Abstract
A high performance through-air apparatus is provided. The though-air apparatus includes a through-air roll configured for rotational movement about a first axis, and a high flow circuitous air path inside of the apparatus that includes a path extending through a supply conduit, through the through-air roll, and also through an exhaust conduit. The through-air apparatus also includes a plurality of turning vanes positioned within the high flow circuitous path positioned to guide the flow of air through the apparatus. The through-air apparatus has a length, a width, a height, which together define a volume having a compact configuration. The high flow circuitous air path inside of the apparatus has a length, where the ratio of the volume of the through-air apparatus to the length of the high flow circuitous air path is less than 20 m.
