Spark Traps

Stop sparks before they become a problem. Also called spark arrestors, spark traps capture sparks from grinding, welding, and cutting before they reach your filters or baghouse.

Spark traps, or spark arrestors, protect your dust collector and downstream ductwork from sparks generated during grinding, welding, plasma cutting, and other hot-particle processes. Positioned upstream of the collector, they capture and eliminate sparks before they can reach the filter media or baghouse — reducing fire and explosion risk in combustible dust environments. Spark traps are a critical safety component for welding, metal fabrication, and woodworking facilities working under NFPA combustible dust guidance.
