Much of the previous laboratory research that forms the basis of aerosol sampler performance and inhalation efficiency is based on experiments carried out in calm air or at wind speeds above 50 cm/s. In most workplaces however, it has been shown that air velocities are typically much lower than this. An ultralow-speed wind tunnel has been developed to perform experiments at more realistic wind velocities in order to better characterize aerosol behavior in actual workplaces. The tunnel operates at windspeeds between 5-50 cm/s with uniform air velocity and uniform aerosol distribution for the range of aerodynamic particle diameter 0-100 um.
