Spark Arrestor protects against dust collector fires.

Adding protection to Gold Series-® cartridge dust and fume collection systems, Spark Arrestor operates without perforations or screens to take control of sparks and channel them away from filters and into dust collector's hopper. Unit works by creating torturous paths that give sparks and embers time to lose energy as they are directed to safe area. Each module can handle max of 10,000 cfm, but...
