AERODYNAMIC DESIGN: Encased within its protective mesh casing are 5 fantastically aerodynamic blades which capture more air in a single turn than standard 4-blade fans, enabling it to generate more cool air than ever before. Perfect for the hot summer months, you'll appreciate a fan that moves the air quicker with less noise and effort. The fan stands sturdily on it's weighted round base ensuring it will stay upright and will not tip over.
