This powerful blender generates a vacuum in the jar so that less oxygen enters the contents. The oxidation process is minimised, and smoothies retain their colour and vitamins for longer. When blending, powerful “ProBlend 6 3D” technology is applied which is visually reflected in a blade set designed with coloured spacers as well as concise ribs in the glass jar. Operation via the centrally located rotary knob with light ring is self-explanatory.
