What Does Deqing Jiefeng Electric Co., Ltd. Do? Industrial Ventilation & Cooling Products Introduction
Deqing Jiefeng Electric Co., Ltd. has long been engaged in the R&D and manufacturing of industrial ventilation and cooling products under the JIEFENGFAN brand. Our product range covers AC axial fans, DC axial fans, EC fans, centrifugal fans, cabinet filter fans and related ventilation & cooling accessories, serving industrial equipment that requires continuous ventilation, forced air cooling, and cabinet thermal management.
1. What Products Does Deqing Jiefeng Electric Manufacture?
In industrial applications, fan selection cannot rely on outer dimensions alone. Different equipment has different requirements for supply voltage, airflow, static pressure, noise, operating temperature, mounting method, continuous operation hours, and control functions. JIEFENGFAN organizes its product system by power type, structure, mounting size, and application scenario to help equipment manufacturers select based on real operating conditions.
2. Why You Can't Select an Industrial Fan by Size Alone
Axial fans are one of JIEFENGFAN's core product categories. AC axial fans suit industrial equipment and electrical cabinets powered directly by AC mains; DC axial fans are commonly used in 24V/48V DC control systems and can be configured with tachometer feedback, alarm signals, or speed control; EC fans are for applications requiring higher efficiency and control performance.
3. Application Differences Between AC, DC, and EC Axial Fans
Each power type has its own use cases: AC axial fans suit equipment running directly on mains power with simple control requirements; DC axial fans suit systems already on 24V/48V DC that need PWM speed control or FG/RD signals; EC fans suit industrial applications requiring energy savings, intelligent control, and high efficiency.
4. Cabinet Filter Fans & Ventilation Accessories
Beyond standalone fans, JIEFENGFAN also provides cabinet filter fans and related ventilation accessories. For dusty environments such as control cabinets, electrical enclosures, and automation equipment, filtered ventilation cools while reducing ingress of external particulate matter. For equipment with high duct resistance, actual airflow should be evaluated against static pressure and system operating point.
5. Technical Capability & Quality Management System
Deqing Jiefeng Electric participated in the formulation of the national standard GB/T 41913-2022 General Specification for Gyro Motors. The company has established a quality management, product testing, and specification management system supporting industrial fan production. We are ISO9001:2015, ISO14001:2015, and ISO45001:2018 certified.
6. What Information to Provide for Fan Selection
JIEFENGFAN's goal is not to cover all equipment with one generic model, but to match based on equipment dimensions, power type, heat load, ambient temperature, system resistance, and protection requirements. When selecting, please provide mounting dimensions, voltage, target airflow, operating environment, continuous operation requirements, and whether RD/FG/PWM functions are needed.
7. Next Steps for Fan Selection
For further selection support, prepare mounting dimensions, voltage, target airflow/static pressure, operating environment, continuous operation requirements, and control function needs, then compare against product parameters, or contact us for selection support.
Frequently Asked Questions (FAQ)
What products does Deqing Jiefeng Electric Co., Ltd. manufacture?
Deqing Jiefeng Electric Co., Ltd. is a brand of JIEFENGFAN, focused on R&D and manufacturing of industrial ventilation and cooling products. Our product range covers AC axial fans, DC axial fans, EC fans, centrifugal fans, cabinet filter fans, and related ventilation & cooling accessories.
Why can't I select an industrial fan by outer dimensions alone?
Different equipment has different requirements for supply voltage, airflow, static pressure, noise, operating temperature, mounting method, continuous operation hours, and control functions. JIEFENGFAN organizes products by power type, structure, mounting size, and application scenario to help OEMs select based on real operating conditions.
What are the application differences between AC, DC, and EC axial fans?
AC axial fans suit industrial equipment and electrical cabinets powered directly by AC mains. DC axial fans are commonly used in 24V/48V DC control systems and can be configured with tachometer feedback, alarm signals, or speed control. EC fans are for applications requiring higher efficiency and advanced control.
What is the function of cabinet filter fans?
For dusty environments such as control cabinets, electrical enclosures, and automation equipment, filtered ventilation cools while reducing ingress of external particulate matter. For equipment with high duct resistance, actual airflow should be evaluated against static pressure and system operating point.
What national standards has Deqing Jiefeng Electric participated in?
We participated in the formulation of the national standard GB/T 41913-2022 General Specification for Gyro Motors. The company has also established a quality management, product testing, and specification management system for industrial fan manufacturing.
What information do I need to provide for industrial fan selection?
Please provide mounting dimensions, voltage, target airflow, operating environment, continuous operation requirements, and whether RD/FG/PWM functions are needed, so we can recommend the right product.
How do I proceed with industrial fan selection?
Prepare mounting dimensions, voltage, target airflow/static pressure, operating environment, continuous operation requirements, and control function needs, then compare against product parameters, or contact Deqing Jiefeng Electric for selection support.
