits

Air-Tight Sealing: Rubber-sealed connections ensure an airtight fit, preventing air leakage and maintaining system efficiency.
Fits Standard Ducts: Blauberg silencers are compatible with all standard duct sizes, making them easy to install in both new and existing HVAC systems.
Robust Design: Featuring durable galvanised steel and high-density, non-flammable mineral wool, these silencers meet all required safety standards and offer long-lasting durability.

Perfect for Homes, Offices, and Industrial Use

Upgrade your ventilation system with a Blauberg Duct Silencer for superior noise reduction, enhanced comfort, and long-term reliability. Whether you need to improve soundproofing in your home, office, or industrial space, Blauberg silencers are an excellent solution for creating a quieter and more energy-efficient environment.

Blauberg Silencer Noise Reduction Levels

The table below provides a comparison of noise reduction levels for various Blauberg Duct Silencer models, organised by octave-frequency bands (Hz). It details the decibel (dB) reductions at different frequencies, helping you choose the best model based on your specific noise control requirements.

Each model provides different levels of noise reduction depending on duct size (100mm to 315mm) and length (600mm or 900mm), ensuring optimal soundproofing for both residential and commercial systems.

Frequently Asked Questions

1. What is a duct silencer, and how does it work?

A duct silencer, also known as an attenuator, is a device used in HVAC systems to reduce noise generated by airflow or mechanical components such as fans. It works by channelling air through a perforated inner core, where noise is absorbed by high-density acoustic material (usually mineral wool). This reduces sound transmission without compromising airflow, creating a quieter environment in homes, offices, or industrial settings

2. Where should I install a duct silencer in my HVAC system?

For optimal performance, a duct silencer should be installed downstream of an extractor fan or air handling unit (AHU) in your ventilation ductwork. Installing an additional silencer upstream can further reduce noise, especially at the air inlet, providing comprehensive soundproofing for your system.

3. Can duct silencers reduce noise between rooms (cross talk)?

Yes, duct silencers are highly effective at reducing cross talk, which is the transfer of sound between rooms through shared ducts. This is especially beneficial in office buildings, apartment complexes, hotels, and other shared spaces where privacy and noise control are important.

4. How do I choose the right size duct silencer for my system?

To choose the correct size, measure the diameter of your ductwork. Blauberg silencers are available in a range of sizes from 100mm to 315mm in diameter. Additionally, consider the length of the silencer (600mm or 900mm) based on your noise reduction needs and available space. A longer silencer generally provides more sound attenuation.

5. Do duct silencers affect airflow in HVAC systems?

Duct silencers are designed to reduce noise without significantly affecting airflow. By using advanced noise reduction technology, they maintain optimal airflow while effectively reducing sound transmission. This makes them ideal for energy-efficient HVAC systems in homes, offices, and commercial buildings.

6. Are Blauberg silencers compatible with standard HVAC duct sizes?

Yes, Blauberg silencers are compatible with all standard HVAC duct sizes. They are easy to install and can be fitted into both new and existing systems without any major modifications.

7. How effective are Blauberg silencers at reducing noise?

Blauberg silencers provide high levels of noise reduction, particularly in the low-frequency range (e.g., 63 Hz to 250 Hz), which is common in HVAC systems. The exact reduction depends on the model and size, with decibel reductions ranging from 5 dB to 44 dB across different frequency bands

8. Are duct silencers necessary in residential homes?

While not always necessary, duct silencers are highly beneficial in residential homes, especially in areas where noise from HVAC systems affects comfort, such as bedrooms, living rooms, and home offices. By reducing noise, they help create a more peaceful living environment.

9. How long do Blauberg duct silencers last?

Blauberg silencers are built to last, with durable galvanised steel construction and fire-resistant acoustic mineral wool. They are designed for long-term use and come with a 5-year warranty, ensuring reliability and compliance with safety standards.

10. Can I install a duct silencer myself, or do I need a professional?

Installing a duct silencer can typically be done by someone with basic DIY skills, especially if the ductwork is already in place. However, for larger or more complex HVAC systems, or to ensure maximum noise reduction, it is recommended to have a professional install the silencer.
