A carbon steel mini-mill in the Midwest USA had an issue with sparks reaching their dust collector. The client required a solution that would protect their facility from a potentially catastrophic event in their dust collector that could result in untimely disruption of production, costly maintenance expenses, and potential losses in terms of lives and property.

Mill management turned to Micronics, as their proven partner in the supply of filter media, routine baghouse maintenance services, and proven technical expertise to evaluate their spark concerns and provide recommendations.


After a thorough site evaluation was performed by the Micronics Engineered Filtration team, a spark arrester or “drop-out” box was deemed the best solution for mitigating against sparks and embers reaching the baghouse dust collector.

A spark arrestor is a type of system modification that can be retrofit to an existing dust collector; it does not require as large a differential pressure drop to operate. Our modification was for a long-term solution. designed as a box-type chamber, with a baffle in the center, which was necessary to break down the dust particulate upon entry.


Micronics implemented a design that was efficient in removal of spark-laden, heavier particulate from the air stream, allowing the remaining particulate to continue on to the dust collector without risk of spark carry-over. The spark arrester configuration included an internal baffling arrangement. The spark arrestor was outfitted with a rotary airlock to allow continuous discharge of collected materials.

Evaluation, design, and supply helped to protect the customer’s facility and eliminate spark carry-over to this steel mill’s dust collector.
