EBM Papst, as a leader in the wind turbine industry, has established a good reputation worldwide with years of technological accumulation and innovation capabilities. Its strict control over quality runs through the entire lifecycle of the product, from research and development design to production and manufacturing, striving for excellence in every aspect. The W2D250-GA04-09 axial fan is a powerful witness to the brand's strength, carrying the brand's relentless pursuit of efficient and reliable ventilation solutions.
Rated voltage: 380V rated voltage, suitable for common industrial power environments, ensuring that the fan can be stably connected to the power system, providing stable power guarantee for its continuous and efficient operation. A stable voltage input helps maintain the normal speed and performance of the fan, reducing the risk of equipment failure caused by voltage fluctuations.
Size specification: Designed with a size of 250mm, it ensures sufficient ventilation capacity while also considering installation flexibility. This size can adapt to various installation spaces and structures, whether it is inside narrow equipment or in the ducts of large ventilation systems, suitable installation positions can be found, providing users with more application possibilities.
Maximum air volume: With a maximum air volume of up to 1840m ³/h, this fan demonstrates its powerful ventilation capability. In large industrial plants, commercial complexes and other places that require a large amount of air circulation, it can quickly update the air, discharge polluted air, introduce fresh air, effectively improve indoor air quality, and create a good operating environment for personnel and equipment.
Maximum pressure: The maximum pressure of 111Pa enables it to overcome significant ventilation resistance. In situations where ventilation ducts are long, curved, or equipped with air filtration devices, stable airflow can still be maintained to ensure the normal operation of the ventilation system and meet the needs of different complex ventilation scenarios.
Input power: With an input power of 190W, although the value is not low, combined with its strong ventilation performance, it achieves a high energy conversion efficiency. By optimizing the motor design and aerodynamic structure, electrical energy can be efficiently converted into mechanical energy, ensuring ventilation while reasonably controlling energy consumption, and reducing long-term operating costs for users.
The high speed of 2615rpm is a key factor in achieving high air volume and high pressure. The high-speed rotating blades can quickly promote air flow, improve ventilation efficiency, and meet high requirements for ventilation speed and effectiveness in application scenarios, such as electronic device cooling systems that require timely heat dissipation.
Efficient ventilation: With high speed and optimized blade design, it achieves strong ventilation capacity and can transport a large amount of air in a short period of time, effectively meeting various ventilation needs. Whether it is ventilation and air exchange in large spaces or heat dissipation in equipment that requires high ventilation efficiency, it can perform excellently.
Stable and reliable: Using high-quality materials and advanced manufacturing processes to ensure the stability and reliability of the fan during long-term operation. The motor has undergone rigorous testing and can operate continuously and stably at high speeds, reducing the probability of faults occurring. Meanwhile, the sturdy structural design enables it to withstand a certain degree of external vibration and impact, and adapt to various complex working environments.
Good aerodynamic performance: The blade design has been carefully optimized to have excellent aerodynamic performance. During the rotation process, it can effectively reduce the energy loss of air flow, improve the efficiency of air volume and pressure output, and reduce operating noise (although the noise parameters are not reflected, the design helps to reduce noise generation). Reasonable blade shape and angle make the flow of air between blades smoother, reduce turbulence, and further improve ventilation effectiveness.
Easy installation: The design of the fan fully considers the convenience of installation, with a compact structure and reasonable installation hole design, making it convenient for users to install according to their actual needs. Whether it is wall mounted, ceiling mounted, or embedded installation, it can be easily achieved, reducing the time and labor costs during the installation process.
Industrial plant ventilation: In large industrial plants, equipment operation and personnel activities can generate a large amount of heat, dust, and harmful gases. W2D250-GA04-09 axial flow fan can be installed on the walls, ceilings or ventilation ducts of the factory building. With strong ventilation capacity, it can quickly discharge these pollutants, introduce fresh air, improve the air quality inside the factory building, ensure the health of workers, and provide a good environment for the normal operation of equipment. For example, in electronic manufacturing plants, fans can timely exhaust the smoke and exhaust gas generated during the welding process, ensuring the safety and comfort of the production environment.
Commercial building ventilation: In densely populated commercial buildings such as shopping malls, hotels, and sports centers, high requirements are placed on air quality and comfort. This fan can serve as an important component of the ventilation system, expelling polluted indoor air and introducing fresh air to keep the indoor air fresh. At the same time, in summer, auxiliary air conditioning systems are used to enhance air circulation and improve cooling efficiency; In winter, the auxiliary heating system distributes heat more evenly, providing a comfortable environment for customers and staff. For example, in large shopping malls, it can help the air conditioning system better regulate temperature and enhance customers' shopping experience.
Data center cooling: Data centers typically contain a large number of servers and electronic devices that generate a significant amount of heat during operation. If the heat cannot be dissipated in a timely manner, it will affect the performance and lifespan of the equipment. The W2D250-GA04-09 axial fan can be installed in server cabinets, computer room ventilation ducts, and other locations to quickly dissipate heat through efficient heat dissipation capabilities, ensuring that data center equipment operates at suitable temperatures and guaranteeing stable operation of the data center. In cloud computing data centers, fans can continuously dissipate heat for servers, ensuring efficient data processing.
In summary, the W2D250-GA04-09 axial fan has become a highly competitive product in the fan market due to its excellent parameter performance, significant features, and wide range of application scenarios. Whether it is the large-scale ventilation demand in the industrial sector or the pursuit of comfort in the commercial sector, it can provide efficient and reliable solutions, creating greater value for users.
