Chalwyn Spark Arrestors help mitigate the risk of fire from the ignition of flammable materials caused by spark emission from diesel engine exhaust. They are a basic but key safety feature for both hazardous area and lower risk diesel engine applications such as forestry or agriculture where a stray spark may cause ignition of combustible material.

Virtually all legislation with regard to operating a diesel engine in a hazardous area includes a mandatory requirement to fit a properly tested and approved exhaust spark arrestor.


  • Where spark emission from a diesel engine exhaust could lead to the ignition of flammable material
  • Offshore platforms and drilling rigs
  • Refinery vehicles and equipment
  • Forklift trucks in defined hazardous areas


  • Utilized globally in the oil and gas industry
  • A range of pipe diameter sizes available
  • Constructed from stainless steel 304L for corrosion resistance and longevity
  • Meets engine manufacturers' published back pressure specification providing emission conformance, good noise attenuation (SSL), and exceptional spark-arresting abilities
  • ATEX versions are available upon request and are safe to use in potentially explosive atmospheres. The 316L range meets EN 1834 requirements
