ebm-papst, as a leading brand in the field of wind turbine manufacturing, is renowned for its innovative technology and excellent quality. The 4D400-AP12-37 axial flow fan is a star product under the brand, designed specifically to meet diverse ventilation needs. It stands out among many similar products with advanced design concepts and exquisite manufacturing techniques, and is widely used in various fields such as industry and commerce.
Rated voltage: The rated voltage is set at 230V, which has strong adaptability and can operate stably in common industrial and commercial power environments. A stable voltage input provides a solid foundation for the reliable operation of the fan, avoiding performance instability or equipment damage caused by voltage fluctuations.
Size specification: The fan size is 400 millimeters, which gives it good versatility due to its moderate size. It will neither occupy too much space due to being too large nor fail to meet ventilation requirements due to being too small. In different installation scenarios, it is easy to find a suitable location for installation.
Maximum air volume: With a maximum air volume of up to 4000m ³/h, it has strong air transport capacity. In a short period of time, it is possible to achieve large-scale air replacement, effectively improve indoor air quality, and provide a comfortable working and living environment for personnel.
Maximum pressure: The maximum pressure reaches 120Pa, which means that the fan can overcome a certain ventilation resistance. In the presence of long ventilation ducts, bends, or obstacles, the smooth flow of air can still be ensured to ensure ventilation effectiveness.
Input power: With an input power of only 185W, it achieves high air volume and high pressure while maintaining low energy consumption. This efficient and energy-saving design not only reduces operating costs, but also meets the modern society's demand for energy-saving and environmentally friendly products.
Speed: A stable 1450rpm speed is the key to achieving efficient ventilation of the fan. The uniform speed ensures the stability of air flow and avoids uneven ventilation caused by speed fluctuations.
Aerodynamic blade design: The blades of the fan are designed using advanced aerodynamic principles. The unique blade shape and angle can maximize air flow efficiency and reduce energy loss during rotation. At the same time, the material of the blades has the characteristics of high strength and lightweight, reducing the load on the motor and improving overall energy efficiency.
Durable and sturdy casing: The casing is made of high-quality metal materials, which have excellent impact resistance and corrosion resistance. It can effectively protect the internal motor and blades, preventing damage to the fan caused by external environmental factors. The sealing design of the shell can also prevent dust and moisture from entering the interior of the fan, extending the service life of the fan.
Efficient motor system: Equipped with high-performance motors, it has the characteristics of high efficiency and stability. The motor adopts advanced insulation technology and heat dissipation design, which can maintain a low temperature during long-term operation, improving the reliability and safety of the motor. At the same time, the starting and stopping process of the motor is smooth, reducing the impact on the power grid.
The 4D400-AP12-37 axial flow fan operates based on the principle of axial flow ventilation. When the motor drives the blades to rotate, the blades apply an axial force to the air, causing it to flow along the axis direction of the fan. Under the action of the blades, air is sucked in from the inlet of the fan, accelerated by the blades, and discharged from the outlet. This axial flow method enables the fan to achieve efficient ventilation and air exchange.
Industrial workshop ventilation: In a large mechanical manufacturing workshop, due to the large amount of heat and dust generated by equipment operation, the air quality is poor. After installing the 4D400-AP12-37 axial flow fan, through reasonable layout and ventilation design, the fan can quickly exhaust the polluted air in the workshop and introduce fresh air. The temperature in the workshop has significantly decreased, and the dust concentration has also dropped significantly, improving the working environment for workers and increasing production efficiency.
Commercial air conditioning: In a large shopping mall, there are dense crowds and poor air circulation. The 4D400-AP12-37 axial flow fan is installed in the ventilation system of the shopping mall, and through continuous ventilation, the air inside the mall remains fresh at all times. Customers feel a more comfortable environment during the shopping process, and the operational efficiency of the mall has also been improved.
In summary, the 4D400-AP12-37 axial flow fan has become an ideal choice in the field of ventilation due to its excellent performance, advanced design, and wide range of application scenarios. Whether in industrial production or commercial operation, it can provide users with reliable and efficient ventilation solutions.
High air volume and efficient ventilation: The maximum air volume of the S4D400-AP12-37 axial flow fan can reach 4000m ³/h, which makes it outstanding in ventilation and air exchange.
