Sound Attenuators
B-10, Galvanized Steel Construction.
Bell nosed splitters ; Low Leakage Rating.
Models: AS-B-10
AS B 10 Series 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 square and rectangular type attenuators are designed for handling maximum air capacities at minimum pressure drop.
The shell noise radiation is minimized by double skin splitter construction.turbulence of the airflow is minimized due to the bell nose design of the splitter at the entrance of the air inlet.economy results by using properly designed BETEC CAD factory calibrated / fabricated Sound Attenuators.
Sound Attenuators Cylindrical Type
B-30, Galvanized Steel Construction.
Bell nosed splitters ; Low Leakage Rating.
Models: CS-B-30
CS B 30 Series Cylindrical 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 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.
