Flameless Explosion Vents are a safe and effective solution for protecting machinery and personnel located indoors. The EV-VQ provides effective low-pressure resistance and eliminates the spread of flame and glowing particles. During the beginning stage of a deflagration the interior explosion panel opens and dust (burning and non-burning) enter the flame arrestor. Flame propagation beyond the EV-VQ is prevented by energy dissipation in the arrestor, reducing the burning fuel below its ignition temperature. All dust is retained within the EV-VQ and gases from the explosion are vented through the device into atmosphere.
