Dust Collector Bags: Sparks

Sparks, live particles or burning embers can wreak havoc in any baghouse. Fires, explosions and damaged dust collector bags usually result. Synthetic fibers, whether thermoplastic like polyester or non-flammable like aramids, can melt, degrade, catch fire or pyrolyze when a burning particle is driven onto the surface of a filter media, supported by the draft of the fan.

Solutions include:

BWF CS30/31 for light sparks
FireGuard^® for light to medium sparks
Pyroguard^® for medium to heavy sparking

Designs such as FireGuard protect the base filter media with a top layer of spark resistant fibers. PyroGuard is a unique surface coating containing graphite to protect against sparks and pyrophoric dusts. CS30/31 are PTFE coatings which are effective against light sparks.
At best, these finishes will only mitigate a severe problem and prevent a small problem from causing a major fire. Mechanical solutions and fire suppression systems are the most complete approaches to sparks, embers or live particles.
