PRODUCT DETAILS
The Dust Aerosol Generator Model 3410 comes in two versions that differ in the way the powder is fed to the disperser.
Model 3410U is for poorly flowing powders at low dosing rates (>50 mg/m 3 ). Here the powder is continually poured onto a metal ring where excess material falls off the side and back into the reservoir.
Model 3410L meters powder using a moving toothed belt. The well-defined spaces between the teeth ensure a constant and reproducible supply of powder and achieve mass concentrations of 0.5 to 160 g/m 3 .
Both versions disperse the powder via an ejector nozzle with ceramic inlay to make it more resistant against abrasive material. Shear forces in the ejector nozzle disperse and de-agglomerate particles. In both models the reservoir can be refilled while in operation to accommodate any required dosing interval.
APPLICATIONS
Instrument calibration and validation
Aerosol research
Tracer particles for laser velocimetry LDV, PIV, V3V (seed particles)
Inhalation and toxicology studies
Filter Testing
Dust holding capacity tests
