（1） Rated voltage
The rated voltage of K3G280- AU11- C2 centrifugal fan is 400V. In industrial environments, a voltage of 400V is a common industrial electricity standard. This voltage setting enables the fan to adapt to most industrial power supply systems, providing a solid power foundation for its stable operation. Compared to some low-voltage fans, a rated voltage of 400V can provide fans with stronger power, thereby better meeting the needs of industrial ventilation.
（2） Size specifications
The size of the fan is 280 millimeters, which gives it a significant advantage in installation space due to its relatively compact design. In some places with limited space, such as small factory workshops, compact commercial buildings, etc., the K3G280-AU11-C2 centrifugal fan can be easily installed without occupying too much space resources. Meanwhile, a smaller size does not necessarily mean a decrease in its ventilation performance, it can still achieve excellent ventilation effects in limited spaces.
（3） Maximum air volume
The maximum air volume can reach 3935 cubic meters per hour. This data indicates that the fan has strong air transport capacity. In scenarios that require rapid ventilation, such as industrial workshops where odors or harmful gases are generated, the K3G280-AU11-C2 centrifugal fan can quickly remove a large amount of polluted air from the outside and introduce fresh air, effectively improving indoor air quality and ensuring the health of workers and the safety of the production environment.
（4） Maximum pressure
The maximum pressure is 1030 Pa. Higher pressure means that the fan can overcome greater ventilation resistance. In ventilation systems, there may be long ventilation ducts, multiple bends, or the installation of air filtration equipment, which can increase the resistance of ventilation. The high pressure characteristics of the K3G280-AU11-C2 centrifugal fan ensure that air can still circulate smoothly in such a complex ventilation system, ensuring the stability of the ventilation effect.
（5） Input power
The input power is 1000W. Considering its air volume and pressure performance, such power consumption is quite reasonable. While ensuring efficient ventilation, it will not cause excessive energy waste. Compared with some similar fans, K3G280-AU11-C2 centrifugal fan has certain advantages in energy utilization efficiency, which can save users some operating costs.
（6） Rotational speed
The rotational speed is 3100rpm. A higher rotational speed is one of the important factors for fans to generate large air volume and high pressure. However, high speeds may also bring some problems, such as noise and vibration. However, when designing this fan, ebm-papst effectively reduced the noise and vibration caused by high speed by optimizing the structure of the impeller and motor, ensuring the stability and reliability of the fan during high-speed operation.
（7） Noise level
The noise level is 68dB. In industrial equipment, such noise levels are relatively low. For some noise sensitive places, such as industrial workshops near office areas, ventilation systems in commercial buildings, etc., lower noise can reduce interference with the surrounding environment and personnel. ebm-papst adopts advanced noise reduction technology, such as adding sound-absorbing materials inside the fan casing, optimizing the shape of the impeller to reduce airflow impact, etc., so that the K3G280-AU11-C2 centrifugal fan can maintain relative quietness during operation.
（1） Efficient Aerodynamic Design
The K3G280-AU11-C2 centrifugal fan is designed using advanced aerodynamic principles. The shape of its impeller and the angle of its blades have been carefully optimized, allowing air to form a smooth streamlined flow when entering and exiting the fan, reducing the loss of airflow and the generation of turbulence. This design not only improves the ventilation efficiency of the fan, but also reduces energy consumption, achieving a perfect combination of energy conservation and efficiency. For example, under the same power input, the fan can deliver more air, improving the overall performance of the ventilation system.
（2） High quality materials and exquisite craftsmanship
All components of the fan are made of high-quality materials. The impeller is made of high-strength aluminum alloy material, which has good corrosion resistance and wear resistance, and can withstand the huge centrifugal force generated during high-speed rotation, ensuring the long-term stable operation of the fan. The casing is made of sturdy and durable steel, which has undergone precise processing and welding processes to ensure the overall structural strength and sealing of the fan. The exquisite manufacturing process ensures the precision of the fit between various components, reduces air leakage and energy loss caused by excessive clearance between components, and improves the performance and reliability of the fan.
（3） Intelligent control compatibility
K3G280-AU11-C2 centrifugal fan has good intelligent control compatibility. It can be integrated with various intelligent control systems to achieve remote monitoring and automated control. Through the intelligent control system, users can adjust the parameters such as fan speed, air volume, and pressure in real time according to actual needs, improving the operational efficiency and flexibility of the ventilation system. For example, in some places that require automatic adjustment of ventilation volume according to environmental changes, such as ventilation systems in smart buildings, the fan can be connected to environmental sensors to automatically adjust its operating status based on indoor temperature, humidity, air quality and other parameters, achieving a perfect balance between energy conservation and comfort.
（4） Wide applicability
Due to its excellent performance characteristics, the K3G280-AU11-C2 centrifugal fan has a wide range of applicability. It can be applied in multiple fields such as industry, commerce, and civilian use. In the industrial field, it can be used for ventilation and exhaust gas treatment in factory workshops; In the commercial field, it can be used for central air conditioning systems, ventilation ducts, etc. in shopping malls and office buildings; In the civilian field, it can be used for ventilation in residential kitchens, bathrooms, etc. It can play an excellent role in both high temperature, humid, and dusty industrial environments, as well as in civilian environments that require high air quality and comfort.
