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
- 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.
