The Dust Aerosol Generator Model 3410 disperses dry dust and powders for applications that need continuous and stable dosing with high accuracy. These defined test aerosols are commonly used in aerosol science, filter testing, industrial processes, and quality assurance tasks. The interchangeable dispersing units make it possible to disperse different materials (e.g. soot, TiO 2 , cellulose, or ISO 12103 test dust) at different output concentrations. A pressurized cover keeps the material dry even in locations with higher ambient humidity.

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.

FEATURES & BENEFITS

  • Generation and de-agglomeration of dry particles as small as 0.2 µm
  • Low (50 mg/m 3 ) to high (160 g/m 3 ) mass concentrations
  • Constant dosing independent of fill level in reservoir
  • Modular design, different feeding and dispersion units available
  • Dry powder generation even in humid environments

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
  • Accessory for model 3321 APS often with 3302A diluter
  • Accessory for model 3330 OPS and 3340 Laser Aerosol Spectrometer
