Flameless vents are designed to be installed over a standard explosion vent. A flameless vent extinguishes the flame exiting the vented area, preventing it from exiting the device. With flameless venting, conventional venting can be placed indoors as long as there is a designated safe zone.
Almost all industrial manufacturing, processing or packaging applications generate dust as a side effect. Many of these dusts are both combustible as well as explosive, and removing them from the work place can significantly reduce the risk of serious accidents. It is estimated that there are approximately 2,000 dust explosions in Europe annually. Most of these are minor but some are very destructive. So by extracting the dust, the risk in the production is reduced, but unless the extraction system is safe the risk is just moved.
