ATM 231
Atomizer Aerosol Generator ATM 231 for aerosol generation from liquids, compressed air operated, submerged nozzle, high mass flow rates
The Atomizer Aerosol Generator ATM 231 produces droplet aerosols with known properties according to the guideline VDI 3491-2.
The ATM 231 is designed as a serial instrument with external compressed air supply. The liquid resservoir arranged within the housing.
The ATM 231 provides a moderat aerosol output for long operation time. Its design and technical solution warrants highly constant particle size distributions as well as particle concentrations with high reproducibility.
The ATM 231 is able to aerosolise various liquids, for example PAO (Emery 3004), DEHS, salt solutions, PSL-standards suspensions.

Benefits
- polydisperse aerosol, mainly submicron (< 1 µm)
- excellent stability i generation of particle size distribution and concentration
- by varyation of the nozzle pressure, the production rate can be adjusted in wide range
Applications
- testing of HEPA and ULPA filter media
- visualization of air flows (tracer particles)
The ATM 231 is equipped with a Laskin nozzle for aerosol generation. The required compressed air is HEPA filtered.
