Noise Control for Gas and Air Flow Systems
IndustrialAcousticsCompany- thepioneeringleaderinaero-acousticnoisecontrol- hasmore thanfour decadesof experience in the design and manufacture of silencers for jet engines, gas turbines, forced draft fans and airhandling systems. The result is an ex/ensive range of standard silencer configurations incorporating innovativedesign and manufacturing features withperformance certified in lAC's Aero-Acoustic NVLAP-Certified Laboratory.
Performance ratings for both Dynamic Insertion Loss and Aerodynamic Pressure Drop for all Power-FlowSilencer designs have been certified in accordance with ASTM E 477 and applicable sections of ISO 7235:1991and British Standard 4718-1971 in our full-scale wind tunnel and corroborated by independent laboratories.
Take advantage of lAC's know-how...the most extensive in the noise control industry. Special silencerconfigurations are available to satisfy the most stringent criteria.
RECTANGUlAR
...For applications ranging from highway tunnel andmineventilation to cooling tower silencing, rectangularparallel baffle silencers offer the greatest flexibility inoptimizing acoustical and aerodynamic performance.Catalog data is published for over 50 standard con-figurations. Request PFS Data Sheets
CYliNDRICAl
...For circular ducts/stacks and axial fan inlet and dis-
charge, tubular siiencers provide minimum turbulenceand pressure drop. Catalog data is published for over90 configurations. Request PFDS Data Sheets.
STACKINSERT
...For existing stacks in-serts provide economicaland effective sound at-tenuation. Stack insertsare available in traditional'bullet" designs, ACFI(ACoustic Filter) for dirtygas streams and parallelbaffle arrangements.Request Bulletin 4.0009
SIDEINlETANDINlETBOX
...For direct connection without transitions side inlet
and inlet box silencers save space and reduce cost.

...For turning sec-tions in otherwisewasted space com-pact silencers withcurved asymmetricalair passages optimizeaerodynamic andacoustical perform-ance.
STRAIGHT-THRULOWPRESSUREDROP
'...For material conveying systems and en-gine exhausts the straight-through designprovides sound attenuation with pressuredrops hardly more than the pipe section itreplaces.
SPECIAL
IU
...For limited space, tough acoustical andaerodynamic requirements and corrosiveenvironments lAC will develop special de-signs to suit.
Dissipative(Cylindrical shown) silencers provide broad-bandsound attenuation with absorptive fill materials protected by perforatedplates.
ACFI(ACoustic Filter - Rectangular shown) silencers use clog-resis-tant tuned cavities in contaminated gas stream processes that canquickly clog conventional parallel baffle silencers. Request Bulletin4.0010
Fiber-Free*(Rectangular shown) silencers are parallel baffle de-signs without fill of any kind. Access doors are provided so that baffleinteriors can be completely cleaned of contaminants.
lAC silencer design is based on state-of-the-art matrix-driven computational programs which minimizedesign time and eliminate costly field-performance deficiencies. However, in critical applications, it isessentialto demonstratesilencerperformanceinanaero-acousticlaboratorywithNVLAPaccreditation forthe ASTM E 477 Standard.
lAC's Aero-Acoustic Research Center permits forward- and reverse-flow dynamic-insertion-loss, self-noise, and pressure-drop rating of silencers and other characteristics in a closed-loop wind tunnel. Dual reverberation rooms permit testrng of system componentssuch as wall panels, doors, windows and assembled air handling units.
Customers, specifying engineers, and acoustical consuitants arealways welcome in the lAC laboratory. Contact us toarrange inspection and witnessedtesting programs.
