When air containing dust passes through the filter, the initialresistanceof the filter material rises along with the increase of filter dust.
当含尘空气通过过滤器时,滤料的初始阻力随滤尘增加而逐步上升。

The initialresistanceof the filter medium decides the air permeability of the filter medium itself, but the resistance during operating is several times to the initial resistance.
