| ATM 231 | Moderate-output submerged Laskin-nozzle aerosol generator | Submerged Laskin-nozzle generator for robust high-flow liquid aerosol production | HEPA and ventilation-filter test benches, production QC and high-throughput aerosol challenge |
Key Features
Submerged Laskin-nozzle principle
Provides robust and repeatable liquid aerosol generation using a submerged nozzle arrangement.
High aerosol flow
Delivers 800–1,700 L/h for large test ducts and filter-test installations.
Extended operating time
The 100–500 mL liquid reservoir supports longer production and qualification sequences.
Low supply-pressure demand
Operates with compressed-air supply up to 2.5 bar for straightforward system integration.
