This is where the air jet sieve e200 LS develops maximum effectiveness. Not just one, but two components work together here: a slotted nozzle which rotates inside the sieving chamber and an industrial vacuum cleaner connected up to the sieving chamber. Once the vacuum cleaner is switched on, it creates a vacuum inside the sieving chamber.
