Abstract: A ceiling fan blade assembly structure includes a blade holder, multiple fan blades, and multiple locking assemblies. Multiple fan blade assembly portions are disposed at an outer side of the blade holder. Each fan blade assembly portion includes two first side plates parallel to each other, a first radial positioning portion, and two first vertical positioning portions disposed on the two first side plates. Each fan blade has a fan blade connection portion that includes two second side plates, a second radial positioning portion, and two second vertical positioning portions. The second and the first radial positioning portions are engaged with each other, and the two second and first vertical positioning portions are engaged with each other. Accordingly, the fan blade connection portion is preliminarily positioned on the fan blade assembly portion. Through the locking assembly, the first and the second radial positioning portions are locked together.

Abstract: Disclosed is an Air Handling Unit, AHU, including a fan inducing a flow in an air ventilation ducting system. The fan includes a front disc, a back plate and fan blades manufactured as separate units. The fan provides a radial or mixed flow. The fan blades have an upper edge including upper attachment protrusions attached to the front disc and a lower edge including lower attachment protrusions attached to the back plate. The fan blade includes at least two upper and lower attachment protrusions protruding through the front disc and back plate indentations, respectively, forming axial retainers. An axial locker on the protruding portion provides a retaining axial force between the front disc and the back plate. The fan further includes another other upper and lower attachment protrusion cooperating with front disc and back plate indentations, respectively, forming radial retainers preventing the blades from dislocating in the radial direction.
