The A.S.which comes supplied with a separate vacuum unit, provides an ideal and economic solution for the sieving of very fine dry materials from 5um upward.
The A. S. is supplied with additional rear mounted electrical outlet and suction pipe sockets for easy connection of the vacuum extraction unit which collects the undersized (passed) sieved samples for analysis if required.
Recommended for electrostatic materials
Principle of Operation
A measured quantity of the sample to be screened is placed on the selected sieve and the polycarbonate lid is then placed on top. The powerful vacuum unit generates a negative pressure in the bowl below the sieve, which induces an airflow dislodging the sample above the sieve surface by means of a rotating nozzle located below the sieve creating a “blade” of air. The same airflow simultaneously draws the undersize air borne particles from the sample back through the sieve apertures. The undersize particles are deposited as defined above for the A.S. Does not require special air jet sieves.
