With the exception of DV30 (horizontal  air outlet), all other types have vertical outlet. Lasting value and  long life are guaranteed through the use of reliable external rotor   motors and high quality materials. 
 Wolf also leaves nothing  to be desired when it comes to accessories. These range from a variety  of different plinths, silencers for special acoustic conditions and  accessories for duct connection, to a comprehensive range of switching  and control devices.
