QUICK QUOTE OPERATING INSTRUCTIONS

The AIR SIZER is a precision analytical  instrument designed for the separation of very fine particles, including materials that exhibit electrostatic properties.The A. S. is supplied with additional rear mounted electrical outlet and suction pipe sockets for easy connection of a vacuum extraction unit which collects the undersized (passed) sieved samples.

Because HEPA Filters are generally used to prevent fines from being introduced in to the environment, vacuum sievers are not recommended for applications requiring non destructive separation of fines. 

 Advantages

 Advanced air jet technology for fine particles, usable   for dry material 20 µm upwards

 Adjustable nozzle speed, 5 - 55 rpm  Extremely efficient & fast sieving times  Sieving action keeps apertures clear  Air flow fluidises and helps to separate sample  Ideal for electrostatic materials  Pre-filter unit & industrial vacuum available as accessories  Maintenance-free

Air Jet Siever # 600 AS200 (REQUIRES 200 mm sieves) HOW IT WORKS

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 microplate or sieve mesh.

The incoming air creates a wave within the sample helping to fluidize the sample and clear any blocked apertures.Undersize sample is discharged into the vacuum unit.

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

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 can not 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.

Extensive Control Anti-Vibration Feet Unique Clamping

Endecotts shakers are fitted with a unique clamping device, enabling the clamp plate to be fitted in seconds. It also ensures the clamp plate secures the sieves with consistent pressure to provide consistent results and longer sieve life. Anti-Vibration Feet maintain optimum performance and avoid shaker ‘walking’. Most Endecotts shakers are fitted with a high degree of control over all shaker functions - a feature extremely useful for many materials and in many industries.
