The French Stif Vigilex VQ flameless flame arrester is one of the Vigil Ex series launched by STIF company: Vigil Ex VQ flameless flame arrester.

VigilEx VQ is a flameless explosion-proof device that has passed ATEX certification (EC certificate: INERIS 14ATEX 0049X), suitable for both indoor and outdoor use.

To protect indoor equipment, VigilEx VQ ensures flameless explosion and dust protection, preventing combustion and incomplete combustion of dust leakage, and reducing temperature to a minimum. Due to the traditional method of venting, flames and dust are freely discharged into sealed containers. When the equipment is indoors, it usually transports dust to the outside. This method not only incurs high costs, but also greatly reduces the effectiveness of venting due to limitations in the selection of venting ports and ventilation ducts.

The venting port of VigilEx VQ is square shaped, and the base is equipped with a square explosion-proof plate, which transmits signals through sensors. VigilEx VQ has different sizes to choose from. This product has been certified by INERIS and complies with the new European standard: EN 16009:2011
