Spark arrester mufflers: acoustic performance and enhanced safety
This silencer combines an effective acoustic attenuation system with a mechanical device designed to retain sparks from exhaust gases. Thanks to its robust carbon or stainless steel construction and high-temperature anti-rust coating, it guarantees a long service life even in harsh environments.
With acoustic performance comparable to the standard models in the range, and a reduction of up to 30 dB(A), the spark arrester silencer offers a complete solution for industrial and energy sites subject to strict safety and environmental regulations.
Field of application
- Generator sets
- Cogeneration plants
- Urban and hospital zones
- Forest and agricultural environments
- Refineries and chemical plants
- Offshore and naval projects
Product features
The BOËT spark arrester silencer is designed to combine fire protection and noise reduction without compromising engine efficiency.
Its cylindrical design incorporates an internal mesh and specific geometry that effectively trap incandescent particles. Available from DN50 to DN600 and beyond, it adapts to a wide range of motor ratings. Versions from DN225 upwards feature integrated drains to facilitate deposit evacuation and simplify maintenance.
Thanks to standardized PN10 flange connections and radial or axial orientations, integration is rapid, even in confined environments such as containers or hoods.
