You might be lead to believe that a fan with more number of blades would provide more air.
But, this is far from the truth.
The truth is that the amount of air that a ceiling fan produces is not dependent on one factor, such as the number of blades but several factors. To determine whether a 3-blade or 5-blade ceiling fans are better, these factors have to be considered.
Factors that you should consider
The factors that you should consider while choosing ceiling fans for your home include
This refers to the angle of inclination of the blade, also referred to as blade tilt. This is responsible for ensuring airflow. A strong blade that is flat would not produce airflow even if powerful motor power it. The blade pitch is measured in degrees. A ceiling fan with a bigger degree of angle would push more air. This is owing to the large surface area of the blade. However, when the angle is minimal, the blade would cut through the air instead of pushing it, resulting in poor airflow. Therefore, it is imperative to choose a ceiling fan with the right degree of blade tilt to ensure that the fan moves the right amount of air that is neither too little nor too much.
The shape of the blade
The conventional and standard ceiling fans have conventionally designed blades that are based on aerodynamic design. However, you now have fans with blades that are of different shapes. However, the performance of some of these fans is not compromised in any way. Though modern technology is used to facilitate the performance ceiling fans with differently shaped blades generally move considerably less amount of air when compared to the standard ceiling fans.
A five-bladed ceiling fan would produce more air. But, a three-bladed ceiling fan which is powered by the same motor as that of the five-bladed ceiling fan would run at high speed owing to the lesser number of blades that they feature. The high speed can help produce more air movement.
3-blade vs 5-blade ceiling fans
Whether you go in for a 3-blade ceiling fan or a 5-blade fan is a matter of personal choice. However, as far as design and aesthetic appeal are concerned the 3-blade scores over the 5-blade ceiling fans. But, the wind that is produced by 5-blade ceiling fans is consistent because the blades are placed nearer to each other. However, the five-blade ceiling fans are considered to be designed with an emphasis on the perfect balance between the amount of air circulation that can be achieved without being noisy. The 5 and 4 blade ceiling fans possess an attractive and symmetrical aspect, and when the pitch and the angle of the blade are right, the wind flow would be created. Also, the DC motors that are used to power the blades makes it possible to ensure that the ceiling fans would provide the amount of air that you need irrespective of the number of blades.
