Aerosol Generators & Dispersers

    Full Line of Aerosol Generators and Dispersers

    Aerosol generators and dispersers play a vital role in producing the defined aerosol required for an array of aerosol testing, production, and research. Applications requiring aerosol generation are very diverse, and include, but are certainly not limited to, filter testing, deposition of nanoparticles onto surfaces, vacuum-cleaner performance tests, and calibration of aerosol instruments.

    At TSI, we manufacture a full line of individual aerosol generators and dispersers capable of:

    • Size: 3nm - 200 µm
    • Concentration: as high as 107 particles/cm3
    • Composition: solid (dissolved or suspended), liquid or powdered
    • Size distribution characteristics: monodisperse or polydisperse


    Take a look at the table below to help you get started.

    Polydisperse Generator 9307/9306-6 0.01 to 2.0 (nominal 0.3-μm count mean diameter) >10⁷/cm³ 30/1000
    Polydisperse Generator 8108 0.1 to 10.0 10⁴/cm³ 140

    *May be used to disperse monodisperse solid particles such as PSL.
    †Large sizes require optional orifices.‡Aerodynamic diameter.
    §High concentrations require optional high-speed motor.
    **Includes dilution air; nominal dispersion air flow rate is 1.5 L/min.
    ††Flow rate at 25-psig inlet pressure; higher pressures and flow rates possible.
