Air Jet Sieving Machine AS 200 jet

The new Air Jet Sieve AS 200 jet is particularly suitable for sieve cuts of powdered materials which require efficient dispersion and desagglomeration. The option to store up to 10 SOPs and the automatic vacuum regulator (accessory) guarantees reproducible and meaningful results. Innovative features such as the Open Mesh function, the selection of the nozzle speed as well as optional use of standard 2" high test sieves perfects the new air jet technology.


  • sieving with air jet technology for dispersion and desagglomeration of fine powders
  • Open Mesh Function to reduce the number of near-mesh particles
  • high flexibility through adjustable nozzle speed
  • operation with standard Retsch sieves, 203 mm (8")Ø or 200 mm Ø (with adapter), 1" or 2" high
  • free manual (standard) or automatic (accessory) pressure regulation
  • optional software EasySieve for control through RS232 serial interface, easy evaluation and documentation of results
  • free digital adjustment of all process parameters (time, vacuum, speed)
  • additional Quick Start mode
  • silent operation due to integrated silencer
  • collection of two fractions possible by use of cyclone
  • air jet produced by a powerful industrial vacuum cleaner
  • fulfils all criteria for measuring equipment related to ISO 9001
  • easy operation, ergonomic design
  • maintenance-free
  • memory for up to 9 SOPs
