1, 2, 3, 4 or 5 Blades - What's Better?

A common misconception about ceiling fans is that the more blades it has, the more air it will move. In fact, the amount of air a ceiling fan will move is dependent on a handful of factors, and not solely on the amount of blades it has.

Blade Pitch

Blade Pitch refers to the angle, measured in degrees, at which the blade is set. Also known as blade tilt, the blade pitch plays a big role in determining how much air is circulated by the ceiling fan. If a ceiling fan blade has a greater the degree of angle, this increases the surface area of the blade which in turn will push more air. If the degree of angle is minimial (for example, only 3 or 4 degrees) the leading edge of the blade is what will pass through the air, which instead of pushing the air, will simply cut through it.

Blade Shape

Not all ceiling fans come with timber or metal blades more or less in the shape of a rectangle. These days, with the increase of ceiling fans possessing moulded blades, there is a greater ability to add a level of design in terms of blade shape. For example, take the Sycamore ceiling fan by Iconic Fan Company (pictured); the design for the Sycamore was based on the falling pod from a Sycamore tree. Whilst this fan is praised for its design and energy efficiency, the shape of the blade means that less air will be generated when in operation. The surface area of the blade isn’t as flat or have as great a degree of angle as that of the MAXair Metal ceiling fan (pictured), and while it does move a surprising amount of air, it will be less in comparison to a standard ceiling fan with a greater blade pitch and blade surface.

If a 3 bladed ceiling fan and a 4 bladed ceiling fan were to have the exact same makeup (blade pitch, blade shape and blade material) and were operating at the same speed, then it stands to reason that the 4 bladed ceiling fan would move more air. This is simply due to the fact that the 4 bladed ceiling fan has a great capacity to move more air. However, if the 3 bladed ceiling fan were operating at a higher speed than the 4 bladed ceiling fan, it would indeed then generate more air movement. Think back to the days of airplanes – they only had 2 propellers and yet could generate enough wind to lift into the air. A more powerful motor combined with a high level of speed, can generate a significant amount of air.

If you require a ceiling fan in a large space or on a high raked ceiling, it’s important to take the above factors into consideration. Many ceiling fans on the market today are being produced from an aesthetically-pleasing standpoint and to a very high standard, which is providing consumers with a great choice of modern and contemporary designs without compromising on airflow and efficiency.
