Filter Media Tester
Overview
ISO 11057/VDI 3926 filter media tester is design for the determination of particle concentration, dust penetration, cycle time, pressure drop, residual pressure drop, fractional efficiency, gravimetric separation efficiency of filter media. The test rig allows testing of specific filter media for cleanable filter for dust removal from industrial flue gases and the recovery of valuable materials in accordance with international standards.
It is professional designed for filter media to be used in cleanable filters, e.g. baghouse filters, pocket filters, cartridge filters. By simulating local filtration and cleaning conditions of a filter element, filter media testing system provides constant and reproducible manner loading of the filter sample with test dust.
