CYLINDRICAL TYPE CROSS TALK SOUND ATTENUATOR
BETEC CAD’s B-30 Series Galvanized Steel/Stainless Steel Construction.Cylindrical Type Cross Type Sound Attenuator.
Bell nosed splitters; Low Leakage Rating.
CCST B 30 Series Cylindrical type cross talk Sound attenuators are galvanized steel construction high performance, to ensure lowest resistance to airflow in HVAC systems with velocities to 1600 fpm (8 m/sec.) and at 2” w.g. (500Pa) may be installed vertically or horizontally and rated for airflow and leakage DW-144 class C. The standard construction is suitable for a leakage of <0.5%. The cylindrical type attenuators are designed for handling maximum air capacities at minimum pressure drop. Cylindrical type cross talk Sound Attenuators are installed in the duct work between spaces, which must provide noise reduction of air borne noise to at least match the sound transmission loss of the separating structure.
The cylindrical type Attenuators can be used where there is a demand for large amount of low frequency attenuation.models of Sound Attenuators are shorter in length, smaller in cross-section and easy to install at site.
