1. A compact assembly for an air handling unit, comprising:
a mixed-flow fan having a rotor with a plurality of blades to move air from an upstream side of the mixed-flow fan to a downstream side, wherein the mixed flow fan has a diffusion factor of at least 0.6;
a wide-angle diffuser having a hub-to-tip ratio below 0.5, a diffusion factor of at least 0.6, and a plurality of vanes coupled to the downstream side of the mixed-flow fan;
a first high resistance media coupled directly to the upstream side of the mixed-flow fan and positioned no farther from the plurality of blades than fifteen percent of a mean chord of the plurality of blades; and
a second high resistance media coupled directly to the wide-angle diffuser and positioned no farther from the plurality of vanes than a five percent of a mean chord of the plurality of vanes.
