RECTANGULAR SILENCERS
IEC Rectangular Silencers combine reactive and absorptive technologies to control broad frequency noise while fitting into low-clearance areas.
Our rectangular silencers are a multi chamber reactive/absorptive silencers provide reliable noise attenuation from residential to hospital grade levels while also helping manage surface temperature through a double wall insulated design.
​
Ideal for use in engine rooms, packaged power systems, process skids, marine vessels, and military platforms, these compact disk silencers feature heavy duty welded steel construction and high temperature insulation that minimizes radiated noise and skin temperature. Standard units include ANSI 150 pound flange connections and a high temperature black paint finish. Custom options include dual inlets, stainless steel construction.
Construction
Standard units include carbon steel welded construction with high heat black paint. Sizes 6" and below come with standard ID/OD connections. Sizes 8" and above come standard with ANSI flanged connection. Additional connections are available please contact Industrial Exhaust for more details.

SILENCER GRADES
IEC- Residential
19 to 25 dBA Noise Reduction
​
Provides reliable exhaust noise control for stationary engines, marine power, and mobile equipment where only moderate attenuation is needed.
IEC-Hospital
35 to 42 dBA Noise Reduction
​
Hospital-grade silencer engineered for critical noise reduction in low ambient environments, suitable for stationa, schools, marine, and power.
IEC-Critical
25 to 35 dBA Noise Reduction
​
Engineered for residential areas with low background noise, reducing exhaust levels to align with surrounding ambient conditions effectively.
IEC-Super Critical
32 to 42 dBA Noise Reduction
​
​Engineered for quiet residential areas with very low background noise, providing super critical silencing where maximum attenuation is necessary
