Model Overview
| Model | Group | Positioning | Core fit |
|---|---|---|---|
| ATM 240/S | Suspension aerosol generator with dryer — ventilation-filter testing | Generator for KCl and compatible suspension aerosols with integrated drying and a high coarse-particle fraction | ISO 16890 ventilation-filter efficiency testing and solid-particle challenge generation |
Key Features
KCl suspension aerosol
Generates a solid KCl test aerosol from a prepared suspension.
Integrated drying stage
Removes the liquid carrier before the aerosol enters the filter test duct.
Coarse-particle capability
Produces a relevant fraction above 1 µm for ventilation-filter efficiency measurements.
ISO 16890 workflow fit
Designed for integration into ePM filter test systems and standardised ventilation-filter procedures.
