Impeller design from the global leader in industrial fan blades

Multi-Wing America’s impeller design is a direct result of the HVAC, Refrigeration, Engine Cooling and Radiator markets we have served for almost 40 years. Our impeller design process relies on a combination of state-of-the-art fan engineering and grassroots experience in an array of industrial applications around the world. That process includes Solid Works CAD system software, our Rapid Prototyping Machine, Finite Method Analysis, our Wind Tunnel, and generations of experience in impeller design across a global staff of axial fan engineering experts.

Multi-Wing’s impeller design process uses the three-dimensional CAD system Solid Works® in an effort to use 3D models and eliminate any errors in interpretation or potential issues with toolmakers and suppliers. This three-dimensional approach to impeller design ensures a comprehensive understanding for Visualization, FEM analysis, or CNC machining. Our CAD data is controlled by a Product Data Management System, which provides full version and access control. This insures that our impeller design documentation meets the quality assurance requirements of the ISO 9001:2000 standard.

Multi-Wing’s Rapid Prototyping Machine produces 3D models from our CAD drawings in ABS plastic. That means Multi-Wing can build a fan prototype for testing and review, leading to a better impeller design in a shorter timeframe. We can also forecast fan blade stress loads and modal frequencies along with stress loads and deformation in hub plates using Finite Element Method Analysis software. The FEM program is vital in our impeller design process because it can predict stress loads on a complete impeller.

Multi-Wing’s wind tunnel is perhaps the most prolific tool for our impeller design process. Built to comply with the AMCA A/ISO 5801 Standard, the wind tunnel uses a dozen recorded measurements to provide a range of performance data. The wind tunnel also has the potential to help Multi-Wing customers improve their applications by examining variables such as airflow or the aerodynamics of their impeller housing. Using a free inlet, free outlet set-up, the wind tunnel produces precise performance data for a comprehensive pressure range for each impeller. When you combine the depth of Multi-Wing’s technical expertise with generations of comprehensive market experience, you get the benefit of the most insightful impeller design process in the air moving industry.
