AFC 131

AFC 131 Test System for characterisation of cleanable filter media acc. VDI 3926-2

Testing of filter media is important for the development and optimisation of filter materials as well as for quality assurance during the production process.
Filter Media Test System AFC 131 front view
Most interesting parameters for filter media characterisation are:

- differential pressure drop
- gravimetric separation efficiency
- particle size dependent filtration efficiency
- dust loading capacity

For these tasks Topas developed the AFC 131 Filter Media Test System 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. Separation efficiency and dust loading tests on basis of the general requirements of ISO 16890, EN 779, DIN 71460-1, ISO/TS 11155-1 and ISO 5011 can be performed in small scale.Due to its compact and lightweight design this test rig can be used in the laboratory.
