Any 3D models of blowers online
 

Hello,

I'm looking for a 3D model of a centrifugal blower with a matching pressure vs. flow performance curve. I want to use it to practice validating CFD to experimental data. Is there anything like this online?

I'm finding (not surprisingly) that most manufacturers provide 3D models that have the outermost "shell" of the model to the correct dimensions, but the model has a "dummy" impeller that does not reflect their actual design.
