Fans come in different types of blades based on a country’s standard. Even though the three-blade fans are widely used in some country such as the US use the four-blade fans. Blades are the most important part of any ceiling or pedestal fan. Behind each fan blades, there is a unique air circulating technology. If you are wondering why US fans have 4 blades then here are the main reasons for it.
Why is the number of blades important?
The efficiency of a ceiling fan majorly depends on the blades. A fan that has longer blade will help in good air circulation than the fans with smaller blades. Also, a fan with four blades may not be greater than three-blade fans, but they can help in good air circulation. Also, the drag technology in the fan blades determines its energy consumption and efficiency. If a four-blade fan has a quality motor, then it can perform and create more ventilation than a three-bladed fan. A powerful motor is required for the blades to function properly. However, the four-blade fans do not have quality motor because they are designed only to provide a decent amount of air circulation.
The reasons for using four-blade fans
Fans used only for additional ventilation. The US and other western countries are colder even in summers. Most of the household have air conditioners, and they use fans only for additional ventilation. The fan is only used to circulate the cool air coming from the air conditioner. So, the four blades fans do not offer strong airflow, but they help in circulating the air. In other countries such as India, many use the three-bladed fans because most of the households do not have air conditioners. Many rely on the fans for ventilation, and these fans supply air in every corner of the room.
- Four blade fans for efficiency
The number of blades in a fan decides the efficiency and speed of it. If a fan has more number of blades, then it can chop more amount of air in the room. However, the three-blade fans provide a more balanced and consistent amount of air in tropical and extreme summer conditions. Since the blades are lesser, the three-blade fan can offer high speed and efficiency. A four-blade fan creates more aerodynamic force and cost-efficient in the US. But, in countries such as India, the four-blade fans are available in economical rates.
- For multipurpose use
In western countries, ceiling fans are not only used for circulating cool air but also for circulating the warm air from the heater. In winter, the four-blade fans can be the perfect choice to keep the room warm. For both the summer and winter they use these fans by flipping the switch to suit both these weather conditions.
- The comfort behind using four bald fans
In the US, the four-blade fans come along with the lighting fixture. Also, these four-blade fans only have three-speed setting. This means that the westerners choose low-speed fans for comfort. Also, they allow the lights to take up more energy than the fans because the good lightning system provides them with more comfort.
