Abstract:
1. An air filtration device for intake of atmospheric air, removal of contaminants from the atmospheric air, expulsion of filtered air, and configured for operational association with a generally vertically oriented surface, said air filtration device comprising: a housing defining an air flow path therethrough and having a front surface and a rear surface; at least one air inlet formed in said front surface; at least one air outlet formed in said housing intermediate said front surface and said rear surface, said at least one air outlet extending on a side surface located between the front surface and the rear surface for cooperation of said air outlet with a generally vertical surface to which said air filtration device is associated for enhanced dispersion of filtered air expelled through said air outlet; a filter supported in said air flow path; an impeller supported by said housing for moving air through said air flow path, said impeller including a central inside area; a baffle plate supported by said housing for directing air flowing from said air inlet toward said central inside area; and a motor for driving the impeller, the motor and impeller at least partially supported by the baffle plate.
