ABSTRACT:
A filter system particularly adapted to remove particulate aerosol and vapor contamination from air comprising, an outer shell having a contaminated air inlet cap connected to one end and a clean air outlet cap connected to the other end, and a plurality of filter units mounted axially in the shell, each of said units comprising two containers, one of the containers having a particle/aerosol filter element therein such as paper, and the other of the containers having a vapor filter element therein, such as charcoal, the two containers of each filter unit being positioned in contiguous relation. A vapor passage is provided from one container to the other container of each unit and an annulus is provided between the outer periphery of the containers and the inner surface of the shell. A plurality of elongated inlet conduits is provided in the annulus, each of the respective conduits defining an inlet passage to the one container of each of the filter units, and a plurality of elongated outlet conduits is provided in the annulus, each of the outlet conduits defining an outlet passage from the other container of each of the filter units. The inlet conduits communicate with the inlet cap and the outlet conduits communicate with the outlet cap.
