One of the most economic and efficient methods of sizing particles in the micron range

The Air Jet Sizer is ideal for sieving difficult and very fine dry particles from 20 æm upward. It is easy to use, extremely efficient and provides accurate reproducible results.

• Extremely efficient
• Fast sieving times
• Suitable for dry material of 20 µm upward
• Sieving action keeps apertures clear
• Air flow fluidises and helps to separate sample
• Ideal for electrostatic materials
• Variable vacuum control
• Safety micro-switch

The Air Jet Sizer can be supplied 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 Air Jet Sizer enabling a single on/off switch to supply power to both units. A safety microswitch on the Air Jet Sizer ensures that the unit cannot operate unless a sieve is in place on the sieve mount plate.

Most sieving operations on the Air Jet Sizer 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 Air Jet 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 micro - plate 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.
