The choice of disposer size is determined based upon type and the volume of food waste or number of persons per meal.
A higher motor power and larger grinding unit allows for, besides increased grinding power, also increased pumping and transport capacity of the grounded food waste through the water trap and into draining pipe. A larger model should be chosen if the disposer is expected to run for long periods without stopping, e.g. for continuous operation during 1-2 hours when removing food waste from plates.
Similarly, when there is a borderline case between two models, the larger and more powerful model should always be chosen.
A range of mounting assemblies make it easy to install the basic models into sinks, washing lines, working benches or as free-standing units. Fittings for both continuous and batch feeding are available.
