Or do you mean the AT641? It grates the vegetables/fruits and squeezes them. The SlowJuicer crushes everything and then squeezes it. It's just the newer version. According to Kennwood, the yield is better with the SlowJuicer. I have the SlowJuicer and am satisfied.

I don't know the Pure Juice, but this is about two juicers that you can connect to the big Kenwood machine, isn't it? If you want juice quickly, then you have to buy the juicer. The juicer is a centrifuge, which means that something spins very fast and separates the juice of the grated fruit from the rest by spinning. There is speed in it and it is not quite as cold and gentle as the Lansamsafter (slow juicer). The slowjuicer is healthier but slower. We make super healthy and really high-quality juices with the slowjuicer.

So if you mean the Pure Juice, I would say mechanically there is no difference. One is a stand alone device and the Slow Juicer is an attachment for the Kenwood kitchen machine. But juice always comes out of the end ;o)
