AFC 130/131 – Filter Media – VDI 3926-2

AFC 130/131 – Filter Media – VDI 3926-2

Testing of filter media …

is important for the development and optimization of filter materials as well as for quality assurance during the production process. Of most interest for filter media characterization are:

– differential pressure drop,
– gravimetric separation efficiency, 
– particle size dependent filtration efficiency
– and dust loading capacity. 

For these tasks Topas developed the Filter Media Test System AFC 130/131 which facilitates filter tests in accordance with guideline VDI 3926 exemplary embodiment 2 and ASTM D6830-02, but can also be used for other tests. Dust loading tests and dust capacity tests on basis of the general requirements of EN 779, DIN 71460-1 and ISO/TS 11 155-1 can be performed in small scale.   
Due to its compact and lightweight design this test rig can be used in the laboratory. Only single-phase mains power and compressed air are needed to run filter tests.  The Windows based Topas control and data acquisition software PAFWin runs on standard PCs. 

Advantages:

  • Following test procedures and test standards are supported by the control and data acquisition software PAFWin
  • Differential pressure test
  • Dust loading capacity
  • VDI 3926
  • DIN 71460-1
  • ISO 11 155-1


Applications:

  • Determination of fractional separation efficiency, dust loading capacity and differential pressure drop of filter media
  • Filter tests for cleanable filter acc. to VDI 3926-II
  • Filter tests based on other standards
  • air cleaning filters EN 779
  • cabin air filters ISO 11155-I
  • Development and optimization of filter media
  • Quality assurance measurements
