Page 7: Safety
Safety The atomizer aerosol generator Model 3079A is an instrument for producing test aerosols with known properties (according to guideline VDI 3491) e. g., for filter testing and for validation of cleanrooms. Appropriate aerosol substances are fluids, preferably DEHS and Emery 3004 (PAO) (size of the generated particles mainly in the range of 0.1 to 0.3 µm). - Page 8 Safety (This page intentionally left blank) Model 3079A...

- Page 13 Product Description The newly developed atomizer is the key part of the Model 3079A (registered design GS 9408604.4). It is made of high-quality stainless steel and works as a two-stream nozzle, based on the injection principle. The unique feature is that the outlet points towards the wall of the glass vessel which works as the baffle plate.

Figure 6: Measurement Results of a 2,02 µm PSL Aerosol Production of PSL aerosols with the Model 3079A is possible up to particle sizes of 3 µm. Due to the excellent separation characteristics of the integrated baffle it is possible to prevent the formation of agglomerates. -
Page 22: Generation Of Tracer Particles
Generation of Tracer Particles The continuous and stable generation of particles is important when using optical methods for measuring flow velocities and distributions. The Model 3079A meets these requirements and makes it also suitable for tracer particle generation. Generation of Salt Aerosols The Model 3079A Atomizer Aerosol Generator is also suitable for salt aerosol production. -
