InSinkErator is launching a new PRO Series line of disposers. The line includes five models, all of which feature the Auto-Reverse Grind System ranging from 3/4 horsepower to 1.1 horsepower. Longer warranties are included, from six to 12 years. All models feature advanced MultiGrind and SoundSeal technologies, allowing users to grind nearly any food waste and hear almost nothing — from chicken and rib bones to fibrous food such as celery. The PRO Series line is the official disposer of the PHCC – National Association.
