Aerosol Generators & Dispersers

    TSI Offers a Full Line of Aerosol Generators and Dispersers

    Aerosol generators and dispersers play a vital role in producing the aerosol required for an array of aerosol testing, production, and research. At TSI, we manufacture a full line of individual aerosol generators and dispersers capable of:

    • Producing monodisperse or polydisperse aerosols depending on the requirements of the application
    • Generating an aerosol in the form of a solid or a liquid
    • Providing an aerosol generation that can range from 3 nanometers (0.003 µm) to 200 µm in concentrations as high as 10 particles/cm³

    Solutions for a Wide Range of Measurement Applications

    Robust functionality in an aerosol generator or disperser is critical in applications such as general aerosol generation, filter testing, deposition of nanoparticles onto surfaces, automotive-cabin and ventilation air-filter tests, and vacuum-cleaner performance tests to name a few. For over 50 years, TSI’s aerosol generators and testing equipment continue to set the standard for these and other related aerosol generation and measurement practices. 

    Complete Aerosol Generation Systems from TSI

    In particular, TSI’s two complete aerosol generation systems, which include an aerosol generator and all of the required accessories, are the preferred choice of researchers in academia and industry. In fact, our customers, who include highly respected institutions from across the globe, have grown to trust TSI’s precision aerosol generation instruments for their accurate and reliable performance over the years.

    *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.
