An explosion vent is a pre-scored metal membrane engineered to rupture when pressure hits a specific point, offering a controlled release path for combustion hazards during an explosion. By rapidly reducing pressure during a dust explosion, vents help to minimize damage to your containment vessel and the surrounding areas.

Explosion vents offer cost-effective protection against overpressure events, especially in ductwork or other non-contained spaces where explosion doors cannot be used.

However, unlike explosion doors, vents need to be replaced once burst. Also, unlike doors, vents cannot be recalibrated in place and will need to be replaced if your process or pressure requirements change. 

Vent membranes also tend to suffer fatigue over time and need to be replaced periodically to ensure adequate protection.
