Efficient air management and a sound enclosure made of Eastman Tritan™ polymer help to dampen the sound for a truly quiet blender. This makes it perfect for use behind the bar and in other front-of-house areas, as it won't create loud grating and grinding noises that interrupt customer conversation. It instead operates with a gentle whirring noise to create a comfortable dining environment. Plus, the twist-lock sound enclosure is easy to remove and clean and features a large centering pad to catch spills. A 120V electrical connection is required.
