ABSTRACT:
An apparatus and a method are provided for producing a solid particulate aerosol which is sufficiently precise in concentration to be suitable for testing HEPA filters. The apparatus continuously delivers a measured quantity of a solid particulate material to a mixer where it is combined with a controlled flow of gas. The solid particulate material is delivered to the mixer in precisely measured quantities via pockets of constant volume which are disposed radially and equidistantly about a rotating wheel.
