Vibro-Acoustics, by Swegon Group Company products

Designated as “RD” for Rectangular Dissipative, this product line is designed to match straight rectangular ductwork connections and casing geometry.

Circular Dissipative silencers are labeled “CD” and are typically used with circular duct systems or inline axial fans.

When project space limitations cannot accommodate straight silencers, Rectangular Elbow Dissipative (“RED”) silencers can be used to both reduce noise and control pressure losses.

To save space and reduce project cost, any silencer can be designed to have different connections and casing geometry to match project requirements.

Axial Fan Silencers by Vibro-Acoustics have a conical design which provides reduced horsepower requirements and energy savings when aerodynamically matched to the fan inlet or outlet.

Addressing noise and vibration issues caused by rooftop units (RTUs) can be challenging. To target all potential noise problems, the complexity of the system must be considered.

Flat Blade Acoustic Louvers (up to 18” in depth) deliver an economical means of providing attenuation to low velocity air inlet or outlet openings, while minimizing a line of sight through the opening.

Airfoil Blade Acoustic Louvers (up to 24” in depth)—the louver design with least air resistance—provide attenuation to openings or enclosures for pressure drop sensitive applications.

V Blade Acoustic Louvers (up to 24” in depth) provide significant broadband attenuation to low velocity openings while minimizing a line of sight through the opening.
