Atomizer Aerosol Generator Aerosol generation into pressurised vessels up to 10 bar  Polydisperse aerosol mainly below 1 μm  Excellent stable particle size distribution  By variation of nozzle pressure, the particle production rate can be adjusted on a wide range  Suitable for producing latex aerosols Applications  Aerosol generation against overpressure  Test of HEPA and ULPA filter and filtermedia  Approval of Cleanrooms  Flow visualization Atomizer Aerosol Generator ATM 210 The ATM 210 aerosol generator produces aerosols with known properties in accordance with the guideline VDI 3491. This special model facilitates generation of aerosols into pressurised vessels (up to 10 bar). Its design ensures a highly stable particle size distribution and concentration with high reproducibility and a high aerosol output. The essential part of the ATM 210 is a new 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 dependant particle size distribution mainly below 1 μm. The necessary compressed air is cleaned by a HEPA-filter. A pressure reducer and a manometer facilitate regulation of the atomizer pressure. A level indicator outside the atomizer vessel allows the user to check the liquid level during operation. The generator is suitable for various liquids, e.g. DEHS or PAO (Emery 3004). It can also be used to disperse PSL reference materials. The ATM 210 is designed for use with an external pressurised air supply. Pressure reducer and manometer are so positioned that the instrument can be easily and safety operated. The liquid reservoir is arranged inside the chassis of the generator. For safety requirements a protection valve has been installed in the liquid reservoir. All fluid components are certified for pressures up to 20 bar.

Technical Data The ATM 210 is available as a standard and a high flow model (ATM 210/H). The only difference between both instruments is the design of the stainless steel atomizer nozzle (protection of utility model), which can be easily changed by the user. The aerosol output of the ATM 210/H is nearly ten times higher than that of the standard model (see specification).
