Four-liter blenders have two handles to ease lifting, pouring, and carrying. All models process liquids at 15,800, 18,000, or 20,800 rpm and pulse. Model 04240-08 has a three-minute timer for unsupervised blending. The easy to clean membrane control panel features five settings: Off, Low, Medium, High, and Pulse. The 3.75-hp motor is encased in the base for quieter operation. Nonskid rubber feet keep the unit stable.
