Tech Tips: Ceiling fan becomes a necessity in every house during the summer season. But when it comes to buying a new fan, one question often confuses people, which fan with 3, 4 or 5 blades provides the most air? Also, which fan consumes less power? Let us understand this entire truth in simple language.
3 blade fan technology
The most commonly used fans in India are those with 3 blades. The biggest reason for this is their ability to generate strong wind. Actually, due to having fewer blades, they have to use less power and they accelerate more quickly with less power, due to which people feel more strong wind. That is why due to less blades, the load on the fan is less due to which the motor can work easily. This is why 3 blade fans provide more airflow and make the room feel cool quickly. Besides, these fans are also considered better in terms of power consumption. Due to less blades, there is less pressure on the motor and electricity is saved.
4 blade fan
4 blade fans run at a slightly lower speed than 3 blade fans but their air flow is smoother. These fans are especially good for people who like low noise and stable air. However, their power consumption may be slightly higher than 3 blade fans because the extra blades put a little more pressure on the motor.
5 blade fan
Fans with 5 blades are generally preferred in terms of design and decoration. These fans are attractive in appearance and spread air more evenly but their speed is the lowest. Due to more blades, there is more load on the motor due to which the fan is not able to rotate fast. This is the reason why the strength of the air coming from them is less. Also, their power consumption may also be slightly higher.
Who saves more electricity?
If we talk about saving electricity, a 3 blade fan proves to be the most economical. Its design is such that more air is produced with less energy. Whereas in fans with 4 and 5 blades, the motor has to work harder, which can increase power consumption.
