- Application of School Environment Improvement
（1） Classroom ventilation
The classrooms in schools are the main places for students to study, with dense personnel and easily polluted air. If ventilation is poor, it can lead to issues such as increased carbon dioxide concentration and bacterial transmission, affecting students' physical health and learning efficiency. The W4D300-DT04-09 axial flow fan has a moderate size (300mm) that is suitable for installation on the walls or ceilings of classrooms. Its efficient ventilation capacity can quickly achieve air circulation inside the classroom. The maximum pressure of the fan is 60Pa, which can overcome the resistance of the ventilation duct, introduce fresh air into the classroom, and discharge polluted air. Its 1350rpm speed and low-noise operation characteristics will not affect teachers' teaching and students' learning. At the same time, the intelligent control function of the fan can be connected to the classroom's time control system, automatically turning on ventilation during class and adjusting the speed or turning off according to the actual situation during class to achieve energy-saving operation.
（2） Laboratory ventilation
The school laboratory produces harmful gases and odors during various experiments. W4D300-DT04-09 axial flow fan can be installed in the fume hood and ventilation duct system of the laboratory to timely discharge harmful gases outdoors and protect the health of teachers and students. The high-quality materials and exquisite craftsmanship of the fan ensure its reliability and stability in harsh environments such as chemical corrosion and high temperatures. Its 65W input power is relatively low, which not only meets the ventilation requirements but also reduces the energy consumption cost of the laboratory.
- Application of hospital environment improvement
（1） Ward ventilation
The hospital ward is a place for patients to rest and receive treatment, and a well ventilated environment is crucial for their recovery. W4D300-DT04-09 axial flow fan can be installed near the windows or ventilation openings of the ward to maintain fresh air in the ward through ventilation and air exchange. Its low-noise operation does not affect the patient's rest, creating a quiet and comfortable treatment environment for the patient. The intelligent control function of the fan can be connected to the air quality sensor in the ward, automatically adjusting the fan speed according to the concentration of bacteria, viruses, and harmful gases in the air, ensuring that the air quality in the ward meets hygiene standards.
（2） Ventilation in the operating room
The operating room has extremely high requirements for air quality, requiring strict control of the concentration of bacteria and dust. W4D300-DT04-09 axial flow fan can be used as part of the operating room ventilation system, in conjunction with high-efficiency air filtration equipment. The maximum pressure of the fan is 60Pa, which ensures that the air has sufficient power when passing through the filtering equipment, ensuring the normal operation of the ventilation system. Its long lifespan and reliability characteristics can meet the strict requirements of the operating room for equipment stability, reducing surgical risks caused by equipment failures.
- Application of Library Environment Improvement
（1） Ventilation in the reading room
The reading room of the library is a place for readers to read and learn, with relatively concentrated personnel. W4D300-DT04-09 axial fan can be installed on the top or side of the reading room to achieve effective circulation of indoor air. Its larger size can cover a larger reading area and improve ventilation. The low-noise operation of the fan does not interfere with readers' reading and thinking, providing them with a quiet and comfortable reading environment. At the same time, the energy-saving characteristics of fans can reduce the operating costs of libraries, which is in line with the development concept of green environmental protection.
（2） Ventilation of the library
There are a large number of books stored in the library, and long-term accumulation may produce mold and odors. W4D300-DT04-09 axial fan can be installed in the ventilation system of the library to regularly ventilate and maintain dryness and fresh air inside the library. Its intelligent control function can automatically adjust the running time and speed of the fan according to the humidity and air quality in the library, preventing books from getting damp and moldy, and extending the storage life of books.
- Summary of the advantages of W4D300-DT04-09 axial flow fan in the field of environmental improvement in public places
（1） Performance meets the requirements of the venue
The performance parameters such as size, pressure, speed, and power of the fan can well meet the ventilation needs of different areas in public places. Suitable ventilation solutions can be provided for classrooms, laboratories, wards, operating rooms, reading rooms, and libraries to ensure the environmental quality of public places.
（2） Energy saving and low noise advantages
In public places, energy consumption and noise are key factors to consider. The low input power (65W) of W4D300-DT04-09 axial fan can reduce operating costs, and long-term use can save a lot of energy expenses. Its low-noise operation characteristics will not interfere with personnel activities and rest, creating a quiet and comfortable environment for public places.
（3） Advantages of Intelligent Control and Reliability
The intelligent control function of the fan can automatically adjust the operating status according to the actual environmental parameters of public places, achieving energy-saving and efficient ventilation management. At the same time, its long lifespan and reliability characteristics can ensure long-term stable operation in public places, reduce equipment maintenance costs and failure rates, and ensure the normal operation of ventilation systems.
W4D300-DT04-09 axial flow fans play an important role in improving the environment of public places. As a powerful assistant in improving the environment of public places, it provides people with a healthy, comfortable, and safe public activity space, promoting the sustainable development of public places.
