Descripción
The objective is the study of filtering tissue permeability and the characterization by means of permeability tests, of the process of coal particles retention in breath protection filters.The permeability of nine probes have been measured against particles P1, P2 and P3, with a fixed test depression of 60 Pa, before and after being used in an atmosphere containing a suspension of coal dust. Brand new filters (from factory) have different mean values of permeability to the air flow; its value doubles when the efficiency class is changed from P3 (Rm: 0,13) to P2 (Rm: 0,27) and to P1 (Rm: 0,54). In addition, after a time period of use of 120 minutes, the permeability of the filter decreases due to air particles capture, being such a diminution higher in class P2 filters (4,32 %) respect to class P1 ones (2,68%) and even lesser in class P3 ones (0,38 %).
