The aerosol generator ATM 222 combines selected technical features of the generators ATM 220 and ATM 228 for long-term stable generation of test aerosols, calibration aerosols or process aerosols from pure liquids (oils like DEHS or PAO, water), solutions (salt solution, sugar solutions) and suspensions (A2, PSL). The generator complies to all requirements of VDI 3941-2.
The generator can be operated via a pneumatic coupling plug by compressed air or other pressurised technical inert-gases (e.g. with N2, CO2). For the purpose of a reproducible and long-term stable aerosol generation, the operational air flow is controlled via the pressure drop over the nozzle. This allows also a reproducible and stable operation of the generator even at very low air flow rates and thus also at lowest particle production rates.
For the dispersion of the substance to be aerosolised, the ATM 222 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.
