Originální abstrakt

This work aimed to characterize ability of polypropylene hollow-fiber membranes (HFM) to remove solid (dust) particles from air. This was carried out by measuring penetration of the HFM, i.e. ratio of particles downstream and upstream of the HFM in an outside-in configuration (suction mode) together with measuring pressure drop. HFM bundles with a filtration area of 0.8 square meters and pore size 0.1x0.5 um were used. The results showed high separation efficiency for submicron particles, comparable with HEPA filters. Compared to air filters based e.g. on non-wovens, these have higher pressure drop.
