NetterVibration, leading manufacturer of pneumatic, electric and hydraulic vibrators, will in future supply series NEG electric external vibrators certified for potentially explosive dust atmospheres (ATEX zone 21 and 22), at no extra cost. This means an expansion of the possible applications for the standard version. The change will be implemented successively, up to the end of 2007.
In addition, the special series NEG E version (ATEX) for explosive gas and dust atmospheres (zone 1, 2, 21, 22) will continue to be available.
Electric external vibrators are unbalance motors, which work according to the short-circuit runner principle and, apart from a few significant differences, are very similar to conventional electric motors. They serve as drives for conveyor troughs and sieves. They can also be used to relieve product congestion and loosen adhesions in silos.
