RETSCH Air Jet Sieving Machine, AS200 jet


The AS200 jet Air Jet Sieve is particularly suitable for sieve cuts of powdered materials which require efficient dispersion and desagglomeration


The AS200 jet Air Jet Sieve 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 in. high test sieves perfects the new air jet technology.
