Comparison In-Sink-Erator Model 66 vs In-Sink-Erator Model 56

This refers to the electric motor power of the waste disposal unit, which determines its efficiency and ability to handle large volumes of waste and solid particles. Higher power means faster processing, but it also leads to increased energy consumption and cost. Therefore, it is important to consider specific usage conditions when selecting a grinder based on its power. So, for small volumes and relatively soft waste, engines up to 0.5 hp are enough, and for more serious tasks, more powerful units are already desirable.

The power consumption and the power of the motor are related, and the formula to convert between them is 1 hp = 735 W. The power ratio is important in determining the energy efficiency of the waste disposal unit, and a larger difference between these values indicates lower efficiency and greater energy waste. However, some manufacturers may provide the peak power of the engine instead of the nominal power, which is not a reliable indicator of efficiency since the waste disposal unit can only operate in this mode for a short period. It is important to consider these factors when choosing a device based on power consumption and efficiency.

The motor shaft's nominal speed is a crucial factor in the operation of the waste disposal unit, as it determines the speed of processing. Models with higher nominal speeds can process waste faster than those with lower speeds, provided that their power and other features are equal. However, high speed can also lead to increased noise levels and a reduced ability to handle solid particles.

Waste disposal units often include an auto-reverse function, which automatically changes the direction of the working tool's rotation. This periodic change is believed to enhance processing quality, accelerate the process, and prevent jamming of the device.
