The Aerosol Generator ATM 241 produces droplet aerosols with known properties according to the guideline VDI 3491.
Standards
VDI 3491-2
VDI 2083
ISO 14644-3
The designs and technical solutions warrant highly constant particle size distribution as well as particle concentration with high reproducibility and a high aerosol output.
The generators of series ATM 241 enable to atomize various liquids, for example PAO (Emery 3004), DEHS, PSL-suspensions, and saline solutions (limited suitability).
Benefits
- polydisperse aerosol mainly below 1 µm
- excellent constant particle size distribution
- defined and high particle number concentration
- by varying of nozzle pressure and the number of switched-on nozzles one can adjust both particle production rate and within narrow limits the particle size distribution
Applications
- Generation of tracer particles
- Verifying measurements in very large clean rooms
- Test of HEPA and ULPA filter media
Accessories
- aerosol substance DEHS
- further aerosol substances e.g. PAO (Emery 3004) on request
