（1） Rated voltage
The rated voltage of the W3G300-BV25-33 axial fan is 26V. Compared to common high-voltage fans, the lower rated voltage gives it an advantage in terms of safety during use. In some environments with high voltage safety requirements, such as electronic devices and laboratories, a voltage of 26V can effectively reduce the risk of electric shock. At the same time, low voltage operation also helps reduce energy loss and improve the energy utilization efficiency of fans. In addition, it can better match with low-voltage power systems without the need for complex voltage conversion devices, simplifying the power supply system of the equipment.
（2） Size specifications
The size of the fan is 300 millimeters. The moderate size makes it widely applicable. A diameter of 300 millimeters can provide sufficient ventilation area to meet the ventilation needs within a certain spatial range. In industrial equipment, it can be installed in larger chassis or cabinets to provide effective heat dissipation and ventilation for internal electronic components; In commercial places such as small warehouses, exhibition halls, etc., good ventilation can also be achieved. Moreover, this size of fan is relatively flexible in installation and layout, and will not take up too much space.
（3） Maximum air volume
The maximum air volume can reach 3225 cubic meters per hour. Such a large air volume indicates that the fan has strong air transport capability. In scenarios that require rapid ventilation, such as factory workshops, computer rooms, etc., it can quickly exhaust indoor polluted air and introduce fresh air, effectively improving air quality. For servers and other equipment in the computer room, a large air volume can quickly remove the heat generated by the equipment, ensuring that the equipment operates at a suitable temperature and extending its service life.
（4） Maximum pressure
The maximum pressure is 445Pa. Higher pressure means that the fan can overcome greater ventilation resistance. In ventilation systems, the presence of long ventilation ducts, numerous bends, or the installation of air filtration devices can increase the resistance to air flow. The maximum pressure of 445Pa for the W3G300-BV25-33 axial fan ensures that air can still circulate smoothly in these complex ventilation environments, ensuring the stability of the ventilation effect.
（5） Input power
The input power is 380W. Under the condition of ensuring high wind volume and high pressure output, this power consumption is at a relatively reasonable level. Compared to some fans of the same type but with similar performance, it performs well in terms of energy efficiency. Lower input power means that it can save users a lot of electricity expenses and reduce operating costs during long-term use.
（6） Rotational speed
The rotational speed is 3940rpm. A higher rotational speed is one of the important factors for achieving high air volume and high pressure. Through high-speed rotating blades, the fan can accelerate the flow of air, generating strong suction and pressure. However, high speeds may also bring some problems, such as noise and vibration. However, ebm-papst used advanced technology and materials in designing this fan to reduce these adverse effects, ensuring that the fan can still maintain relative stability and quietness at high speeds.
（7） Noise situation
Although the noise (dB) displayed in the parameters is not applicable, ebm-papst adopts a series of noise reduction measures in the actual design and manufacturing process. For example, the shape of the fan blades has been carefully designed with special curves and angles, making the air flow smoother through the blades and reducing turbulence and impact, thereby reducing noise generation. At the same time, the manufacturing process of the motor has also been optimized to reduce vibration and noise propagation during motor operation. In practical use, the noise level of this fan is relatively low and will not cause significant interference to the surrounding environment and the normal operation of equipment.
（1） Efficient Aerodynamic Design
The W3G300-BV25-33 axial fan is designed using advanced aerodynamic principles. The shape and structure of the fan blades have been accurately simulated and optimized, resulting in a streamlined design. This design allows air to form a stable and smooth airflow when passing through the fan blades, reducing energy loss. Compared with traditional axial fans, this fan can generate larger air volume and pressure at the same input power, achieving a significant improvement in ventilation efficiency. At the same time, aerodynamic design also reduces the noise and vibration of the fan during operation, improving the comfort and stability of use.
（2） High quality materials and exquisite craftsmanship
All components of the fan are made of high-quality materials. The fan blades are made of high-strength and lightweight engineering plastics, which have good toughness and wear resistance, and can withstand the centrifugal force generated during high-speed rotation, ensuring the long-term stable operation of the fan blades. The motor adopts high-quality copper windings and high-performance permanent magnets, which have the characteristics of high efficiency and stability. The bearings of the motor adopt high-precision ball bearings, reducing frictional resistance and improving the efficiency and service life of the motor. The casing of the fan is made of sturdy and durable metal material, which has undergone precise processing and surface treatment, and has good corrosion resistance and heat dissipation performance. The exquisite manufacturing process ensures the precision of the fit between various components, reduces vibration and noise caused by excessive clearance between components, and improves the overall performance and reliability of the fan.
（3） Long lifespan and reliability
The W3G300-BV25-33 axial fan has undergone strict quality inspection and reliability testing. The design and manufacturing of key components such as motors and blades fully consider the long-term operational needs. The heat dissipation design of the motor is good, which can timely dissipate the heat generated during operation and avoid damage due to overheating. The material and structural design of the fan blades enable them to have high fatigue resistance and maintain stable performance under long-term high-speed rotation. Under normal usage conditions, the fan has a long service life and can provide users with long-term reliable ventilation services, reducing equipment maintenance costs and downtime.
（4） Easy to install and maintain
The structural design of this fan is simple, easy to install and maintain. Its size is moderate, the weight is light, and the installation process is convenient and fast. Fans are usually equipped with standard installation holes and interfaces, and users can choose the appropriate installation method according to their actual needs. In terms of maintenance, due to the modular design of various components of the fan, it is very easy to replace damaged parts. At the same time, key components such as the motor and blades of the fan have good maintainability, and users can clean and maintain them themselves, reducing maintenance costs and difficulties.
