Aerodynamic Sound Attenuators
Computer Design & Selection Program
Features:
Modules Will Be Sized to Your X or Y Dimension, No Transition Required
Silencer Lengths Will Be Chosen To Suit Your Acoustic, Space and/or Pressure Loss Requirements - Automatically Selected by ASI Aeroacoustic Proprietary Computer Program
Splitters Can Be Aligned in Either the X or Y Plane to Minimize Pressure Drop Due to Inlet Flow Distortions
Silencer Combinations in Full Module and Half Module Increments for Large Areas/Ducts
Galvanized Metal Construction (Class I). For Heavier Construction (ASI Aeroacoustic Class 5), Massive Galvannealed Externals and Heavier Internals are Incorporated into Silencer
Example: Rectangular Modules
X & Y: Equipment/Duct Connection Size
L: Silencer Length Overall, Including Mating Connections, Each End
M: Module Dimension, or Multiples to Fit X & Y Dimensions, Acoustic and Aerodynamic Critera
G: Gap - Splitter/Gap/Length/Height Ratios Computer Iterated for Acoustics & Aerodynamics
