ATM 230 – High Output

ATM 230 – High Output

The Atomizer Aerosol Generator ATM 230 produces droplet aerosols with known properties according to the guideline VDI 3491. Its design and technical solution warrants highly constant particle size distribution as well as particle concentration with high reproducibility and a high aerosol output.
The generator enables to atomize various liquids, for example PAO (Emery 3004), DEHS, salt solutions, PSL-standards suspensions.

The collision nebulizer ATM 230 is designed as a serial instrument with a external pressure-air supply. Operating controls are so installed, that the instrument can be easily and safely operated. 
The liquid reservoir is arranged inside the chassis of the generator.


  • Polydisperse aerosol mainly below 1 µm
  • Excellent constant particle size distribution
  • Defined and high particle number concentration
  • By varying of nozzle pressure adjusting of particle number concentration in a wide range


  • Testing of HEPA and ULPA filter media
  • Clean room measurements and certification of laminar flow boxes
  • Generation of tracer particle at low flow rates
  • Visualization of flows
