Air Sizer 200 Sieving Machine

Ideal for sieving very fine dry particles, which require efficient dispersion and desagglomeration via air jet technology (e.g. electrostatic material).

It is also the perfect instrument to quickly provide a sieve cut of powdered materials.

An Endecotts sieve of the appropriate aperture size is placed in the airtight mounting plate bracket and a lid is placed on top of the sieve.

Vacuum is applied to the chamber beneath the sieve drawing air out of the sieve through the apertures and carrying with it any undersize particles. To create a continuous flow, positive pressure air is drawn into the sieve through a channel in a rotating arm placed immediately below the microplate or sieve mesh. The incoming air creates a wave within the sample helping
to fluidise the sample and clear any blocked apertures. Any undersize sample is discharged into the vacuum unit.
