1.1. The swirl-type spark arrestor is suitable for processes that may generate sparks or hot particles, including laser cutting, robotic welding, metal cutting and grinding.

1.2. It can also be used as a pre-separation device in selected foundry, steelmaking, smelting and biomass-processing applications. A rotary airlock valve can be added for continuous particle discharge where required.

1.3. Sparks and hot particles generated by industrial processes may travel through the exhaust duct toward the dust collector.

1.4. The spark arrestor is installed upstream of the dust collector to help reduce the number and energy of sparks and hot particles reaching the filter system.

1.5. Reducing the amount of sparks and hot particles reaching the filter media can help reduce the risk of filter damage in suitable applications.

1.6. Protecting filter bags and filter cartridges from excessive hot-particle exposure can help maintain filtration performance and reduce unnecessary filter replacement.

1.7. The spark arrestor can be customized according to the duct diameter, with inlet and outlet dimensions matched to the connected ductwork for convenient installation.

1.8. The internal flow path and geometry are designed to create rotational airflow and promote particle collision and separation before the airstream enters the downstream dust collector.
