Blast & Fire Protection Systems

Flameless Venting Device

Release explosion pressure safely while keeping flames and hot gases from escaping into the surrounding area.

Flameless Venting Device

How it works

A flameless venting device is fitted over a vent opening. When an explosion starts, the expanding gases pass through a stainless steel element that cools them and extinguishes the flame, so the pressure is released without a fireball. This allows venting where a conventional vent cannot discharge outdoors.

Typical applications

  • Dust collectors and silos inside buildings
  • Equipment next to walkways, workstations or other plant
  • Process areas where a vent duct to the outside is impractical

Standards and guidance commonly referenced for this product type

  • EN 16009
  • EN 14491
  • NFPA 68
  • ATEX 2014/34/EU

These are general references. Compliance and test reports for a specific product are provided per project.

When is flameless venting used instead of a vent panel?

Flameless venting is used when the vent cannot discharge to a safe outdoor area, for example for equipment inside a building. The device must be selected for the specific material and sized for the enclosure, because it changes the pressure that builds up during the explosion. It does not replace a correct explosion risk assessment.
