VB-E The double-conical flange VB-E vibrators have been desig-
ned for use in industrial processes in environments with a
potentially explosive atmosphere, caused by gas and dusts,
in compliance with ATEX Directive (94/9/EC).
They are supplied without eccentric weights, which must be
realised and mounted by the Manufacturer of the vibrating
machine. In particular, these vibrators can be used in areas
1 and 2 (gas) and in areas 21 and 22 (dusts) according to the
layout and following features:

Category: II 2 GD

Level of protection: Ex e IIC T3/T4 Gb,
Ex tb IIIC T...°C Db

Temperature class: See table

EC certificate: LCIE 06 ATEX 6092 X
