12038B DC Axial Flow Fan
High-Performance Cooling for High-Resistance Systems
In high-density electronic systems, cooling performance depends not only on airflow volume, but on the ability to maintain stable airflow under system resistance.
The 12038B DC Axial Flow Fan (120 × 120 × 38 mm) is designed for such demanding environments, combining high airflow, strong static pressure, and long-term operational reliability.
Engineered for Stability and Durability
The 12038B features an engineering plastic frame and impeller, offering an optimal balance between mechanical strength, weight control, and corrosion resistance.
A dual ball bearing structure ensures long service life and consistent performance under continuous operation.
Strong Performance Across Multiple Voltage Platforms
With speed options up to 11,000 RPM, the 12038B delivers airflow up to 513.9 m³/h and static pressure reaching 1010 Pa, making it well suited for systems with high internal airflow resistance.
Available voltage options include 12V, 24V, 28V, and 48V, supporting a wide range of industrial and defense power architectures.
Signal & Control Flexibility
To meet diverse system integration requirements, the 12038B supports optional signal and control functions, including:
-
PWM duty-cycle speed control
-
Tachometer (RPM) feedback
-
High-level fault alarm
-
Combined PWM + feedback or alarm options
This flexibility allows precise thermal control and real-time system monitoring.
Proven Environmental Adaptability
The 12038B is designed and tested in accordance with GJB military environmental standards, covering:
-
High / low temperature operation
-
Humidity, salt spray, fungus resistance
-
Sand & dust exposure
-
Vibration, shock, acceleration
-
EMC and power supply characteristics
This makes the fan suitable for ground-based, vehicle-mounted, and high-reliability electronic equipment.
