IAC has more than five decades of experience in the design and manufacture of silencers for jet engines, gas turbines, forced draft fans and air handling systems. The result is an extensive range of standard silencer configurations incorporating innovative design and manufacturing features with performance certified in IAC’s Aero-Acoustic NVLAP-Certified Laboratory. 

Performance ratings for both Dynamic Insertion Loss and Aerodynamic Pressure Drop for all Power-Flow Silencer designs have been certified in accordance with ASTM E477 and applicable sections of ISO 7235:1991 and British Standard 4718-1971 in our full-scale wind tunnel and corroborated by independent laboratories.

Some typical applications for Power-Flow Silencers include:

…any Air/Gas Handling Installation

IAC Power-Flow Stack Insert Silencers are available in 28 standard aero-acoustic designs to solve most stack noise problems. Special designs are developed in the IAC Aero-Acoustic Laboratory as may be required.

Cost-Effective Silencing for Induced Draft Fan Systems:

IAC Power-Flow ACoustic FIlter (ACFI) – Tuned Dissipative Silencers

IAC ACFI Silencers are designed to provide noise control for induced draft fans in power plants, ventilation system in steel mills, coal mines, aluminum reduction facilities, and other processes that involve gas streams which often contain appreciable amounts of moist particulate which can quickly clog and render conventional parallel baffle absorptive silencers ineffective.

Take advantage of IAC’s know-how…the most extensive in the noise control industry. Special silencer configurations are available to satisfy the most stringent criteria.
