Abstract
A filter assembly for an exhaust stack having a housing defining an interior chamber and an inlet and an outlet which are connected in series with the exhaust stack. A mounting frame is secured diagonally within the interior of the housing so that the mounting frame is interposed between the inlet and outlet of the housing. A plurality of filter elements are detachably secured to the mounting frame so that influent into the housing inlet passes through the filter elements prior to exhaust out through the housing outlet and to the atmosphere. The filter assembly is easily retrofitted to existing systems by severing and removing a portion of the stack and installing the filter assembly in its place.
