Filtration of nanoparticles: Presentation of FANA test bench
Résumé
A test bench for the analysis of air filter penetration has been developed at IRSN. The paper introduces this nano-aerosol filtration test bench (FANA) and the methodology used to measure filter penetration as accurately as possible for nanoparticles. Two configurations are compared by measuring the penetration through a metallic grid. The results obtained are identical. In addition, penetration results using two filtration velocities and a particle size range of 2.5 to 400 nm are presented for different types of filtration media (F6, F9, HEPA).
