The new air jet sieve AS 200 jet is particularly suitable for the separation of fine powders that require mixing and effective disintegration.

The ability to store up to 10 SOPs and the automatic vacuum regulator (accessory) guarantee reproducible results speak for themselves. Innovative features such as the "Open Mesh" function, the nozzle variable speed and the optional use of screen frame 50 mm high perfecting the new air jet sieving technology.

Function Principle

The AS 200 jet is equipped with a slot nozzle which describes a rotational movement and over which is placed the sieve with its lid. A vacuum cleaner generates an air flow through the slit nozzle and then vortexed particles on the sieve. The particle size smaller than the sieve mesh opening are transported to the cyclone through the air reflux or they are picked up by the vacuum cleaner. The air flow ensures the deagglomeration of the particles and continuous cleaning of the sieve mesh.
