Product Description
Description
The MVB-FLC series is made up of vertical vibrators with central flange and shaft projecting on both sides. These vibrators are typically used in circular screens and medium-size and large sieves, and can be supplied in 4 different versions, depending on type of eccentric weights supplied to be assembled by the user. Frame size 50 is only available in B, C and D versions. The size 50 complies with the most recent IEC and EN international standards for use in atmospheres with potentially explosive powders. In particular, the size 50 series can be used in areas 21 and 22.
