Flameless Explosion Vent Devices are safety equipment for dust explosion protection of indoor dust collectors, elevators, silos, and similar facilities.

Their working principle is as follows: The bursting disc rapidly responds to and opens under explosion pressure to release the overpressure, while the flame-arresting module (flame-retardant mesh) blocks and cools the flame, traps dust particles, and eliminates deflagration flames and hot gases. This prevents secondary explosions.

Compliant with the EN 16009-2011 standard, these devices are widely used for pressure relief and flame-arresting explosion protection in food processing plants, flour mills, feed mills, grinders, chemical plants, pharmaceutical factories, textile mills, paper mills, breweries, steel plants, rubber factories, granaries, and various containers. They come with product test reports and certificates of approval recognized by emergency management authorities.
