The AirSizer is ideal for sieving difficult and very fine dry particles from 20 æm upward. It is easy touse, extremely efficient and provides accurate reproducible results.

The AirSizer is supplied complete with its own separate vacuum source which connects to the back of the sizer. Electrical power for the vacuum unit is supplied by a connector on the Airsizer enabling a single on/off switch to supply power to both units. A safety microswitch on the Airsizer ensures that the unit can not operate unless a sieve is in place on the sieve mount plate.

Most sieving operations on the Airsizer take only a matter of minutes. Useful functions including the ability to regulate the level of vacuum, and constant or timed operation help to achieve optimum performance.

Operation:

An Endecotts Airjet sieve of the appropriate aperture size is placed in the airtight mounting plate bracket and a sealed 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.Undersize sample is discharged into the vacuum unit.
