Vigispace VS Explosion Vent Deflectors

A spark detection and extinguishing system (like our Raptor line) continuously monitors ductwork for sparks or embers generated upstream by grinding, cutting, or other hot processes, and automatically extinguishes them with a water mist before they reach a filter or collector where they could ignite accumulated dust. It's typically recommended wherever a process both generates sparks and feeds a dry dust collection system.

An explosion vent (like our Vigilex domed or flameless vent panels) is designed to relieve pressure safely to the outside of a vessel if a dust explosion occurs inside it. An explosion isolation valve (like our Vigiflap valves) is designed to stop flame and pressure from traveling through ductwork from one piece of equipment to another, preventing a secondary explosion elsewhere in the system. Most combustible-dust systems use both as part of a layered protection strategy.
