Atomizer Aerosol Generators
ATM 220 and ATM 226
Advantages
•
Polydisperse aerosol mainly below 1µm
•
Excellent constant particle size distribution
•
Defined and high particle number
concentration
•
ATM 226 with stainless steel housing
Applications
Atomizer Aerosol Generator ATM 226
•
Testing of HEPA and ULPA filter media
Atomizer aerosol generators of series ATM 220
and ATM 226 provide generation of test aerosols
with defined properties (according VDI-guideline
3491). Its design and technical solution warrants
highly constant particle size distribution as well as
particle concentration with high reproducibility.
The generators enable to atomize various liquids,
for example DEHS, PAO (Emery 3004) and saline
solutions. The aerosol generators can also be used
for generation of PSL-standards.
The generator ATM 220 is designed as an
instrument with external compressed air supply,
whereas the ATM 226 has a low-noise compressor
producing the compressed air. All aerosol
generators are characterised by compact and
robust design. Operating controls, connectors and
indicators are so installed, that the instrument can
be easily and safe operated.
With its stainless steel housing the ATM 226 is
excellent qualified for measurements in clean room
environments.
•
Clean room measurements and certification of
laminar flow boxes
•
Generation of tracer particle at low
flow rates
•
Visualisation of flows
Adjustable Particle Production Rate
The adjustment of the volumetric flow rate can be
done for ATM 226 with the integrated needle valve
and is shown on the integrated flow meter. Lower
volumetric flow rates will lead to a reduced particle
production rate.
Compressed air operated atomizer aerosol
generators of series ATM can vary the particle
production rate by regulation of nozzle pressure.
