Product Description


VB Series

Flanged Electric Vibrator

Electric vibrators with double tapered mounting flange


The VB series is made up of vertical vibrators with double conical flange. These vibrators are typically used in circular screens and in medium-size and large sieves. They are supplied without eccentric weights, which must be realized and mounted by the Manufacturer of the vibrating machine. The VB series complies with the most recent IEC and EN international standards for use in atmospheres with potentially explosive powders. In particular, the VB series can be used in areas 21 and 22.
