1. Permanent Magnet or Induction Motor
The Permanent Magnet motor starts at full speed with it first revolution breaking through the waste instantly. The Induction motor builds up gradually to reach its full speed and will therefore be quieter.
2. Motor Size
Motors start at 1/2 horse power and go up to 1.25 horse power, the more people in your household the more it will get used so we suggest that you select a horse power to suit your needs.
3. Physical Dimensions
It is important to check the size to make sure it will fit in the space available. Avoid having a shelf immediately below it as some machines have their reset/overload buttons on the base.
4. Batch Feed or Continuous Feed
Continuous feed disposers are very convenient. Once the machine is switched on and the water is running the food is fed into it continuously until it has all been disposed of.
There are three methods to switch it on:
- on/off wall switch spurred off from the 13amp supply under the sink
- air switch is set into the worktop. This sends a pulse of air to the machine to switch it on & off. Very safe with damp hands.
- Remote Control Unit
Batch feed units are very safe and ideal if there are small children around as the machine can only operate when the special stopper in place. It disposes of the food in batches.
Operational Noise -
The disposers with induction motors are generally quieter than the machines with permanent magnet motors. However, the p.m. machines run much faster (2600rpm) and usually grind food waste very finely. They are a must if your pipework is long/bendy/complicated.
