ABSTRACT:
A device for conditioning air has a pad formed of a plurality of layers of slit and expanded media, with the pad having a plurality of groups of layers therewithin. Each layer within a particular group of layers has its baffles oriented to face in the same direction, while each group is turned around to face in the opposite direction from its directly adjacent group so that the baffles of one group face oppositely to the baffles of the next adjacent group. Alternate layers within each group are expanded to a slightly different degree so that the various elements making up each layer support the elements of adjacent layers in spaced unnested relationship. The dimensions of the expanded cells are substantially greater than those of known prior pads to better accommodate higher air velocities.
