Aerosol generation is realised by a brushless compressor. Accordingly, no external compressed air supply is required. For the purpose of reproducible and long-term stable aerosol generation, the air flow rate is controlled via the pressure drop over the nozzle. This allows also a reproducible and stable generator operation even at very low air flow rates and thus also at lowest particle production rates.

Benefits

  • stable aerosol generation even at lowest particle production rates
  • safe and reproducible adjustment of operating points
  • suitable for mobile operation (internal compressor, optional battery operation mode)
  • remote control via serial interface (optional)

Applications

For the dispersion of the substance to be aerosolised (aerosol substance), the ATM 228 is equipped with a two-substance nozzle designed by the Topas GmbH. The nozzle is operated within or above the aerosol substance (submerged or non-submerged operation mode) and consists of two inlet ports for the supply of air as well as aerosol substance and one outlet port for the generated primary aerosol.

The supply of a defined air flow rate causes a negative pressure at the nozzle inlet port for the aerosol substance. The aerosol substance flows thus into the dispersion zone of the nozzle, where aerosol substance and gas flow converge and form a droplet aerosol.
