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. Following extensive testing, Camfil APC reports that the Stinger is the first U.S.-made explosion flap valve to be certified by an independent testing agency to comply with NFPA standards. It may be retrofitted onto most dust collection systems and used with new or existing Farr Gold Series® dust collectors where the risk of a combustible dust explosion exists.
