Useful for a variety of applications, the Fluidized Bed Aerosol Generator Model 3400A aerosolizes dry powders and dusts. Using bronze beads to break up powder agglomerates, the 3400A generates a constant output in terms of aerosol concentration and size distribution. It is used in various applications such as filter testing, inhalation toxicology testing, and providing seed particles for laser-velocimetry.

TSI’s Fluidized Bed Aerosol Generator Model 3400A* contains a fluidized bed chamber and a powder reservoir. The fluidized bed consists of 100-μm bronze beads supported by a porous screen that allows clean, dry air to pass through, yet prevents the passage of any powder.
During operation, a bead chain meters powder into the fluidized bed. As air forces its way up through the screen and into the bed, it creates a boiling action, which deagglomerates the powder and causes it to be carried upward by the airflow through a vertical elutriator.
A cyclone at the top of the vertical elutriator prevents any particles that are not fully deagglomerated from being dispersed. With a flow rate of 9 liters/min, the cyclone allows only respirable dust† to be generated. Separate flowmeters measure the bed flow rate and the bead purge flow rate.
The powder reservoir is equipped with a gear-driven rake that rocks back and forth, preventing the formation of a channel in the powder due to the movement of the bead chain through the powder reservoir. This assures a constant, even feed rate into the fluidized bed chamber. The airflow pattern through the porous screen further stabilizes the concentration of the output aerosol.
