1 Introduction
The Model 3079A Atomizer Aerosol Generator is an instrument for producing test aerosols with known
properties according to German guideline VDI 3491. When DEHS is used as aerosol substance the
instrument is suitable for use as verifying instrument in cleanrooms according to standards VDI 2083
and EN 14644. The generated particles are in the range of the Most Penetrating Particle Size (MPPS)
between 0.1 and 0.3 µm and thereby guarantee a safe evaluation of high performance filters.
The design and implemented technological features guarantee the production of aerosols with
constant particle size distribution and concentration with a high reproducibility.
The Model 3079A can also produce Latex or salt aerosols. In this case, a diffusion dryer Model 3062 is
recommended to be used downstream of the aerosol generator in order to remove remaining water
droplets or prevent their formation.
