Dust disperser
DIN EN779 | SAG 440 Topas GmbH

The SAG 440 dust disperser has been especially developed to meet the requirements as defined by the ASHRAE 52.2 and DIN EN779 standards for testing the performance of particulate air filters. Due to the particular physical properties of ASHRAE test dust it was necessary to adapt the instrument to this material. The 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.

- constant and reproducible dosing rate over a wide concentration range makes it suitable for several applications
- refillable during operation - optimal for long term tests
- optional remote control unit for manual or computer control

- ideal for testing the separation efficiencies of filters
- aerosol preparation for the determination of the filter dust holding capacity according to EN779, ASHRAE 52.2
- evaluation and calibration of dust samplers and monitors
