If your dust collector handles combustible dust, the National Fire Protection Association (NFPA) requires you to equip your system with deflagration protection. That's why Camfil APC offers the Stinger™ explosion isolation valve, a cost-effective, NFPA-compliant way to contain a deflagration that occurs in a dust collector.
The flow-activated valve prevents an explosion, smoke, dust and burning debris from traveling back through the dust collector’s inlet pipe and into the workspace. It is thoroughly explosion tested and is designed and tested to meet NFPA & EN 1779 standards for a range of applications and dust types.
