Flameless venting device

Flameless explosion relief



For the device security with the flameless dust explosion relief, VST Engineering uses its own protection system ANTIDET FQ Relief.


What is ANTIDET Relief FQ used for?

The protection system ANTIDET Relief FQ is used for releasing the explosion pressure and other explosion pollution to the vicinity of the protected device, and unlike in other common elements for the relief, the flame does not penetrate the vicinity of the protected device. However, it still represents a passive element, which does not intervene in the combustion process during explosion.

Just like all systems for the explosion relief, it requires the delimiting of sufficient security zone for the explosion products relief, where persons, obstacles, and environment with explosion hazard cannot be present. It further requires the combination with the system for the explosion separation.


What are the system components?

ANTIDET FQ Relief is a series of circular and rectangular bursting membranes in stainless design with a basket for the flame arresting. Each relief element is equipped with the opening signalling as a standard.


What is the system function?

The explosion occurrence is accompanied with the pressure growth. Each relief element includes a defined pressure value during which it opens (bursts). This opens a way for the explosion products release outside the device into the safe zone except for the flame, which is arrested by the basket above the membrane.
