Multi-Wing Impellers - State of the Art Fan

Fan Blade Materials

Through high-quality materials, we provide you with the best impeller. This is part of our commitment to being at the leading edge of impeller technology.

Multi-Wing blades are available in six different materials as listed below. PPG, PAG, PAGI, PAGAS, PAGST and AL. The materials suit applications with different working conditions, speeds and temperatures. Multi-Wing hub parts are as standard manufactured in a pressure die cast silumin alloy (Al Si12 Cu). Certain hub parts, Z-hub/5, H-hub/6, H-hub/8 and W-hub/3, are also available in glass reinforced polypropylene (PPG). Don’t hesitate to contact Multi-Wing’s experts if you have any questions concerning which material to choose for your specific application. NOTE: The values for the mechanical properties are mean values and can be subject to variations due to the use of different suppliers.
