Spark Arrestor protects against dust collector fires.

Adding protection to Gold SeriesÂ-® 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,...

Spark Arrestor Can Prevent Diesel Engine Fires

Chalwyn Spark Arrestors developed specifically to prevent the risk of fire from the ignition of flammable materials caused by spark emission from the exhausts of diesel engines are now available from Chalwyn distributors. This risk can be so high that site access is often barred unless arrestors are fitted and many countries have legislation to that effect. The danger is greatest where carbon can...
