ABSTRACT:
An adsorption bed arrangement includes a plurality of adsorption elements, a housing, and a gasket member. Each of the adsorption elements has a first adsorptive media and a second adsorptive media, which remove different contaminants from an incoming air stream. For example, the first adsorptive media removes acidic contaminants and the second adsorptive media removes basic contaminants. The housing defines an interior, a plurality of inlet openings, and a plurality of outlet openings. The adsorption elements are positioned within the housing interior and the housing is selectively openable to provide access to the adsorption elements. A method for changing the media includes removing an access panel from the adsorption bed housing to expose a cover member covering an end of an adsorption element; removing the cover member to expose media within the element; and pouring the media from the element.
