Every KitchenAid® disposer is equipped with a motor that rotates at 1725 RPM for effective grinding. In addition, it features overload protection with a manual reset, a batch feed allowing effective handling of large quantities. The design adds a measure of safety since it comports a cover that must be locked in place before the disposer operates. The MultiGrind Plus Technology features a three-stage grinding that makes this disposer an ideal solution for stringy foods such as corn husks and celery. A sensor helps break through tough jams before a problem occurs. Its SoundSeal Plus Technology makes these disposers exceptionally quiet even when grinding hard or stringy foods. The technology helps reduce noise levels by up to 60% compared to other standard disposers. This product is backed by a 30-day warranty.
