The MVB-E and MVB-E-FLC flanged vibrator series have been designed for use in industrial processes with screens and sieves in environments with a potentially explosive atmosphere, caused by gas and dusts, in compliance with ATEX Directive (94/9/CE). These vibrators can be supplied in B, C, D versions (see page 86) according to the eccentric weights supplied with the vibrator and to be mounted by the user. In particular, these vibrators can be used in areas 1 and 2 (gas) and in areas 21 and 22 (dusts).
