Media arrangement and aerosol loading characteristics of panel filters

The effect of media arrangement within fibrous filter units on aerosol and dust loading characteristics has been studied. The behaviour of the media alone was measured. This was then compared with the performance of two units in which the media geometrical arrangement differed substantially. The effects which can be attributed specifically to media arrangement were thus isolated. An "ideal" model of a pleat type filter unit in which the dust distribution is uniform is proposed.
