Abstract
A plenum of distributing a flow of air from an air source includes ports extending from a face element of a body. The ports are configured to direct the flow of air out of the plenum, and the ports are arranged on the face element in a first row having first length, a second row having a second length, and a third row having a third length. The first row is positioned proximate to the top element, the third row is positioned proximate to the bottom element, and the second row is positioned between the first row and the third row. In addition, the second length is greater than the first length and the third length, and a shape of the face element is configured to accommodate the first length of the first row, the second length of the second row, and the third length of the third row.
