Atomizer Aerosol Generator ATM 221 for aerosol generation from liquids, compressed air operated, base model with submerged nozzle
The aerosol generator ATM 221 provides aersols with low particle numbers.
For applications where a very precise setting of smaller particle production rates are required (up to 0,6 g/h), the model ATM 221 was developed.
A further range of application for aerosol generators is calibration of measuring.
The atomizer is the key part of the ATM 220. It is made of high quality stainless steel and works as a two-stream nozzle, based on the injection principle. The unique feature is that the outlet points towards the wall of the glass vessel which works as the baffle plate. This particle impaction section removes coarse spray droplets and results in a particle size distribution mainly below 1 µm. The air is cleaned by a HEPA-filter before it is introduced to the atomizer.
At the aerosol generator ATM 221 the nozzle is immersed in the liquid in order to ensure setting of small mass flows with a very high reproducibility.
