Spark Traps for Quick-Disconnect Duct

Reduce the risk of fire by snuffing out sparks before they get into your dust collection system. These traps slow down and rotate airflow so sparks are extinguished before exiting. They’re commonly used in systems that collect material from metal grinding and welding.

Powder-Coated Steel—The finish adds a layer of protection against corrosion and wear from moisture, heat, and abrasive dust.
