The high-performance Vitamix 5200 C-Series Blender allows you to prepare healthy smoothies, soups and other foods quickly and without a single attachment. The feedback-type variable speed control provides consistent power regardless of load; plus the C-Series features a speed range of 11 to 240 miles per hour, significantly greater than a standard blender. In short, this blender gives you all the horsepower you need. Powerful Blades The Vitamix C-Series uses aircraft-grade, hardened stainless steel blades. Every facet of the blade design process is thought through for optimal efficiency – giving the C-Series the power to blast through nuts, seeds peels and other tough ingredients to deliver up to three times the nutrition. A High-Performance Motor Vitamix blenders are built to maintain even torque and cool motor temperature, improving the consistency of the blend and the overall efficiency of the appliance. They also use a metal, rather than plastic, drive system to connect the container to the motor base. This also improves the blend, plus it lengthens the lifespan of the blender. A Different Class of Carafe Not only is the carafe engineered to create a controlled vortex that drives food into the stainless-steel blades, but it is also sized to fit your lifestyle. 64 ounces is the right capacity for preparing family-sized batches of soup, veggie dip for you next party, or fruit smoothies for you and your workout buddy.
