Air jet sieving system for powdered materials
Optimize particle distribution with precision air jet sieving, designed to enhance the accuracy of fine powder separation and maximize efficiency when tackling challenging deagglomeration tasks in your batch processing operations.

Disperses and Sieves Fine Powder Particles
The AS 200 jet from Retsch is an advanced air jet sieving machine specifically designed for the precise separation and dispersion of fine powder particles. Utilizing a unique rotating slotted nozzle mechanism, it ensures efficient deagglomeration and consistent particle distribution, vital for applications ranging from pharmaceuticals to chemical products. The equipment is ideal for industries producing cosmetics, minerals, ceramics, and plastics, processing materials such as lipstick ingredients, iron ore powders, and polyethylene pellets. The machine allows for batch operations with digital controls that manage particle size determination accurately within a range of 10 µm to approximately 4 mm. Equipped with options for manual or automatic pressure regulation—leveraging a powerful industrial vacuum for operation—it reduces operational noise and ensures ergonomic ease. It is compatible with standard 203 mm or adapted 200 mm sieves, maintaining compliance with ISO 9001 standards for measurement. Maintenance is simplified through its robust, maintenance-free design, while optional accessories such as cyclone systems enhance its utility. This machine supports up to nine SOPs, offering flexibility in processing setup, making it an indispensable tool for laboratories and processing departments focused on quality control and material analysis.
