12725A DC Blower Fan
High Static Pressure DC Blower for Demanding Thermal Management
The 12725A DC Blower Fan is a large-format, high-performance DC centrifugal blower designed for applications requiring strong static pressure, stable airflow, and long-term reliability. With a frame size of 127.0 × 127.0 × 25.4 mm, this model is particularly suitable for high-resistance airflow systems in industrial, electronic, and mission-critical environments.

Robust Mechanical Design
The 12725A series adopts a rigid aluminum alloy frame combined with a high-strength engineering plastic impeller, ensuring excellent structural stability while maintaining optimal aerodynamic performance. A dual ball bearing system supports continuous operation and extends service life, even under elevated temperature and vibration conditions.
With a net weight of 360 g, the fan balances mechanical robustness and installation flexibility, making it suitable for fixed installations in control cabinets, power electronics, and cooling modules.
Stable Electrical Performance
The 12725A DC blower fan is available in 12V, 24V, and 28V rated voltage versions, with wide operating voltage ranges to ensure stable operation under fluctuating power conditions. Depending on the selected model, power consumption ranges from 8.0 W to 18.6 W, supporting both energy-efficient and high-output cooling requirements.

High Airflow & Strong Static Pressure
Designed for airflow-resistant systems, the 12725A series delivers airflow up to 80.7 m³/h and static pressure up to 637.6 Pa, making it ideal for applications such as:
-
Enclosed electronic equipment
-
Power supplies and converters
-
Communication and radar subsystems
-
