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.
