120×120×38mm EC Axial Fan | Industrial 12038 EC Cooling Fan
The Hongbo 120×120×38mm EC axial fan is a high-airflow electronically commutated fan designed for industrial applications where energy efficiency and variable-speed control are required. This 120mm EC axial fan uses an EC motor to deliver strong airflow in a standard 120mm form factor while consuming significantly less power than equivalent AC shaded pole fans. It is suited for industrial control cabinets, ventilation panels, and smart cooling systems requiring integrated speed management.
Key Features
- EC Motor for High Efficiency: The electronically commutated motor delivers brushless DC-level efficiency while accepting a wide input voltage range, reducing overall system power consumption.
- Variable Speed Control Compatibility: Supports external speed control via 0–10V analog or PWM signal, enabling demand-based airflow management and reduced energy use during low-load periods.
- High Airflow in 120mm Format: Delivers strong volumetric airflow through a deep 38mm housing, providing higher static pressure capability than thinner 25mm profile variants.
- UL94-V0 Plastic Frame and Impeller: Flame-retardant materials certified for use inside electronic and industrial enclosures.
- Ball and Sleeve Bearing Options: Ball bearing rated for 50,000 hours at 40°C; sleeve bearing available for standard-duty or cost-optimized deployments.
- Low Electrical Noise: Brushless EC motor commutation generates minimal electromagnetic interference, suitable for sensitive industrial electronics.
- Operating Temperature -10°C to +70°C: Compatible with most industrial ambient conditions encountered in control rooms and equipment enclosures.

FAQs
How does an EC fan compare to an AC axial fan of the same size?
An EC fan with the same dimensions typically consumes 20–50% less power than a comparable AC shaded pole fan, and supports external speed control, enabling energy savings during periods of lower thermal demand.
What speed control signals are supported?
EC fans support 0–10V analog and PWM signal control as standard. RS-485 Modbus control is available on selected models for integration with building management or industrial monitoring systems.
Is the 120mm EC fan suitable for outdoor or harsh environments?
The standard model is designed for indoor industrial environments. For outdoor or harsh environments, please contact us about enclosure rating requirements and protective options.
