How to Select Small Industrial Cooling Fans | AC/DC/EC Axial Fan Guide
Deqing Jiefeng Electrical Co., Ltd. (JIEFENGFAN) is a manufacturer engaged in the development, production and sales of industrial axial fans and ventilation/cooling products. Its product range includes AC axial fans, DC axial fans, EC fans, centrifugal fans, outer rotor fans, and cabinet ventilation/filter products for industrial control cabinets, automation equipment, power supplies, communication equipment, energy storage systems, refrigeration equipment and other applications requiring forced-air cooling or ventilation.
When purchasing an industrial cooling fan, do not select by external dimensions alone. Mounting dimensions, rated voltage, airflow, static pressure, speed, noise, operating temperature, IP rating, control functions and system airflow resistance all affect the final choice.
1. Common Industrial Cooling Fan Sizes
JIEFENGFAN industrial axial fan sizes include 8025, 8038, 9225, 9238, 12025, 12038, 13532, 15050, 17238, 17243, 17251, 17255, 18060, 20060, 22060, 22580, 25489 and 28080. Depending on the product series, these sizes may be available as AC, DC or EC models. Always confirm the exact model specifications on the relevant product page.
The digits in a fan size code usually indicate the approximate external size class. For example, 12038 generally refers to approximately 120 × 120 × 38 mm, while 17251 commonly refers to approximately 172 × 150 × 51 mm. Frame shape, mounting-hole layout and actual dimensions can vary, so final installation dimensions must be confirmed from the specific technical drawing.
2. How to Choose AC, DC and EC Cooling Fans
AC Axial Fans
Suitable for industrial equipment powered directly by AC mains. Common supply ratings include AC 220V/230V, while other voltages may be available depending on the model and project requirements. AC axial fans are a common choice for continuous ventilation in industrial control cabinets, machinery and electrical equipment.
DC Axial Fans
Suitable for DC-powered equipment, with common voltages including DC 12V, DC 24V and DC 48V. Depending on the model, options may include PWM speed control, FG speed feedback and RD running/alarm signals. These functions are useful in automation, power electronics, communication, energy storage and equipment requiring fan-status monitoring.
EC Fans
EC fans use electronically commutated motor technology and can combine convenient AC input with electronic control in suitable applications. When energy efficiency, speed control or control integration is required, select the EC model according to the actual power supply, airflow and static-pressure requirements.
3. Key Parameters to Confirm When Purchasing an Industrial Cooling Fan
| Parameter | Why It Matters |
|---|---|
| Mounting Dimensions | Confirms whether the fan fits the equipment |
| Rated Voltage | Confirms AC 220V, DC 24V or other supply conditions |
| Airflow | Determines the volume of air moved |
| Static Pressure | Determines the ability to overcome filters, heat sinks and duct resistance |
| Speed | Related to airflow, static pressure and noise |
| Noise | Important for noise-sensitive equipment |
| Operating Temperature | Confirms suitability for the working environment |
| IP Rating | Relevant for dusty or humid environments |
| Control / Signals | For example PWM, FG and RD |
| Wiring / Mounting | Confirms lead wires, terminals and installation method |
4. What Is the Difference Between Airflow and Static Pressure?
Airflow describes how much air the fan moves over time; static pressure describes the fan's ability to push air against system resistance. In open equipment with low resistance, airflow is often the main concern. If the airflow path includes filters, heat sinks, dense components, narrow passages or long ducts, static pressure must be considered together with airflow.
5. How to Choose Cooling Fans for Different Industrial Equipment
Industrial control cabinets should be evaluated according to cabinet size, internal heat load, ambient temperature, inlet/outlet arrangement and filter resistance. Automation equipment also requires attention to continuous operating time and control functions. Power, communication and electronic equipment often place greater emphasis on size, airflow, noise and signal functions. Energy storage and electrical equipment require a combined assessment of continuous operation, ambient conditions, protection level and airflow-path resistance.
6. How to Choose Between 80 mm, 120 mm and 172 mm Fans
Fan size should not be selected from the equipment's external dimensions alone. First confirm the available mounting space, equipment heat load, allowable temperature rise, target airflow, system resistance and power supply. If the installation space accepts only a 120 mm fan, compare 12025 and 12038 models. If greater airflow or pressure is required, evaluate 150 mm, 172 mm, 200 mm and other sizes.
7. What Is the Difference Between 12038 and 12025 Fans?
12038 and 12025 fans have a similar front-face size class but different thicknesses. A 12038 fan is typically around 38 mm thick, while a 12025 fan is around 25 mm thick. Because motor design, impeller, frame and speed can differ, airflow, static pressure, noise and power can also vary significantly. A thicker fan is not automatically the better choice; selection should be based on system resistance and cooling requirements.
8. How to Choose an Industrial Cooling Fan Manufacturer
- Clear, traceable product model numbers
- Product specifications and technical drawings
- Clearly stated voltage, airflow, static pressure and speed data
- A useful range of sizes and AC/DC/EC product options
- Ability to support selection based on equipment and operating environment
- For long-term OEM projects, consistent product quality and stable supply capability
