Air handling device

Abstract

An air handling device includes a plurality of tunnels defining a plurality of separate air flow pathways. At least one tunnel of the plurality of tunnels is an active tunnel and at least one tunnel of the plurality of tunnels is a redundant tunnel. The air handling device further includes a first air select at a first end of the plurality of tunnels and a second air select on a second end of the plurality of tunnels, wherein the first end is opposite to the second end. The air handling device also includes a plurality of dampers within each of the first and second air selects, wherein the plurality of dampers are configured to change an air flow therein to block air flow through the active tunnel and allow air flow through the redundant tunnel.
