Air Jet Sieve is used for measuring the fine fraction of powders below 100 µm on air jet sieving machines, where a rotating slit nozzle blows the powder off the sieve while a vacuum pulls the fines through. DIN 66165 is the reference cited for it on drawings, datasheets and purchase orders.
What DIN 66165 Means for Air Jet Sieve
The dimensions in the table below are supplied to suit DIN 66165. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
Air Jet Sieve Dimensions
| Aperture (mm) | Frame diameter (mm) | Frame height (mm) | Wire diameter (mm) | Mesh count | Frame |
|---|---|---|---|---|---|
| 0.020 | 200 | 25 | 0.020 | 635-Mesh | SS304, air-jet seal |
| 0.045 | 200 | 25 | 0.032 | 325-Mesh | SS304, air-jet seal |
| 0.063 | 200 | 25 | 0.045 | 230-Mesh | SS304, air-jet seal |
| 0.090 | 200 | 25 | 0.063 | 170-Mesh | SS304, air-jet seal |
Specifying Air Jet Sieve Beyond the Standard
- Aperture: 20–90 µm cloth to ISO 3310-1.
- Frame: 200 mm frame with the air-jet sealing face that fits the machine.
- Certificate: Inspection or calibration certificate for audited labs.
When Air Jet Sieve Is Not the Right Choice
Not for coarse samples above about 200 µm, where shaker sieving is quicker.
