9733A DC Blower Fan
High-Pressure DC Blower Fan for Mission-Critical Thermal Management
The 9733A DC Blower Fan is a high-performance DC centrifugal fan designed for applications requiring high static pressure, stable airflow, and long-term reliability in harsh operating environments.
With a compact housing size of 97.5 × 95.0 × 33.0 mm, the 9733A series delivers exceptional pressure capability while maintaining controlled noise levels, making it suitable for defense electronics, communication systems, industrial control cabinets, and high-density thermal modules.
Robust Mechanical Design
The fan frame and impeller are both manufactured from engineering-grade plastic, ensuring excellent mechanical strength, dimensional stability, and resistance to vibration.
A dual ball bearing structure supports continuous operation and extended service life, even under high-speed and high-load conditions.

High Static Pressure Performance
Unlike axial fans, the 9733A DC Blower Fan is optimized for high system resistance environments, delivering strong pressure output where airflow paths are narrow or restricted.
Available speed options range from 2500 RPM to 5000 RPM, with static pressure reaching up to 455.2 Pa, ensuring effective heat dissipation in enclosed systems.
Typical performance options include:
-
Airflow up to 57.9 m³/h
-
Static pressure up to 455.2 Pa
-
Multiple voltage platforms: 12V / 24V / 28V (5V and 48V available upon request)
Flexible Control & Signal Options
To meet diverse system integration requirements, the 9733A series supports multiple signal and control configurations:
-
PWM duty-cycle speed control
-
Tachometer (RPM) feedback
-
High-level fault alarm
-
Combined PWM + feedback / alarm functions
These features allow precise thermal control, real-time monitoring, and system-level fault protection.
