LOW PRESSURE DROP
IEC Low Pressure Drop Silencers use a straight-through design for maximum flow efficiency, moderate noise control, and minimal system resistance.

Industrial Exhaust Components offers low pressure drop silencers designed for maximum flow efficiency with minimal acoustic resistance. These straight through silencers allow exhaust gases to pass directly through the body without any internal flow reversal. The result is a pressure drop only slightly greater than that of an equivalent length of straight pipe.
​
This design is ideal for systems where low backpressure is a top priority. Common applications include high output engines, turbocharged systems, or installations that are sensitive to flow restrictions. While these silencers provide moderate noise attenuation, they are best suited for environments where flow performance and pressure efficiency are more critical than maximum sound reduction.
​
Key features include a smooth internal flow path, durable construction for high temperature exhaust systems, and compatibility with a range of inlet and outlet sizes. These silencers are available in carbon steel or stainless steel and can be customized to meet your specific installation requirements.
Side connections are generally not practical for this design, as they can significantly increase both pressure drop and manufacturing cost.
