Product Features
In order to meet the cooling needs of large equipment and venues, we have launched big circle fans with a size of 254X89mm, which have the characteristics of high efficiency and low power consumption, providing you with strong wind support.
This fan has a variety of voltages to choose from: 48V, 24V, 12V, suitable for different power systems. The maximum speed can reach 4000rpm, and the maximum air volume can reach 1296cfm, which can quickly and effectively discharge the heat in the equipment to ensure the stable operation of the equipment. At the same time, advanced motor design and manufacturing technology is adopted to ensure the high efficiency, low power consumption, energy saving and environmental protection of the fan.
The fan uses high-quality bearings and fan blades, which have low operating noise, low vibration, and long service life, ensuring the stability and reliability of the fan. After rigorous testing and inspection, the fan has stable performance and can meet various application requirements.
The outer frame is made of aluminum alloy and painted black, and the fan blades are made of high-temperature resistant PBT to ensure the stability and balance of the fan during high-speed operation. The coil is made of pure copper, which reduces the operating temperature and current of the fan, making it more energy-saving and environmentally friendly, with high performance and long use time.
This kind of big circle fans are widely used in refrigeration equipment such as condensers and evaporators, as well as ground automatic control devices, large electronic equipment, medical equipment and other occasions that require large air volumes. At the same time, it can also be used for ventilation and cooling of computers, office supplies automation, electric welding machines, etc., as well as ventilation, ventilation, purification and other needs of buildings and factories.

Comparison of Advantages and Disadvantages Between Round Fans and Square Fans
In cooling solutions, round fans and square fans are two widely used core products. Due to structural differences, they each have advantages and disadvantages in terms of performance, installation adaptability, and application scenarios. The following is a detailed comparative analysis to help you accurately select the right type based on actual needs:
1. Advantages and Disadvantages of Round Fans
Advantages:
Higher Airflow Efficiency: When the blades of a round fan rotate, the airflow is axially symmetrically distributed, resulting in lower wind resistance. Under the same power, it can generate greater air volume and air pressure, with better airflow transmission efficiency, making it suitable for scenarios requiring high cooling efficiency.
Better Noise Control: The symmetrical airflow distribution can reduce airflow turbulence, resulting in lower aerodynamic noise during operation. It can create a quieter environment for equipment operation, especially suitable for noise-sensitive scenarios such as precision electronic equipment and medical instruments.
Strong Structural Stability: The stress on the round fan blades is more uniform, leading to less wear during long-term high-speed operation and a relatively longer service life. Combined with high-quality accessories such as ball bearings, the stability advantage is more prominent.
Cost Advantage: The mold design and production process of round fans are relatively simple, and the cost is lower during mass production, which can provide customers with cost-effective cooling options.
Low Installation Space Utilization: The round structure has poor adaptability to the common square equipment casings and heat dissipation air ducts. Gaps are likely to occur during installation, wasting part of the installation space, so it is not suitable for the interior of equipment with compact space.
Limited Airflow Coverage: The diffusion range of round airflow is annular, which cannot cover the square heat dissipation surface evenly. This may lead to local overheating of the heat dissipation surface and affect the overall heat dissipation effect.
2. Advantages and Disadvantages of Square Fans
Advantages:
Disadvantages:
Strong Installation Adaptability: The square structure is fully compatible with the square casings and heat dissipation air ducts of most industrial equipment and electronic equipment. There is no gap during installation, and the space utilization rate is extremely high, making it an ideal choice for compact space scenarios.
More Uniform Airflow Coverage: The air outlet surface of the square fan is rectangular, which can be accurately matched with square heat sinks and heat dissipation air ducts. The airflow can evenly cover the entire heat dissipation surface, avoiding local heat dissipation dead angles and improving the overall heat dissipation stability.
Flexible Combination Use: The regular shape of square fans allows easy side-by-side or stacked combination of multiple units to form a cooling system with larger air volume, suitable for cooling needs of large-scale equipment or high-heat scenarios.
Disadvantages:
Slightly Lower Airflow Efficiency: The square structure will cause a certain degree of eddy current and resistance at the corners. Under the same power, the air volume and air pressure are slightly lower than those of round fans, and the airflow transmission efficiency is slightly inferior.
Relatively Higher Operating Noise: Airflow turbulence will increase aerodynamic noise. Especially during high-speed operation, the noise is slightly higher than that of round fans of the same specification, so it is necessary to select the type reasonably according to noise reduction needs.
Higher Production Cost: The mold manufacturing and production process of square fans are more complex, requiring higher production precision. Therefore, the mass production cost is higher than that of round fans, and the cost performance is not advantageous in low-power scenarios.
Selection Suggestions: If your equipment has sufficient space and you prioritize high cooling efficiency and low noise, you can choose a round fan; if your equipment has compact space, needs to evenly cover a square heat dissipation surface, or requires combined use of fans, a square fan is more suitable. Our customized services can recommend or customize the optimal specifications of round or square cooling fans according to your specific installation environment and heat dissipation needs.
