Fan and Blower Design


  • Design different types of ventilators in a specific speed range 8 < nq < 500 (EU), 400 < Ns < 22,000 (US)
  • Create complete pump stages from different single components such as impellers, vaned and unvaned stators, and volutes
  • Use a fully parametric geometry model of the ventilator that can be the basis for design exploration and optimization
  • Export the 3D model for further applications like flow simulation (CFD), finite element analysis (FEA), mechanical design (CAD), and rapid prototyping


Design ventilator impellers according to your specific needs. The underlying design theory is based on fundemental equations and the latest empirical correlations.

Design the volute while the ventilator type is centrifugal. Outflow conditions of the previously designed impeller or radial diffuser are automatically taken into account.

Vaned and unvaned stators complete the flow channel of the ventilator stage. Additionally, unvaned stators may be used to prepare a model for flow simulation.
