Airscrew + Vmax Vaneaxial Fans General Vaneaxial Information Vmax Vaneaxial Fans comprise a combination of rotating impeller and stationary guide vanes, housed within an axial duct known as the fan case. The function of the guide vanes is to increase the pressure capability of the fan. Higher aerodynamic efficiencies are achieved with true airfoil blade designs. These fans typically operate up to the aerodynamic stall point. The axial configuration allows easy installation into ducted systems, with cooling air passing over the integral motor, allowing compact motor design with high power demand in small packages. The Vaneaxial designs are suitable for operation in severe environments, including sand scavenge applications. Vmax Fans are available in AC or DC supply configuration and can be supplied with thermal protection, speed sensing and customized interfaces. Vmax Fan Vmax Series: imum Performance Curve 6. 4..
