（1） Rated voltage
The rated voltage of R3G400-AC30-61 centrifugal fan is 230V, which is a common voltage specification that enables it to be widely adapted to various industrial and civilian power systems. Whether it is the electrical network connected to the factory workshop or the standard power supply lines of commercial buildings, stable power supply can be easily achieved without the need for complex voltage conversion devices, greatly improving the universality and installation convenience of equipment. This means that users do not need to worry about power adaptation issues when using the wind turbine, and can deploy and use the equipment more efficiently.
（2） Size specifications
The fan size is 400 millimeters, which brings many advantages to it due to its relatively large size. The larger volume provides more ample space for the impeller and other key components inside the fan, which is conducive to achieving greater air volume and more stable air flow. At the same time, the 400mm size also fully considers the flexibility of installation in the design. It can adapt to the overall layout of some large ventilation systems and can be integrated into relatively compact spaces through reasonable installation methods, meeting the needs of different users for space utilization.
（3） Maximum air volume
The maximum air volume can reach 3975 cubic meters per hour, which makes the R3G400-AC30-61 centrifugal fan excellent in ventilation and air exchange. In large spaces such as warehouses, exhibition halls, etc., air circulation and renewal can be quickly and effectively achieved. A large amount of fresh air can quickly replace indoor polluted air, odors, and harmful gases, creating a healthier and more comfortable environment for people. For some production workshops with high requirements for air quality, such as electronic manufacturing workshops, high air volume fans can timely remove the heat and small particles generated during the production process, ensuring the quality of products and the normal operation of production equipment.
（4） Maximum pressure
The maximum pressure is 420Pa. Although this value is not particularly high compared to some high-pressure fans, it is sufficient for many practical application scenarios. In the ventilation duct system, a pressure of 420Pa can effectively overcome the resistance of the duct and ensure smooth air flow in the duct. It can support ventilation duct layouts of certain length and complexity, allowing fans to transport air over long distances and different locations. For example, in the ventilation system of some commercial buildings, fans need to transport air to various floors and rooms through winding pipes, and the pressure of the fan is sufficient to meet such needs.
（5） Input power
The input power is 380W, combined with its considerable air volume and pressure output, reflecting high energy utilization efficiency. In today's era of advocating energy conservation and emission reduction, lower input power means that less electricity can be consumed during operation, thereby reducing user costs. Compared with some fans with similar performance but high energy consumption, the R3G400-AC30-61 centrifugal fan can save users a lot of electricity expenses during long-term operation, while also meeting environmental requirements, reducing energy waste and environmental impact.
（6） Rotational speed
The speed is 1420rpm, and a relatively moderate speed is one of the key factors for the fan to achieve stable operation and high efficiency performance. A lower rotational speed can reduce the wear and noise generation of the fan, extending its service life. At this speed, the impeller of the fan can push air in a relatively stable manner, ensuring stable output of air volume and pressure. Compared with high-speed fans, lower speeds also reduce the requirements for motors and other components, improving the reliability and stability of the equipment.
（7） Noise level
The noise level is 70dB, which is acceptable in centrifugal fans considering their high air volume characteristics. Moreover, ebm-papst has taken a series of noise reduction measures in the design and manufacturing process, such as optimizing the shape and structure of the impeller, using sound-absorbing materials, etc., to minimize the noise during fan operation. In practical applications, by selecting a reasonable installation location and coordinating sound insulation measures, such as installing the fan in a place far away from personnel rest and work areas, or setting up sound insulation covers around the fan, the impact of noise on the surrounding environment can be further reduced.
（1） Advanced aerodynamic design
The R3G400-AC30-61 centrifugal fan adopts advanced aerodynamic design concepts. The shape of its impeller and the layout of its blades have been carefully optimized to enable air to flow with minimal resistance and in the smoothest way after entering the fan. The backward tilting blade design enables the kinetic energy obtained by the air in the impeller to be more effectively converted into pressure energy, improving the efficiency of the fan. This design not only achieves high air volume and certain pressure output, but also reduces energy loss, making the fan more energy-efficient during operation. Meanwhile, the optimization of aerodynamic design also helps to reduce turbulence and noise generation in the airflow, improving the overall performance and operational stability of the fan.
（2） High quality materials and exquisite craftsmanship
In terms of material selection, all components of the fan are made of high-quality materials. The impeller is made of high-strength and lightweight alloy material, which has good mechanical properties and corrosion resistance. It can withstand the centrifugal force generated during high-speed rotation, reduce the load on the motor, and improve the efficiency of the fan. The motor part adopts high-performance permanent magnets and high-quality copper windings, ensuring the efficient operation and stable performance of the motor. The casing of the fan is made of sturdy and durable steel, and has undergone special surface treatment, which has good impact resistance and protective performance, and can adapt to various harsh working environments.
In terms of manufacturing process, ebm-papst strictly follows high-precision production standards. The manufacturing of the impeller adopts precision casting and processing technology, ensuring the shape and dimensional accuracy of the blades, and improving the balance and stability of the impeller. The assembly process of the motor has undergone strict quality inspection to ensure its performance and reliability. The overall assembly of the fan has also undergone multiple processes of inspection, including performance testing, noise testing, vibration testing, etc., to ensure that each fan can meet high-quality standards.
（3） Intelligent control compatibility (can be assumed based on brand characteristics)
Considering the technological strength and product development trend of ebm-papst, R3G400-AC30-61 centrifugal fan may have good intelligent control compatibility. It can be connected to intelligent control systems to achieve automated operation and regulation. By using sensors to monitor environmental parameters in real-time, such as temperature, humidity, air quality, etc., the intelligent control system can automatically adjust the speed and operating status of the fan based on these parameters. For example, when the ambient temperature is high, automatically increase the fan speed and ventilation volume to achieve better heat dissipation effect; When the air quality is good, reduce the fan speed to save energy. This intelligent control function not only improves the operating efficiency of the fan, but also provides users with a more convenient and comfortable user experience.
（4） Easy to maintain and upkeep design
The structural design of the fan fully considers the convenience of maintenance and upkeep. Its various components adopt modular design, making it easier and faster to replace damaged parts. For example, key components such as impellers and motors can be disassembled and replaced separately without the need for large-scale disassembly and installation of the entire fan. At the same time, the shell design of the fan is easy to open and clean, and users can regularly clean the inside of the fan to remove dust and debris, ensuring the normal operation of the fan. In addition, ebm-papst also provides detailed maintenance manuals and high-quality after-sales service, providing timely solutions for problems encountered by users during maintenance and upkeep.
