- long-term stable generation of aerosols
Applications
- generation of polydisperse aerosols, mainly submicron (
- long-term stable generation of aerosols
The essential part of the ATM 210/H is an atomizer nozzle made completely of stainless steel. It works as a two-stream nozzle based on the injection principle and is combined with a baffle placed close to the spray outlet. This integrated particle impaction section removes coarse spray droplets and results in a number dependent particle size distribution mainly below 1 µm. Depending on the flow rate, the cut point of the impactor varies, but this has quasi no impact on the submicrometer range of the particle size distribution of the aerosol.
The necessary compressed air is cleaned by a HEPA-filter. A pressure reducer and a manometer facilitate regulation of the atomizer pressure between 0 and 15bar. A level indicator outside the atomizer vessel allows the user to check the liquid level during operation.
