Maşină de sitat cu jet de aer AS 200 jet
The Air Jet Sieving Machine AS 200 jet is particularly suitable for low density and low particle size materials which tend to agglomerate. It is used with sieves of 10 microns mesh size and up. The procedure is very gentle on the material as no mechanical sieving aids are required. The average sieving time is only 2-3 minutes.
The AS 200 jet is specifically designed for test sieves with a diameter of 203 mm/8“ (or 200 mm with adapter). The air jet generated by an industrial vacuum cleaner can be adjusted by using the manual vacuum regulation. Optionally, an automatic vacuum regulation is available. The Open Mesh Function, a procedure which greatly reduces the number of near-mesh particles, provides optimum separation efficiency, excellent reproducibility and a longer service life of the sieves. Sieving time and nozzle speed are conveniently selected with a single button; the settings are shown in the graphic display. The Quick Start Mode is used to start the sieving process under standard conditions without entering parameters.
RETSCH sieve shakers can be equipped with a variety of accessories to meet a wide range of application requirements.
Cyclone with holder and collecting receptable
To extend the service life of the filters in the vacuum cleaner and for recovery of the sample fraction passing the sieve, we recommend the use of the optional cyclone. The separation degree and limiting particle size respectively depend on the sample characteristics.
Test sieves 10 μm and up
RETSCH test sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the fabric of each test sieve is precisely joined into the frame and tautened.
Divizoare
RETSCH's Air Jet Sieve AS 200 jet is ideally suited for separation, fractioning and particle size determination of pharmaceutical materials, ceramics, chemical products, cosmetics, food, minerals, pigments, plastics, powder coating, rubber, toner particles and washing powder.

EasySieve, the software for particle size analyses, exceeds manual evaluation in many aspects. The software is able to automatically control the necessary measurement and weighing procedures – from the registration of the weight of the sieve up to the evaluation of the data. It is simple and convenient to use and is also available in an FDA 21 CFR Part 11-conform version.
Modelul AS 200 Jet este prevăzut cu o duză crestată rotativă. Sita și capacul sunt plasate deasupra duzei. Un dispozitiv de aspirare generează un jet de aer care dispersează particulele pe sită prin duza crestată. Materialul care este mai mic decât dimensiunea ochiurilor sitei este transportat de curentul de aer din spate spre ciclon sau aspirator. Jetul de aer ajută la dezaglomerarea particulelor și curăță permanent ochiurile sitei.
