Abstract
A width extender is used to modify existing fan blades in order to enable them to rotate at slower speed thereby reducing the noise associated with them while at the same time maintaining a proper work efficiency. The width extender is fixably connected along the trailing edge of an existing fan blade by adhesive bonding, riveting, welding, or otherwise. Width extender can be made of an extruded plastic material, preferably nylon, or it can be constructed of the same material as the fan blade itself. Ideally, the width extender would increase the width of the fan blade by 20% to 25%. Additionally, this width extender would have a uniform length so as to uniformly increase the entire width of the fan blade.
