The key role of silencers in ventilation
The key role of silencers in ventilation
Noise reduction is a major issue in ventilation and air handling systems. Whether in commercial buildings, hospitals, laboratories or industry, acoustic requirements are becoming increasingly stringent.
Ventilation silencers reduce 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 circular ventilation networks, they fit easily into round ducts.
- SVC silencers: suitable for rectangular ventilation networks, they offer maximum flexibility for installations requiring large cross-sections.
