SIEVING MACHINE MODEL:
Air Sizer 200
General Information
The Air Sizer 200 has an air nozzle, which is set rotating. The sieve with a Plexiglas lid is put on top of that. A
vacuum unit generates a jet of air, which disperses the particles through the air nozzle on the sieve.
The material, which is smaller than the mesh size of the air jet sieve, is transported by the backflow of the air
into the filter unit or directly into the vacuum cleaner. The jet of air de-agglomerates the particles and cleans the
sieve mesh constantly.
The Air Sizer 200 is specially designed for the dry sieving and the particle size determination of fine-grained,
dry, pourable and dispersed bulk materials. The sieve holder is suitable for 8“(203 mm) diameter test sieves
(premium air jet sieves)
Advantages
xCompact and portable (weighing only 14 kg)
xRequires only small storage space due to small footprint
xThe device is essentially maintenance free if cleaned regularly
xEasy to use
xIdeal for electrostatic materials
xWide range voltage supply
xCan reduce the average sieving times in samples with a high fine fraction
