The Dust Disperser SAG 440 has been especially developed to meet the requirements as defined by the guidelines ASHRAE 52.2 and DIN 16890-3, EN 779 for testing the performance of particulate air filters.
Due to the particular physical properties of ASHRAE test dust the instrument was adapted to this material. The dust feeder SAG 440 is particularly suited for feeding / dosing dusts containing a certain proportion of fibres and provides excellent results when producing test dust to check separation efficiencies.
To generate a test aerosol a defined amount of test dust is put on the feeding belt, the dosing wheel adds a set quantity to the dust uptake nozzle from where it is forwarded pneumatically to the test duct. To avoid electrostatic effects it is possible to discharge the particles with the Bipolar Aerosol Neutralizer Unit EAN 581 from Topas.
