Haver & Boecker Sieves (incl. Air Jet Replacement Sieves)

 

  • Standard Sieve Range

The Haver & Boecker test sieves with frames made from stainless steel are equipped with woven wire cloth or robust plates with square perforations according to DIN ISO 3310.

If you emphasize closer tolerances our “Gold” Test Sieves are perfect.

Test sieves with electro-formed sheets are mainly used for finest materials with particle sizes from 5 micron.

Conforming to international standards   – Fabricated according to valid standards: ISO 565, DIN ISO 3310, ASTM E 11, BS 410, AFNOR, NEN 2560, ISO 5223 etc.

 

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. 
  • Compatibility with equivalent test sieves manufactured in accordance with current standards.

 

Technical Data

We provide sieve media of electroformed sheets with aperture sizes from 5 micron up to 500 micron, sieve media of woven wire cloth with aperture sizes from 20 micron up to 125 mm and perforated plates made from galvanized steel with openings from 4 mm up to 125 mm.
