Abstract
The disclosed technology includes an axial fan assembly for an air handling unit of a heating ventilation and air conditioning (HVAC) system. The axial fan assembly can include an axial fan configured to direct air through the axial fan assembly, an inlet ring disposed in a flow path upstream of the axial fan and configured to direct air toward the axial fan, a stator disposed in the flow path downstream of the axial fan and configured to straighten a flow of the air, an outlet ring disposed in a flow path downstream of the axial fan and configured to direct air out of the axial fan assembly, and a fan deck configured to attach to the air handling unit and support at least the axial fan.

An air handling unit for a heating, ventilation, and air conditioning (HVAC) system, the air handling unit comprising:
- an enclosure having an inlet and an outlet;
- a heat exchanger coil housed within the enclosure and configured to (i) receive a refrigerant circulated through the heat exchanger coil and (ii) facilitate heat exchange between the refrigerant and air directed across the heat exchanger coil;
- and
- an axial fan assembly housed within the enclosure and configured to direct the air across the heat exchanger coil, the axial fan assembly comprising:
- an axial fan configured to direct the air through the air handling unit;
- an inlet ring disposed in a flow path upstream of the axial fan and configured to direct the air toward the axial fan;
- a stator disposed in the flow path downstream of the axial fan and configured to straighten a flow of the air;
- an outlet ring disposed in the flow path downstream of the axial fan and configured to direct the air out of the axial fan assembly;
- and
- a fan deck configured to support at least the axial fan in the air handling unit.
