How to model a Centrifugal fan (radial/blower) with available fan curve? The flow is coming axially and going out radially (perpendicular to the incoming flow).

I have a centrifugal fan (also people call blower, radial fan etc). The flow is coming from both side axially and leaving radially through one volute/duct. I have manufacturer supplied fan curve. How do I model the fan (inlet, outlet)? All examples/tutorials available are for axial fan. Have anyone did this kind of simulation before? I am not talking about the rotating region (MRF) model, because I do not have fan blade. Thank you!
