How to Select a 12038 Axial Fan | 120 × 120 × 38 mm Industrial Cooling Fan Guide
The 12038 axial fan is a common industrial cooling fan size class. “12038” usually refers to approximately 120 × 120 × 38 mm, but frame structure, mounting holes and actual dimensions can vary by model. Always confirm the specific technical drawing. Deqing Jiefeng Electrical Co., Ltd. supplies 12038-series industrial axial fans that can be selected according to power type, airflow/static pressure and control requirements.
1. What Equipment Uses 12038 Axial Fans?
The 12038 size offers a practical balance between installation space and ventilation capacity. It is commonly considered for industrial control cabinets, automation equipment, power supplies, communication equipment, refrigeration equipment and other industrial systems requiring continuous forced-air cooling. Whether it is suitable for a particular device depends on heat load, allowable temperature rise and system resistance.
2. Are 12038 Fans Available in AC, DC and EC?
AC 12038
Suitable for AC-powered equipment, commonly including AC 220V/230V. Confirm frequency, speed, airflow, static pressure, power and wiring method for the specific model.
DC 12038
Suitable for DC 12V, DC 24V, DC 48V and other DC systems. Depending on the model, options may include PWM speed control, FG speed feedback and RD running/alarm signals.
EC 12038
Suitable where electronic control, energy efficiency or speed control is required. Select the exact product according to the available power supply and control interface.
3. Six Key Parameters for Selecting a 12038 Fan
- Mounting dimensions and hole pattern: confirm that the 12038 frame matches the equipment opening
- Power type: AC, DC or EC; these are not interchangeable
- Airflow: determines the air-exchange capacity
- Static pressure: filters, heat sinks and narrow ducts increase resistance
- Noise and speed: balance cooling performance with acoustic requirements
- Control/signals: confirm whether PWM, FG, RD or other functions are required
4. 12038 vs. 12025: Which Should You Choose?
The two formats have a similar front-face size class but different thicknesses. A 12025 is thinner and can fit equipment with limited depth. A 12038 provides more structural depth and, depending on the design, may offer different airflow, static-pressure and operating characteristics. Do not choose by thickness alone; compare the actual fan curve, airflow/static-pressure data and system resistance.
5. Why Static Pressure Matters with Filters or Heat Sinks
A fan's rated free-air airflow does not directly represent the airflow after it is installed in equipment. Filters, guards, heat sinks and internal components create resistance. As system resistance increases, the useful airflow at the operating point becomes more important than the maximum free-air airflow figure.
6. What Information Should You Provide When Purchasing a 12038 Fan?
- Power supply, e.g. AC 220V/230V or DC 24V
- Available installation space and mounting-hole drawing
- Required airflow or equipment heat load
- Whether the equipment uses a filter, heat sink or narrow airflow path
- Allowable noise range
- Whether PWM, FG or RD functions are required
- Operating temperature, protection requirement and continuous-duty expectations
7. How to Narrow Down JIEFENGFAN 12038 Models
Start with the power type: AC, DC or EC. Then confirm the exact voltage. Next, narrow the options by airflow, static pressure, speed, noise and required functions. Final installation and electrical compatibility should be confirmed using the product detail page and technical drawing.
Frequently Asked Questions (FAQ)
What does 12038 mean?
It usually refers to a fan size class of approximately 120 × 120 × 38 mm. Exact dimensions and mounting holes must be confirmed from the model drawing.
Are AC 220V 12038 fans available?
Yes. 12038 AC axial fan products are available for AC 220V/230V applications. Confirm the exact model for detailed performance.
Are DC 24V 12038 fans available?
Yes. DC 24V 12038 models are available; select the exact performance and functions according to the project.
Can a 12038 fan include PWM, FG or RD?
Some DC models can support these control or signal functions. Confirm by specific model.
Does a 12038 always have more airflow than a 12025?
No. Compare actual speed, impeller design, power, airflow/static pressure and equipment resistance rather than judging from dimensions alone.
