This SS-300-25 food disposer is designed for a full-service restaurant operation and is excellent in grinding heavy food particles (meats and seafood). It will also last for a long time. Why? Because it is made from a corrosion-resistant stainless steel both on the outside as well as its grinding chamber. Also, the double-tapered Timken roller bearing shock-absorbing device prevents unnecessary water hammering in the connection from the sink to the disposer. This food service garbage disposal is integrated with a triple lip seal. What does this seal do? It actually saves your garbage disposer from water damage, at the same time, helps you save money and effort in buying a new one, or maintaining your old one. Indeed, it is the kind of disposer that you can trust for your everyday kitchen operations. Having complied with ISO standards, this unit is safe to use. It is also backed by Insinkerator's 1-year warranty.
