This fan embodies years of research and development experience and innovative achievements of ebm-papst, aiming to provide users with efficient, stable, and energy-saving ventilation solutions.
（1） Part number
The unique part number R3G310-AN43-71 is the identification of this fan and contains rich product information. Through this number, users can quickly and accurately query the specific specifications, technical parameters, and related accessory information of the fan, facilitating precise matching in the selection, procurement, and maintenance processes.
（2） Fan type
This fan belongs to the centrifugal fan category. The working principle of a centrifugal fan is to use the high-speed rotation of the impeller to move air from the center to the edge of the impeller under the action of centrifugal force, thereby achieving air transportation and pressurization. This working method gives centrifugal fans unique advantages in providing high pressure and large air volume, making them suitable for occasions with high ventilation requirements.
（3） Rated voltage
The rated voltage of R3G310-AN43-71 centrifugal fan is 230V, which is a common standard voltage for industrial and commercial use. The stable 230V voltage input ensures the stable operation of the fan motor, providing continuous and reliable power support for the fan. At the same time, this standard voltage design also enables wind turbines to be easily connected to various power systems without the need for additional voltage conversion equipment, improving the versatility and ease of use of the equipment.
（4） Size
The size of the fan is 310 millimeters, and a relatively large size means it has greater air handling capacity. The larger impeller diameter and structural design enable the fan to generate greater air volume and pressure at the same speed, making it suitable for large equipment or places that require high ventilation volume and pressure.
（5） Maximum air volume
The maximum air volume can reach 2870m ³/h, which indicates that the fan has strong air conveying capacity. It can quickly and effectively transport a large amount of air per unit time, meeting the ventilation and air exchange requirements of large spaces or high ventilation equipment. For example, in large industrial plants, commercial buildings' courtyards, or large data centers, R3G310-AN43-71 centrifugal fans can quickly exhaust polluted air and introduce fresh air to ensure indoor air quality.
（6） Maximum pressure
The maximum pressure is 600Pa, which enables the fan to overcome certain ventilation resistance. In ventilation systems, factors such as pipe length, number of bends, and air filters can increase the resistance to air flow. The high pressure characteristics of R3G310-AN43-71 make it easy to cope with these resistances, ensuring that air can flow smoothly in ventilation ducts and achieve efficient ventilation effects.
（7） Input power
The input power is 470W, and while providing high air volume and pressure, the power consumption of the fan is relatively low. This is thanks to the advanced design concept and manufacturing process of ebm-papst, which improves the energy conversion efficiency of the fan, reduces energy consumption, and saves operating costs for users by optimizing the impeller structure and adopting efficient motors.
（8） Rotational speed
The speed is 2560rpm, and a higher speed is one of the key factors for the fan to achieve high air volume and high pressure. The rapidly rotating impeller can generate strong centrifugal force, quickly throwing air out, thereby achieving efficient air transportation. Meanwhile, a reasonable speed design also helps to control the noise level of the fan, ensuring that the fan operates efficiently without generating excessive noise interference.
（9） Noise
Although the noise label in the parameters is not applicable, in practical applications, ebm-papst effectively reduces the noise during fan operation through advanced design and manufacturing processes. The optimized impeller shape, high-quality materials, and precise manufacturing process reduce turbulence and vibration during air flow, making the fan relatively quiet during operation and suitable for noise sensitive environments.
（1） Efficient ventilation performance
The R3G310-AN43-71 centrifugal fan exhibits excellent ventilation performance with a maximum air volume of 2870m ³/h and a maximum pressure of 600Pa. Whether it is ventilation and air exchange in industrial production, air conditioning in commercial buildings, or heat dissipation and ventilation in data centers, this fan can quickly and effectively meet ventilation needs, ensuring ideal indoor air quality.
（2） Energy saving and efficient
Despite having strong ventilation capabilities, the input power of this fan is only 470W, demonstrating excellent energy-saving performance. By optimizing the aerodynamic design of the impeller, ebm-papst reduces the resistance of air flow and improves the efficiency of the fan. At the same time, the use of efficient motors and advanced control technology further reduces the energy consumption of the fan, achieving the goal of high efficiency and energy conservation, which is in line with the current development trend of energy conservation and emission reduction.
（3） Durable and sturdy structure
Using high-quality materials and sturdy structural design, the R3G310-AN43-71 centrifugal fan has excellent durability. Its shell can effectively resist external impact and corrosion, and key components such as impellers and motors inside have undergone strict testing and screening, with good high temperature resistance, moisture resistance, and wear resistance. This enables the fan to operate stably under harsh environmental conditions, extending its service life.
（4） Easy installation
The design of this fan fully considers the convenience of installation. It has a compact structure, standard installation dimensions, and is equipped with detailed installation instructions and necessary installation accessories. Users can easily install the fan into the ventilation system according to the instructions in the manual, greatly saving installation time and costs. At the same time, the modular design of the fan also facilitates later maintenance and repair.
（5） Strong adaptability
The R3G310-AN43-71 centrifugal fan can adapt to different working environments and ventilation requirements. Whether in high temperature and high humidity environments, or in systems with complex ventilation ducts and high resistance, this fan can maintain stable performance and provide users with reliable ventilation solutions.
