BFE (Bacterial Filtration Efficiency) and VFE (Viral Filtration Efficiency) Bio Kit Bioaerosol Sampling System, allows to be in compliance with all the requests for BFE % efficiency test (Bacterial filtration efficiency), VFE Viral Filtration Efficiency test and breathability test (Pa/cm²) for medical face mask materials according to the EN14683 as well as according to ASTM 2100 and ASTM 2101. BFE Bio kit is also done for EN ISO 9237 for measuring the permeability of fabrics to air and it is applicable to most types of fabrics, including industrial fabrics for technical purposes, nonwovens and made-up textile articles that are permeable to air.
How to proceed the Bacterial Filtration Efficiency (BFE) and VFE Viral Filtration Efficiency Testing
EN 14683 (Annex B) – ASTM 2101
Fill in the aerosol generator with the bacteria suspension to nebulize;
Set up the multi stage cascade impactor and connect the sampling pipe;
Connect the atomization chamber to the impactor;
Connect the condenser at the impactor output suction line;
Connect the output of the condenser to the sampler, setting a 28,3 l/min flow;
