Series: SA-GB-20
Construction: Galvanized Steel
Application: Low Leakage
Sound attenuators are devices used to attenuate loud noises.The square and rectangular type attenuators are designed for handling maximum air capacities at minimum pressure drop. The attenuators can operate at velocities upto 1600 fpm (8 m/sec.) and 2" w.g. (500Pa) pressure. They are installed vertically or horizontally and rated for airflow and leakage as per DW-144 class C.
The shell noise radiation is minimized by double skin splitter construction and turbulence of the airflow is minimized due to the bell nose design of the splitter at the entrance of the air inlet.
Better results are obtained by using BETEC CAD factory calibrated and fabricated Sound Attenuators.
