Dust Aerosol Generator 3410

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/m³). 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/m³.

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
• Accessory for model 3321 APS™ spectrometer often with 3302A diluter
• Accessory for model 3330 Optical Particle Sizer and 3340 Laser Aerosol Spectrometer

Features and Benefits

• Generation and de-agglomeration of dry particles as small as 0.2 µm
• Low (50 mg/m³) to high (160 g/m³) 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
