MVSS
The MVSS stainless steel series vibrators are characterized
by their total protection from liquids, dusts, aggressive
agents and contaminants, thanks to the AISI 304 stainless
steel casing and external components.
Line MVSS-P is available for potentially explosive dust at-
mospheres in conformity with ATEX Directive 94/9/EC.
