1. An air handling device comprising:
- a fan including a fan hub and a set of fan blades that extend from the fan hub, the set of fan blades defining a fan diameter and the fan hub defining a hub diameter, wherein the fan has an inlet side for air intake and an outlet side for air discharge;
an annular fan inlet passage arranged at the inlet side of the fan; and
an annular fan outlet passage arranged at the outlet side of the fan, the fan inlet passage and the fan outlet passage each defining an outer diameter that is substantially equivalent to the fan diameter and an inner diameter that is substantially equivalent to the hub diameter.

Abstract
An air handling device includes a fan that has a fan hub and a set of fan blades that extend from the fan hub. The set of fan blades defines a fan diameter and the fan hub defines a hub diameter. The fan has an inlet side for air intake and an outlet side for air discharge. An annular fan inlet passage is arranged at the inlet side of the fan, and an annular fan outlet passage arranged at the outlet side of the fan. The fan inlet passage and the fan outlet passage each define an outer diameter that is substantially equivalent to the fan diameter and an inner diameter that is substantially equivalent to the hub diameter.
