12.1 Automatic Vacuum Regulation
As an accessory available from Retsch GmbH, the automatic vacuum regulation allows for the
automatic control of the airflow strength on the Air Jet Sieving Machine AS 200 jet in the control
range
Δp of 20 mbar.
The AS 200 jet measures the current negative pressure in the nozzle chamber (
A ) and
accordingly controls the automatic vacuum regulation. As a result, fluctuations caused by the
industrial vacuum cleaner are compensated and thus the negative pressure kept stable.
