ATM 228

The ATM 228 is a further development of the highly sucsessful ATM 226 aerosol generator and fully complies with the requirements of VDI 3491-2.

According to ISO 14644-3 this device can be used to test the filter integrity of HEPA and ULPA filters as well as measuring the recovery time. It can also be used in the test of very small filter cross sections where very low aerosol quantities are required. The ATM 228 has been developed for particularly stable aerosol generation at low nozzle volume flows or nozzle pressures.

The advantage of the generator lies in a very wide adjustable concentration range with highest aerosol stability. Thus an optical cleanroom particle counter can be operated directly on the ATM228 without dilution system below the coincidence limit.

Advantages

• Very wide working range with exact reproducible adjustable particle production rate
• Accurate setting of minimum aerosol volume flows
• Digital display
• Interface for external control
• Internal brushless compressor
• Mains connection with integrated wide-voltage power supply
• Optional operation in battery mode

Options

• External battery pack
• Interface control via serial connection
