Engineered Acoustics’ dissipative rectangular and circular duct silencers are designed to offer superior acoustic and aerodynamic performance. Rectangular models utilize acoustical splitters, sometimes called baffles, for broad-band attenuation. Perforated metal protects the glass fiber from erosion by the airflow. Similarly circular models have acoustical center-bodies, sometimes referred to as pods. They also incorporate glass fiber external to the duct connection size.
Splitters in rectangular models vary in quantity and thickness, and air
passages also vary in size. Circular models vary in center body diameter,
air passage width and external body dimension. The splitters and center
bodies are aerodynamically shaped to minimize pressure drop.
