The AS 200 jet has an air nozzle, which is set rotating. The sieve with lid is put on
top of that. A vacuum unit generates a jet of air, which disperses the particles
through the air nozzle on the sieve. The material, which is smaller than the sieve’s
mesh size is transported by the backflow of the air into the cyclone or directly into
the vacuum cleaner. The jet of air de-agglomerates the particles and cleans the
sieve mesh constantly.

The AS200jet is intended for Retsch test sieves with a diameter of 203mm (8
inches) and a height of 25mm (1 inch) or 50mm (2 inches). The range of mesh
fineness extends from 10µm to approx. 4mm.
Fig. 7: Inserting the test sieve
Place the sieve in the nozzle compartment (T).
Close the sieve with the air jet sieve lid (A) intended for the respective sieve height .
NOTE
The AS200jet cannot be started until the sieve has been inserted and the lid put
on.
