    Research of the influence of filter element resistance on the powered air-purifying respirator service life by D. Slavinskyi, T. Bilko, Yu. Cheberyachko, S. Vambol, O. Yavorska

    Published 2024-11-01
    “…The following parameters of the simulation model of a powered air-purifying respirator were substantiated: controlling action – fan rotating speed, restrictions on air flow and air pressure in the respirator mask (depending on the mode of working arrangements of the user), concentration of dust in the air of the working area, capacity of the power source, power consumption of the electric motor of the fan and control system components, parameters of filter elements (fibre packing density, filter layer thickness, fibre diameter, etc.), input concentration of dust aerosol, which made it possible to establish the relationship between the value of the filter element resistance and the time to complete discharge of the power source. …”
