Evolution excel 1hp disposer | delivering powerful, ultra-quiet performance, the insinkerator evolution excel 1 hp continuous feed garbage disposal features advanced technologies that effectively grind even the toughest food waste and make far less noise while doing it. The evolution excel garbage disposer features a heavy-duty 1 hp dura-drive induction motor for quiet operation and long life. Soundseal technology delivers ultra-quiet performance, making it possible to have a normal conversation by the sink while your kitchen garbage disposal is working. It uses anti-vibration technology, sound-reducing insulation, and a special quiet collar sink baffle to block noise from coming up through the sink opening. Soundseal plus reduces disposer noise by at least 60 percent compared to standard disposers, while handling more volume and more types of food waste. Multigrind technology provides 3 stages of grind rather than 1 stage like standard disposers, reducing food scraps into even smaller particles. An auto-reverse grind system feature automatically reverses grind direction, ensuring grind elements wear evenly for longer disposer life. With a 1725 rpm motor and continuous feed, the powerful evolution excel garbage disposal handles large amounts of tough waste like corn husks, bones and melon rinds, and a jam-sensor circuit automatically increases torque to break through tough jams. A large 40-ounce capacity grind chamber allows you to dispose of food waste right into the sink, keeping the food preparation area clean and reducing the amount of bagged garbage. Built rugged, the stainless steel grind chamber and components provide superior durability and protect against corrosion. This insinkerator garbage disposal has a patented quick lock mounting system for easy installation and replacement of garbage disposers. The quick lock mount is completely compatible with all insinkerator models. When it's time to upgrade or replace, simply twist off the old mount and twist on the new one.
