Analysis of Pressure Losses of Selected Filtration Materials

Abstract— With the increasing demands on the efficiency of filtration materials, it is essential to pay attention to the study of pressure losses that occur during the flow of air through these materials. This article presents a device design for measuring pressure losses, followed by experimental verification of selected filtration materials. From the individual measurements, permeability and resistance coefficient are evaluated, which are key for determining the filter's pressure parameters and its performance under real operating conditions.
