K3G250-AV29-B2 ebm-papst

• Interpretation of key parameters

（1） Rated voltage

The rated voltage of K3G250-AV29-B2 centrifugal fan is 230V, which is a common voltage specification in both industrial and civilian fields. This means that the wind turbine can easily adapt to most existing power systems, whether it is connected to the production line power supply of factories or the conventional circuits of commercial buildings, without the need for additional complex voltage conversion equipment, greatly simplifying the installation and use process, while also improving the stability and reliability of wind turbine operation.

（2） Size specifications

The size of the fan is 250 millimeters, which is a medium to large type among centrifugal fans. The size of 250 millimeters gives it a larger impeller and ventilation space, providing a physical basis for achieving high air volume and high pressure. At the same time, although the size is relatively large, the design still considers the convenience of installation and can adapt to places with certain space requirements but strong ventilation capabilities, such as large control cabinets, key nodes of ventilation ducts, etc.

（3） Maximum air volume

The maximum air volume can reach 3120 cubic meters per hour, which is a considerable value. Such a large air volume enables the K3G250-AV29-B2 centrifugal fan to achieve a large amount of air circulation and exchange in a short period of time. In large industrial workshops, it can quickly exhaust the polluted air inside the workshop, introduce fresh air, improve the air quality of the workshop, and create a healthier working environment for workers. In the data center, it is possible to quickly remove the large amount of heat generated by servers and other equipment, ensuring that the equipment operates stably at a suitable temperature.

（4） Maximum pressure

The maximum pressure is 1050Pa, which is a major highlight of this fan. High pressure means that the fan has a stronger ability to overcome ventilation resistance. In ventilation systems, there may be longer ventilation ducts, multiple bends, air filters, and other components that increase the resistance to air flow. The maximum pressure of 1050Pa of K3G250-AV29-B2 centrifugal fan can easily cope with these resistances, ensuring that air can still flow smoothly in complex ventilation environments, maintaining stable ventilation effects, and meeting various scenarios with high requirements for ventilation pressure.

（5） Input power

The input power is 750W, combined with its high air volume and high pressure performance, this power level is reasonable and efficient. Although the power of 750W is relatively high, considering its strong ventilation capacity and in some scenarios that require long-term continuous operation, its energy utilization efficiency is actually quite excellent. Compared with some fans with similar performance but lower efficiency, K3G250-AV29-B2 centrifugal fan can achieve greater ventilation and higher pressure per unit power, which may actually reduce overall energy costs from a long-term operating perspective.

（6） Rotational speed

The rotational speed is 3450rpm, and a higher rotational speed is one of the important factors for achieving high air volume and high pressure. The speed of 3450rpm enables the impeller of the fan to rotate rapidly, accelerating the flow of air and generating sufficient kinetic energy to achieve a high air volume of 3120 cubic meters per hour and a high pressure of 1050Pa. At the same time, this speed has been carefully designed and optimized, effectively controlling the generation of noise and vibration while ensuring the performance of the fan, ensuring that the fan can still maintain a stable and reliable operating state at high speeds.

（7） Noise situation

The noise level is 63dB, which is acceptable in the field of centrifugal fans, especially for high air volume and high pressure fans. Moreover, ebm papst has adopted a series of noise reduction measures in the design and manufacturing process, such as optimizing the impeller shape, improving the motor structure, and adding sound insulation materials, to minimize the noise during fan operation. In practical applications, through reasonable installation and layout, such as installing fans in areas far away from personnel and using soundproof covers, the impact of noise on the surrounding environment can be further reduced.

• Analysis of prominent characteristics

（1） Advanced aerodynamic design

The K3G250-AV29-B2 centrifugal fan adopts advanced aerodynamic design concepts. The shape of its impeller, the angle and number of blades have been accurately calculated and optimized to achieve the best air flow effect. The backward curved blade design allows air to flow more smoothly along the blade surface after entering the impeller, reducing airflow separation and turbulence, and improving the efficiency of air kinetic energy conversion. This design not only enables the fan to achieve high air volume and high pressure output, but also reduces energy loss and improves the overall efficiency of the fan. Meanwhile, the optimization of aerodynamic design also helps to reduce noise generation, allowing the fan to operate efficiently while maintaining a relatively low noise level.

（2） High quality materials and exquisite craftsmanship

In terms of material selection, high-quality materials are used for all components of K3G250-AV29-B2 centrifugal fan. The impeller is made of high-strength alloy material, which has good strength and toughness, and can withstand the huge centrifugal force generated during high-speed rotation. At the same time, it has a lighter weight, reducing the load on the motor and improving the overall efficiency of the fan. The motor part adopts high-quality copper windings and high-performance permanent magnets, 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 corrosion 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 also undergone strict quality control to ensure its performance and reliability. The overall assembly of the fan has undergone multiple rigorous testing processes, including performance testing, noise testing, vibration testing, etc., to ensure that each fan can meet high-quality standards.

（3） Intelligent control and monitoring functions (can be assumed based on actual situations or combined with brand characteristics)

Although not explicitly mentioned in the parameters, considering the brand characteristics of ebm papst, the K3G250-AV29-B2 centrifugal fan may be equipped with intelligent control and monitoring functions. Through built-in sensors, the fan can monitor its operating status in real-time, such as speed, temperature, pressure, and other parameters. Based on the changes in these parameters, the intelligent control system can automatically adjust the operating status of the fan, such as reducing the speed when ventilation demand is low to save energy; Increase the speed when ventilation demand increases to ensure sufficient ventilation volume. This intelligent control and monitoring function not only improves the operating efficiency of the fan, but also enables timely detection of potential faults and hidden dangers, taking measures in advance for repair and maintenance, and extending the service life of the fan.

（4） Convenient installation and maintenance design

The structural design of K3G250-AV29-B2 centrifugal fan is simple and reasonable, easy to install and maintain. It is equipped with standard installation interfaces and fixing devices, and users can choose the appropriate installation method according to their actual needs, such as horizontal installation, vertical installation, etc. In terms of maintenance, the various components of the fan adopt modular design, making it more convenient and efficient 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 design of the fan casing also takes into account the convenience of maintenance, making it easy for users to carry out daily cleaning and inspection work. In addition, ebm papst also provides comprehensive after-sales service, providing timely solutions for problems encountered by users during use.
