Mask Bacterial Filtration Efficiency (BFE) Detector
ASTMF2299/ASTMF2299 03(2017), EN14683-2019,ASTMF2101-19
Product overview:
This PFE testing machine is used to measure the bacterial
filtration efficiency (BFE) of medical face mask materials,
employing a ratio of the upstream bacterial challenge to downstream
residual concentration to determine filtration efficiency of
medical face.
Standards:
ASTMF2299/ASTMF2299 03(2017), EN14683-2019,ASTMF2101-19.
Technical Parameters:
