The Dynapro High-Power Professional-Grade Vacuum Blender features a powerful 2.5 HP motor, integrated 4-spoke blending blade, a large 64 oz. container, and a vacuum blend option. The Dynapro Blender Vacuum Lid is designed to work with the included handheld Vacuum Pump, to reduce oxidation by removing air before blending. With less oxidation, you can enjoy more nutrients and enhanced flavors in your smoothies, juices, sauces, and more. The Dynapro blending container includes a unique thermochromatic ink raw temperature star indicator that changes color from blue to white at 118 DegreeF or above so you can either maintain a raw temperature in your blend for maximum nutrient retention, or know when you reach cooking temperature for soups. The Dynapro offers unparalleled convenience with 3 modes of operation: manual, countdown timer, and 3 one-touch preset buttons, as well as a variable speed dial for total control over your blend.
