Bio-aerosol generation transmission and sampling train: The BLAM Aerosol generator hosts the SARS-CoV-2 suspension, receives an air flow from the AERO nebulizer pump (out of the figure), generates the bio-aerosol that is transmitted through the Aerosol transmission tube, and it is collected in the vessel of the Biosampler. The air flow is disinfected by passing into a NaClO impinger trap, and dried by a SiO₂ dessicator, before entering a BioBravo pump (out of the figure) that sustains the sampling. Pink arrows show the path followed by SARS-CoV-2 aerosol.
