ATM 221 Liquid Aerosol Generator
Low-output submerged-nozzle aerosol generator for stable and reproducible liquid aerosol production where low particle concentration and fine adjustment are required.
Model Overview
| Model | Group | Positioning | Core fit |
|---|---|---|---|
| ATM 221 | Low-output liquid aerosol generator — submerged nozzle | Submerged-nozzle atomizer for reproducible liquid aerosol generation at low particle output | Low-concentration aerosol tests, instrument studies and compact laboratory setups |
Key Features
Low particle production
Designed for applications requiring lower aerosol concentrations than conventional high-output atomizers.
Submerged-nozzle principle
The immersed two-substance nozzle provides stable atomisation and repeatable output.
Simple pressure adjustment
Aerosol concentration can be adjusted through the supplied operating pressure.
Compact reservoir
A 40–80 mL working volume supports practical laboratory operation with limited test liquid.
