Exhaust & Blower Silencers

Cowl Spiral Chamber Silencers  

Cowl® silencers are available in Residential and Critical grades. Factory customization is also available to fit your specific silencing needs.

Cowl® silencers feature a unique single spiral chamber design that allows a free flow of exhaust gas through a uniform cross-section throughout the entire spiral chamber. As the exhaust gases pass through the spiral chamber, exhaust noise is progressively attenuated. The benefits of the Cowl® spiral chamber are high sound attenuation, very low exhaust back pressure and a very small package size. Typically, Cowl silencers are approximately 1/3 the physical size and ½ the weight of conventional cylindrical silencers, of similar performance.

Exhaust & Blower Silencers

Cowl® silencers are available in Residential and Critical grades.  Factory customization is also available to fit your specific silencing needs.

The TS Series Cowl Silencers feature Residential grade attenuation (22 – 28 dBA) in sizes from 1” up to 12” inlet diameter. Aluminized steel is standard construction and stainless steel in 304, 316 and 321 grades are available as an option. Cowl silencers are available in several standard inlet/outlet configurations as well as standard choices for various connection types.

The TXS Series Cowl Silencers feature an extended spiral chamber design which results in Critical grade sound attenuation performance in the 28 – 33 dB(A) range. The TXS series are also available in several inlet/outlet configurations and various connection types.
