Ceiling fans are one of the most common appliances in Indian homes, so much so that we take them for granted as we enjoy the cool and soothing breeze on a hot, sunny day. However, how many of you knew that picking the right ceiling fan involves picking the right number of blades in your fan? Here’s all you need to know about the difference between 3-blade and 4-blade ceiling fans.
It is often assumed that the role of the ceiling fan blades is restricted to the aesthetic appeal of the fan; however, this is not true. The ceiling fan blades run with the help of a motor and play an important role in generating air in the space. The size of the blade and the number of blades in the ceiling fan will help you determine the performance of the fan.
One of the most important factors of concern is the debate of 3-blade vs 4-blade ceiling fan and which one is the best pick for your home. Consider this article a 4-blade vs 3-blade fan guide that will precisely help you understand the difference between the two and help you make the right choice.
A 3-blade ceiling fan is most commonly used in an Indian household. Let’s take a look at some of its advantages and disadvantages.
Advantages
One of the major differences to point out in this
3-blade fan vs 4-blade fan
is the weight. 3-blade ceiling fans are generally lighter in weight and require less force for rotation.
Less resistance on the motor allows the blades to rotate at a higher speed, hence providing rapid air circulation.
When talking about a
3-blade fan vs 4-blade fan
, the overall cost cannot be overlooked. It is quite obvious that 3-blade fans are relatively cheaper in comparison to 4-blade fans.
3-blade ceiling fans consume much less electricity than 4-blade ones, saving you a good amount on the running costs of your monthly energy consumption bill.
Disadvantages
The lightweight design allows the fan to rotate at a higher speed, which then increases the pressure and results in a loud noise.
A 3-bladed fan provides less air delivery because of the lower number of blades.
In countries with cooler temperatures, a 4-blade ceiling fan is most commonly used. Let’s take a look at some of its advantages and disadvantages.
Advantages
Its heavyweight and air resistance aid in making the movement much slower but more consistent. This eventually results in low noise.
When paired with an air conditioner, a 4-bladed fan will circulate cool air in the space without making any disturbing noise.
Disadvantages
4-blade ceiling fans are costlier than 3-blade ceiling fans.
The heavyweight along with the resistance on the motor demands more power to rotate the blades. This means it takes up more energy, resulting in an increased monthly electricity bill.
According to the law of physics, increasing the number of blades will enhance the airflow, but in such cases, the opposing air resistance is frequently overlooked.
In simple terms, a 3-bladed fan will provide low air delivery because of the lesser number of blades, but at a high speed because of the lower aerodynamic resistance. Investing in a 3-blade fan is an ideal option because the motor load in this case is manageable and you won’t have to worry about unwanted noises. These are great picks for an Indian household, as the requirement for high-speed fans is greater.
A 4-bladed fan, on the other hand, will provide higher air delivery due to a greater number of blades but at a lower speed due to the aerodynamic drag. 4-blade fans may also increase the motor load. Such fans are ideal options for colder countries where fans are not required to run at higher speeds. It is important to make an informed decision before purchasing a ceiling fan.
