Testing of Filter Media is important for both the development and optimization of filter materials, as well as for quality assurance during the production process. The most interesting features for the characterization of cleanable filter media are:
● Curve of pressure drop,
● Curve of residual pressure drop,
● Fractional efficiency,
● Gravimetric separation efficiency,
● Dust penetration through the filter medium,
● Loading capacity of the filter.
 Our company has developed its filter testing systems of series AFC for the determination of this standardized performance parameters. This test equipment allows testing of specific filter media for cleanable filters for dust removal from industrial flue gases and the recovery of valuable materials (bag/tube filters, cartridge filters or pocket filters) in accordance with international standards. The design of the AFC test 131 is based on the VDI 3926 Part 1, Version 2 and of the AFC 133 according to the new ISO 11057:2011. The ISO 11057 is based on the VDI 3926, ASTM D6830- 02 and the JIS Z 8909-1. These test rigs can also implement a customized filter media check with individual tests and configurable workflows. The control software runs under Windows and was developed by our company. It ensures easy operation of the test rig and the implementation of accurate, repeatable and traceable testing.
