HVAC attenuators are acoustic silencers to reduce the noise transmitted through air ducts and through openings for the ventilation of enclosures and industrial buildings. Generally mounted within the system’s ductwork, they ensure that a specific noise criteria is achieved within the internal or external areas they are installed in.

In heating, ventilation and air conditioning (HVAC) systems, attenuators are often needed to reduce the noise from mechanical sources, such as fans and turbulent air flows. They are used to ensure that the noise does not exceed the room’s specified noise rating (NR) level. HVAC duct attenuators are available in a range of sizes and models, both rectangular and circular, which can be selected to reduce noise to meet your required levels.
