Doubts Cleared! How Many Blades Does a Big Fan Have and How Do They Differ?

Doubts Cleared! How Many Blades Does a Big Fan Have and How Do They Differ?

For those researching information about "Big Fans" because they are interested in installing them in large spaces, both indoor and outdoor buildings, it's essential to understand the working characteristics of these fans. However, one might wonder about the importance of the number of fan blades.

Today, Yushi Group will introduce you to the various components of Big Fans that make them stronger than regular fans and how the number of blades affects their performance.

Components of Big Fans:

• Ceiling Fan Mounting Shaft: The mounting shaft is usually made of durable steel to withstand heat under the roof and is designed with a stable base to securely attach the fan to the ceiling.
• Motor: The motor is like the heart of the fan. When activated, electricity flows through the motor, causing the fan blades to rotate. Some models use dual motors with gears, while others do not require gears.
• Fan Frame: The frame uses strong and flexible materials to protect the motor and other components from damage.
• Fan Blades: The blades of Big Fans are typically cast in one piece, attached individually to the fan body for strength and user safety.
• Control Cabinet: This part controls the fan's operation, including the brake, on-off switch, fan speed adjustment button, display screen, and emergency stop.

How Many Types of Big Fans Are There?

When comparing Big Fans, some differences in design and the number of fan blades can be observed, depending on the motor's operation. There are two main types:

• AC Big Fans: These fans have a larger motor size due to their gear-operated motor, resulting in more equipment parts and increased weight compared to DC motors.
• DC Big Fans: These fans have smaller motors, but they can generate better blade rotation force, saving energy and reducing noise.

How Do the Number of Fan Blades Differ?

How Do the Number of Fan Blades Differ?

Comparing Two Models of Big Fans from Yushi:

AC Big Fan: This model has the same motor power of 2 HP/1.5 kW, but the number and size of fan blades differ.

• Fan blades with a length of 7,200 mm, 5 blades, providing an airflow rate of 13,500 CFM (cubic feet per minute).
• Fan blades with a length of 7,310 mm, 8 blades, providing an airflow rate of 14,000 CFM.

Big Ceiling DC Fan: This model has the same number of blades, 5 blades, but the size of the fan blades and motor power differ.

• Fan blades with a length of 5,500 mm, using 850 watts of power, providing an airflow rate of 10,000 CFM.
• Fan blades with a length of 6,500 mm, using 1,150 watts of power, providing an airflow rate of 14,800 CFM.
• The longest fan blades of the DC Fan, with a length of 7,300 mm, using 1,280 watts of power, providing an airflow rate of 17,500 CFM.

If you observe AC Big Fans, you'll notice that while the motor power remains the same, the number of fan blades differs, leading to a noticeable increase in airflow rate. This might lead some to believe that more blades are necessary to generate stronger airflow. However, increasing the number of blades can create more turbulent energy, so higher power usage is unnecessary.

Regarding DC Big Fans, even though the number of blades remains the same, motor power increases with blade size, resulting in higher airflow rates. Therefore, having multiple fan blades does not necessarily mean consistently higher airflow.

In summary, does the number of fan blades affect the airflow?

The fact that the number of fan blades is not the same does indeed contribute to the airflow, but it's not a definitive answer that more blades equate to stronger airflow. This is because there are other components that contribute to increasing the airflow rate. For example, the Big Ceiling DC Fan, despite having only 5 blades, can achieve a maximum airflow rate of 17,500 CFM because of the higher wattage of the motor.

For those interested in Yushi's big fans and seeking further information, Yushi Group has a team ready to provide free consultation. If you need on-site evaluation for fan installation, we can arrange that as well. Our goal is to provide you with the most suitable big fan solution for your needs.

Fans that meet quality standards must come from Yushi Group. Yushi Group engages in the distribution, design, and installation of various air ventilation products, including industrial fans, mist fans, and many others, to facilitate convenient air circulation, reduce accumulated heat, eliminate unwanted odors, and ensure safety measures during fan installation for the users' safety.

• Safety guard plates help prevent Yushi's big fans from falling down. They are attached using the same nuts but can be separate parts.

• The ring spreader plate helps balance Yushi's big fans to prevent severe vibrations that could cause the fan blades to detach.

• Safety cables can support weights of up to 1 ton. These cables are installed at all four points to prevent the fan from falling due to severe vibrations or errors in the fan shaft mounting.

• Industrial-grade nuts are used, capable of holding up to 10 times the weight and are coated with anti-corrosion solution to enhance effectiveness.

For those interested in quickly cooling indoor spaces, pairing fans with Evaporative Coolers can effectively reduce heat accumulation, promote air circulation, and provide cooling coverage for areas up to 1,600 square meters. This setup helps save energy and comes with comprehensive after-sales service, providing spare parts to ensure uninterrupted fan operation.
