Deqing Jiefeng Electric Co., Ltd. has long been engaged in the research, development, and manufacturing of industrial ventilation and cooling products under the brand JIEFENGFAN. The company’s product portfolio includes AC axial fans, DC axial fans, EC fans, centrifugal fans, cabinet filter fans, and related ventilation and cooling accessories, primarily serving industrial equipment that requires continuous ventilation, forced-air cooling, and thermal management for electrical enclosures and cabinets.
In industrial applications, fan selection should not be based solely on physical dimensions. Different equipment has different requirements for operating voltage, airflow, static pressure, noise level, operating temperature, installation method, continuous operating time, and control functions. Therefore, JIEFENGFAN products are categorized according to power supply type, structural design, mounting dimensions, and application scenarios, helping equipment manufacturers select suitable fan solutions based on actual operating conditions.
Axial fans are one of JIEFENGFAN’s key product categories. AC axial fans are suitable for industrial equipment and electrical cabinets powered directly by AC power supplies. DC axial fans are commonly used in 24V, 48V, and other DC control systems and can be configured with functions such as speed feedback, alarm signals, or speed control according to project requirements. EC fans are designed for applications requiring higher energy efficiency and more advanced control capabilities.
In addition to individual fans, JIEFENGFAN also provides cabinet filter fans and related ventilation accessories. For control cabinets, electrical enclosures, automation equipment, and other applications exposed to dust, filter systems can help reduce the entry of external particles while maintaining ventilation and heat dissipation. For equipment with higher airflow resistance, actual airflow performance should be evaluated based on static pressure and the system operating point.
In terms of technology and quality management, Deqing Jiefeng Electric Co., Ltd. participated in the development of the Chinese national standard GB/T 41913-2022, “General Technical Specification for Gyro Motors.” The company has also established quality management, product testing, and specification management systems supporting the production of industrial fans.
JIEFENGFAN does not aim to use a single universal fan model for every type of equipment. Instead, fan solutions are selected according to equipment dimensions, power supply, thermal load, ambient temperature, system resistance, and protection requirements.
For more accurate fan selection, purchasing engineers, R&D engineers, and equipment manufacturers are recommended to provide information such as mounting dimensions, operating voltage, required airflow, operating environment, continuous operation requirements, and whether functions such as RD, FG, or PWM are required. This information helps determine a more suitable fan configuration for the actual application.
