CRITICAL GRADE CYLINDRICAL SILENCER
Expected 25 to 35 dBA Noise Reduction
The IECC Critical Grade Silencer provides stronger attenuation for sensitive areas where background noise is low and stricter sound limits apply. It offers greater attenuation than standard residential models, ensuring exhaust noise remains within acceptable limits in noise-sensitive areas.
​
Typical applications: Internal combustion engine exhausts in quiet residential neighborhoods, schools, healthcare facilities, parks, and other locations where noise levels must remain low.
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.
