The MVTX explosion-proof screen vibrators have been designed for use in industrial processes in a potentially explosive atmosphere. They are used for industrial processes on screens. The enclosure of these screen vibrators is equipped with increased thickness and joints to prevent the transmission of an internal explosion to the surrounding area. Explosion-proof screen vibrators bear the UL, cUL, ATEX and IECEx markings
