Aerosol Generator ATM 228

The aerosol generator ATM 228 is a further development of the ATM 226 aerosol generator and serves for the mobile generation of test and calibration aerosols from pure liquids, solutions and suspensions. The generator complies to all requirements of VDI 3491-2.

Standards

Aerosol generation is realised by a brushless compressor. Accordingly, no external compressed air supply is required. For the purpose of reproducible and long-term stable aerosol generation, the air flow rate is controlled via the pressure drop over the nozzle. This allows also a reproducible and stable generator operation even at very low air flow rates and thus also at lowest particle production rates.

Benefits

• stable aerosol generation even at lowest particle production rates
• safe and reproducible adjustment of operating points
• suitable for mobile operation (internal compressor, optional battery operation mode)
• remote control via serial interface (optional)

Applications

• aerosol generation from pure liquids, solutions and suspensions
• integrity and recovery testing of HEPA/ULPA filters according to ISO 14644-3
• acceptance measurements for clean rooms, safety work benches and smoke detectors
• generation of calibration aerosols (e.g.: for particle counters) at low air flow rates
