120×120×38mm DC Axial Fan | 12038 DC Cooling Fan for Industrial Systems
The Hongbo 120×120×38mm DC axial fan is a high-capacity brushless fan designed for DC-powered industrial equipment requiring strong forced-air cooling. This 120mm DC axial fan delivers up to 165 CFM (4.67 m³/min) at high speed and is available in 12V, 24V, and 48V configurations. With a UL94-V0 plastic frame, ball and sleeve bearing options, and multiple speed grades, it is suited for demanding industrial electronics, server infrastructure, and large embedded systems.
Key Features
- High Airflow up to 165 CFM: Delivers substantially more airflow than the thinner 25mm profile fans; suited for enclosures with dense component layouts and high heat dissipation.
- Multi-Voltage DC Operation: Available at 12V, 24V, and 48V to align with common industrial DC bus standards and embedded system power rails.
- Brushless DC Motor: Eliminates brush wear; produces lower electrical interference, making it compatible with sensitive electronic environments.
- 38mm Deep Housing: Greater depth provides higher static pressure capability for installations with restricted airflow paths or dense component arrangements.
- UL94-V0 Flame-Retardant Plastics: Both frame and impeller rated UL94-V0 for safe use inside electronic and industrial enclosures.
- Ball Bearing (50,000 hrs) and Sleeve Bearing (30,000 hrs): Ball bearing variant for extended-life applications; sleeve bearing for standard-duty or cost-optimized deployments.
- Multiple Speed Grades: High, medium, and low speed options available to balance airflow output and noise level.

FAQs
How does the 38mm depth compare to the 25mm variant?
The 38mm depth provides significantly higher airflow (up to 165 CFM vs. approximately 54 CFM for the 8025 variant) and better static pressure performance, making it suitable for denser enclosures and greater thermal loads.
What DC voltages are available?
Standard models are available at 12V, 24V, and 48V. Custom voltage ranges are available on request.
Can a tachometer signal be added for speed monitoring?
Yes, tachometer (RPM) signal output is available on selected models. Please specify this when submitting your inquiry.
Do you support OEM orders?
Yes. We support customization of voltage, speed, bearing, lead wire, and packaging. Contact our sales team with your specifications.
