S-Max The screenless granulators in this Wittmann series are designed to process tough materials. Standard features include a mechanical rotary high-level sensor with a light hopper-mounted magnet; anti-vibration pads; motor overload protection; stainless steel material bin with casters; an insulated, double-walled infeed hopper for noise reduction; PC viewing window; and lift assist hopper for ease of cleaning. 

What’s new? The S-Max Dual 8, featuring new motor orientation and gearbox, which are upgrades over the model it replaces, the Junior Double 8. The Junior Double 8 had horizontally positioned motors, while the S-Max Dual 8 has vertically positioned motors, resulting in a smaller footprint.
