Laboratory analyses for the dedusting technology

We will be pleased to carry out extensive analyses for you as part of a filter test. The tests take place systematically under controlled conditions in our state-of-the-art laboratory.

The performance spectrum of our professional analyses:

Filter bags tests (new and used filter bags):

  • Measurement of physical data
  • Manufacturing specification
  • Determination of quality, structure and equipment of the material
  • Microscopic surface and cross-sectional images
  • FTIR spectroscopy
  • Shrink tests

Dust analyses:

  • Filtration test according to ISO 11057 (VDI 3926)
  • Analysis of the particle sizes
  • Determination of the bulk density
  • pH-tests
  • Annealing loss determination

At the end of our laboratory examination, the results will be documented in a laboratory report. We will be pleased to assist you and show you not only individual weak points, but also potential savings.
