Test Sieves for ALPINE Air Jet Sieves

ALPINE Test Sieves with openings from 20 micron

Alpine Test Sieve 200 LS-N

If you know the Air Jet Sieve by ALPINE, you also know the corresponding test sieves by HAVER & BOECKER. Finest dry bulk materials can be analysed with this machine. In addition to test sieves for the 200 LS and 200 LS-N we quote the special execution for the e 200 LS with fully automatic sieve detection.

Conforming to international standards

  • Fabricated according to valid standards:
    ASTM E11, DIN ISO 3310, BS ISO 3310

Your advantages at a glance

  • A particularly smooth surface of frames prevents cross-contamination.
  • An extremely stable sieve structure guarantees a long life.
  • The sieve fabric retains its tension exceedingly well even after intensive use.
  • Test Sieves e 200 LS: fully automatic sieve recognition due to a plastic transponder chip.

Application examples for ALPINE Test Sieves

Alpine Test Sieve 200 LS

ALPINE Air Jet Sieves are used for particle size distribution of powdery materials from 20 micron.

An air flow exiting the rotating slotted nottle purges the sieve gauze continuously. This leads to short sieving times and ensures that even those materials which are known to cause difficulty can be sieved successfully.

The Alpine Air Jet Sieve and our corresponding test sieves are used in different industries like pharmacy, chemical or food industry.
