CYLINDRICAL SILENCERS
IEC Cylindrical Silencers are available in a complete range of grades from Industrial to Super Hospital Plus, built for compliance, durability, and performance.
For our silencer selection purposes, there are four factors that influence the sizing of silencer:
-
Engine exhaust flow – CFM
-
Exhaust temperature – Degrees F
-
Allowable backpressure – inches of H2O
-
Attenuation required - dBA
The proper selection and size of the engine silencer is of critical importance to ensure that pressure drop and attenuation performance are met. Our experienced staff will work with you to ensure you get the best results as we offer 7 different grades of silencer which enables us to meet your attenuation needs.
All Industrial Exhaust Components internal components of our silencers are engineered to minimize resonance and vibration induced fatigue.
Construction
Standard units include heavy duty 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
14 to 20 dBA Noise Reduction
​
A rugged silencer built for commercial and industrial settings, effectively controlling exhaust noise where background levels are high.
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
45 to 60 dBA Noise Reduction
​
Top-grade silencer engineered for maximum attenuation in ultra-low noise environments, using reactive and absorptive design for critical applications.
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.
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.
25 to 35 dBA Noise Reduction
​
Engineered for residential areas with low background noise, reducing exhaust levels to align with surrounding ambient conditions effectively.
35 to 50 dBA Noise Reduction
Hospital Plus silencer engineered for very low ambient noise, combining reactive and absorptive features for stationary and mobile power applications.
