ATM 221/D Suspension Aerosol Generator
Suspension aerosol generator with a removable dispersion unit and magnetic stirrer for reproducible particle aerosols used in PM-sensor calibration, validation and filter-testing workflows.
Model Overview
| Model | Group | Positioning | Core fit |
|---|---|---|---|
| ATM 221/D | Suspension aerosol generator — stirred dispersion | Generator for reproducible aerosolisation of particle suspensions with removable dispersion unit and magnetic stirring | PM-sensor calibration, particle-instrument validation and suspension-based filter testing |
Key Features
Suspension aerosolisation
Atomises particle suspensions for solid-particle aerosol generation after downstream drying.
Integrated magnetic stirring
Maintains a more uniform suspension concentration during longer test sequences.
Removable dispersion unit
Facilitates filling, cleaning and changeover between aerosol substances.
Adjustable operating range
Supports 200–750 L/h aerosol flow for calibration and test-system integration.
