Thanks to a range developed for each type of application, ATI offers TDA 4B, TDA 4B LITE cold generators but also stand-alone versions with integrated compressor TDA 6D especially dedicated for PSM, laminar flow hoods and filter boxes.

For cleanrooms the need for higher aerosol generation requires a TDA 5D thermal generator with a positive displacement pump if required.

In combination with the TDA 2i photometer or a dilutor to perform a particle counter test according to the methods described in ISO 14644-3, the ATI system allows the use of different types of aerosol generation (PAO Emery 3004 – DEHS – Ondina).


  • Aerosol Diluter ATI – TDA D10 / TDA D100

    . Compatible with any 1 cfm particle counter.
    . Minimizes pressure drops and aerosol loss.
