Ceiling Fan Blades


The blades of a ceiling fan make all the difference. The amount of airflow a fan generates depends on the type and size of blades it has. Most ceiling fans have four blades, but they can have as few as three or as many as five. There are several important things that affect the operation, production and lifespan of ceiling fan blades. The length and width of the blades determines how much airflow they can generate. The tilt of the blades also affects the fan's ability to distribute air as well. Another variable in ceiling fan blades is the material used to make them.

Ceiling fans are not measured by the length of the individual blades, but by the total radius of the fan. For example, a 52-inch ceiling fan does not have blades that are 52 inches long, individually. Rather, 52 inches is the total length from the tip of one blade to the tip of the blade opposite it. Ceiling fans usually measure between 30 and 52 inches. Larger fans can generate more airflow, so they are best in big rooms. The width of the blades is also significant. Wide blades can move more air, but they often have greater air resistance and move more slowly than narrow blades.

The blades must be attached to the motor at an angle. Most are attached at an angel between 8- and 15-degrees. The sharper angles produce more airflow at lower speeds. Smaller angles provide less airflow, but they are more energy efficient.

Metal ceiling fan blades can be less expensive than wood blades, but they may not last as long. Wood blades can be treated to withstand corrosion and warping while metal blades can't. Wooden ceiling fan blades also operate more quietly than metal blades.

Ceiling fan blades come in a variety of shapes and colors. Once people know what size they need, they have their choice of which particular design is right for them.
