- Detailed parameter interpretation
（1） Part number
The specific part number R3G225-RE07-03 is the identification of this fan. It not only facilitates production management and inventory control, but also provides accurate basis for users to query product information, obtain technical support, and order accessories. Through this number, users can quickly locate the detailed information of the fan, ensuring the purchase of products that meet their needs.
（2） Fan type
This fan belongs to the centrifugal fan type. The working principle of a centrifugal fan relies on the input mechanical energy to increase gas pressure and deliver gas. Unlike axial fans, centrifugal fans have a gas flow direction perpendicular to the fan shaft. Through the high-speed rotation of the impeller, the gas obtains energy 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 situations with high requirements for pressure and air volume.
（3） Rated voltage
The rated voltage of the fan is 230V, which is a common standard voltage for industrial and commercial electricity. When in use, it is necessary to ensure that the power supply voltage is stable at around 230V to ensure the normal operation of the fan. Excessive voltage may cause the motor to overheat and damage electronic components; If the voltage is too low, the speed of the fan will decrease, and the air volume and pressure will decrease, which cannot meet the actual needs. Therefore, before installing and using the fan, the voltage stability of the power system should be checked, and necessary measures should be taken to adjust and protect it.
（4） Size
The size of the fan is 225 millimeters, which determines the installation space and applicable range of the fan. The smaller size makes the fan more flexible and adaptable, and it can be installed in places with limited space. Meanwhile, compact design is also beneficial in reducing the footprint of the fan during operation and improving space utilization. In practical applications, users need to choose the appropriate installation location and method for fans based on the size and layout of the installation environment.
（5） Maximum air volume
The maximum air volume of this fan can reach 1300m ³/h. Airflow is one of the important indicators for measuring the ventilation capacity of a fan, which represents the volume of air passing through the fan per unit time. A larger air volume means that the fan can quickly and effectively transport a large amount of air, suitable for situations that require rapid ventilation or air circulation, such as industrial workshops, commercial places, ventilation duct systems, etc. When choosing a fan, users need to determine the model and specifications of the fan based on the actual required ventilation volume to ensure that the ventilation requirements are met.
（6） Maximum pressure
The maximum pressure of the fan is 550Pa. Pressure refers to the ability of a fan to overcome system resistance and deliver air to a designated location. The higher pressure allows the fan to operate normally in longer pipelines or systems with greater resistance. In some ventilation systems, certain resistance may be generated due to factors such as pipe length, number of bends, and filter resistance. At this point, the fan needs to provide sufficient pressure to overcome these resistances and ensure smooth air circulation. Therefore, when designing and selecting ventilation systems, it is necessary to consider the resistance characteristics of the system and choose fans with appropriate pressure.
（7） Input power
The input power is 170W, which reflects the electricity consumed by the wind turbine during operation. On the premise of ensuring the performance of the fan, lower input power means higher energy efficiency. The ebm-papst R3G225-RE07-03 centrifugal fan is designed with a focus on energy conservation. By optimizing the impeller design and adopting high-efficiency motors, the energy consumption of the fan has been reduced, saving users operating costs. Meanwhile, lower energy consumption also meets the requirements of modern society for energy conservation and environmental protection.
（8） Rotational speed
The speed of the fan is 3030rpm. Speed is one of the important factors affecting the air volume, pressure, and noise of a fan. Higher rotational speeds typically provide greater airflow and pressure, but can also lead to increased noise. The fan was designed with optimized impeller structure and advanced noise reduction technology, effectively controlling the noise level while ensuring high-speed operation. Reasonable speed design enables the fan to achieve a good balance between performance and noise.
（9） Noise
The noise level is 54dB, and the relatively low noise level ensures that the fan does not cause significant interference to the surrounding environment during operation. In some places with high noise requirements, such as offices, hospitals, schools, etc., low-noise fans are particularly important. ebm-papst reduces the vibration and noise of the fan during operation by adopting advanced aerodynamic design, high-quality materials, and precise manufacturing processes, providing users with a quiet working and living environment.
（1） Efficient and energy-saving
As mentioned earlier, the fan adopts advanced energy-saving technology. The impeller is carefully designed with a high efficiency coefficient, which can effectively convert the input electrical energy into kinetic energy of air, thereby improving the energy utilization efficiency of the fan. Meanwhile, the high-efficiency motor equipped on the fan has the characteristics of low loss and high power factor, further reducing energy consumption. Compared with traditional fans, the ebm-papst R3G225-RE07-03 centrifugal fan can save more electricity under the same air volume and pressure conditions, bringing significant economic benefits to users.
（2） Stable performance
