The Air - Jet Sizer is ideal for sieving difficult and very fine dry particles from 20 µm 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 micro switch 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.

A 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 sieve mesh.  Undersize samples are discharged into the vacuum unit

The same powerful vacuum unit generates a negative pressure in the bowl below the sieve, which induces an airflow dislodging the sample above the sieve surface by means of a rotating nozzle located below the sieve creating a “blade” of air. 

After the sieving cycle is completed the remaining sample is weighed and the percentage retained / passed through can be calculated.

Assembly

The Air – Jet Sizer should be mounted on a level bench top allowing access to the rear panel connections for the vacuum hose and electrical power cables. The vacuum unit should ideally be positioned on the floor at a distance that will enable connection of the 2 metre long flexible hose to the inlet nozzle located in the rear panel of the Air – Jet Sizer Connect the power lead of the vacuum unit to the power outlet socket also in the rear panel of the Air – Jet Sizer.
