New Air Jet Sieve From Retsch

RETSCH’s new air jet sieve AS 200 jet is particularly suitable for low density materials with particle sizes in the lower micron range. It is used with 200 mm and 203 mm (8’’) sieves of 10 microns mesh size or more.

An industrial vacuum cleaner generates a jet of air which disperses the particles on the sieve through a slotted nozzle. The material which passes the sieve is transported to the vacuum cleaner or to a cyclone for recovery. The procedure is very gentle on the material; the average sieving time only takes 2-3 minutes. A special feature of the AS 200 jet is the Open Mesh Function which helps to greatly reduce the number of near-mesh particles. This provides optimum separation efficiency and also excellent reproducibility. Operation of the sieving machine is very simple and user-friendly. The Quick Start Mode allows starting the sieving process without previous programming.

Benefits at a glance:

  • Gentle sieving with short sieving times
  • Reproducible results due to Open Mesh Function
  • High flexibility through adjustable nozzle speed
  • Automatic vacuum regulation (option)
  • Suitable for 200/203 mm (8 ‘’) test sieves
  • Memory for up to 9 SOPs, additional Quick Start mode
  • Silent operation due to integrated silencer
