Test of filter media according to EN 1822. Thomas Krinke & Hans-Georg Horn TSI Particle Seminars 2008. 2007, TSI Incorporated Outline Filtration Basics EN 1822 Short Overview Solution for EN 1822 conform characterization of filter media 2. 2007, TSI Incorporated filter Testing Introduction Downstream Concentration Penetration, P =. Upstream Concentration Efficiency, E = 1 - P. Most Penetrating Particle Size, MPPS: Typically between and m Mechanical media : 100 nm < MPPS < 300 nm Electro-Static and Membrane: MPPS < 100 nm 2007, TSI Incorporated Filtration Mechanisms Action of Brownian motion. Best capture with small particles, fine Diffusion fibers and low velocities. Independent of particle density. Interception Particles travel along streamlines and are caught because of their size.
