17251, 22060, and 25489 are common larger-size industrial axial fan specifications. The numbers usually correspond to the outer dimensions and thickness, but size is only a preliminary identifier. You still need to determine the exact model based on voltage, speed, airflow, static pressure, and system resistance. Browse more products: AC axial fan product list.
Size and Airflow Comparison
| Size | Dimensions | Typical Airflow | Typical Pressure | Typical Applications |
|---|---|---|---|---|
| 17251 | 172×150×51 mm | 800-1200 m³/h | 60-120 Pa | Large control cabinets, energy storage cabinets, EV chargers |
| 22060 | 220×220×60 mm | 1500-2200 m³/h | 80-150 Pa | Large cabinets, machinery, ventilation systems |
| 25489 | 254×254×89 mm | 2500-3500 m³/h | 100-200 Pa | Heavy industrial equipment, cooling towers, fresh air systems |
Typical Applications by Size
17251
The 17251 has a relatively compact installation footprint, making it suitable for industrial equipment, power supplies, and control systems that require high ventilation capacity but have limited space. It is a common choice for projects that need to balance structural space and cooling performance.
22060
The 22060 has a larger ventilation cross-section and can be used for large control cabinets, machinery, and other industrial equipment that requires higher air exchange capacity. Since the fan size is larger, confirm mounting holes, protective grilles, wiring harnesses, and maintenance space during structural design.
25489
The 25489 is a larger-size axial fan specification for industrial equipment with high ventilation requirements. In practice, a larger size does not automatically mean it is the better choice — system resistance, noise, and equipment space must all be considered together.
Selection Tip: Compare Airflow-Static Pressure Performance
For all three sizes, we recommend comparing airflow-static pressure performance, not just maximum airflow. If air needs to pass through filters, heat sinks, or long ducts, performance in the high-resistance region is more important.

Frequently Asked Questions
What do the numbers 17251, 22060, and 25489 mean?
The numbers represent the fan's outer dimensions (width × thickness). For example, 17251 = 172mm wide × 51mm thick; 22060 = 220mm wide × 60mm thick; 25489 = 254mm wide × 89mm thick. Larger numbers mean higher airflow, but also larger installation space and higher power consumption.
Does a larger size always mean better cooling?
Not necessarily. If your system resistance is very low (direct ventilation, no filters), a smaller fan may be sufficient. Larger fans also produce more noise and consume more power — choose based on actual cooling requirements and installation space.
Can I directly swap a 17251 for a 22060?
No, you cannot directly swap them. The mounting hole sizes are different: 17251 requires a 177×177mm cutout, while 22060 requires 225×225mm. If you need to change sizes, you will need to re-drill the hole or use an adapter plate.
Are EC versions available for all three sizes?
Yes. EC axial fans are in stock for 17251, and 22060 and 25489 are available for custom order. EC versions support PWM speed control and are 30%+ more energy efficient than AC versions.
Does JIEFENGFAN have stock for all three sizes?
17251 has large stock (AC/DC/EC versions all available). 22060 and 25489 can be custom manufactured with a 2-3 week lead time. Samples ship same day.
