Combustible dusts are a recognized hazard for industrial facilities everywhere, and performing a hazard analysis is the best way to evaluate your risk of an explosion. In October 2015, the National Fire Protection Association published the new NFPA 652: Standard on the Fundamentals of Combustible Dust (2016 edition).
Whether dust collectors are used in your plant to ensure good indoor air quality (IAQ) for workers, keep equipment clean and/or recover high-value process dusts, you might want to consider recirculating the air back into the plant downstream of the collector(s).
A new Farr Gold Series® Package (GSP) dust collector provides high performance capture of dust and fumes generated by CNC laser and plasma cutters. Three compact but powerful models are offered to handle air flows from 1,000 to 3,000 cfm at 8-in. wg.
Camfil Air Pollution Control has introduced the Stinger™, an explosion isolation valve that isolates dust collector explosions to prevent a deflagration from traveling back through the inlet pipe of the dust collector into the workspace.
