ATM 228 Aerosol Generator
Atomizer Aerosol Generator ATM 228 for aerosol generation from liquids for mobile use, integrated compressor, pneumitic-controlled, remote controllable
Standards
Applications
- aerosol generation from pure liquids, solutions and suspensions
- integrity and recovery testing of HEPA/ULPA filters according to ISO 14644-3
- acceptance measurements for clean rooms, safety work benches and smoke detectors
- generation of calibration aerosols (e.g.: for particle counters) at low air flow rates
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.
