Industrial Aerodynamics & Ventilation Case Study

Industrial Centrifugal Blower Fan

Aerodynamic CFD airflow simulations, backward-curved blade geometry design, and dynamic rotor balancing adhering to AMCA 210 and ISO 5801 standards.

Centrifugal Fan Assembly

Aerodynamic Design & Rotor Dynamics:

Engineered to produce high static pressure differentials with minimal acoustic emissions for industrial dust collection and heavy ventilation duct systems. Backward-inclined airfoil blades were chosen for their non-overloading horsepower characteristic and peak aerodynamic efficiencies reaching 82%.

Key Engineering Highlights:

  • Dynamic impeller balancing certified to ISO 1940 Grade G2.5 for vibration-free continuous operation.
  • Logarithmic spiral volute scroll design reducing air turbulence and pressure drop.
  • Sheet metal fabrication shop drawings with laser-cutting nested profiles and welded seam specifications.
