The key role of silencers in ventilation

The key role of silencers in ventilation

Noise reduction is a major challenge for ventilation and air handling systems. Whether in commercial buildings, hospitals, laboratories or industry, acoustic requirements are becoming increasingly stringent.
Ventilation silencers reduce the noise generated by fans, air handling units (AHUs) or air networks, without compromising airflow or energy performance.

The SVR and SVC models developed by Groupe Boët meet these needs by combining acoustic efficiency, robustness and reliability.

These silencers can be adjusted to meet varying airflow rates, from low to high, depending on the specific needs of your installation. What’s more, different pressure drop options are available, enabling precise adaptation to the characteristics of the sound source.

From 10 to 40 dB (A)
Rectangular or circular design
High-temperature resistors
Standard or customized solutions
Optimized configuration
SVR and SVC ranges: solutions tailored to building and industrial needs

SVR and SVC ranges: solutions tailored to building and industrial needs

These two ranges enable optimum adaptation to the configuration of the air distribution network, guaranteeing both acoustic comfort and continuity of service.

SVR silencers: designed for rectangular ventilation networks, they fit easily into round ducts.
SVC silencers: suitable for circular ventilation networks, they offer maximum flexibility for installations requiring large cross-sections.

Typical building and industrial applications

Typical building and industrial applications

SVR and SVC silencers can be integrated in a wide range of contexts. In each case, the choice of model and dimensions depends on acoustic, aeraulic and regulatory constraints:

Tertiary buildings: offices, hotels, hospitals, shopping centers.
Industry: factories, workshops, production areas, laboratories.
Sensitive infrastructures: data centers, recording studios, clean rooms.
Hospital air treatment: operating theatres, intensive care units, areas requiring perfect acoustic control.
Acoustic performance and compliance with standards

Acoustic performance and compliance with standards

SVR and SVC silencers are designed and tested in accordance with the main acoustic and ventilation standards.
They ensure :

Noise reduction of up to 50 dB(A) depending on configuration.
Compatibility with European acoustic regulations and the specific requirements of HVAC design offices.
Laboratory-measured performance, guaranteeing reliable data transmission.

Integration into HVAC systems and ventilation ducts

Integrating SVR and SVC silencers is quick and easy:

Direct mounting in circular or rectangular ducts.
Several silencers can be combined to achieve the required performance levels.
Optimization of sizing according to flow rate, air velocity and dominant noise frequency.
This approach guarantees a tailor-made solution, optimized for each project.
