Air Jet Sieve in 304 Stainless Steel (AISI 304 (1.4301)) 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. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Air Jet Sieve Is Used
- Cement & building materials: fineness testing to EN 196-6 and ASTM methods.
- Pharmaceutical QC: particle-size checks on APIs and excipients.
- Food powders: flour, starch and milk powder fineness.
- Pigments & toners: oversize checks on fine powders.
Ordering Air Jet Sieve in 304 Stainless Steel
- 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.
Mistakes to Avoid with Air Jet Sieve
- Using a standard test sieve frame that does not seal on the air-jet machine.
- Overloading the sieve with sample.
