What is a spark arrestor?

A spark arrestor is a device used to prevent sparks or embers from escaping from a chimney, exhaust pipe, or other openings in a structure. It is typically made of metal mesh or other heat-resistant materials and is installed at the top of a chimney or vent to trap any particles that could potentially start a fire.

Spark arrestors are commonly used in wood-burning stoves, fireplaces, and outdoor fire pits to reduce the risk of sparks igniting nearby combustible materials. They are also used on equipment that produces hot gases or exhaust, such as power generators, vehicles, and industrial machinery.

Regular maintenance and cleaning of spark arrestors are essential to ensure they remain effective in preventing sparks from escaping. Failure to maintain a spark arrestor can lead to a build-up of debris and potentially dangerous situations.
