Model 340 HVVI™- High Volume
Virtual Impactors
 |
The
Model 340 HVVI is a high volume virtual impactor classifier
for size separation of aerosol particles. The 1130 L/min
(40- cfm) version has a cut-point diameter of 2.5 µm.
The 300 L/min version has available cut-point diameters of 2.5
and 1.0 µm. The device can be used to obtain
size-fractionated aerosol samples for air pollution research
and for industrial applications.
