Efficiency measurement

In order to adequately characterise filter media, a large number of parameters is tested:

  • Differential pressure behaviour
  • Gravimetric separation efficiency
  • Fractional collection efficiency
  • Dust loading capacity

In this area, our technologies test filter media in accordance with the standards ISO 16890, ISO 29463, ISO 5011, VDI 3926, ISO 11057, DIN 71460-1 and ISO/TS 11155-1.

Good to know

For customers who already own other filter testing systems from our company:

Filter media can also be tested with nearly every filter testing system (PAF 11x, ALF 114, AFS 150, ABP 115, SPT 140). For filter media evaluation, the
AFS 153  media tester can be integrated into your existing filter testing system as a retrofit set. This is a good investment for, e.g. incoming goods inspections. Contact us if you have any questions.
